Tom Tromey	0d12e84cfc	Don't include gdbarch.h from defs.h ... I touched symtab.h and was surprised to see how many files were rebuilt. I looked into it a bit, and found that defs.h includes gdbarch.h, which in turn includes many things. gdbarch.h is only needed by a minority ofthe files in gdb, so this patch removes the include from defs.h and updates the fallout. I did "wc -l" on the files in build/gdb/.deps; this patch reduces the line count from 139935 to 137030; so there are definitely future build-time savings here. Note that while I configured with --enable-targets=all, it's possible that some *-nat.c file needs an update. I could not test all of these. The buildbot caught a few problems along these lines. gdb/ChangeLog 2019-07-10 Tom Tromey <tom@tromey.com> * defs.h: Don't include gdbarch.h. * aarch64-ravenscar-thread.c, aarch64-tdep.c, alpha-bsd-tdep.h, alpha-linux-tdep.c, alpha-mdebug-tdep.c, arch-utils.h, arm-tdep.h, ax-general.c, btrace.c, buildsym-legacy.c, buildsym.h, c-lang.c, cli/cli-decode.h, cli/cli-dump.c, cli/cli-script.h, cli/cli-style.h, coff-pe-read.h, compile/compile-c-support.c, compile/compile-cplus.h, compile/compile-loc2c.c, corefile.c, cp-valprint.c, cris-linux-tdep.c, ctf.c, d-lang.c, d-namespace.c, dcache.c, dicos-tdep.c, dictionary.c, disasm-selftests.c, dummy-frame.c, dummy-frame.h, dwarf2-frame-tailcall.c, dwarf2expr.c, expression.h, f-lang.c, frame-base.c, frame-unwind.c, frv-linux-tdep.c, gdbarch-selftests.c, gdbtypes.h, go-lang.c, hppa-nbsd-tdep.c, hppa-obsd-tdep.c, i386-dicos-tdep.c, i386-tdep.h, ia64-vms-tdep.c, interps.h, language.c, linux-record.c, location.h, m2-lang.c, m32r-linux-tdep.c, mem-break.c, memattr.c, mn10300-linux-tdep.c, nios2-linux-tdep.c, objfiles.h, opencl-lang.c, or1k-linux-tdep.c, p-lang.c, parser-defs.h, ppc-tdep.h, probe.h, python/py-record-btrace.c, record-btrace.c, record.h, regcache-dump.c, regcache.h, riscv-fbsd-tdep.c, riscv-linux-tdep.c, rust-exp.y, sh-linux-tdep.c, sh-nbsd-tdep.c, source-cache.c, sparc-nbsd-tdep.c, sparc-obsd-tdep.c, sparc-ravenscar-thread.c, sparc64-fbsd-tdep.c, std-regs.c, target-descriptions.h, target-float.c, tic6x-linux-tdep.c, tilegx-linux-tdep.c, top.c, tracefile.c, trad-frame.c, type-stack.h, ui-style.c, utils.c, utils.h, valarith.c, valprint.c, varobj.c, x86-tdep.c, xml-support.h, xtensa-linux-tdep.c, cli/cli-cmds.h: Update. * s390-linux-nat.c, procfs.c, inf-ptrace.c: Likewise.	2019-07-10 14:53:53 -06:00
Tom Tromey	268a13a5a3	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. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

Pedro Alves	8b88a78e63	target_stack -> current_top_target() throughout ... The recent C++ification of target_ops replaced references to the old "current_target" squashed target throughout with references to a "target_stack" pointer. I had picked the "target_stack" name very early in the multi-target work, and managed to stick with it, even though it's a bit of a misnomer, since it isn't really a "target stack" object, but a pointer into the current top target in the stack. As I'm splitting more pieces off of the multi-target branch, I've come to think that it's better to rename it now. A following patch will introduce a new class to represent a target stack, and "target_stack" would be _its_ ideal name. (In the branch, the class is called a_target_stack to work around the clash.) Thus this commit renames target_stack to current_top_target and replaces all references throughout. Also, while at it, current_top_target is made a function instead of a pointer, to make it possible to change its internal implementation without leaking implementation details out. In a couple patches, the implementation of the function will change to refer to a target stack object, and then further down the multi-target work, it'll change again to find the right target stack for the current inferior. gdb/ChangeLog: 2018-06-07 Pedro Alves <palves@redhat.com> * target.h (target_stack): Delete.

