Makefiles: Flatten and sort file lists
I find the big file lists in the Makefiles a bit ugly and not very
practical. Since there are multiple filenames on each line (as much as
fits in 80 columns), it's not easy to add, remove or change a name in
the middle. As a result, we have a mix of long and short lines in no
particular order (ALL_TARGET_OBS is a good example).
I therefore suggest flattening the lists (one name per line) and keeping
them in alphabetical order. The diffs will be much clearer and merge
conflicts will be easier to resolve.
A nice (IMO) side-effect I observed is that the files are compiled
alphabetically by make, so it gives a rough idea of the progress of the
build.
I added a comment in gdb/Makefile.in to mention to keep the file lists
ordered, and gave the general guidelines on what order to respect. I
added a comment in other Makefiles which refers to gdb/Makefile.in, to
avoid duplication.
Running the patch through the buildbot found that gdb.base/default.exp
started to fail. The languages in the error message shown when typing
"set language" have changed order. We could probably improve gdb so
that it prints them in a stable order, regardless of the order of the
object list passed to the linked, but just fixing the test is easier for
now.
New in v2:
- Change ordering style, directories go at the end.
- Cleanup gdbserver's and data-directory's Makefile as well.
- Add comments at top of Makefiles about the ordering.
- Remove wrong trailing backslahes.
- Fix test gdb.base/default.exp.

* Makefile.in: Add comment about file lists ordering.

Add --enable-build-with-cxx configure switch
This new option, disabled by default for now, allows specifying
whether to build GDB, GDBserver, and friends with a C++ (98/03)
compiler.
The name of the switch should be familiar to those who followed GCC's
own C++ conversion process.
. Adding -fpermissive to COMPILER in C++ mode (see the new
build-with-cxx.m4 file) makes errors like these be warnings instead:
gdb/infrun.c:6597:1: error: initializing argument 1 of ‘void sig_print_info(gdb_signal)’ [-fpermissive]
sig_print_info (enum gdb_signal oursig)
^
gdb/infrun.c: In function ‘void do_restore_infcall_suspend_state_cleanup(void*)’:
gdb/infrun.c:7164:39: error: invalid conversion from ‘void*’ to ‘infcall_suspend_state*’ [-fpermissive]
restore_infcall_suspend_state (state);
^
so that the compiler carries on compiling the file. -Werror still
catches the warnings, so nothing is lost, only our lifes are made
easier by concentrating on getting other more important things out of
the way first.
There's no way to quiet those warnings. Until they're all fixed, when
building in C++ mode, -Werror is disabled by default.
. Adding -Wno-narrowing suppresses thousands of instances of this warning:
gdb/arm-linux-tdep.c:439:1: error: narrowing conversion of ‘-1’ from ‘int’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing]
gdb/arm-linux-tdep.c:439:1: error: narrowing conversion of ‘-1l’ from ‘LONGEST {aka long int}’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing]
gdb/arm-linux-tdep.c:450:1: error: narrowing conversion of ‘-1’ from ‘int’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing]
We can defer handling those until we target C++11.
. Adding -Wno-sign-compare suppresses thousands of instances of this warning:
gdb/linux-record.c:1763:32: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
if (tmpulongest == tdep->fcntl_F_GETLK64)
^
. Adding -Wno-write-strings suppresses thousands of instances of this warning:
gdb/mi/mi-cmd-var.c: In function ‘void mi_cmd_var_show_attributes(char*, char**, int)’:
gdb/mi/mi-cmd-var.c:514:12: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings]
attstr = "editable";
^
gdb/mi/mi-cmd-var.c:516:12: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings]
attstr = "noneditable";
^
For now, it's best to hide these warnings from view until we're
'-fpermissive'-clean, and can thus start building with -Werror.
The C compiler has always managed to build working GDBs with these
issues in the code, so a C++ compiler should too.

Move gdbserver to top level
This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.

Move gdbserver to top level
This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.

Add silent Makefile rules
Many projects (e.g. the Linux kernel) and build systems use "silent"
rules, which means that they'll only print a summary of what's being
done instead of printing all the detailed command lines. While chatting
on the #gdb IRC channel, I realized a few people (including me) thought
it would be nice to have it in GDB too.
The idea is that too much text is not useful, the important information
gets lost. If there's only the essential information, it's more likely
to be useful. Most of the time, when I look at the build output, it's
to see how it's progressing. By just printing a brief summary of each
operation, I can easily spot what's currently being compiled and
therefore how the build progresses (with time you know the order in
which files are compiled almost by heart).
As with other projects (Linux, automake-based things, probably others),
it's possible to print the complete command lines by passing V=1 to make
(or any other non-zero value).
I had one hesitation about this: when people report build failures, we
are more likely to miss the full compile command line. We'll probably
sometimes need to ask people to include the build log with "make V=1".
I don't think it's a big downside, if other projects the size of the
Linux kernel can live with it, I'm sure we can too.

gdb, gdbserver, gdbsupport: include early header files with `-include`
The motivation for this change is for analysis tools and IDEs to be
better at analyzing header files on their own.
There are some definitions and includes we want to occur at the very
beginning of all translation units. The way we currently do that is by
requiring all source files (.c and .cc files) to include one of defs.h
(for gdb), server.h (for gdbserver) of common-defs.h (for gdbsupport and
shared source files). These special header files define and include
everything that needs to be included at the very beginning. Other
header files are written in a way that assume that these special
"prologue" header files have already been included.
My problem with that is that my editor (clangd-based) provides a very
bad experience when editing header files. Since clangd doesn't know
that one of defs.h/server.h/common-defs.h was included already, a lot of
things are flagged as errors. For instance, CORE_ADDR is not known.
It's possible to edit the files in this state, but a lot of the power of
the editor is unavailable.
My proposal to help with this is to include those things we always want
to be there using the compilers' `-include` option. Tom Tromey said
that the current approach might exist because not all compilers used to
have an option like this. But I believe that it's safe to assume they
do today.
With this change, clangd picks up the -include option from the compile
command, and is able to analyze the header file correctly, as it sees
all that stuff included or defined by that -include option. That works
because when editing a header file, clangd tries to get the compilation
flags from a source file that includes said header file.
This change is a bit self-serving, because it addresses one of my
frustrations when editing header files, but it might help others too.
I'd be curious to know if others encounter the same kinds of problems
when editing header files. Also, even if the change is not necessary by
any means, I think the solution of using -include for stuff we always
want to be there is more elegant than the current solution.
Even with this -include flag, many header files currently don't include
what they use, but rather depend on files included before them. This
will still cause errors when editing them, but it should be easily
fixable by adding the appropriate include. There's no rush to do so, as
long as the code still compiles, it's just a convenience thing.
The changes are:
- Add the appropriate `-include` option to the various Makefiles.
- There is one particularity for gdbserver's Makefile: we do not want
to include server.h when building `gdbreplay.o`, as `gdbreplay.cc`
doesn't include it. So we can't simply put the `-include` in
`INTERNAL_CFLAGS`. Add the `-include server.h` option to the
`COMPILE` and `IPAGENT_COMPILE` variables, and added a special rule
to compile `gdbreplay.o` with `-include gdbsupport/common-defs.h`.
- Remove the `-include` option from the `check-headers` rule in
gdb/Makefile.in, since it is already included in `INTERNAL_CFLAGS`.

