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.
Only disable large-file support and perhaps plugins if needed.
Set, substitute LARGEFILE_CPPFLAGS if so.