Pedro Alves	451953fa44	Eliminate the 'the_core_target' global ... (previously called 'core_target', but since renamed because 'core_target' is the name of the target_ops class now.) This eliminates the "the_core_target" global, as preparation for being able to have more than one core loaded. When we get there, we will instantiate one core_target object per core instead. Essentially, this replaces the reference to the_core_target in core_file_command by a reference to core_bfd, which is per program_space. Currently, core_file_command calls 'the_core_target->detach()' even if the core target is not open and pushed on the target stack. If it is indeed not open, then the practical effect is that core_target::detach() prints "No core file now.". That is preserved by printing that directly from within core_file_command if not debugging a core. gdb/ChangeLog: 2018-05-11 Pedro Alves <palves@redhat.com> * corefile.c (core_file_command): Move to corelow.c. * corelow.c (the_core_target): Delete.

Pedro Alves	d9f719f1ad	target factories, target open and multiple instances of targets ... Currently, to open a target, with "target TARGET_NAME", GDB finds the target_ops instance with "TARGET_NAME" as short name, and then calls its target_ops::open virtual method. In reality, there's no actual target/name lookup, a pointer to the target_ops object was associated with the "target TARGET_NAME" command at add_target time (when GDB is initialized), as the command's context. This creates a chicken and egg situation. Consider the case of wanting to open multiple remote connections. We want to be able to have one remote target_ops instance per connection, but, if we're not connected yet, so we don't yet have an instance to call target->open() on... This patch fixes this by separating out common info about a target_ops to a separate structure (shortname, longname, doc), and changing the add_target routine to take a reference to such an object instead of a pointer to a target_ops, and a pointer to a factory function that is responsible to open an instance of the corresponding target when the user types "target TARGET_NAME". -extern void add_target (struct target_ops *); +extern void add_target (const target_info &info, target_open_ftype *func); I.e. this factory function replaces the target_ops::open virtual method. For static/singleton targets, nothing changes, the target_open_ftype function pushes the global target_ops instance on the target stack. At target_close time, the connection is tor down, but the global target_ops object remains live. However, targets that support being open multiple times will make their target_open_ftype routine allocate a new target_ops instance on the heap [e.g., new remote_target()], and push that on the stack. At target_close time, the new object is destroyed (by the target_ops::close virtual method). Both the core target and the remote targets will support being open multiple times (others could/should too, but those were my stopping point), but not in this patch yet. We need to get rid of more globals first before that'd be useful. Native targets are somewhat special, given find_default_run_target & friends. Those routines also expect to return a target_ops pointer, even before we've open the target. However, we'll never need more than one instance of the native target, so we can assume/require that native targets are global/simpletons, and have the backends register a pointer to the native target_ops. Since all native targets inherit inf_child_target, we can centralize that registration. See add_inf_child_target, get_native_target/set_native_target and find_default_run_target. gdb/ChangeLog: 2018-05-02 Pedro Alves <palves@redhat.com> * aarch64-fbsd-nat.c (_initialize_aarch64_fbsd_nat): Use add_inf_child_target. * aarch64-linux-nat.c (_initialize_aarch64_linux_nat): Use add_inf_child_target. * aix-thread.c (aix_thread_target_info): New.

