[RS6000] "G" and "H" constraints
The patch fixes two cases where the "G" and "H" constraints were used
incorrectly. Their purpose is calculating insn lengths. Thus it
never makes sense to put "GH" together or with "F" in an insn
alternative.
movdi_internal32 used "GHF" in an alternative so I replaced that with
"F", and added length attributes for the insn, which were missing.
There are some formatting changes too, to make alternatives line up
with attributes.
The FMOVE128 version of mov<mode>_softfloat also had "GHF" in an
alternative, so "GH" is dropped and "F" moved to a separate
alternative in order to get insn lengths correct. Well by correct I
mean we need to choose the maximum insn length otherwise branches
might not reach. Note the very large length for "F". I think it
would be better to force soft-float long double constants to memory in
64-bit mode, but that's a patch for another day.

[RS6000] inline plt call sequences
Finally, the point of the previous patches in this series, support for
inline PLT calls, keyed off -fno-plt. This emits code using new
relocations that tie all insns in the sequence together, so that the
linker can edit the sequence back to a direct call should the call
target turn out to be local. An example of ELFv2 code to call puts is
as follows:
.reloc .,R_PPC64_PLTSEQ,puts
std 2,24(1)
.reloc .,R_PPC64_PLT16_HA,puts
addis 12,2,0
.reloc .,R_PPC64_PLT16_LO_DS,puts
ld 12,0(12)
.reloc .,R_PPC64_PLTSEQ,puts
mtctr 12
.reloc .,R_PPC64_PLTCALL,puts
bctrl
ld 2,24(1)
"addis 12,2,puts@plt@ha" and "ld 12,puts@plt@l(12)" are also supported
by the assembler. gcc instead uses the explicit R_PPC64_PLT16_HA and
R_PPC64_PLT16_LO_DS relocs because when the call is to __tls_get_addr
an extra reloc is emitted at every place where one is shown above, to
specify the __tls_get_addr arg. The linker expects the extra reloc to
come first. .reloc enforces that ordering.
The patch also changes code emitted for longcalls if the assembler
supports the new marker relocs, so that these too can be edited. One
side effect of longcalls using PLT16 relocs is that they can now be
resolved lazily by ld.so.
I don't support lazy inline PLT calls for ELFv1, because ELFv1 would
need barriers to reliably load both the function address and toc
pointer from the PLT. ELFv1 -fno-plt uses the longcall sequence
instead, which isn't edited by GNU ld.

[RS6000] Use standard call patterns for __tls_get_addr calls
The current code handling __tls_get_addr calls for powerpc*-linux
generates a call then overwrites the call insn with a special
tls_{gd,ld}_{aix,sysv} pattern. It's done that way to support
!TARGET_TLS_MARKERS, where the arg setup insns need to be emitted
immediately before the branch and link. When TARGET_TLS_MARKERS, the
arg setup insns are split from the actual call, but we then have a
non-standard call pattern that needs to be carried through to output.
This patch changes that scheme, to instead use the standard call
patterns for __tls_get_addr calls, except for the now rare
!TARGET_TLS_MARKERS case. Doing it this way should be better for
maintenance as the !TARGET_TLS_MARKERS code can eventually disappear.
It also makes it possible to support longcalls (and in following
patches, inline plt calls) for __tls_get_addr without introducing yet
more special call patterns.
__tls_get_addr calls do however need to be different to standard
calls, because when TARGET_TLS_MARKERS the calls are decorated with an
argument specifier, eg. "bl __tls_get_addr(thread_var@tlsgd)" that
causes a reloc to be emitted by the assembler tying the call to its
arg setup insns. I chose to smuggle the arg in the currently unused
stack size rtl.
I've also introduced rs6000_call_sysv to generate rtl for sysv calls,
as rs6000_call_aix does for aix and elfv2 calls. This allows
rs6000_longcall_ref to be local to rs6000.c since the calls in the
expanders never did anything for darwin.

libphobos: Merge common version blocks using arch_any conditions
This sets a precedence in upstream for merging architecture agnostic
C bindings into one block, rather than separate duplicated blocks.
A nice side-effect is it almost completes the C bindings for
s390-linux-gnu and sparc-linux-gnu, and fixes a bug on MIPS32 where
O_SYNC had the wrong value.

