2023-10-28gdb/gdbsupport/gdbserver: Require c++17Lancelot Six1-1/+1
This patch proposes to require a C++17 compiler to build gdb / gdbsupport / gdbserver. Before this patch, GDB required a C++11 compiler. The general policy regarding bumping C++ language requirement in GDB (as stated in [1]) is: Our general policy is to wait until the oldest compiler that supports C++NN is at least 3 years old. Rationale: We want to ensure reasonably widespread compiler availability, to lower barrier of entry to GDB contributions, and to make it easy for users to easily build new GDB on currently supported stable distributions themselves. 3 years should be sufficient for latest stable releases of distributions to include a compiler for the standard, and/or for new compilers to appear as easily installable optional packages. Requiring everyone to build a compiler first before building GDB, which would happen if we required a too-new compiler, would cause too much inconvenience. See the policy proposal and discussion [here](https://sourceware.org/ml/gdb-patches/2016-10/msg00616.html). The first GCC release which with full C++17 support is GCC-9[2], released in 2019[3], which is over 4 years ago. Clang has had C++17 support since Clang-5[4] released in 2018[5]. A discussions with many distros showed that a C++17-able compiler is always available, meaning that this no hard requirement preventing us to require it going forward.

2023-02-24Remove struct bufferTom Tromey1-3/+1
I've long wanted to remove 'struct buffer', and thanks to Simon's earlier patch, I was finally able to do so. My feeling has been that gdb already has several decent structures available for growing strings: std::string of course, but also obstack and even objalloc from BFD and dyn-string from libiberty. The previous patches in this series removed all the uses of struct buffer, so this one can remove the code and the remaining #includes.
2023-01-05gdbsupport: move libxxhash configure check to gdbsupportSimon Marchi1-0/+3
The following patch moves the fast_hash function, which uses libxxhash, to gdbsupport. Move the libxxhash configure check to gdbsupport (and transitively to gdbserver). Change-Id: I242499e50c8cd6fe9f51e6e92dc53a1b3daaa96e Approved-By: Andrew Burgess <aburgess@redhat.com>
2022-09-08gdbsupport: Fix config.status dependencyTsukasa OI1-0/+1
Commit 171fba11ab27 ("Make GDBserver abort on internal error in development mode") created a new substitution CONFIG_STATUS_DEPENDENCIES but this is used by Makefile.in (which is not regenerated by that commit). After regenerating it, it is found that CONFIG_STATUS_DEPENDENCIES value is not valid, making gdbsupport fail to build. Since the CONFIG_STATUS_DEPENDENCIES value is used in the Makefile, macro substitution must have a Makefile format but commit 171fba11ab27 used shell format "$srcdir/../bfd/development.sh". This commit fixes this issue by substituting "$srcdir" (shell format) to "$(srcdir)" (Makefile format). It preserves the dependency as Pedro intended and fixes the build problem. It also regenerates corresponding files with the maintainer mode. gdbsupport/ChangeLog: * configure.ac: Fix config.status dependency. * Makefile.in: Regenerate. * configure: Regenerate.

2022-01-13gdb: don't use -Wmissing-prototypes with g++Andrew Burgess1-2/+2
This commit aims to not make use of -Wmissing-prototypes when compiling with g++. Use of -Wmissing-prototypes was added with this commit: commit a0761e34f054767de6d6389929d27e9015fb299b 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.
2022-01-11gdbsupport: regenerate Makefile.inAndrew Burgess1-2/+2
I had cause to regenerate gdbsupport/Makefile.in, and noticed some unexpected changes in the copyright header dates. I suspect that this was caused by the end of year date range update process. The Makefile.in contains two date ranges. The first range appears to be the date range for the version of automake being used, that is the range runs up to 2017 only, when automake 1.15.1 was released. The second date range in Makefile.in represents the date range for the generated file, and so, now runs up to 2022. Anyway, this is the result of running autoreconf (using automake 1.15.1) in the gdbsupport directory.