Pedro Alves	f6ac5f3d63	Convert struct target_ops to C++ ... I.e., use C++ virtual methods and inheritance instead of tables of function pointers. Unfortunately, there's no way to do a smooth transition. ALL native targets in the tree must be converted at the same time. I've tested all I could with cross compilers and with help from GCC compile farm, but naturally I haven't been able to test many of the ports. Still, I made a best effort to port everything over, and while I expect some build problems due to typos and such, which should be trivial to fix, I don't expect any design problems. * Implementation notes: - The flattened current_target is gone. References to current_target or current_target.beneath are replaced with references to target_stack (the top of the stack) directly. - To keep "set debug target" working, this adds a new debug_stratum layer that sits on top of the stack, prints the debug, and delegates to the target beneath. In addition, this makes the shortname and longname properties of target_ops be virtual methods instead of data fields, and makes the debug target defer those to the target beneath. This is so that debug code sprinkled around that does "if (debugtarget) ..." can transparently print the name of the target beneath. A patch later in the series actually splits out the shortname/longname methods to a separate structure, but I preferred to keep that chance separate as it is associated with changing a bit the design of how targets are registered and open. - Since you can't check whether a C++ virtual method is overridden, the old method of checking whether a target_ops implements a method by comparing the function pointer must be replaced with something else. Some cases are fixed by adding a parallel "can_do_foo" target_ops methods. E.g.,: + for (t = target_stack; t != NULL; t = t->beneath) { - if (t->to_create_inferior != NULL) + if (t->can_create_inferior ()) break; } Others are fixed by changing void return type to bool or int return type, and have the default implementation return false or -1, to indicate lack of support. - make-target-delegates was adjusted to generate C++ classes and methods. It needed tweaks to grok "virtual" in front of the target method name, and for the fact that methods are no longer function pointers. (In particular, the current code parsing the return type was simple because it could simply parse up until the '(' in '(*to_foo)'. It now generates a couple C++ classes that inherit target_ops: dummy_target and debug_target. Since we need to generate the class declarations as well, i.e., we need to emit methods twice, we now generate the code in two passes. - The core_target global is renamed to avoid conflict with the "core_target" class. - ctf/tfile targets init_tracefile_ops is replaced by a base class that is inherited by both ctf and tfile. - bsd-uthread The bsd_uthread_ops_hack hack is gone. It's not needed because nothing was extending a target created by bsd_uthread_target. - remote/extended-remote targets This is a first pass, just enough to C++ify target_ops. A later pass will convert more free functions to methods, and make remote_state be truly per remote instance, allowing multiple simultaneous instances of remote targets. - inf-child/"native" is converted to an actual base class (inf_child_target), that is inherited by all native targets. - GNU/Linux The old weird double-target linux_ops mechanism in linux-nat.c, is gone, replaced by adding a few virtual methods to linux-nat.h's target_ops, called low_XXX, that the concrete linux-nat implementations override. Sort of like gdbserver's linux_target_ops, but simpler, for requiring only one target_ops-like hierarchy, which spares implementing the same method twice when we need to forward the method to a low implementation. The low target simply reimplements the target_ops method directly in that case. There are a few remaining linux-nat.c hooks that would be better converted to low_ methods like above too. E.g.: linux_nat_set_new_thread (t, x86_linux_new_thread); linux_nat_set_new_fork (t, x86_linux_new_fork); linux_nat_set_forget_process That'll be done in a follow up patch. - We can no longer use functions like x86_use_watchpoints to install custom methods on an arbitrary base target. The patch replaces instances of such a pattern with template mixins. For example memory_breakpoint_target defined in target.h, or x86_nat_target in x86-nat.h. - linux_trad_target, MIPS and Alpha GNU/Linux The code in the new linux-nat-trad.h/c files which was split off of inf-ptrace.h/c recently, is converted to a C++ base class, and used by the MIPS and Alpha GNU/Linux ports. - BSD targets The $architecture x NetBSD/OpenBSD/FreeBSD support matrix complicates things a bit. There's common BSD target code, and there's common architecture-specific code shared between the different BSDs. Currently, all that is stiched together to form a final target, via the i386bsd_target, x86bsd_target, fbsd_nat_add_target functions etc. This introduces new fbsd_nat_target, obsd_nat_target and nbsd_nat_target classes that serve as base/prototype target for the corresponding BSD variant. And introduces generic i386/AMD64 BSD targets, to be used as template mixin to build a final target. Similarly, a generic SPARC target is added, used by both BSD and Linux ports. - bsd_kvm_add_target, BSD libkvm target I considered making bsd_kvm_supply_pcb a virtual method, and then have each port inherit bsd_kvm_target and override that method, but that was resulting in lots of unjustified churn, so I left the function pointer mechanism alone. gdb/ChangeLog: 2018-05-02 Pedro Alves <palves@redhat.com> John Baldwin <jhb@freebsd.org> * target.h (enum strata) <debug_stratum>: New.