PR libstdc++/67843 set shared_ptr lock policy at build-time
This resolves a longstanding issue where the lock policy for shared_ptr
reference counting depends on compilation options when the header is
included, so that different -march options can cause ABI changes. For
example, objects compiled with -march=armv7 will use atomics to
synchronize reference counts, and objects compiled with -march=armv5t
will use a mutex. That means the shared_ptr control block will have a
different layout in different objects, causing ODR violations and
undefined behaviour. This was the root cause of PR libstdc++/42734 as
well as PR libstdc++/67843.
The solution is to decide on the lock policy at build time, when
libstdc++ is configured. The configure script checks for the
availability of the necessary atomic built-ins for the target and fixes
that choice permanently. Different -march flags used to compile user
code will not cause changes to the lock policy. This results in an ABI
change for certain compilations, but only where there was already an ABI
incompatibility between the libstdc++.so library and objects built with
an incompatible -march option. In general, this means a more stable ABI
that isn't silently altered when -march flags make addition atomic ops
available.
To force a target to use "atomic" or "mutex" the new configure option
--with-libstdcxx-lock-policy can be used.
In order to turn ODR violations into linker errors, the uses of
shared_ptr in filesystem directory iterators have been replaced
with __shared_ptr, and explicit instantiations are declared. This
ensures that object files using those types cannot link to libstdc++
libs unless they use the same lock policy.

MIPS: Add `-mfix-r5900' option for the R5900 short loop erratum
The short loop bug under certain conditions causes loops to
execute only once or twice, due to a hardware bug in the R5900 chip.
`-march=r5900' already enables the R5900 short loop workaround.
However, the R5900 ISA and most other MIPS ISAs are mutually
exclusive since R5900-specific instructions are generated as well.
The `-mfix-r5900' option can be used in combination with e.g.
`-mips2' or `-mips3' to generate generic MIPS binaries that also
work with the R5900 target. The workaround is implemented by GAS
rather than by GCC.
The following small `shortloop.c' file has been used as a test
with GCC 8.2.0:
void shortloop(void)
{
__asm__ __volatile__ (
" li $3, 300\n"
"loop:\n"
" addi $3, -1\n"
" addi $4, -1\n"
" bne $3, $0, loop\n"
" li $4, 3\n"
::);
}
The following six combinations have been tested:
% mipsr5900el-unknown-linux-gnu-gcc -O1 -c shortloop.c
% mipsr5900el-unknown-linux-gnu-gcc -O1 -c shortloop.c -mfix-r5900
% mipsr5900el-unknown-linux-gnu-gcc -O1 -c shortloop.c -mno-fix-r5900
% mipsr4000el-unknown-linux-gnu-gcc -O1 -c shortloop.c
% mipsr4000el-unknown-linux-gnu-gcc -O1 -c shortloop.c -mfix-r5900
% mipsr4000el-unknown-linux-gnu-gcc -O1 -c shortloop.c -mno-fix-r5900
The R5900 short loop erratum is corrected in exactly three cases:
1. for the target `mipsr5900el' by default;
2. for the target `mipsr5900el' with `-mfix-r5900';
3. for any other MIPS target (e.g. `mipsr4000el') with `-mfix-r5900'.
In all other cases the correction is not made.

Fix missing dump_impl_location_t values, using a new dump_metadata_t
The dump_* API attempts to capture emission location metadata for the
various dump messages, but looking in -fsave-optimization-record shows
that many dump messages are lacking useful impl_location values, instead
having this location within dumpfile.c:
"impl_location": {
"file": "../../src/gcc/dumpfile.c",
"function": "ensure_pending_optinfo",
"line": 1169
},
The problem is that the auto-capturing of dump_impl_location_t is tied to
dump_location_t, and this is tied to the dump_*_loc calls. If a message
comes from a dump_* call without a "_loc" suffix (e.g. dump_printf), the
current code synthesizes the dump_location_t within
dump_context::ensure_pending_optinfo, and thus saves the useless
impl_location seen above.
This patch fixes things by changing the dump_* API so that, rather than
taking a dump_flags_t, they take a new class dump_metadata_t, which is
constructed from a dump_flags_t, but captures the emission location.
Hence e.g.:
dump_printf (MSG_NOTE, "some message\n");
implicitly builds a dump_metadata_t wrapping the MSG_NOTE and the
emission location. If there are several dump_printf calls without
a dump_*_loc call, the emission location within the optinfo is that
of the first dump call within it.
The patch updates selftest::test_capture_of_dump_calls to verify
that the impl location of various dump_* calls is captured. I also
verified things manually.
