An earlier patch of mine changed parse_traceframe_info to make it return
a unique_ptr. I forgot to update the version of the function used in an
expat-less build, this patch fixes it.

Remove the usage of inferior_list for the all_threads list in
gdbserver. The entry field in thread_info is removed, and replaced by a
simple ptid field.
I added some functions to iterate (for_each_thread) and find threads
(find_thread). However, changing all the users of find_inferior & co to
use these new functions would have made the patch way too big. So I
opted instead to make find_inferior & co some shims, so that the
existing code only needs to be updated minimally. We can then update
the existing code to use the new functions incrementally (I've started
to do the work, but I'll post it afterwards, see [1] if you want a peek).
This patch has been built-tested on all relevant platforms, except
lynx. I also regtested using the native-gdbserver and
native-extended-gdbserver boards on x86.

As a small step towards removing inferior_list/inferior_list_entry, this
patch replaces the usage of inferior_list for the list of dlls by an
std::list. The dll_info type now uses an std::string for name and has a
simple constructor.
I am able to build gdbserver with mingw on Linux, but I am not able to
test this on a Windows machine (the only platform that uses this code).

Since this target method returns an allocated object, return a
unique_ptr. It allows getting rid a some cleanups here and there.
I had to shuffle the includes around. First, target.h now needs to
include tracepoint.h, to get the definition of traceframe_info_up.
However, the definition of enum trace_find_type was later in target, so
I had to move it to tracepoint.h, so that the declaration of tfind_1
could know about it. I then had to remove the include of target.h from
tracepoint.h, which caused a circular dependency (it was probably
included to get enum trace_find_type in the first place anyway).
Regression tested on the buildbot.
gdb/ChangeLog:
* target.h: Include tracepoint.h.
(enum trace_find_type): Move to tracepoint.h.
(struct target_ops) <to_traceframe_info>: Return a unique ptr.

Straightforward change from a VEC to std::vector. This allows making
the destruction of a traceframe_info trivial.
I added a constructor with parameters to mem_range to be able to
emplace_back directly with the values. It is necessary to leave a
default constructor there because mem_range is still used in a VEC.
gdb/ChangeLog:
* memrange.h (struct mem_range): Add constructors.
* tracepoint.h (struct traceframe_info) <memory>: Change type to
std::vector<mem_range>.
* tracepoint.c (free_traceframe_info): Don't manually free

(traceframe_available_memory): Likewise.
* tracefile-tfile.c (build_traceframe_info): Likewise.
* ctf.c (ctf_traceframe_info): Likewise.
Straightforward change to get rid of a VEC. We need to new/delete
traceframe_info instead of malloc/free it. I found three places that
allocate a traceframe_info (ctf_traceframe_info, tfile_traceframe_info
and parse_traceframe_info) and only one that frees it
(free_traceframe_info).
gdb/ChangeLog:
* tracepoint.h (struct traceframe_info) <tvars>: Change type to
std::vector<int>.
* tracepoint.c (free_traceframe_info): Deallocate with delete.

This simplifies the code quite a bit, by removing the array of PID_T
that's actually an array of pairs of PID_T.
This code is only used to implement "info os procgroups". I tested by hand

psymbol_allocation_list is basically a vector implementation. We can
replace it with an std::vector, now that objfile has been C++-ified.
I sent this to the buildbot, there are a few suspicious failures, but
I don't think they are related to this patch. For example on powerpc:
new FAIL: gdb.base/catch-syscall.exp: execve: syscall execve has returned
new FAIL: gdb.base/catch-syscall.exp: execve: continue to main
new FAIL: gdb.base/catch-syscall.exp: execve: continue until exit

patch.

Replace this usage of GROW_VECT with an std::string. I don't think
there's a reason for this variable to be static, other than it was
cumbersome to manage its lifetime (i.e. use a cleanup) before.

patch.
gdb/ChangeLog:
* ada-typeprint.c (print_dynamic_range_bound): Use std::string.
These tests want to use raw "run", so skip them on targets that can't
do that.
Also adds a small utility procedure that clearly conveys intent instead of
explicitly checking use_gdb_stub in the testcases.
This makes sure these testcases continue to be skipped with
--target_board=native-gdbserver once that board stops setting
is_remote.

FAIL: gdb.base/testenv.exp: test with TEST_GDB_GLOBAL unset
The problem is that the testcase relies on stdio. While we could fix
this for gdbserver by read output from inferior_spawn_id, a better fix
it to not rely on stdio at all. That's what this commit does.
Instead, it reads variables off of the inferior to extract the
necessary information.
Along the way, most of the .exp file is reimplemented/cleaned up using
more modern mechanisms. E.g., with_test_prefix, proc_with_prefix,
save_vars, etc. Also, a missing check for "is_remote host" is added.