Move gdbsupport to the top level
This patch moves the gdbsupport directory to the top level. This is
the next step in the ongoing project to move gdbserver to the top
level.
The bulk of this patch was created by "git mv gdb/gdbsupport gdbsupport".
This patch then adds a build system to gdbsupport and wires it into
the top level. Then it changes gdb to use the top-level build.
gdbserver, on the other hand, is not yet changed. It still does its
own build of gdbsupport.

Move gdbserver to top level
This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.

gdbserver/linux: probe for libiconv in configure
Make gdbserver's build system locate libiconv when building for Linux.
Commit 07b3255c3bae ("Filter invalid encodings from Linux thread names")
make libiconv madantory for building gdbserver on Linux.
While trying to cross-compile gdb for xtensa-fsf-linux-uclibc (with a
toolchain generated with crosstool-ng), I got:
/home/smarchi/src/binutils-gdb/gdbserver/linux-low.cc:48:10: fatal error: iconv.h: No such file or directory
48 | #include <iconv.h>
| ^~~~~~~~~
I downloaded GNU libiconv, built it for that host, and installed it in
an arbitrary directory. I had to modify the gdbserver build system to
locate libiconv and use it, the result is this patch.
I eventually found that crosstool-ng has a config option to make uclibc
provide an implementation of iconv, which is of course much easier. But
given that this patch is now written, I think it would be worth merging
it, it could help some people who do not have iconv built-in their libc
in the future (and may not have the luxury of rebuilding their libc like
I do).
Using AM_ICONV in configure.ac adds these options for configure (the
same we have for gdb):
--with-libiconv-prefix[=DIR] search for libiconv in DIR/include and DIR/lib
--without-libiconv-prefix don't search for libiconv in includedir and libdir
--with-libiconv-type=TYPE type of library to search for (auto/static/shared)
It sets the `LIBICONV` variable with whatever is needed to link with
libiconv, and adds the necessary `-I` flag to `CPPFLAGS`.
To avoid unnecessarily linking against libiconv on hosts that don't need
it, set `MAYBE_LIBICONV` with the contents of `LIBICONV` only if the
host is Linux, and use `MAYBE_LIBICONV` in `Makefile.in`.
Since libiconv is a hard requirement for Linux hosts, error out if it is
not found.
The bits in acinclude.m4 are similar to what we have in
gdb/acinclude.m4.
Update the top-level build system to support building against an in-tree
libiconv (I did not test this part though). Something tells me that the
all-gdbserver dependency on all-libiconv is unnecessary, since there is
already a dependency of configure-gdbserver on all-libiconv (and
all-gdbserver surely depends on configure-gdbserver). I just copied
what's done for GDB though.
ChangeLog:
* Makefile.def: Add configure-gdbserver and all-gdbserver
dependencies on all-libiconv.
* Makefile.in: Re-generate.

Makefiles: Flatten and sort file lists
I find the big file lists in the Makefiles a bit ugly and not very
practical. Since there are multiple filenames on each line (as much as
fits in 80 columns), it's not easy to add, remove or change a name in
the middle. As a result, we have a mix of long and short lines in no
particular order (ALL_TARGET_OBS is a good example).
I therefore suggest flattening the lists (one name per line) and keeping
them in alphabetical order. The diffs will be much clearer and merge
conflicts will be easier to resolve.
A nice (IMO) side-effect I observed is that the files are compiled
alphabetically by make, so it gives a rough idea of the progress of the
build.
I added a comment in gdb/Makefile.in to mention to keep the file lists
ordered, and gave the general guidelines on what order to respect. I
added a comment in other Makefiles which refers to gdb/Makefile.in, to
avoid duplication.
Running the patch through the buildbot found that gdb.base/default.exp
started to fail. The languages in the error message shown when typing
"set language" have changed order. We could probably improve gdb so
that it prints them in a stable order, regardless of the order of the
object list passed to the linked, but just fixing the test is easier for
now.
New in v2:
- Change ordering style, directories go at the end.
- Cleanup gdbserver's and data-directory's Makefile as well.
- Add comments at top of Makefiles about the ordering.
- Remove wrong trailing backslahes.
- Fix test gdb.base/default.exp.

Makefiles: Flatten and sort file lists
I find the big file lists in the Makefiles a bit ugly and not very
practical. Since there are multiple filenames on each line (as much as
fits in 80 columns), it's not easy to add, remove or change a name in
the middle. As a result, we have a mix of long and short lines in no
particular order (ALL_TARGET_OBS is a good example).
I therefore suggest flattening the lists (one name per line) and keeping
them in alphabetical order. The diffs will be much clearer and merge
conflicts will be easier to resolve.
A nice (IMO) side-effect I observed is that the files are compiled
alphabetically by make, so it gives a rough idea of the progress of the
build.
I added a comment in gdb/Makefile.in to mention to keep the file lists
ordered, and gave the general guidelines on what order to respect. I
added a comment in other Makefiles which refers to gdb/Makefile.in, to
avoid duplication.
Running the patch through the buildbot found that gdb.base/default.exp
started to fail. The languages in the error message shown when typing
"set language" have changed order. We could probably improve gdb so
that it prints them in a stable order, regardless of the order of the
object list passed to the linked, but just fixing the test is easier for
now.
New in v2:
- Change ordering style, directories go at the end.
- Cleanup gdbserver's and data-directory's Makefile as well.
- Add comments at top of Makefiles about the ordering.
- Remove wrong trailing backslahes.
- Fix test gdb.base/default.exp.

