[RS6000] PR88614, output_operand: invalid %z value
The direct cause of this PR is the fact that tls_gdld_nomark didn't
handle indirect calls. Also, most indirect calls were being optimised
back to direct calls anyway, due to tls_gdld_nomark not checking any
of the parallel elements except the first (plus the extra element that
distinguishes this call from normal calls). There were other unwanted
substitutions too.
So this patch attacks the problem of handling special calls in a
different way. Rather than adding another element to the call insn
parallel to distinguish -mno-tls-markers __tls_get_addr calls from any
other calls, we now inspect the second CALL arg. Each
call_value_nonlocal and call_value_indirect insn now checks for the
tlsgd/ld unspecs when !TARGET_TLS_MARKERS and emits the arg setup
insns. I disallow the local call patterns since we'll only see local
calls to __tls_get_addr in testcases, and it doesn't seem a good idea
to complicate the patterns just for a minor optimisation. Sibling
call insns aren't used for libcalls, so none of these insns need to
change.
The patch also fixes a minor problem with -mno-tls-markers
__tls_get_addr calls causing a "li 3,0" instruction to be emitted
prior to the arg setup instructions, due to using a libcall with one
arg. That isn't correct when the call insn itself sets up its arg.
Also, I've tidied the V4 secure-plt calls, generating them in
rs6000_call_sysv rather than by splitting in rs6000.md. The
CALL_INSN_FUNCTION_USAGE added in edit_tls_call_insn is no longer
needed (since git commit
0a4b5c66df9).
On the subject of unwanted substitutions, I also saw a
_GLOBAL_OFFSET_TABLE_ symbol_ref being substituted for the GOT reg,
resulting in code like "addi 3,_GLOBAL_OFFSET_TABLE_,tls_ld@got@tlsld".
Fixed by the unspec_tls change.

compiler: stop iterator on error
If there is an error reading or parsing an archive header, the
Archive_iterator code would return a dummy header but would not mark
itself as done. The effect is that an invalid archive leads to an
endless loop reading and re-reading the same archive header. Avoid
that by setting the offset to the end of the file, which will cause
the iterator to == archive_end.
No test since it doesn't seem worth constructing an invalid archive.

Fix leak in splay-tree
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.

PR libstdc++/88782 avoid ODR problems in std::make_shared
The old version of _Sp_counted_ptr_inplace::_M_get_deleter (up to GCC
8.2.0) expects to be passed a real std::typeinfo object, so mixing that
with the new definition of the __shared_ptr constructor (which always
passes the fake tag) leads to accessing the fake object as a real
std::typeinfo. Instead of trying to make it safe to mix the old and new
definitions, just stop using that function. By passing a reference to
__shared_ptr::_M_ptr to the __shared_count constructor it can be set
directly, without needing to obtain the pointer via the _M_get_deleter
back-channel. This avoids a virtual dispatch (which fixes PR 87514).
This means that code built against new libstdc++ headers doesn't use
_M_get_deleter at all, and so make_shared works the same whether RTTI is
enabled or not.
Also change _M_get_deleter so that it checks for a real type_info object
even when RTTI is disabled, by calling a library function. Unless
libstdc++ itself is built without RTTI that library function will be
able to test if it's the right type_info. This means the new definition
of _M_get_deleter can handle both the fake type_info tag and a real
type_info object, even if built without RTTI.
If linking to objects built against older versions of libstdc++ then if
all objects use -frtti or all use -fno-rtti, then the caller of
_M_get_deleter and the definition of _M_get_deleter will be consistent
and it will work. If mixing -frtti with -fno-rtti it can still fail if
the linker picks an old definition of _M_get_deleter and an old
__shared_ptr constructor that are incompatible. In that some or all
objects might need to be recompiled.

Ignore LLVM's blank lines.
The GCN toolchain must use the LLVM assembler and linker because there's no
binutils port. The LLVM tools do not have the same diagnostic style as
binutils, so the "blank line(s) in output" tests are inappropriate (and very
noisy).
The LLVM tools also have different command line options, so it's not possible
to autodetect object formats in the same way.

description has been broken out to avoid the mailing list size limit.
The back-end contains various bits that support OpenACC and OpenMP, but the
middle-end and libgomp patches are missing, as is mkoffload. I include them
here because they're harmless and carving up the files seems like unnecessary
effort. The remaining offload support will be posted at a later date.
The gcn-run.c is a separate tool that can run a GCN program on a GPU using
the ROCm drivers and HSA runtime libraries.

[AArch64] Initial -mcpu=ares tuning
This patch adds a tuning struct for the Arm Ares CPU and uses it for -m{cpu,tune}=ares.
The tunings are an initial attempt and may be improved upon in the future, but they serve
as a decent starting point for GCC 9.
With this I see a 1.3% improvement on SPEC2006 int and 0.3% on SPEC2006 fp with -mcpu=ares.
On SPEC2017 I see a 0.6% improvement in intrate and changes in the noise for fprate.