If we make the native-gdbserver board be !is_remote, then the few
tests that use the selftest-support.exp routines to debug gdb itself
start running, and fail, with something like:
Running ..../src/gdb/testsuite/gdb.gdb/selftest.exp ...
ERROR: tcl error sourcing ..../src/gdb/testsuite/gdb.gdb/selftest.exp.
ERROR: gdbserver does not support run [....] without extended-remote
while executing
"error "gdbserver does not support $command without extended-remote""

invoked from within

-re "Starting program.*Breakpoint \[0-9\]+,.*$function \\(\\).* at .*main.c:.*$gdb..."
(procedure "selftest_setup" line 45)
This commit makes sure those tests continue to be skipped.
gdb/testsuite/ChangeLog:
2017-10-13 Pedro Alves <palves@redhat.com>
* lib/selftest-support.exp (selftest_setup): Extend comments, and
also skip on stub-like targets.
Currently, with --target_board=native-extended-gdbserver, we get:
Running .../src/gdb/testsuite/gdb.base/find-unmapped.exp ...
FAIL: gdb.base/find-unmapped.exp: find global_var_0, global_var_2, 0xff
FAIL: gdb.base/find-unmapped.exp: find global_var_1, global_var_2, 0xff
FAIL: gdb.base/find-unmapped.exp: find global_var_2, (global_var_2 + 16), 0xff
This commit makes the test pass there, and also enables in on
--target_board=native-gdbserver, and other remote targets.
I've filed PR gdb/22293 to track the missing-warning problem.

Nowadays, we have six tic6x expedite registers, which are duplicated.
tic6x-c64xp-expedite = A15,PC
tic6x-c64x-expedite = A15,PC
tic6x-c62x-expedite = A15,PC
tic6x-c64xp-linux-expedite = A15,PC
tic6x-c64x-linux-expedite = A15,PC
tic6x-c62x-linux-expedite = A15,PC
in features/Makefile, we have
echo "expedite:$(if $($*-expedite),$($*-expedite),$($(firstword $(subst -, ,$(notdir $*)))-expedite))" \
>> $(outdir)/$*.tmp
which means for a given bar/foo-baz.xml, we'll look for either
bar/foo-baz-expedite or foo-expedite. We can define only one generic
expedite register for all different ti6cx and s390x target descriptions.
Actually, we've done that for x86 target descriptions.
Re-run 'make GDB=/path/build/gdb all' to regenerate regformats/*.dat files,
and they are not changed.

A number of targets need dynamic relocs in PIEs for reasons other than
relocating thread variables. The PR is about text relocations, and,
reading between the lines, unnecessary dynamic tprel relocations.
Change the test to check for those conditions rather than no dynamic
relocations

* testsuite/ld-elf/tls.exp: Link with -z text.
* testsuite/ld-elf/pr22263-1.rd: Test for tprel relocs.
This changes objfiles to use new and delete rather than xmalloc and
free. Simon noticed that it uses a non-POD and so shouldn't be
allocated with XCNEW; and I wanted to be able to use another non-POD as
a member; this patch is the result.
Regression tested by the buildbot.

With --target_board=native-extended-gdbserver, we get:
Running .../src/gdb/testsuite/gdb.base/term.exp ...

No saved terminal information.
Fix it by running the test everywhere, and expecting different output
on non-native targets.

This testcase works fine with gdbserver nowadays. So remove the

1. Otherwise, when we make native-gdbserver board no longer is_remote,
we get:
Running .../src/gdb/testsuite/gdb.base/corefile.exp ...
ERROR: tcl error sourcing .../src/gdb/testsuite/gdb.base/corefile.exp.
ERROR: gdbserver does not support attach 9327 without extended-remote
while executing
"error "gdbserver does not support $command without extended-remote""
That's fixed by using can_spawn_for_attach instead.
2. The gdb_protocol check fixes this current problem with
--target_board=extended-remote-gdbserver:
Running .../src/gdb/testsuite/gdb.base/corefile.exp ...
FAIL: gdb.base/corefile.exp: run: with core
FAIL: gdb.base/corefile.exp: run: core file is cleared

FAIL: gdb.base/corefile.exp: attach: core file is cleared
gdb.log:
(...)
attach 10859
Don't know how to attach. Try "help target".
(...)
The fix for #2 alone would fix#1 too, but can_spawn_for_attach
expresses the requirement directly, so I still left it there.
gdb/testsuite/ChangeLog:
2017-10-13 Pedro Alves <palves@redhat.com>

is set.

this test would stop running there.
