Update GCC to autoconf 2.69, automake 1.15.1

Discussion:

Joseph Myers

2018-10-31 03:26:24 UTC

This patch (diffs to generated files omitted below) updates GCC to use
autoconf 2.69 and automake 1.15.1. (That's not the latest automake
version, but it's the one used by binutils-gdb, with which consistency
is desirable, and in any case seems a useful incremental update that
should make a future update to 1.16.1 easier.)

The changes are generally similar to the binutils-gdb ones, and are
copied from there where shared files and directories are involved
(there are some further changes to such shared directories, however,
which I'd expect to apply to binutils-gdb once this patch is in GCC).
Largely, obsolete AC_PREREQ calls are removed, while many
AC_LANG_SOURCE calls are added to avoid warnings from aclocal and
autoconf. Multilib support is no longer included in core automake,
meaning that multilib.am needs copying from automake's contrib
directory into the GCC source tree. Autoconf 2.69 has Go support, so
local copies of that support are removed. I hope the D support will
soon be submitted to upstream autoconf so the local copy of that can
be removed in a future update.

Note that the regeneration did not include regeneration of
fixincludes/config.h.in (attempting such regeneration resulted in all
the USED_FOR_TARGET conditionals disappearing; and I don't see
anything in the fixincludes/ directory that would result in such
conditionals being generated, unlike in the gcc/ directory). Also
note that libvtv/testsuite/other-tests/Makefile.in was not
regenerated; that directory is not listed as a subdirectory for which
Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm
not sure how it's meant to be regenerated.

While I mostly fixed warnings should running aclocal / automake /
autoconf, there were various such warnings from automake in the
libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos
directories that I did not fix, preferring to leave those to the
relevant subsystem maintainers. Specifically, most of those warnings
were of the following form (example from libgfortran):

Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory,
Makefile.am:48: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled. For now, the corresponding output
automake: object file(s) will be placed in the top-level directory. However,
automake: this behaviour will change in future Automake versions: they
will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.

I think it's best for the relevant maintainers to add subdir-objects
and do any other associated Makefile.am changes needed. In some cases
the paths in the warnings involved ../; I don't know if that adds any
extra complications to the use of subdir-objects.

I've tested this with native, cross and Canadian cross builds. The
risk of any OS-specific issues should I hope be rather lower than if a
libtool upgrade were included (we *should* do such an upgrade at some
point, but it's more complicated - it involves identifying all our
local libtool changes to see if any aren't included in the upstream
version we update to, and reverting an upstream libtool patch that's
inappropriate for use in GCC); I think it would be better to get this
update into GCC so that people can test in different configurations
and we can fix any issues found, rather than to try to get more and
more testing done before it goes in.

This patch (diffs to generated files omitted below) updates GCC to use
autoconf 2.69 and automake 1.15.1.

I think this should fix PR 82856. Maybe you could confirm that this
restores automake functionality with perl 5.6.26, and mention the PR
in the ChangeLog.

Would it make sense to backport because of this?

My understanding is that we need to add 'subdir-objects' to
AM_INIT_AUTOMAKE in configure.ac.

See e.g. https://autotools.io/automake/options.html

(that site is pretty good for describing 'best practices' for modern
autotools; there's unfortunately a lot of very outdated autotools tutorials
around)

Does the regeneration really involve the automake/autoconf part
or would it be feasible to decouple it from --enable-maintainer-mode?

This patch (diffs to generated files omitted below) updates GCC to use
autoconf 2.69 and automake 1.15.1.

I think this should fix PR 82856. Maybe you could confirm that this
restores automake functionality with perl 5.6.26, and mention the PR
in the ChangeLog.

At least, the warnings I saw with an older perl version and automake
1.11.x are gone when using 1.15.1.

I've committed this revised patch version, minus the libgo changes
(note the libgo changes in this version have differences from the
libgo changes in the previous version). A reference to PR
bootstrap/82856 has been added. gcc/doc/install.texi has been updated
to mention the new versions required. Five lib*/testsuite/Makefile.am
files have been updated so they no longer put quotes around their
RUNTEST definitions (old automake stored the RUNTEST definition in a
shell variable in the makefile, new automake uses '$(SHELL) -c
"$(RUNTEST) --version"' which goes wrong when RUNTEST is double-quoted
and ends with a space before the closing double quote; I saw this
cause problems in libphobos testing, but in principle it's an issue
for any of the double-quoted definitions). libphobos and libgo have
-Wno-override added to their AM_INIT_AUTOMAKE calls to avoid warnings
about their testsuite/Makefile.am files overriding RUNTEST and EXPECT
(various other subdirectories already used -Wno-override for that).

As noted, my expectation is that libgfortran, libgo, libgomp,
liboffloadmic, libsanitizer, libphobos maintainers will deal with
moving those directories to subdir-objects, with any consequent fixes
needed, to eliminate the automake warnings about subdirectory sources
without using subdir-objects - and I don't know whether use of ../ in
source paths in some directories complicates things (if subdir-objects
would result in attempts to put resulting objects in ../, outside the
normal build directory for the library) or not.

Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856).