2020-07-30Unify Solaris procfs and largefile handlingRainer Orth1-1/+3
GDB currently doesn't build on 32-bit Solaris: * On Solaris 11.4/x86: In file included from /usr/include/sys/procfs.h:26, from /vol/src/gnu/gdb/hg/master/dist/gdb/i386-sol2-nat.c:24: /usr/include/sys/old_procfs.h:31:2: error: #error "Cannot use procfs in the large file compilation environment" #error "Cannot use procfs in the large file compilation environment" ^~~~~ * On Solaris 11.3/x86 there are several more instances of this. The interaction between procfs and large-file support historically has been a royal mess on Solaris: * There are two versions of the procfs interface: ** The old ioctl-based /proc, deprecated and not used any longer in either gdb or binutils. ** The `new' (introduced in Solaris 2.6, 1997) structured /proc. * There are two headers one can possibly include: ** <procfs.h> which only provides the structured /proc, definining _STRUCTURED_PROC=1 and then including ... ** <sys/procfs.h> which defaults to _STRUCTURED_PROC=0, the ioctl-based /proc, but provides structured /proc if _STRUCTURED_PROC == 1. * procfs and the large-file environment didn't go well together: ** Until Solaris 11.3, <sys/procfs.h> would always #error in 32-bit compilations when the large-file environment was active (_FILE_OFFSET_BITS == 64). ** In both Solaris 11.4 and Illumos, this restriction was lifted for structured /proc. So one has to be careful always to define _STRUCTURED_PROC=1 when testing for or using <sys/procfs.h> on Solaris. As the errors above show, this isn't always the case in binutils-gdb right now. Also one may need to disable large-file support for 32-bit compilations on Solaris. config/largefile.m4 meant to do this by wrapping the AC_SYS_LARGEFILE autoconf macro with appropriate checks, yielding ACX_LARGEFILE. Unfortunately the macro doesn't always succeed because it neglects the _STRUCTURED_PROC part. To make things even worse, since GCC 9 g++ predefines _FILE_OFFSET_BITS=64 on Solaris. So even if largefile.m4 deciced not to enable large-file support, this has no effect, breaking the gdb build. This patch addresses all this as follows: * All tests for the <sys/procfs.h> header are made with _STRUCTURED_PROC=1, the definition going into the various config.h files instead of having to make them (and sometimes failing) in the affected sources. * To cope with the g++ predefine of _FILE_OFFSET_BITS=64, -U_FILE_OFFSET_BITS is added to various *_CPPFLAGS variables. It had been far easier to have just #undef _FILE_OFFSET_BITS in config.h, but unfortunately such a construct in config.in is commented by config.status irrespective of indentation and whitespace if large-file support is disabled. I found no way around this and putting the #undef in several global headers for bfd, binutils, ld, and gdb seemed way more invasive. * Last, the applicability check in largefile.m4 was modified only to disable largefile support if really needed. To do so, it checks if <sys/procfs.h> compiles with _FILE_OFFSET_BITS=64 defined. If it doesn't, the disabling only happens if gdb exists in-tree and isn't disabled, otherwise (building binutils from a tarball), there's no conflict. What initially confused me was the check for $plugins here, which originally caused the disabling not to take place. Since AC_PLUGINGS does enable plugin support if <dlfcn.h> exists (which it does on Solaris), the disabling never happened. I could find no explanation why the linker plugin needs large-file support but thought it would be enough if gld and GCC's lto-plugin agreed on the _FILE_OFFSET_BITS value. Unfortunately, that's not enough: lto-plugin uses the simple-object interface from libiberty, which includes off_t arguments. So to fully disable large-file support would mean also disabling it in libiberty and its users: gcc and libstdc++-v3. This seems highly undesirable, so I decided to disable the linker plugin instead if large-file support won't work. The patch allows binutils+gdb to build on i386-pc-solaris2.11 (both Solaris 11.3 and 11.4, using GCC 9.3.0 which is the worst case due to predefined _FILE_OFFSET_BITS=64). Also regtested on amd64-pc-solaris2.11 (again on Solaris 11.3 and 11.4), x86_64-pc-linux-gnu and i686-pc-linux-gnu. config: * largefile.m4 (ACX_LARGEFILE) <sparc-*-solaris*|i?86-*-solaris*>: Check for <sys/procfs.h> incompatilibity with large-file support on Solaris.

2020-02-13gdbsupport: rename source files to .ccSimon Marchi1-65/+61
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 ...

gdbsupport fails to build with compilers that don't default to C++11 or above. gdbsupport's configure.ac is already using AX_CXX_COMPILE_STDCXX, which sets CXX_DIALECT to the -std=gnu++11 switch if necessary, but the problem is that nowhere are we using CXX_DIALECT.

This moves many needed configure checks from gdb and gdbserver into common.m4. This helps gdbsupport, nat, and target be self-contained.

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.