Move gdbserver to top level
This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.

gdbserver/csky add csky gdbserver support
Add new files:
gdb/arch/csky.c
gdb/arch/csky.h
gdb/features/cskyv2-linux.c
gdbserver/linux-csky-low.cc
1. In gdb/arch/csky.c file, add function "csky_create_target_description()"
for csky_target::low_arch_setup(). later, it can be used for csky native gdb.
2. In gdb/features/cskyv2-linux.c file, create target_tdesc for csky, include
gprs, pc, hi, lo, float, vector and float control registers.
3. In gdbserver/linux-csky-low.cc file, using PTRACE_GET/SET_RGESET to
get/set registers. The main data structures in asm/ptrace.h are:
struct pt_regs {
unsigned long tls;
unsigned long lr;
unsigned long pc;
unsigned long sr;
unsigned long usp;
/*
* a0, a1, a2, a3:
* r0, r1, r2, r3
*/
unsigned long orig_a0;
unsigned long a0;
unsigned long a1;
unsigned long a2;
unsigned long a3;
/*
* r4 ~ r13
*/
unsigned long regs[10];
/* r16 ~ r30 */
unsigned long exregs[15];
unsigned long rhi;
unsigned long rlo;
unsigned long dcsr;
};
struct user_fp {
unsigned long vr[96];
unsigned long fcr;
unsigned long fesr;
unsigned long fid;
unsigned long reserved;

Makefiles: Flatten and sort file lists
I find the big file lists in the Makefiles a bit ugly and not very
practical. Since there are multiple filenames on each line (as much as
fits in 80 columns), it's not easy to add, remove or change a name in
the middle. As a result, we have a mix of long and short lines in no
particular order (ALL_TARGET_OBS is a good example).
I therefore suggest flattening the lists (one name per line) and keeping
them in alphabetical order. The diffs will be much clearer and merge
conflicts will be easier to resolve.
A nice (IMO) side-effect I observed is that the files are compiled
alphabetically by make, so it gives a rough idea of the progress of the
build.
I added a comment in gdb/Makefile.in to mention to keep the file lists
ordered, and gave the general guidelines on what order to respect. I
added a comment in other Makefiles which refers to gdb/Makefile.in, to
avoid duplication.
Running the patch through the buildbot found that gdb.base/default.exp
started to fail. The languages in the error message shown when typing
"set language" have changed order. We could probably improve gdb so
that it prints them in a stable order, regardless of the order of the
object list passed to the linked, but just fixing the test is easier for
now.
New in v2:
- Change ordering style, directories go at the end.
- Cleanup gdbserver's and data-directory's Makefile as well.
- Add comments at top of Makefiles about the ordering.
- Remove wrong trailing backslahes.
- Fix test gdb.base/default.exp.

Make gdbreplay use more common routines
This makes gdbreplay share a bit more code with gdbserver, and paves
the way to share more in future. Including common-defs.h pulls in
defines and headers that gdb and gdbserver assume are always
defined/available too, such as for example _(), ansidecl.h or a set of
system headers. Including that revealed (static vs extern conflict)
gdbreplay had a local copy of perror_with_name (which exited directly
instead of throwing an error). So I removed gdbreplay's local copy,
and then added enough .o files until gdbreplay linked successfully.
Also, use xstrdup instead of strdup.

2018-06-08 Pedro Alves <palves@redhat.com>
* Makefile.in (GDBREPLAY_OBS): Add common/cleanups.o,
common/common-exceptions.o, common/common-utils.o,

* gdbreplay.c: Include "common-defs.h" instead of the two
'config.h's here. Don't include stdio.h, errno.h, stdlib.h,
string.h or alloca.h.
(perror_with_name): Delete.
(remote_open): Use xstrdup instead of strdup.

# XML files to compile in to gdbserver, if any.

Move gdbserver to top level
This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.

Move gdbserver to top level
This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.

Move gdbserver to top level
This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.

Add silent Makefile rules
Many projects (e.g. the Linux kernel) and build systems use "silent"
rules, which means that they'll only print a summary of what's being
done instead of printing all the detailed command lines. While chatting
on the #gdb IRC channel, I realized a few people (including me) thought
it would be nice to have it in GDB too.
The idea is that too much text is not useful, the important information
gets lost. If there's only the essential information, it's more likely
to be useful. Most of the time, when I look at the build output, it's
to see how it's progressing. By just printing a brief summary of each
operation, I can easily spot what's currently being compiled and
therefore how the build progresses (with time you know the order in
which files are compiled almost by heart).
As with other projects (Linux, automake-based things, probably others),
it's possible to print the complete command lines by passing V=1 to make
(or any other non-zero value).
I had one hesitation about this: when people report build failures, we
are more likely to miss the full compile command line. We'll probably
sometimes need to ask people to include the build log with "make V=1".
I don't think it's a big downside, if other projects the size of the
Linux kernel can live with it, I'm sure we can too.