This patch (diffs to generated files omitted below) updates GCC to use
autoconf 2.69 and automake 1.15.1. (That's not the latest automake
version, but it's the one used by binutils-gdb, with which consistency
is desirable, and in any case seems a useful incremental update that
should make a future update to 1.16.1 easier.)

The changes are generally similar to the binutils-gdb ones, and are
copied from there where shared files and directories are involved
(there are some further changes to such shared directories, however,
which I'd expect to apply to binutils-gdb once this patch is in GCC).
Largely, obsolete AC_PREREQ calls are removed, while many
AC_LANG_SOURCE calls are added to avoid warnings from aclocal and
autoconf. Multilib support is no longer included in core automake,
meaning that multilib.am needs copying from automake's contrib
directory into the GCC source tree. Autoconf 2.69 has Go support, so
local copies of that support are removed. I hope the D support will
soon be submitted to upstream autoconf so the local copy of that can
be removed in a future update. Changes to how automake generates
runtest calls mean quotes are removed from RUNTEST definitions in five
lib*/testsuite/Makefile.am files (libatomic, libgomp, libitm,
libphobos, libvtv; some others have RUNTEST definitions without
quotes, which are still OK); libgo and libphobos also get
-Wno-override added to AM_INIT_AUTOMAKE so those overrides of RUNTEST
do not generate automake warnings.

Note that the regeneration did not include regeneration of
fixincludes/config.h.in (attempting such regeneration resulted in all
the USED_FOR_TARGET conditionals disappearing; and I don't see
anything in the fixincludes/ directory that would result in such
conditionals being generated, unlike in the gcc/ directory). Also
note that libvtv/testsuite/other-tests/Makefile.in was not
regenerated; that directory is not listed as a subdirectory for which
Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm
not sure how it's meant to be regenerated.

While I mostly fixed warnings should running aclocal / automake /
autoconf, there were various such warnings from automake in the
libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos
directories that I did not fix, preferring to leave those to the
relevant subsystem maintainers. Specifically, most of those warnings
were of the following form (example from libgfortran):

Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory,
Makefile.am:48: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled. For now, the corresponding output
automake: object file(s) will be placed in the top-level directory. However,
automake: this behaviour will change in future Automake versions: they
will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.

I think it's best for the relevant maintainers to add subdir-objects
and do any other associated Makefile.am changes needed. In some cases
the paths in the warnings involved ../; I don't know if that adds any
extra complications to the use of subdir-objects.

I've tested this with native, cross and Canadian cross builds. The
risk of any OS-specific issues should I hope be rather lower than if a
libtool upgrade were included (we *should* do such an upgrade at some
point, but it's more complicated - it involves identifying all our
local libtool changes to see if any aren't included in the upstream
version we update to, and reverting an upstream libtool patch that's
inappropriate for use in GCC); I think it would be better to get this
update into GCC so that people can test in different configurations
and we can fix any issues found, rather than to try to get more and
more testing done before it goes in.

I've committed this revised patch version

Thank you for taking on this work.

Post by Joseph Myers
As noted, my expectation is that libgfortran, libgo, libgomp,
liboffloadmic, libsanitizer, libphobos maintainers will deal with
moving those directories to subdir-objects, with any consequent fixes
needed, to eliminate the automake warnings about subdirectory sources
without using subdir-objects - and I don't know whether use of ../ in
source paths in some directories complicates things (if subdir-objects
would result in attempts to put resulting objects in ../, outside the
normal build directory for the library) or not.

Turned out that for libgfortran, at least, this doesn't seem trivial.
Problem is that we have some of the sources listed relative to $(srcdir) in
Makefile.am, which breaks when enabling subdir-objects. But we can't remove
the $(srcdir) either, becase these sources in question are generated from
m4 sources when --enable-maintainer-mode is enabled, and $(srcdir) is thus
needed so that the generated files will correctly end up in in the source
tree and not the build tree. Gah!

I filed https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87856 to keep track of
this.

