Tom Tromey	bf31fd38f0	Move gdb obstack code to gdbsupport This moves the gdb-specific obstack code -- both extensions like obconcat and obstack_strdup, and things like auto_obstack -- to gdbsupport.	4 years ago
Tom Tromey	7904e9613e	Move gdb_argv to gdbsupport This moves the gdb_argv class to a new header in gdbsupport.	6 years ago
Tom Tromey	5947982f1d	Simplify event_location_probe event_location_probe currently stores two strings, but really only needs one. This patch simplifies it and removes some unnecessary copies as well.	4 years ago
Tom Tromey	85e428a69f	Use std::string in event_location This changes event_location to use std::string, removing some manual memory management, and an unnecessary string copy.	4 years ago
Tom Tromey	2b0c285ea5	Split event_location into subclasses event_location uses the old C-style discriminated union approach. However, it's better to use subclassing, as this makes the code clearer and removes some chances for error. This also enables future cleanups to avoid manual memory management and copies.	4 years ago
Tom Tromey	49a9cf56ff	Remove EL_* macros from location.c This patch removes the old-style EL_* macros from location.c. This cleans up the code by itself, IMO, but also enables further cleanups in subsequent patches.	4 years ago
Tom Tromey	7910e2dee3	Boolify explicit_to_string_internal This changes explicit_to_string_internal to use 'bool' rather than 'int'.	4 years ago
Tom Tromey	dab863ef40	Remove a use of xfree in location.c This small cleanup removes a use of xfree from location.c, by switching to unique_xmalloc_ptr. One function is only used in location.c, so it is made static. And, another function is changed to avoid a copy.	4 years ago
Simon Marchi	e53c95d40b	gdb: use ptid_t::to_string instead of target_pid_to_str in debug statements Same idea as `0fab795564` ("gdb: use ptid_t::to_string in infrun debug messages"), but throughout GDB. Change-Id: I62ba36eaef29935316d7187b9b13d7b88491acc1	4 years ago
Andrew Burgess	cced7cacec	gdb: preserve `\|` in connection details string Consider this GDB session: $ gdb -q (gdb) target remote \| gdbserver - ~/tmp/hello.x Remote debugging using \| gdbserver - ~/tmp/hello.x ... snip ... (gdb) info connections Num What Description * 1 remote gdbserver - ~/tmp/hello.x Remote target using gdb-specific protocol (gdb) python conn = gdb.selected_inferior().connection (gdb) python print(conn.details) gdbserver - ~/tmp/hello.x (gdb) I think there are two things wrong here, first in the "What" column of the 'info connections' output, I think the text should be: remote \| gdbserver - ~/tmp/hello.x to correctly show the user how the connection was established. And in a similar fashion, I think that the `details` string of the gdb.TargetConnection object should be: \| gdbserver - ~/tmp/hello.x This commit makes this change. Currently the '\|' is detected and removed in gdb/serial.c. The string passed to the pipe_ops structure (from gdb/ser-pipe.c), doesn't then, contain the `\|`, this is instead implied by the fact that it is a pipes based implementation of the serial_ops interface. After this commit we still detect the `\|` in gdb/serial.c, but we now store the full string (including the `\|`) in the serial::name member variable. For pipe based serial connections, this name is only used for displaying the two fields I mention above, and in pipe_open (from gdb/ser-pipe.c), and in pipe_open, we now know to skip over the `\|`. The benefit I see from this change is that GDB's output now more accurately reflects the commands used to start a target, thus making it easier for a user to understand what is going on.	4 years ago

Alan Modra	e2c0149e8b	PR28029, debuginfod tests binutils/NEWS says of the change in --process-links semantics: If other debug section display options are also enabled (eg --debug-dump=info) then the contents of matching sections in both the main file and the separate debuginfo file will be displayed. This is because in most cases the debug section will only be present in one of the files. Implying that debug info is dumped without --process-links. Indeed that appears to be the case for readelf. This does the same for objdump. PR 28029 * objdump.c (dump_bfd): Do not exit early when !is_mainfile && !processlinks, instead just exclude non-debug output. (dump_dwarf): Add is_mainfile parameter and pass to dump_dwarf_section. (dump_dwarf_section): Only display debug sections when !is_mainfile and !process_links.	4 years ago

Alan Modra	1657026ccd	PowerPC64 DT_RELR PowerPC64 takes a more traditional approach to DT_RELR than x86. Count relative relocs in check_relocs, allocate space for them and output in the usual places but not doing so when enable_dt_relr. DT_RELR is sized in the existing ppc stub relaxation machinery, run via the linker's ldemul_after_allocation hook. DT_RELR is output in the same function that writes ppc stubs, run via ldemul_finish.

Jan Beulich	ab31da6aff	x86: adjust struct instr_info field types Now that this lives on the stack, let's have it be a little less wasteful in terms of space. Switch boolean fields to "bool" (also when this doesn't change their size) and also limit the widths of "rex", "rex_used", "op_ad", and "op_index".

Simon Marchi	513569fbb7	gdb.dlang/demangle.exp: update expected output for _D8demangle4testFnZv Since commit `ce2d3708bc` ("Synchronize binutils libiberty sources with gcc version."), I see this failure: demangle _D8demangle4testFnZv^M demangle.test(typeof(null))^M (gdb) FAIL: gdb.dlang/demangle.exp: _D8demangle4testFnZv The commit imported the commit 0e32a5aa8bc9 ("libiberty: Add support for D `typeof(*null)' types") from the gcc repository. That commit includes an update to libiberty/testsuite/d-demangle-expected, which updates a test for the exact same mangled name: _D8demangle4testFnZv -demangle.test(none) +demangle.test(typeof(null)) I don't know anything about D, but give that the change was made by Iain Buclaw, the D language maintainer, I trust him on that. Fix our test by updating the expected output in the same way. Note: it's not really useful to have all these D demangling tests in the GDB testsuite, since there are demangling tests in libiberty. We should consider removing them, but we first need to make sure that everything that is covered in gdb/testsuite/gdb.dlang/demangle.exp is also covered in libiberty/testsuite/d-demangle-expected.