gnulib: Ensure all libraries are used when building gdb/gdbserver
An issue was reported here related to building GDB on MinGW:
https://sourceware.org/pipermail/gdb/2020-September/048927.html
It was suggested here:
https://sourceware.org/pipermail/gdb/2020-September/048931.html
that the solution might be to make use of $(LIB_GETRANDOM), a variable
defined in the gnulib makefile, when linking GDB.
In fact I think the issue is bigger than just LIB_GETRANDOM. When
using the script binutils-gdb/gnulib/update-gnulib.sh to reimport
gnulib there is a lot of output from gnulib's gnulib-tool. Part of
that output is this:
You may need to use the following makefile variables when linking.
Use them in <program>_LDADD when linking a program, or
in <library>_a_LDFLAGS or <library>_la_LDFLAGS when linking a library.
$(FREXPL_LIBM)
$(FREXP_LIBM)
$(INET_NTOP_LIB)
$(LIBTHREAD)
$(LIB_GETLOGIN)
$(LIB_GETRANDOM)
$(LIB_HARD_LOCALE)
$(LIB_MBRTOWC)
$(LIB_SETLOCALE_NULL)
$(LTLIBINTL) when linking with libtool, $(LIBINTL) otherwise
What I think this is telling us is that we should be including the
value of all these variables on the link line for gdb and gdbserver.
The problem though is that these variables are define in gnulib's
makefile, but are not (necessarily) defined in GDB's makefile.
One solution would be to recreate the checks that gnulib performs in
order to recreate these variables in both gdb's and gdbserver's
makefile. Though this shouldn't be too hard, most (if not all) of
these checks are in the form macros defined in m4 files in the gnulib
tree, so we could just reference these as needed. However, in this
commit I propose a different solution.
Currently, in the top level makefile, we give gdb and gdbserver a
dependency on gnulib. Once gnulib has finished building gdb and
gdbserver can start, these projects then have a hard coded (relative)
path to the compiled gnulib library in their makefiles.
In this commit I extend the gnulib configure script to install a new
makefile fragment in the gnulib build directory. This new file will
have the usual variable substitutions applied to it, and so can
include the complete list (see above) of all the extra libraries that
are needed when linking against gnulib.
In fact the new makefile fragment defines three variables, these are:
LIBGNU: The path to the archive containing gnulib. Can be used as a
dependency as when this file changes gdb/gdbserver should be
relinked.
LIBGNU_EXTRA_LIBS: A list of linker -l.... flags that should be
included in the link line of gdb/gdbserver. These are
libraries that $(LIBGNU) depends on. This list is taken from
the output of gnulib-tool, which is run by our
gnulib/update-gnulib.sh script.
INCGNU: A list of -I.... include paths that should be passed to the
compiler, these are where the gnulib headers can be found.
Now both gdb and gdbserver can include the makefile fragment and make
use of these variables.
The makefile fragment relies on the variable GNULIB_BUILDDIR being
defined. This is checked for in the fragment, and was already defined
in the makefiles of gdb and gdbserver.

gdbserver/linux: probe for libiconv in configure
Make gdbserver's build system locate libiconv when building for Linux.
Commit 07b3255c3bae ("Filter invalid encodings from Linux thread names")
make libiconv madantory for building gdbserver on Linux.
While trying to cross-compile gdb for xtensa-fsf-linux-uclibc (with a
toolchain generated with crosstool-ng), I got:
/home/smarchi/src/binutils-gdb/gdbserver/linux-low.cc:48:10: fatal error: iconv.h: No such file or directory
48 | #include <iconv.h>
| ^~~~~~~~~
I downloaded GNU libiconv, built it for that host, and installed it in
an arbitrary directory. I had to modify the gdbserver build system to
locate libiconv and use it, the result is this patch.
I eventually found that crosstool-ng has a config option to make uclibc
provide an implementation of iconv, which is of course much easier. But
given that this patch is now written, I think it would be worth merging
it, it could help some people who do not have iconv built-in their libc
in the future (and may not have the luxury of rebuilding their libc like
I do).
Using AM_ICONV in configure.ac adds these options for configure (the
same we have for gdb):
--with-libiconv-prefix[=DIR] search for libiconv in DIR/include and DIR/lib
--without-libiconv-prefix don't search for libiconv in includedir and libdir
--with-libiconv-type=TYPE type of library to search for (auto/static/shared)
It sets the `LIBICONV` variable with whatever is needed to link with
libiconv, and adds the necessary `-I` flag to `CPPFLAGS`.
To avoid unnecessarily linking against libiconv on hosts that don't need
it, set `MAYBE_LIBICONV` with the contents of `LIBICONV` only if the
host is Linux, and use `MAYBE_LIBICONV` in `Makefile.in`.
Since libiconv is a hard requirement for Linux hosts, error out if it is
not found.
The bits in acinclude.m4 are similar to what we have in
gdb/acinclude.m4.
Update the top-level build system to support building against an in-tree
libiconv (I did not test this part though). Something tells me that the
all-gdbserver dependency on all-libiconv is unnecessary, since there is
already a dependency of configure-gdbserver on all-libiconv (and
all-gdbserver surely depends on configure-gdbserver). I just copied
what's done for GDB though.
ChangeLog:
* Makefile.def: Add configure-gdbserver and all-gdbserver
dependencies on all-libiconv.
* Makefile.in: Re-generate.

gnulib: Ensure all libraries are used when building gdb/gdbserver
An issue was reported here related to building GDB on MinGW:
https://sourceware.org/pipermail/gdb/2020-September/048927.html
It was suggested here:
https://sourceware.org/pipermail/gdb/2020-September/048931.html
that the solution might be to make use of $(LIB_GETRANDOM), a variable
defined in the gnulib makefile, when linking GDB.
In fact I think the issue is bigger than just LIB_GETRANDOM. When
using the script binutils-gdb/gnulib/update-gnulib.sh to reimport
gnulib there is a lot of output from gnulib's gnulib-tool. Part of
that output is this:
You may need to use the following makefile variables when linking.
Use them in <program>_LDADD when linking a program, or
in <library>_a_LDFLAGS or <library>_la_LDFLAGS when linking a library.
$(FREXPL_LIBM)
$(FREXP_LIBM)
$(INET_NTOP_LIB)
$(LIBTHREAD)
$(LIB_GETLOGIN)
$(LIB_GETRANDOM)
$(LIB_HARD_LOCALE)
$(LIB_MBRTOWC)
$(LIB_SETLOCALE_NULL)
$(LTLIBINTL) when linking with libtool, $(LIBINTL) otherwise
What I think this is telling us is that we should be including the
value of all these variables on the link line for gdb and gdbserver.
The problem though is that these variables are define in gnulib's
makefile, but are not (necessarily) defined in GDB's makefile.
One solution would be to recreate the checks that gnulib performs in
order to recreate these variables in both gdb's and gdbserver's
makefile. Though this shouldn't be too hard, most (if not all) of
these checks are in the form macros defined in m4 files in the gnulib
tree, so we could just reference these as needed. However, in this
commit I propose a different solution.
Currently, in the top level makefile, we give gdb and gdbserver a
dependency on gnulib. Once gnulib has finished building gdb and
gdbserver can start, these projects then have a hard coded (relative)
path to the compiled gnulib library in their makefiles.
In this commit I extend the gnulib configure script to install a new
makefile fragment in the gnulib build directory. This new file will
have the usual variable substitutions applied to it, and so can
include the complete list (see above) of all the extra libraries that
are needed when linking against gnulib.
In fact the new makefile fragment defines three variables, these are:
LIBGNU: The path to the archive containing gnulib. Can be used as a
dependency as when this file changes gdb/gdbserver should be
relinked.
LIBGNU_EXTRA_LIBS: A list of linker -l.... flags that should be
included in the link line of gdb/gdbserver. These are
libraries that $(LIBGNU) depends on. This list is taken from
the output of gnulib-tool, which is run by our
gnulib/update-gnulib.sh script.
INCGNU: A list of -I.... include paths that should be passed to the
compiler, these are where the gnulib headers can be found.
Now both gdb and gdbserver can include the makefile fragment and make
use of these variables.
The makefile fragment relies on the variable GNULIB_BUILDDIR being
defined. This is checked for in the fragment, and was already defined
in the makefiles of gdb and gdbserver.
gdb/ChangeLog:
* Makefile.in: Include Makefile.gnulib.inc. Don't define LIBGNU
or INCGNU. Make use of LIBGNU_EXTRA_LIBS when linking.
gdbserver/ChangeLog:
* Makefile.in: Include Makefile.gnulib.inc. Don't define LIBGNU
or INCGNU. Make use of LIBGNU_EXTRA_LIBS when linking.
gnulib/ChangeLog:
* Makefile.gnulib.inc.in: New file.
* Makefile.in: Regenerate.
* configure: Regenerate.
* configure.ac: Install the new file.