This patch (diffs to generated files omitted below) updates GCC to use
autoconf 2.69 and automake 1.15.1. (That's not the latest automake
version, but it's the one used by binutils-gdb, with which consistency
is desirable, and in any case seems a useful incremental update that
should make a future update to 1.16.1 easier.)
The changes are generally similar to the binutils-gdb ones, and are
copied from there where shared files and directories are involved
(there are some further changes to such shared directories, however,
which I'd expect to apply to binutils-gdb once this patch is in GCC).
Largely, obsolete AC_PREREQ calls are removed, while many
AC_LANG_SOURCE calls are added to avoid warnings from aclocal and
autoconf. Multilib support is no longer included in core automake,
meaning that multilib.am needs copying from automake's contrib
directory into the GCC source tree. Autoconf 2.69 has Go support, so
local copies of that support are removed. I hope the D support will
soon be submitted to upstream autoconf so the local copy of that can
be removed in a future update.
Note that the regeneration did not include regeneration of
fixincludes/config.h.in (attempting such regeneration resulted in all
the USED_FOR_TARGET conditionals disappearing; and I don't see
anything in the fixincludes/ directory that would result in such
conditionals being generated, unlike in the gcc/ directory). Also
note that libvtv/testsuite/other-tests/Makefile.in was not
regenerated; that directory is not listed as a subdirectory for which
Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm
not sure how it's meant to be regenerated.
While I mostly fixed warnings should running aclocal / automake /
autoconf, there were various such warnings from automake in the
libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos
directories that I did not fix, preferring to leave those to the
relevant subsystem maintainers. Specifically, most of those warnings
Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory,
Makefile.am:48: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled. For now, the corresponding output
automake: object file(s) will be placed in the top-level directory. However,
automake: this behaviour will change in future Automake versions: they
will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.
I think it's best for the relevant maintainers to add subdir-objects
and do any other associated Makefile.am changes needed. In some cases
the paths in the warnings involved ../; I don't know if that adds any
extra complications to the use of subdir-objects.
I've tested this with native, cross and Canadian cross builds. The
risk of any OS-specific issues should I hope be rather lower than if a
libtool upgrade were included (we *should* do such an upgrade at some
point, but it's more complicated - it involves identifying all our
local libtool changes to see if any aren't included in the upstream
version we update to, and reverting an upstream libtool patch that's
inappropriate for use in GCC); I think it would be better to get this
update into GCC so that people can test in different configurations
and we can fix any issues found, rather than to try to get more and
more testing done before it goes in.

OK.

Thanks for the work!
Richard.

Thanks for doing this. As usual, please skip the patch to the libgo
directory; I'll commit that myself. The patch to gotools is fine to
commit any time you are ready.

Whenever you feel like bumping gcc to 1.16.1, I can take care of binutils-gdb.

Before possibly doing that we should get shared files back in sync again.

I've just applied my changes to shared files (where they went beyond
yours) to binutils-gdb, and also merged a couple of other config/ changes
from GCC to binutils-gdb (and done the consequent configure regenerations
in libdecnumber and zlib). There are also libiberty changes, and changes
to shared various top-level files, that need to be got back in sync. I
haven't examined them in detail but it seems mostly to be changes on the
GCC side needing to be applied to binutils-gdb.

Thanks so much for doing this; I've been looking forward to it!

Post by Joseph Myers
The changes are generally similar to the binutils-gdb ones, and are
copied from there where shared files and directories are involved
(there are some further changes to such shared directories, however,
which I'd expect to apply to binutils-gdb once this patch is in GCC).
Largely, obsolete AC_PREREQ calls are removed, while many
AC_LANG_SOURCE calls are added to avoid warnings from aclocal and
autoconf. Multilib support is no longer included in core automake,
meaning that multilib.am needs copying from automake's contrib
directory into the GCC source tree. Autoconf 2.69 has Go support, so
local copies of that support are removed. I hope the D support will
soon be submitted to upstream autoconf so the local copy of that can
be removed in a future update.

Hopefully upstream autoconf will release 2.70 soon; it's been several
years since a 2.70 release has been requested, but no one with the
proper privileges has had the time to pull one together...

Post by Joseph Myers
Note that the regeneration did not include regeneration of
fixincludes/config.h.in (attempting such regeneration resulted in all
the USED_FOR_TARGET conditionals disappearing; and I don't see
anything in the fixincludes/ directory that would result in such
conditionals being generated, unlike in the gcc/ directory). Also
note that libvtv/testsuite/other-tests/Makefile.in was not
regenerated; that directory is not listed as a subdirectory for which
Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm
not sure how it's meant to be regenerated.
While I mostly fixed warnings should running aclocal / automake /
autoconf, there were various such warnings from automake in the
libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos
directories that I did not fix, preferring to leave those to the
relevant subsystem maintainers. Specifically, most of those warnings
Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory,
Makefile.am:48: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the
'subdir-objects'
automake: automake option hasn't been enabled. For now, the corresponding output
automake: object file(s) will be placed in the top-level directory.
However,
automake: this behaviour will change in future Automake versions: they
will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.
I think it's best for the relevant maintainers to add subdir-objects
and do any other associated Makefile.am changes needed. In some cases
the paths in the warnings involved ../; I don't know if that adds any
extra complications to the use of subdir-objects.
I've tested this with native, cross and Canadian cross builds. The
risk of any OS-specific issues should I hope be rather lower than if a
libtool upgrade were included (we *should* do such an upgrade at some
point, but it's more complicated - it involves identifying all our
local libtool changes to see if any aren't included in the upstream
version we update to, and reverting an upstream libtool patch that's
inappropriate for use in GCC); I think it would be better to get this
update into GCC so that people can test in different configurations
and we can fix any issues found, rather than to try to get more and
more testing done before it goes in.

As this is code shared with binutils-gdb, I was copying the change made
there. (Plus the include of $(top_srcdir)/../multilib.am because zlib can
be built as a target module in GCC.)

the paths in the warnings involved ../; I don't know if that adds any
extra complications to the use of subdir-objects.

I did encounter a problem with ../zlib in libphobos (it built all zlib
objects in-tree). Re-adding target-zlib and using libz_convenience.la
is what I probably should be doing though. Attaching a draft patch
for that.