Tom Tromey	76727919ce	Convert observers to C++ ... This converts observers from using a special source-generating script to be plain C++. This version of the patch takes advantage of C++11 by using std::function and variadic templates; incorporates Pedro's patches; and renames the header file to "observable.h" (this change eliminates the need for a clean rebuild).

Simon Marchi	6e1e1966ba	Pass inferior down to target_detach and to_detach ... The to_detach target_ops method implementations are currently expected to work on current_inferior/inferior_ptid. In order to make things more explicit, and remove some "shadow" parameter passing through globals, this patch adds an "inferior" parameter to to_detach. Implementations will be expected to use this instead of relying on the global. However, to keep things simple, this patch only does the minimum that is necessary to add the parameter. The following patch gives an example of how one such implementation would be adapted. If the approach is deemed good, we can then look into adapting more implementations. Until then, they'll continue to work as they do currently. gdb/ChangeLog: * target.h (struct target_ops) <to_detach>: Add inferior parameter. (target_detach): Likewise. * target.c (dispose_inferior): Pass inferior down. (target_detach): Pass inferior down.

Simon Marchi	6bd6f3b656	Remove args from target detach ... I was looking into adding a parameter to target_detach, and was wondering what the args parameter was. It seems like in the distant past, it was possible to specify a signal number when detaching. That signal was injected in the process before it was detached. There is an example of code handling this in linux_nat_detach. With today's GDB, I can't get this to work. Doing "detach 15" (15 == SIGTERM) doesn't work, because detach is a prefix command and doesn't recognize the sub-command 15. Doing "detach inferiors 15" doesn't work because it expects a list of inferior id to detach. Therefore, I don't think there's a way of invoking detach_command with a non-NULL args. I also didn't find any documentation related to this feature. I assume that this feature stopped working when detach was made a prefix command, which is in f73adfeb8b (sorry, there's no commit title) from 2006. Given that this feature was broken for such a long time and we haven't heard anything (AFAIK, I did not find any related bug), I think it's safe to remove it, as well as the args parameter to target_detach. If someone wants to re-introduce it, I would suggest rethinking the user interface, and in particular would suggest using signal name instead of numbers. I tried to fix all the impacted code, but I might have forgotten some spots. It shouldn't be hard to fix if that's the case. I also couldn't build-test everything I changed, especially the nto and solaris stuff. gdb/ChangeLog: * target.h (struct target_ops) <to_detach>: Remove args parameter.

Pedro Alves	eb3ff9a551	Introduce class completion_tracker & rewrite completion<->readline interaction ... This patch reworks the whole completion machinery, and prepares it for later enhancements. Adds a new "completion_tracker" class that is meant to hold everything about the state of the current completion operation. This class now has the responsibility of tracking the list of completion matches, and checking whether the max completions limit has been reached. You can look at this as this patch starting out by C++fying the existing "completion_tracker" in symtab.c (it's just an htab_t typedef currently), moving it to completer.h/c, and then making it a class/generalizing/enhancing it. Unlike with the current tracking, completion_tracker now checks whether the limit has been reached on each completion match list insertion. This both simplifies the max-completions handling code (maybe_add_completion_enum is gone, for example), and is a prerequisite for follow up patches. The current completion_tracker is only used for symbol completions, and the symbol code gets at the current instance via globals. This patch cleans that up by adding a completion_tracker reference to the signature of the completion functions, and passing the tracker around everywhere necessary. Then, the patch changes how the completion match list is handed over to readline. Currently, we're using the rl_completion_entry_function readline entry point, and the patch switches to rl_attempted_completion_function. A following patch will want to let GDB itself decide the common completion prefix between all matches (what readline calls the "lowest common denominator"), instead of having readline compute it, and that's not possible with the rl_completion_entry_function entry point. Also, rl_attempted_completion_function lets GDB hand over the match list to readline as an array in one go instead of passing down matches one by one, so from that angle it's a nicer entry point anyway. Lastly, the patch catches exceptions around the readline entry points, because we can't let C++ exceptions cross readline. We handle that in the readline input entry point, but the completion entry point isn't guarded, so GDB can abort if completion throws. E.g., in current master: (gdb) b -function "fun<tab> terminate called after throwing an instance of 'gdb_exception_RETURN_MASK_ERROR' Aborted (core dumped) This patch fixes that. This will be exercised in the new tests added later on in the series. gdb/ChangeLog: 2017-07-17 Pedro Alves <palves@redhat.com> * ada-lang.c (symbol_completion_match): Adjust comments.

