    • Fix splay tree KEY leak detected in GDB test gdb.base/macscp.exp · f9f75f8d 
      When a node is removed from a splay tree, the splay tree was
not using the function splay_tree_delete_key_fn to release the key.
This was causing a leak, fixed by Tom Tromey.

This patch fixes another key leak, that happens when a key equal to
a key already present is inserted.  In such a case, we have to release
the old KEY.
Note that this is based on the assumption that the caller always
allocates a new KEY when doing an insert.

Also, clarify the documentation about when the release functions are
called.

    • Fix leak in splay-tree · 2197ea17 
      Philippe Waroquiers noticed a memory leak in gdb, which he tracked
down to a bug in splay-tree.  splay_tree_remove does not call the
`delete_key' function when it removes the old node; but it should.

I looked at every splay tree in GCC and there is only one that passes
a non-NULL delete function -- the one in lto.c.  That file does not
call splay_tree_remove.  So, I think this is safe to check in.

I re-ran the LTO tests to double check.

    • Implement P0732R2, class types in non-type template parameters. · 4be5c72c 
      There is one significant piece of this that is not implemented yet: the
reliance on defaulted operator<=>, which someone else has been working on.
So, for the moment those lines are commented out of the testcases.

One tricky bit was treating template parameters of classtype as const
lvalues without making their decltype const; for this I used a
VIEW_CONVERT_EXPR wrapper, which previously could only appear in templates
as location wrappers.

The user-defined literal parts of P0732R2 are in the next patch.

    • Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856). · 22e05272 
      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.

    • PR82687, g++.dg/asan/default-options-1.C fails with PR82575 fix · 160826fe 
      The problem with making discarded symbols hidden is that the
non-default visibility is sticky.  When symbols other than the
__gnu_lto ones are discarded that turns out to be a bad idea.

	PR lto/82575
	* simple-object-elf.c (simple_object_elf_copy_lto_debug_sections):

    • PR82575, lto debugobj references __gnu_lto_slim, ld test liblto-17 fails · ebd208bf 
      If __gnu_lto_slim is global, undefined, default visibility in the
early debug object, then it finds its way into .dynsym when creating
shared libraries.  __gnu_lto_slim in a symbol table (.dynsym or
.symtab) signals nm and other binutils that the object is an LTO
object needing a plugin, but that isn't the case for the ld liblti-17
tests.  So, make __gnu_lto_slim hidden to prevent it becoming
dynamic.  Further, make it weak because some linkers may warn on
finding an undefined global non-default visibility symbol.

	PR lto/82575
	* simple-object-elf.c (simple_object_elf_copy_lto_debug_sections):
	Make discarded non-local symbols weak and hidden.

    • Add DW_CFA_AARCH64_negate_ra_state to dwarf2.def/h and dwarfnames.c · ff971abe 
        A new vendor CFA DW_CFA_AARCH64_negate_ra_state was introduced for ARMv8.3-A
return address signing, it is multiplexing DW_CFA_GNU_window_save in CFA vendor
extension space.

  This patch adds necessary code to make it available to external, the GDB
patch (https://sourceware.org/ml/gdb-patches/2017-08/msg00215.html) is intended
to use it.

  A new DW_CFA_DUP for it is added in dwarf2.def.  The use of DW_CFA_DUP is to
avoid duplicated case value issue when included in libiberty/dwarfnames.

  Native x86 builds OK to make sure no macro expanding errors.

Committed on behalf of Jiong Wang.

    include/
	* dwarf2.def (DW_CFA_AARCH64_negate_ra_state): New DW_CFA_DUP.
	* dwarf2.h (DW_CFA_DUP): New define.
