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.

The following patch moves the fast_hash function, which uses libxxhash,
to gdbsupport. Move the libxxhash configure check to gdbsupport (and
transitively to gdbserver).

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.

This pulls out the implementation of an event pipe used to implement
target async support in both linux-low.cc (gdbserver) and linux-nat.c
(gdb).
This will be used to replace the existing event pipe in linux-low.cc
and linux-nat.c in future commits.

This moves the gdb_regex convenience class to gdbsupport.
|
|
gdb has some extensions and helpers for working with the libiberty
hash table. This patch consolidates these and moves them to
gdbsupport.
|
|
This moves the gdb-specific obstack code -- both extensions like
obconcat and obstack_strdup, and things like auto_obstack -- to
gdbsupport.

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.

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.

This moves the simple_search_memory function to a new file,
gdbsupport/search.cc. The API is slightly changed to make it more
general. This generality is useful for wiring it to gdbserver, and
also for unit testing.

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.

It looks like after doing last minute changes to Makefile.am in commit

re-generate Makefile.in. This patch fixes it.

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.

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 fixes it.

I'm seeing this on F27 (a clean build from scratch):
~~~~~~~~~~~~~~~~~~~~~~~~~~~
make[3]: Entering directory '/home/pedro/brno/pedro/gdb/binutils-gdb/build/gdbsupport'

~~~~~~~~~~~~~~~~~~~~~~~~~~~
libc-config.h, where it includes config.h, says:
~~~~~~~~~~~~~~~~~~~~~~~~~~~
/* This is intended to be a good-enough substitute for glibc system
macros like those defined in <sys/cdefs.h>, so that Gnulib code
shared with glibc can do this as the first #include:
#ifndef _LIBC

#endif

part of Gnulib this includes Gnulib's <config.h> and defines macros

#include <config.h>
~~~~~~~~~~~~~~~~~~~~~~~~~~~
The issue is that that '#include <config.h>' picks up bfd's config.h
instead of gnulib's.
This problem doesn't trigger in the gdb dir because there we generate
config.h under that exact name so gnulib's libc-config.h ends up
picking gdb's config.h instead of gnulib.c and that ends up harmless.
In gdbsupport, the config.h file is really named support-config.h, so
that '#include <config.h>' in libc-config.h doesn't pick it like it
would if it had the conventional config.h name.
This patch fixes it by simply renaming gdbserver's support-config.h to
config.h.

This moves many needed configure checks from gdb and gdbserver into
common.m4. This helps gdbsupport, nat, and target be self-contained.
The result is a bit spaghetti-ish, because gdbsupport uses another m4
file from gdb/. The resulting code is somewhat non-obvious. However,
these problems already exist, so it's not really that much worse than
what is already done.

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.