Sergio Durigan Junior	2090129c36	Share fork_inferior et al with gdbserver ... This is the most important (and the biggest, sorry) patch of the series. It moves fork_inferior from gdb/fork-child.c to nat/fork-inferior.c and makes all the necessary adjustments to both GDB and gdbserver to make sure everything works OK. There is no "most important change" with this patch; all changes are made in a progressive way, making sure that gdbserver had the necessary features while not breaking GDB at the same time. I decided to go ahead and implement a partial support for starting the inferior with a shell on gdbserver, although the full feature comes in the next patch. The user won't have the option to disable the startup-with-shell, and also won't be able to change which shell gdbserver will use (other than setting the $SHELL environment variable, that is). Everything is working as expected, and no regressions were present during the tests. gdb/ChangeLog: 2017-06-07 Sergio Durigan Junior <sergiodj@redhat.com> Pedro Alves <palves@redhat.com> * Makefile.in (HFILES_NO_SRCDIR): Add "common/common-inferior.h" and "nat/fork-inferior.h". * common/common-inferior.h: New file, with contents from "gdb/inferior.h". * commom/common-utils.c: Include "common-utils.h".

Pedro Alves	d09f2c3fc1	target_read_memory&co: no longer return target_xfer_status ... Years ago, these functions used to return errno/EIO. Later, through a series of changes that intended to remove native/remote differences, they ended up returning a target_xfer_status in disguise. Unlike target_xfer_partial&co, the point of target_read_memory&co is to either fully succeed or fail. On error, they always return TARGET_XFER_E_IO. So there's no real point in casting the return of target_read_memory to a target_xfer_status to pass it to memory_error. Instead, it results in clearer code to simply decouple target_read_memory&co's return from target_xfer_status. This fixes build errors like this in C++ mode: ../../src/gdb/corefile.c: In function ‘void read_stack(CORE_ADDR, gdb_byte*, ssize_t)’: ../../src/gdb/corefile.c:276:34: error: invalid conversion from ‘int’ to ‘target_xfer_status’ [-fpermissive] memory_error (status, memaddr); ^ ../../src/gdb/corefile.c:216:1: error: initializing argument 1 of ‘void memory_error(target_xfer_status, CORE_ADDR)’ [-fpermissive] gdb/ChangeLog: 2015-10-27 Pedro Alves <palves@redhat.com> * alpha-tdep.c (alpha_read_insn): Always pass TARGET_XFER_E_IO to memory_error.

Simon Marchi	224c3ddb89	Add casts to memory allocation related calls ... Most allocation functions (if not all) return a void* pointing to the allocated memory. In C++, we need to add an explicit cast when assigning the result to a pointer to another type (which is the case more often than not). The content of this patch is taken from Pedro's branch, from commit "(mostly) auto-generated patch to insert casts needed for C++". I validated that the changes make sense and manually reflowed the code to make it respect the coding style. I also found multiple places where I could use XNEW/XNEWVEC/XRESIZEVEC/etc. Thanks a lot to whoever did that automated script to insert casts, doing it completely by hand would have taken a ridiculous amount of time. Only files built on x86 with --enable-targets=all are modified. This means that all other -nat.c files are untouched and will have to be dealt with later by using appropiate compilers. Or maybe we can try to build them with a regular g++ just to know where to add casts, I don't know. I built-tested this with --enable-targets=all and reg-tested. Here's the changelog entry, which was not too bad to make despite the size, thanks to David Malcom's script. I fixed some bits by hand, but there might be some wrong parts left (hopefully not). gdb/ChangeLog: * aarch64-linux-tdep.c (aarch64_stap_parse_special_token): Add cast to allocation result assignment. * ada-exp.y (write_object_renaming): Likewise.