Rename common to gdbsupport
This is the next patch in the ongoing series to move gdbsever to the
top level.
This patch just renames the "common" directory. The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top. This approach makes the patches a bit
more tractable.
I chose the name "gdbsupport" for the directory. However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.
Tested by the buildbot.

Add silent Makefile rules
Many projects (e.g. the Linux kernel) and build systems use "silent"
rules, which means that they'll only print a summary of what's being
done instead of printing all the detailed command lines. While chatting
on the #gdb IRC channel, I realized a few people (including me) thought
it would be nice to have it in GDB too.
The idea is that too much text is not useful, the important information
gets lost. If there's only the essential information, it's more likely
to be useful. Most of the time, when I look at the build output, it's
to see how it's progressing. By just printing a brief summary of each
operation, I can easily spot what's currently being compiled and
therefore how the build progresses (with time you know the order in
which files are compiled almost by heart).
As with other projects (Linux, automake-based things, probably others),
it's possible to print the complete command lines by passing V=1 to make
(or any other non-zero value).
I had one hesitation about this: when people report build failures, we
are more likely to miss the full compile command line. We'll probably
sometimes need to ask people to include the build log with "make V=1".
I don't think it's a big downside, if other projects the size of the
Linux kernel can live with it, I'm sure we can too.

Move gdbserver to top level
This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.

Add silent Makefile rules
Many projects (e.g. the Linux kernel) and build systems use "silent"
rules, which means that they'll only print a summary of what's being
done instead of printing all the detailed command lines. While chatting
on the #gdb IRC channel, I realized a few people (including me) thought
it would be nice to have it in GDB too.
The idea is that too much text is not useful, the important information
gets lost. If there's only the essential information, it's more likely
to be useful. Most of the time, when I look at the build output, it's
to see how it's progressing. By just printing a brief summary of each
operation, I can easily spot what's currently being compiled and
therefore how the build progresses (with time you know the order in
which files are compiled almost by heart).
As with other projects (Linux, automake-based things, probably others),
it's possible to print the complete command lines by passing V=1 to make
(or any other non-zero value).
I had one hesitation about this: when people report build failures, we
are more likely to miss the full compile command line. We'll probably
sometimes need to ask people to include the build log with "make V=1".
I don't think it's a big downside, if other projects the size of the
Linux kernel can live with it, I'm sure we can too.

to be useful. Most of the time, when I look at the build output, it's
to see how it's progressing. By just printing a brief summary of each
operation, I can easily spot what's currently being compiled and
therefore how the build progresses (with time you know the order in
which files are compiled almost by heart).
As with other projects (Linux, automake-based things, probably others),
it's possible to print the complete command lines by passing V=1 to make
(or any other non-zero value).
I had one hesitation about this: when people report build failures, we
are more likely to miss the full compile command line. We'll probably
sometimes need to ask people to include the build log with "make V=1".
I don't think it's a big downside, if other projects the size of the
Linux kernel can live with it, I'm sure we can too.

Move gdbserver to top level
This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.

