The PR is about a set of tests that were not executed because of
missing asm support.
However, the assembler can handle the insns now, so the tests are
attempted (but with a missing asm shim they fail).
This adds the shim.
In principle (bugs notwithstanding) Darwin’s x86_64 ABI is supposed
to follow the sysv psABI so we can have essentially a copy of the
Linux one.

The c-c++-common tests fail (or XPASS depending on which) on
powerpc Darwin because it doesn't currently emit .ident marker.
Since there's no support for .ident in the assembler, we can't
enable the output and therefore these tests should be skipped.

This corrects a long-standing misconfiguration for Darwin.
The assembler supports the “.file” and “.loc” directives, but
the GCC configury was not detecting this because it was
using objdump, which does not exist on most Darwin installations.
We added support for “otool” to GCC and now we can use that to
make the check that’s done with objdump on ELF targets.

During 8.x, the rs6000 target-specific mangling was reorganised which uncovered
a long-standing bug in Darwin’s mangling for ‘IBM’ long double. Now the symbols

This patch adds the necessary subset of the Linux long double exports to Darwin’s

On some version of dejagnu, options in RUNTESTFLAGS are appended to the
command-line and thus any -mfloat-abi=softfp or -mfloat-abi=hard in
there overwrite the -mfloat-abi=soft in the dg-options for
size-optimization-ieee-* tests. Test is still run though because
arm_soft_ok returns true if -mfloat-abi=soft is accepted, even if the
file is not compiled for softfloat due to a later -mfloat-abi on the
command line.
This patch adds a dg-skip-if to those tests to ensure they are not run