Simon Marchi	8d7493201c	Replace some xmalloc-family functions with XNEW-family ones ... This patch is part of the make-gdb-buildable-in-C++ effort. The idea is to change some calls to the xmalloc family of functions to calls to the equivalents in the XNEW family. This avoids adding an explicit cast, so it keeps the code a bit more readable. Some of them also map relatively well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be possible to do scripted replacements if needed. I only changed calls that were obviously allocating memory for one or multiple "objects". Allocation of variable sizes (such as strings or buffer handling) will be for later (and won't use XNEW). - xmalloc (sizeof (struct foo)) -> XNEW (struct foo) - xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num) - xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo) - xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num) - xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num) - obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo) - obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num) - alloca (sizeof (struct foo)) -> XALLOCA (struct foo) - alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num) Some instances of xmalloc followed by memset to zero the buffer were replaced by XCNEW or XCNEWVEC. I regtested on x86-64, Ubuntu 14.04, but the patch touches many architecture-specific files. For those I'll have to rely on the buildbot or people complaining that I broke their gdb. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_add_process): Likewise. * aarch64-tdep.c (aarch64_gdbarch_init): Likewise. * ada-exp.y (write_ambiguous_var): Likewise. * ada-lang.c (resolve_subexp): Likewise.

Yao Qi	bc113b4e3e	Rename TARGET_XFER_E_UNAVAILABLE to TARGET_XFER_UNAVAILABLE ... Nowadays, TARGET_XFER_E_UNAVAILABLE isn't regarded as an error in to_xfer_partial interface, so _E_ looks odd.

Yao Qi	9b409511d0	Return target_xfer_status in to_xfer_partial ... This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0". This patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface. The interface still behaves as before. gdb: 2014-02-11 Yao Qi <yao@codesourcery.com> * target.h (enum target_xfer_error): Rename to ... (enum target_xfer_status): ... it. New. All users updated.

Yao Qi	0865b04a4d	Use target_read_code in skip_prologue (i386) ... GDB is able to cache memory accesses requested in target_read_code, so target_read_code is more efficient than general target_read_memory. This patch uses target_read_code and its variants to read target memory in the functions related to i386_skip_prologue. It improves the performance when doing 'b foo' (foo is a function) in remote debugging. Nowadays, when we set a breakpoint on function f1, GDB will fetch the code in f1 to determine the start of the function body (say skip the prologue), it requests read from target many times. With this patch applied, the number of RSP 'm' packets are reduced. gdb: 2013-12-10 Yao Qi <yao@codesourcery.com> * corefile.c (read_code): New function. (read_code_integer): New function.