gdbserver: pass osabi to GDB in more target descriptions
Problem Description
-------------------
On a Windows machine I built gdbserver, configured for the target
'x86_64-w64-mingw32', then on a GNU/Linux machine I built GDB with
support for all target (--enable-targets=all).
On the Windows machine I start gdbserver with a small test binary:
$ gdbserver 192.168.129.25:54321 C:\some\directory\executable.exe
On the GNU/Linux machine I start GDB without the test binary, and
connect to gdbserver.
As I have not given GDB the test binary, my expectation is that GDB
would connect to gdbserver and then download the file over the remote
protocol, but instead I was presented with this message:
(gdb) target remote 192.168.129.25:54321
Remote debugging using 192.168.129.25:54321
warning: C:\some\directory\executable.exe: No such file or directory.
0x00007ffa3e1e1741 in ?? ()
(gdb)
What I found is that if I told GDB where to find the binary, like
this:
(gdb) file target:C:/some/directory/executable.exe
A program is being debugged already.
Are you sure you want to change the file? (y or n) y
Reading C:/some/directory/executable.exe from remote target...
warning: File transfers from remote targets can be slow. Use "set sysroot" to access files locally instead.
Reading C:/some/directory/executable.exe from remote target...
Reading symbols from target:C:/some/directory/executable.exe...
(gdb)
then GDB would download the executable.
The Actual Issue
----------------
I tracked the problem down to exec_file_find (solib.c). The remote
target was passing an absolute Windows filename (beginning with "C:/"
in this case), but in exec_file_find GDB was failing the
IS_TARGET_ABSOLUTE_PATH call, and so was treating the filename as
relative.
The IS_TARGET_ABSOLUTE_PATH call was failing because GDB thought that
the file system kind was "unix", and as the filename didn't start with
a "/" it assumed the filename was not absolute.
But I'm connecting to a Windows target and 'target-file-system-kind'
was set to "auto", so GDB should be figuring out that the target
file-system is "dos-based".
Looking in effective_target_file_system_kind (filesystem.c), we find
that the logic of "auto" is delegated to the current gdbarch. However
in windows-tdep.c we see:
set_gdbarch_has_dos_based_file_system (gdbarch, 1);
So if we are using a Windows gdbarch we should have "dos-based"
filesystems. What this means is that after connecting to the remote
target GDB has selected the wrong gdbarch.
What's happening is that the target description sent back by the
remote target only includes the x86-64 registers. There's no
information about which OS we're on. As a consequence, GDB picks the
first x86-64 gdbarch which can handle the provided register set, which
happens to be a GNU/Linux gdbarch.
And indeed, there doesn't appear to be anywhere in gdbserver that sets
the osabi on the target descriptions. Some target descriptions do have
their osabi set when the description is created, e.g. in:
gdb/arch/amd64.c - Sets GNU/Linux osabi when appropriate.
gdb/arch/i386.c - Likewise.
gdb/arch/tic6x.c - Always set GNU/Linux osabi.
There are also some cases in gdb/features/*.c where the tdesc is set,
but these locations are only called from GDB, not from gdbserver.
This means that many target descriptions are created without an osabi,
gdbserver does nothing to fix this, and the description is returned to
GDB without an osabi included. This leaves GDB having to guess what
the target osabi is, and in some cases, GDB can get this wrong.
Proposed Solution
-----------------
I propose to change init_target_desc so that it requires an gdb_osabi
to be passed in, this will then be used to set the target_desc osabi
field.
I believe that within gdbserver init_target_desc is called for every
target_desc, so this should mean that every target_desc has an
opportunity to set the osabi to something sane.
I did consider passing the osabi into the code which creates the
target_desc objects, but that would require updating far more code, as
each target has its own code for creating target descriptions.
The approach taken here requires minimal changes and forces every
user of init_target_desc to think about what the correct osabi is.
In some cases, e.g. amd64, where the osabi is already set when the
target_desc is created, the init_target_desc call will override the
current value, however, we should always be replacing it with the same
actual value. i.e. if the target_desc is created with the osabi set
to GNU/Linux, then this should only happen when gdbserver is built for
GNU/Linux, in which case the init_target_desc should also be setting
the osabi to GNU/Linux.
The Tricky Bits
---------------
Some targets, like amd64, use a features based approach for creating
target_desc objects, there's a function in arch/amd64.c which creates
a target_desc, adds features too it, and returns the new target_desc.
This target_desc is then passed to an init_target_desc call within
gdbserver. This is the easy case to handle.
Then there are other targets which instead have a fixed set of xml
files, each of which is converted into a .dat file, which is then used
to generate a .cc file, which is compiled into gdbserver. The
generated .cc file creates the target_desc object and calls
init_target_desc on it. In this case though the target description
that is sent to GDB isn't generated from the target_desc object, but
is instead the contents of the fixed xml file. For this case the
osabi which we pass to init_target_desc should match the osabi that
exists in the fixed xml file.
Luckily, in the previous commit I copied the osabi information from
the fixed xml files into the .dat files. So in this commit I have
extended regdat.sh to read the osabi from the .dat file and use it in
the generated init_target_desc call.
The problem with some of these .dat base targets is that their fixed
xml files don't currently contain any osabi information, and the file
names don't indicate that they are Linux only (despite them currently
only being used from gdbserver for Linux targets), so I don't
currently feel confident adding any osabi information to these files.
An example would be features/rs6000/powerpc-64.xml. For now I've just
ignored these cases. The init_target_desc will use GDB_OSABI_UNKNOWN
which is the default. This means that for these targets nothing
changes from the current behaviour. But many other targets do now
pass the osabi back. Targets that do pass the osabi back are
improved with this commit.
Conclusion
----------
Now when I connect to the Windows remote the target description
returned includes the osabi name. With this extra information GDB
selects the correct gdbarch object, which means that GDB understands
the target has a "dos-based" file-system. With that correct GDB
understands that the filename it was given is absolute, and so fetches
the file from the remote as we'd like.

gdb, gdbserver, gdbsupport: include early header files with `-include`
The motivation for this change is for analysis tools and IDEs to be
better at analyzing header files on their own.
There are some definitions and includes we want to occur at the very
beginning of all translation units. The way we currently do that is by
requiring all source files (.c and .cc files) to include one of defs.h
(for gdb), server.h (for gdbserver) of common-defs.h (for gdbsupport and
shared source files). These special header files define and include
everything that needs to be included at the very beginning. Other
header files are written in a way that assume that these special
"prologue" header files have already been included.
My problem with that is that my editor (clangd-based) provides a very
bad experience when editing header files. Since clangd doesn't know
that one of defs.h/server.h/common-defs.h was included already, a lot of
things are flagged as errors. For instance, CORE_ADDR is not known.
It's possible to edit the files in this state, but a lot of the power of
the editor is unavailable.
My proposal to help with this is to include those things we always want
to be there using the compilers' `-include` option. Tom Tromey said
that the current approach might exist because not all compilers used to
have an option like this. But I believe that it's safe to assume they
do today.
With this change, clangd picks up the -include option from the compile
command, and is able to analyze the header file correctly, as it sees
all that stuff included or defined by that -include option. That works
because when editing a header file, clangd tries to get the compilation
flags from a source file that includes said header file.
This change is a bit self-serving, because it addresses one of my
frustrations when editing header files, but it might help others too.
I'd be curious to know if others encounter the same kinds of problems
when editing header files. Also, even if the change is not necessary by
any means, I think the solution of using -include for stuff we always
want to be there is more elegant than the current solution.
Even with this -include flag, many header files currently don't include
what they use, but rather depend on files included before them. This
will still cause errors when editing them, but it should be easily
fixable by adding the appropriate include. There's no rush to do so, as
long as the code still compiles, it's just a convenience thing.
The changes are:
- Add the appropriate `-include` option to the various Makefiles.
- There is one particularity for gdbserver's Makefile: we do not want
to include server.h when building `gdbreplay.o`, as `gdbreplay.cc`
doesn't include it. So we can't simply put the `-include` in
`INTERNAL_CFLAGS`. Add the `-include server.h` option to the
`COMPILE` and `IPAGENT_COMPILE` variables, and added a special rule
to compile `gdbreplay.o` with `-include gdbsupport/common-defs.h`.
- Remove the `-include` option from the `check-headers` rule in
gdb/Makefile.in, since it is already included in `INTERNAL_CFLAGS`.