Jan Beulich	928c8d70c8	x86: consistently use scalar_mode for AVX512-FP16 scalar insns For some reason the original AVFX512F insns were not taken as a basis here, causing unnecessary divergence. While not an active issue, it is still relevant to note that OP_XMM() has special treatment of e.g. scalar_mode (marking broadcast as invalid). Such would better be consistent for all sufficiently similar insns.	4 years ago
Jan Beulich	a364447b5e	x86: record further wrong uses of EVEX.b For one EVEX.W set does not imply EVEX.b is uniformly valid. Reject it for modes which occur for insns allowing for EVEX.W to be set (noticed with VMOV{H,L}PD and VMOVDDUP, and only in AT&T mode, but not checked whether further insns would also have been impacted; I expect e.g. VCMPSD would have had the same issue). And then the present concept of broadcast makes no sense at all when the memory operand of an insn is the destination.	4 years ago
Jan Beulich	740a1e7911	x86: reduce AVX512 FP set of insns decoded through vex_w_table[] Like for AVX512-FP16, there's not that many FP insns where going through this table is easier / cheaper than using suitable macros. Utilize %XS and %XD more to eliminate a fair number of table entries. While doing this I noticed a few anomalies. Where lines get touched / moved anyway, these are being addressed right here: - vmovshdup used EXx for its 2nd operand, thus displaying seemingly valid broadcast when EVEX.b is set with a memory operand; use EXEvexXNoBcst instead just like vmovsldup already does - vmovlhps used EXx for its 3rd operand, when all sibling entries use EXq; switch to EXq there for consistency (the two differ only for memory operands)	4 years ago
Jan Beulich	2235ecb8af	x86: reduce AVX512-FP16 set of insns decoded through vex_w_table[] Like already indicated during review of the original submission, there's really only very few insns where going through this table is easier / cheaper than using suitable macros. Utilize %XH more and introduce similar %XS and %XD (which subsequently can be used for further table size reduction). While there also switch to using oappend() in 'XH' macro processing.	4 years ago

Andrew Burgess	4b74833d1a	gdb: don't use -Wmissing-prototypes with g++ This commit aims to not make use of -Wmissing-prototypes when compiling with g++. Use of -Wmissing-prototypes was added with this commit: commit `a0761e34f0` Date: Wed Mar 11 15:15:12 2020 -0400 gdb: enable -Wmissing-prototypes warning Because clang can provide helpful warnings with this flag. Unfortunately, g++ doesn't accept this flag, and will give this warning: cc1plus: warning: command line option ‘-Wmissing-prototypes’ is valid for C/ObjC but not for C++ In theory the fact that this flag is not supported should be detected by the configure check in gdbsupport/warning.m4, but for users of ccache, this check doesn't work due to a long standing ccache issue: https://github.com/ccache/ccache/issues/738 The ccache problem is that -W... options are reordered on the command line, and so -Wmissing-prototypes is seen before -Werror. Usually this doesn't matter, but the above warning (about the flag not being valid) is issued before the -Werror flag is processed, and so is not fatal. There have been two previous attempts to fix this that I'm aware of. The first is: https://sourceware.org/pipermail/gdb-patches/2021-September/182148.html In this attempt, instead of just relying on a compile to check if a flag is valid, the proposal was to both compile and link. As linking doesn't go through ccache, we don't suffer from the argument reordering problem, and the link phase will correctly fail when using -Wmissing-prototypes with g++. The configure script will then disable the use of this flag. This approach was rejected, and the suggestion was to only add the -Wmissing-prototypes flag if we are compiling with gcc. The second attempt, attempts this approach, and can be found here: https://sourceware.org/pipermail/gdb-patches/2021-November/183076.html This attempt only adds the -Wmissing-prototypes flag is the value of GCC is not 'yes'. This feels like it is doing the right thing, unfortunately, the GCC flag is really a 'is gcc like' flag, not a strict, is gcc check. As such, GCC is set to 'yes' for clang, which would mean the flag was not included for clang or gcc. The entire point of the original commit was to add this flag for clang, so clearly the second attempt is not sufficient either. In this new attempt I have added gdbsupport/compiler-type.m4, this file defines AM_GDB_COMPILER_TYPE. This macro sets the variable GDB_COMPILER_TYPE to either 'gcc', 'clang', or 'unknown'. In future the list of values might be extended to cover other compilers, if this is ever useful. I've then modified gdbsupport/warning.m4 to only add the problematic -Wmissing-prototypes flag if GDB_COMPILER_TYPE is not 'gcc'. I've tested this with both gcc and clang and see the expected results, gcc no longer attempts to use the -Wmissing-prototypes flag, while clang continues to use it. When compiling using ccache, I am no longer seeing the warning.	4 years ago
Andrew Burgess	993248f443	gdb: add some extra debug information to attach_command While working on another patch I wanted to add some extra debug information to the attach_command function. This required me to add a new function to convert the thread_info::state variable to a string. The new debug might be useful to others, and the state to string function might be useful in other locations, so I thought I'd merge it.	4 years ago