Pedro Alves	578d3588ee	Stop using errno values around target_xfer interfaces and memory errors. ... target_read_memory & friends build on top of target_read (thus on top of the target_xfer machinery), but turn all errors to EIO, an errno value. I think we'd better convert all these to return a target_xfer_error too, like target_xfer_partial in a previous patch. The patch starts by doing that. (The patch does not add a enum target_xfer_error value for '0'/no error, and likewise does not change the return type of several of these functions to enum target_xfer_error, because different functions return '0' with different semantics.) I audited the tree for memory_error calls, EIO checks, places where GDB hardcodes 'errno = EIO', and also for strerror calls. What I found is that nowadays there's really no need to handle random errno values, other than the EIOs gdb itself hardcodes. No doubt errno values would appear in common code back in the day when target_xfer_memory was the main interface to access memory, but nowadays, any errno value that deprecated interface could return is just absorved by default_xfer_partial: else if (xfered == 0 && errno == 0) /* "deprecated_xfer_memory" uses 0, cross checked against ERRNO as one indication of an error. */ return 0; else return -1; There are two places in the code that check for EIO and print "out of bounds", and defer to strerror for other errors. That's c-lang.c:c_get_string, and valprint.c.:val_print_string. AFAICT, the strerror branch can never be reached nowadays, as the only error possible to get at those points is EIO, given that it's GDB itself that set that errno value (in target_read_memory, etc.). breakpoint.c:insert_bp_location always prints the error val as if an errno, returned by target_insert_breakpoint, with strerr. Now the error here is either always EIO for mem-break.c targets (again hardcoded by the target_read_memory/target_write_memory functions), so this always prints "Input/output error" or similar (depending on host), or, for remote targets (and probably others), this gem: Error accessing memory address 0x80200400: Unknown error -1. This patch makes these 3 places print the exact same error memory_error prints. This changes output, but I think this is better, for making memory error output consistent with other commands, and, it means we have a central place to tweak for memory errors. E.g., this changes: Cannot insert breakpoint 1. Error accessing memory address 0x5fc660: Input/output error. to: Cannot insert breakpoint 1. Cannot access memory at address 0x5fc660 Which I find pretty much acceptable. Surprisingly, only py-prettyprint.exp had a regression, for needing an adjustment. I also grepped the testsuite for the old errors, and found no other hits. Now that errno values aren't used anywhere in any of these memory access related routines, I made memory_error itself take a target_xfer_error instead of an errno. The new target_xfer_memory_error function added recently is no longer necessary, and is thus removed.