Move gdbserver to top level
This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.

gdbsupport: rename source files to .cc
This patch renames the .c source files in gdbsupport to .cc.
In the gdb directory, there is an argument against renaming the source
files, which is that it makes using some git commands more difficult to
do archeology. Some commands have some kind of "follow" option that
makes git try to follow renames, but it doesn't work in all situations.
Given that we have just moved the gdbsupport directory, that argument
doesn't hold for source files in that directory. I therefore suggest
renaming them to .cc, so that they are automatically recognized as C++
by various tools and editors.
The original motivation behind this is that when building gdbsupport
with clang, I get:
CC agent.o
clang: error: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated [-Werror,-Wdeprecated]
In the gdb/ directory, we make clang happy by passing "-x c++". We
could do this in gdbsupport too, but I think that renaming the files is
a better long-term solution.
gdbserver still does its own build of gdbsupport, so a few changes in
its Makefile are necessary.
gdbsupport/ChangeLog:
* Makefile.am: Rename source files from .c to .cc.
(CC, CFLAGS): Don't override.
(AM_CFLAGS): Rename to ...
(AM_CXXFLAGS): ... this.
* Makefile.in: Re-generate.
* %.c: Rename to %.cc.
gdbserver/ChangeLog:
* Makefile.in: Rename gdbsupport source files from .c to .cc.

This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.

gdbserver: pass osabi to GDB in more target descriptions
Problem Description
-------------------
On a Windows machine I built gdbserver, configured for the target
'x86_64-w64-mingw32', then on a GNU/Linux machine I built GDB with
support for all target (--enable-targets=all).
On the Windows machine I start gdbserver with a small test binary:
$ gdbserver 192.168.129.25:54321 C:\some\directory\executable.exe
On the GNU/Linux machine I start GDB without the test binary, and
connect to gdbserver.
As I have not given GDB the test binary, my expectation is that GDB
would connect to gdbserver and then download the file over the remote
protocol, but instead I was presented with this message:
(gdb) target remote 192.168.129.25:54321
Remote debugging using 192.168.129.25:54321
warning: C:\some\directory\executable.exe: No such file or directory.
0x00007ffa3e1e1741 in ?? ()
(gdb)
What I found is that if I told GDB where to find the binary, like
this:
(gdb) file target:C:/some/directory/executable.exe
A program is being debugged already.
Are you sure you want to change the file? (y or n) y
Reading C:/some/directory/executable.exe from remote target...
warning: File transfers from remote targets can be slow. Use "set sysroot" to access files locally instead.
Reading C:/some/directory/executable.exe from remote target...
Reading symbols from target:C:/some/directory/executable.exe...
(gdb)
then GDB would download the executable.
The Actual Issue
----------------
I tracked the problem down to exec_file_find (solib.c). The remote
target was passing an absolute Windows filename (beginning with "C:/"
in this case), but in exec_file_find GDB was failing the
IS_TARGET_ABSOLUTE_PATH call, and so was treating the filename as
relative.
The IS_TARGET_ABSOLUTE_PATH call was failing because GDB thought that
the file system kind was "unix", and as the filename didn't start with
a "/" it assumed the filename was not absolute.
But I'm connecting to a Windows target and 'target-file-system-kind'
was set to "auto", so GDB should be figuring out that the target
file-system is "dos-based".
Looking in effective_target_file_system_kind (filesystem.c), we find
that the logic of "auto" is delegated to the current gdbarch. However
in windows-tdep.c we see:
set_gdbarch_has_dos_based_file_system (gdbarch, 1);
So if we are using a Windows gdbarch we should have "dos-based"
filesystems. What this means is that after connecting to the remote
target GDB has selected the wrong gdbarch.
What's happening is that the target description sent back by the
remote target only includes the x86-64 registers. There's no
information about which OS we're on. As a consequence, GDB picks the
first x86-64 gdbarch which can handle the provided register set, which
happens to be a GNU/Linux gdbarch.
And indeed, there doesn't appear to be anywhere in gdbserver that sets
the osabi on the target descriptions. Some target descriptions do have
their osabi set when the description is created, e.g. in:
gdb/arch/amd64.c - Sets GNU/Linux osabi when appropriate.
gdb/arch/i386.c - Likewise.
gdb/arch/tic6x.c - Always set GNU/Linux osabi.
There are also some cases in gdb/features/*.c where the tdesc is set,
but these locations are only called from GDB, not from gdbserver.
This means that many target descriptions are created without an osabi,
gdbserver does nothing to fix this, and the description is returned to
GDB without an osabi included. This leaves GDB having to guess what
the target osabi is, and in some cases, GDB can get this wrong.
Proposed Solution
-----------------
I propose to change init_target_desc so that it requires an gdb_osabi
to be passed in, this will then be used to set the target_desc osabi
field.
I believe that within gdbserver init_target_desc is called for every
target_desc, so this should mean that every target_desc has an
opportunity to set the osabi to something sane.
I did consider passing the osabi into the code which creates the
target_desc objects, but that would require updating far more code, as
each target has its own code for creating target descriptions.
The approach taken here requires minimal changes and forces every
user of init_target_desc to think about what the correct osabi is.
In some cases, e.g. amd64, where the osabi is already set when the
target_desc is created, the init_target_desc call will override the
current value, however, we should always be replacing it with the same
actual value. i.e. if the target_desc is created with the osabi set
to GNU/Linux, then this should only happen when gdbserver is built for
GNU/Linux, in which case the init_target_desc should also be setting
the osabi to GNU/Linux.
The Tricky Bits
---------------
Some targets, like amd64, use a features based approach for creating
target_desc objects, there's a function in arch/amd64.c which creates
a target_desc, adds features too it, and returns the new target_desc.
This target_desc is then passed to an init_target_desc call within
gdbserver. This is the easy case to handle.
Then there are other targets which instead have a fixed set of xml
files, each of which is converted into a .dat file, which is then used
to generate a .cc file, which is compiled into gdbserver. The
generated .cc file creates the target_desc object and calls
init_target_desc on it. In this case though the target description
that is sent to GDB isn't generated from the target_desc object, but
is instead the contents of the fixed xml file. For this case the
osabi which we pass to init_target_desc should match the osabi that
exists in the fixed xml file.
Luckily, in the previous commit I copied the osabi information from
the fixed xml files into the .dat files. So in this commit I have
extended regdat.sh to read the osabi from the .dat file and use it in
the generated init_target_desc call.
The problem with some of these .dat base targets is that their fixed
xml files don't currently contain any osabi information, and the file
names don't indicate that they are Linux only (despite them currently
only being used from gdbserver for Linux targets), so I don't
currently feel confident adding any osabi information to these files.
An example would be features/rs6000/powerpc-64.xml. For now I've just
ignored these cases. The init_target_desc will use GDB_OSABI_UNKNOWN
which is the default. This means that for these targets nothing
changes from the current behaviour. But many other targets do now
pass the osabi back. Targets that do pass the osabi back are
improved with this commit.
Conclusion
----------
Now when I connect to the Windows remote the target description
returned includes the osabi name. With this extra information GDB
selects the correct gdbarch object, which means that GDB understands
the target has a "dos-based" file-system. With that correct GDB
understands that the filename it was given is absolute, and so fetches
the file from the remote as we'd like.

