ae6cf62861 Cygwin/MinGW: Do not version lto plugins
GCC on Linux already uses liblto_plugin.so directly without
the libtool version suffix, adjust windows GCC to do the same.

gcc/ChangeLog:

	* config.host: Adjust plugin name for Windows.

lto-plugin/ChangeLog:

	* Makefile.am: drop versioning from libtool completely.
	* Makefile.in: regenerate.

ad2a37157d If the lto plugin encounters a file with multiple symbol sections, each of which also has a v1 symbol extension section[1] then it will attempt to read the extension data for *every* symbol from each of the extension sections. This results in reading off the end of a buffer with the associated memory corruption that that entails. This patch fixes that problem.
2020-09-09  Nick Clifton  <nickc@redhat.com>

	* lto-plugin.c (struct plugin_symtab): Add last_sym field.
	(parse_symtab_extension): Only read as many entries as are
	available in the buffer.  Store the data read into the symbol
	table indexed from last_sym.  Increment last_sym.

1dedc12d18 revamp dump and aux output names
This patch simplifies (!!!) the logic governing the naming of dump
files and auxiliary output files in the driver, in the compiler, and
in the LTO wrapper.  No changes are made to the naming of primary
outputs, there are often ways to restore past behavior, and a number
of inconsistencies are fixed.  Some internal options are removed
(-auxbase and -auxbase-strip), sensible existing uses of -dumpdir and
-dumpbase options remain unchanged, additional useful cases are added,
making for what is still admittedly quite complex.  Extensive
documentation and testcases provide numerous examples, from normal to
corner cases.

The most visible changes are:

- aux and dump files now always go in the same directory, that
defaults to the directory of the primary output, but that can be
overridden with -dumpdir, -save-temps=*, or, preserving past behavior,
with a -dumpbase with a directory component.

- driver and compiler now have the same notion of naming of auxiliary
outputs, e.g. .dwo files will no longer be in one location while the
debug info suggests they are elsewhere, and -save-temps and .dwo
auxiliary outputs now go in the same location as .su, .ci and
coverage data, with consistent naming.

- explicitly-specified primary output names guide not only the
location of aux and dump outputs: the output base name is also used in
their base name, as a prefix when also linking (e.g. foo.c bar.c -o
foobar creates foobar-foo.dwo and foobar-bar.dwo with -gsplit-dwarf),
or as the base name instead of the input name (foo.c -c -o whatever.o
creates whatever.su rather than foo.su with -fstack-usage).  The
preference for the input file base name, quite useful for our
testsuite, can be restored with -dumpbase "".  When compiling and
linking tests in the testsuite with additional inputs, we now use this
flag.  Files named in dejagnu board ldflags, libs, and ldscripts are
now quoted in the gcc testsuite with -Wl, so that they are not counted
as additional inputs by the compiler driver.

- naming a -dumpbase when compiling multiple sources used to cause
dumps from later compiles to overwrite those of earlier ones; it is
now used as a prefix when compiling multiple sources, like an
executable name above.

- the dumpbase, explicitly specified or computed from output or input
names, now also governs the naming of aux outputs; since aux outputs
usually replaced the suffix from the input name, while dump outputs
append their own additional suffixes, a -dumpbase-ext option is
introduced to enable a chosen suffix to be dropped from dumpbase to
form aux output names.

- LTO dump and aux outputs were quite a mess, sometimes leaking
temporary output names into -save-temps output names, sometimes
conversely generating desirable aux outputs in temporary locations.
They now obey the same logic of compiler aux and dump outputs, landing
in the expected location and taking the linker output name or an
explicit dumpbase overrider into account.

- Naming of -fdump-final-insns outputs now follows the dump file
naming logic for the .gkd files, and the .gk dump files generated in
the second -fcompare-debug compilation get the .gk inserted before the
suffix that -dumpbase-ext drops in aux outputs.

5269b24605 Silence warning in LTO mode on VxWorks
The link phase is always partial (-r) for VxWorks in kernel mode, which
means that it uses incremental LTO linking by default (-flinker-output=rel).
But in this mode the LTO plugin outputs a warning if one of the object files
involved in the link does not contain LTO bytecode, before switching to
nolto-rel mode.  We do not do repeated incremental linking for VxWorks so
silence the warning.

8fc8bf801e Enable Intel CET in liblto_plugin.so on Intel CET enabled host
Since ld is Intel CET enabled on Intel CET enabled host, dlopen fails on
liblto_plugin.so if it isn't Intel CET enabled.  Add GCC_CET_HOST_FLAGS
to cet.m4, use it in libiberty and lto-plugin to always enable Intel
CET in liblto_plugin.so on Intel CET enabled host.

On Linux/x86 host, enable Intel CET by default if assembler and compiler
support Intel CET so that the generated liblto_plugin.so can be used on
both CET and non-CET machines.  It is an error to disable Intel CET in
liblto_plugin.so on Intel CET enabled host.

c101cff86e lto-plugin - support -save-temps, -v, --version.
This patch makes the lto-plugin follow the same approach
to save-temps as collect2. 

-save-temps causes the temp file to be named meaningfully,
and for the relevant input files to be saved in CWD.

-v, —version causes the save actions to be output to stderr.

one can get this to happen by just putting -save-temps, -v on
the regular link line or (for compatibility with the way the
 -debug flag works) by appending -plugin-opt=-save-temps, etc.

22e0527251 Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856).
This patch 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.