However, the actual output is: (gdb) frame #0 0x0000000000400540 in foo (i=0, i@entry=2, j=2, j@entry=<error reading variable: Cannot access memory at address 0x6009e8>) The error is thrown here: #0 throw_it (reason=RETURN_ERROR, error=MEMORY_ERROR, fmt=0x8cd550 "Cannot access memory at address %s", ap=0x7fffffffc8e8) at ../../src/gdb/exceptions.c:373 #1 0x00000000005e2f9c in throw_error (error=MEMORY_ERROR, fmt=0x8cd550 "Cannot access memory at address %s") at ../../src/gdb/exceptions.c:422 #2 0x0000000000673a5f in memory_error (status=5, memaddr=6293992) at ../../src/gdb/corefile.c:204 #3 0x0000000000673aea in read_memory (memaddr=6293992, myaddr=0x7fffffffca60 "\200\316\377\377\377\177", len=4) at ../../src/gdb/corefile.c:223 #4 0x00000000006784d1 in dwarf_expr_read_mem (baton=0x7fffffffcd50, buf=0x7fffffffca60 "\200\316\377\377\377\177", addr=6293992, len=4) at ../../src/gdb/dwarf2loc.c:334 #5 0x000000000067645e in execute_stack_op (ctx=0x1409480, op_ptr=0x7fffffffce87 "\237<\005@", op_end=0x7fffffffce88 "<\005@") at ../../src/gdb/dwarf2expr.c:1045 #6 0x0000000000674e29 in dwarf_expr_eval (ctx=0x1409480, addr=0x7fffffffce80 "\003\350\t`", len=8) at ../../src/gdb/dwarf2expr.c:364 #7 0x000000000067c5b2 in dwarf2_evaluate_loc_desc_full (type=0x10876d0, frame=0xd8ecc0, data=0x7fffffffce80 "\003\350\t`", size=8, per_cu=0xf24c40, byte_offset=0) at ../../src/gdb/dwarf2loc.c:2236 #8 0x000000000067cc65 in dwarf2_evaluate_loc_desc (type=0x10876d0, frame=0xd8ecc0, data=0x7fffffffce80 "\003\350\t`", size=8, per_cu=0xf24c40) at ../../src/gdb/dwarf2loc.c:2407 #9 0x000000000067a5d4 in dwarf_entry_parameter_to_value (parameter=0x13a7960, deref_size=18446744073709551615, type=0x10876d0, caller_frame=0xd8ecc0, per_cu=0xf24c40) at ../../src/gdb/dwarf2loc.c:1160 #10 0x000000000067a962 in value_of_dwarf_reg_entry (type=0x10876d0, frame=0xd8de70, kind=CALL_SITE_PARAMETER_DWARF_REG, kind_u=...) at ../../src/gdb/dwarf2loc.c:1310 #11 0x000000000067aaca in value_of_dwarf_block_entry (type=0x10876d0, frame=0xd8de70, block=0xf1c2d4 "Q", block_len=1) at ../../src/gdb/dwarf2loc.c:1363 #12 0x000000000067e7c9 in locexpr_read_variable_at_entry (symbol=0x13a7540, frame=0xd8de70) at ../../src/gdb/dwarf2loc.c:3326 #13 0x00000000005daab6 in read_frame_arg (sym=0x13a7540, frame=0xd8de70, argp=0x7fffffffd0e0, entryargp=0x7fffffffd100) at ../../src/gdb/stack.c:362 #14 0x00000000005db384 in print_frame_args (func=0x13a7470, frame=0xd8de70, num=-1, stream=0xea3890) at ../../src/gdb/stack.c:669 #15 0x00000000005dc338 in print_frame (frame=0xd8de70, print_level=1, print_what=SRC_AND_LOC, print_args=1, sal=...) at ../../src/gdb/stack.c:1199 #16 0x00000000005db8ee in print_frame_info (frame=0xd8de70, print_level=1, print_what=SRC_AND_LOC, print_args=1) at ../../src/gdb/stack.c:851 #17 0x00000000005da2bb in print_stack_frame (frame=0xd8de70, print_level=1, print_what=SRC_AND_LOC) at ../../src/gdb/stack.c:169 #18 0x00000000005de236 in frame_command (level_exp=0x0, from_tty=1) at ../../src/gdb/stack.c:2265 dwarf2_evaluate_loc_desc_full (frame #7) knows to handle NOT_AVAILABLE_ERROR errors, but read_memory always throws a generic error. Presently, only the value machinery knows to handle unavailable memory. We need to push the awareness down to the target_xfer layer, making it return a finer grained error indication. We can only return a generic -1 nowadays, which leaves the upper layers with no clue on why the xfer failed. Use target_xfer_partial directly, rather than propagating the error through target_read_memory so as to get a better address to display in the error message. (target_read_memory & friends build on top of target_read (thus the target_xfer machinery), but turn all errors to EIO, an errno value. I think this is a mistake, and we'd better convert all these to return a target_xfer_error too, but that can be done separately. I looked around a bit over memory_error calls, and the need to handle random errno values, other than the EIOs gdb itself hardcodes, probably comes (only) from deprecated_xfer_memory, which uses errno for error indication, but I didn't look exhaustively. We should really get rid of deprecated_xfer_memory and of passing down errno values as error indication in target_read & friends methods). Tested on x86_64 Fedora 17, native and gdbserver. Fixes the test in the PR, which will be added to the testsuite later. gdb/ 2013-08-22 Pedro Alves <palves@redhat.com> PR gdb/15871 * corefile.c (target_xfer_memory_error): New function.

Pedro Alves	6f937416b9	Constify strings in tracepoint.c, lookup_cmd and the completers. ... This is sort of a continuation of Keith's parse_exp_1 constification patch. It started out by undoing these bits: @@ -754,9 +754,12 @@ validate_actionline (char **line, struct tmp_p = p; for (loc = t->base.loc; loc; loc = loc->next) { - p = tmp_p; - exp = parse_exp_1 (&p, loc->address, + const char *q; + + q = tmp_p; + exp = parse_exp_1 (&q, loc->address, block_for_pc (loc->address), 1); + p = (char *) q; and progressively making more things const upwards, fixing fallout, rinse repeat, until GDB built again (--enable-targets=all). That ended up constifying lookup_cmd/add_cmd and (lots of) friends, and the completers. I didn't try to constify the command hooks themselves, because I know upfront there are commands that write to the command string argument, and I think I managed to stop at a nice non-hacky split point already. I think the only non-really-super-obvious changes are tracepoint.c:validate_actionline, and tracepoint.c:trace_dump_actions. The rest is just mostly about 'char *' => 'const char *', 'char **'=> 'const char **', and the occasional (e.g., deprecated_cmd_warning) case of 'char **'=> 'const char *', where/when I noticed that nothing actually cares about the pointer to pointer output.