gdb, gdbserver, gdbsupport: include early header files with `-include`
The motivation for this change is for analysis tools and IDEs to be
better at analyzing header files on their own.
There are some definitions and includes we want to occur at the very
beginning of all translation units. The way we currently do that is by
requiring all source files (.c and .cc files) to include one of defs.h
(for gdb), server.h (for gdbserver) of common-defs.h (for gdbsupport and
shared source files). These special header files define and include
everything that needs to be included at the very beginning. Other
header files are written in a way that assume that these special
"prologue" header files have already been included.
My problem with that is that my editor (clangd-based) provides a very
bad experience when editing header files. Since clangd doesn't know
that one of defs.h/server.h/common-defs.h was included already, a lot of
things are flagged as errors. For instance, CORE_ADDR is not known.
It's possible to edit the files in this state, but a lot of the power of
the editor is unavailable.
My proposal to help with this is to include those things we always want
to be there using the compilers' `-include` option. Tom Tromey said
that the current approach might exist because not all compilers used to
have an option like this. But I believe that it's safe to assume they
do today.
With this change, clangd picks up the -include option from the compile
command, and is able to analyze the header file correctly, as it sees
all that stuff included or defined by that -include option. That works
because when editing a header file, clangd tries to get the compilation
flags from a source file that includes said header file.
This change is a bit self-serving, because it addresses one of my
frustrations when editing header files, but it might help others too.
I'd be curious to know if others encounter the same kinds of problems
when editing header files. Also, even if the change is not necessary by
any means, I think the solution of using -include for stuff we always
want to be there is more elegant than the current solution.
Even with this -include flag, many header files currently don't include
what they use, but rather depend on files included before them. This
will still cause errors when editing them, but it should be easily
fixable by adding the appropriate include. There's no rush to do so, as
long as the code still compiles, it's just a convenience thing.
The changes are:
- Add the appropriate `-include` option to the various Makefiles.
- There is one particularity for gdbserver's Makefile: we do not want
to include server.h when building `gdbreplay.o`, as `gdbreplay.cc`
doesn't include it. So we can't simply put the `-include` in
`INTERNAL_CFLAGS`. Add the `-include server.h` option to the
`COMPILE` and `IPAGENT_COMPILE` variables, and added a special rule
to compile `gdbreplay.o` with `-include gdbsupport/common-defs.h`.
- Remove the `-include` option from the `check-headers` rule in
gdb/Makefile.in, since it is already included in `INTERNAL_CFLAGS`.

Makefiles: Disable suffix rules and implicit rules
Since we don't use suffix rules nor implicit rules in gdb, we can
disable them. The advantage is a slightly faster make [1].
Here are some numbers about the speedup. I ran this on my trusty old
Intel Q6600, so the time numbers are probably higher than what you'd get
on any recent hardware. I ran "make" in the gdb/ directory of an
already built repository (configured with --enable-targets=all). I
recorded the time of execution (average of 5). I then ran "make -d" and
recorded the number of printed lines, which gives a rough idea of the
number of operations done.
I compared the following configurations, to see the impact of both the
empty .SUFFIXES target and the empty pattern rules, as well as running
"make -r", which can be considered the "ideal" case.
A - baseline
B - baseline + .SUFFIXES
C - baseline + pattern rules
D - baseline + .SUFFIXES + pattern rules
E - baseline + make -r
config | time (s) | "make -d"
-----------------------------
A | 5.74 | 2396643
B | 1.19 | 298469
C | 2.81 | 1266573
D | 1.13 | 245489
E | 1.01 | 163914
We can see that the empty .SUFFIXES target has a bigger impact than the
empty pattern rules, but still it doesn't hurt to disable the implicit
pattern rules as well.
There are still some mentions of implicit rules I can't get rid of in
the "make -d" output. For example, it's trying to build .c files from
.w files:
Looking for an implicit rule for '/home/simark/src/binutils-gdb/gdb/infrun.c'.
Trying pattern rule with stem 'infrun'.
Trying implicit prerequisite '/home/simark/src/binutils-gdb/gdb/infrun.w'.
and trying to build Makefile.in from a bunch of extensions:
Looking for an implicit rule for 'Makefile.in'.
Trying pattern rule with stem 'Makefile.in'.
Trying implicit prerequisite 'Makefile.in.o'.
Trying pattern rule with stem 'Makefile.in'.
Trying implicit prerequisite 'Makefile.in.c'.
Trying pattern rule with stem 'Makefile.in'.
Trying implicit prerequisite 'Makefile.in.cc'.
... many more ...
If somebody knows how to disable them, we can do it, but at this point
the returns are minimal, so it is not that important.
I verified that both in-tree and out-of-tree builds work.
[1] Switching from explicit rules to pattern rules for files in
subdirectories actually made it slower, so this is kind of a way to
redeem myself. But it the end it's faster than it was previously,
so it was all worth it. :)

# Disable implicit make rules.

Move gdbserver to top level
This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.
