Segher Boessenkool 4144e4e301 Build crt*vr.S with AltiVec enabled
These files won't build on targets that do not have AltiVec enabled,
breaking the build, unless we tell GAS that Altivec insns are fine.
The alternative is to not build these files in that case, which is much
more complicated.

Segher Boessenkool 7502c5970d rs6000: float128 on BE and 32-bit
This fixes float128 on BE and on 32-bit.

The configure tests need to use -mabi=altivec for 32-bit, since it is
not the default there.  That also enables the "vector" keyword, used by
the tests.  To do this it temporarily adds a few flags to the CFLAGS
variable.

It also fixes a syntax error in the libgcc_cv_powerpc_float128_hw test
(the function name was missing in the function declaration).

Regenerating config.in (via autoreconf) removed the duplicate definition
of HAVE_SOLARIS_CRTS.

Finally, this adds a "-mfloat128-hardware requires -m64" test to
rs6000.c: all the current patterns need 64-bit registers.  Maybe we'll
want to add float128 hardware support to 32-bit some day, but certainly
not today.


	* config/rs6000/rs6000.c (rs6000_option_override_internal): Disallow
	-mfloat128-hardware without -m64.

libgcc/
	* configure.ac (test for libgcc_cv_powerpc_float128): Temporarily
	modify CFLAGS.  Add -mabi=altivec -mvsx -mfloat128.
	(test for libgcc_cv_powerpc_float128_hw): Add -mpower9-vector and
	-mfloat128-hardware to the CFLAGS.  Fix syntax error in the C snippet.
	* configure: Regenerate.

Joseph Myers fec5f4e041 Make MIPS soft-fp preserve NaN payloads for NAN2008.
The MIPS sfp-machine.h has an _FP_CHOOSENAN implementation which
emulates hardware semantics of not preserving signaling NaN payloads
for an operation with two NaN arguments (although that doesn't suffice
to avoid sNaN payload preservation in any case with just one NaN
argument).

However, those are only hardware semantics in the legacy NaN case; in
the NAN2008 case, the architecture documentation says hardware
preserves payloads in such cases.  Furthermore, this implementation
assumes legacy NaN semantics, so in the NAN2008 case the
implementation actually has the effect of preserving sNaN payloads but
not preserving qNaN payloads, when both should be preserved.

This patch fixes the code just to copy from the first argument (at the
level of libgcc, it's not meaningful which argument is the first and
which is the second).

Tested for mips64-linux-gnu (soft float, NAN2008) with the glibc math/
tests.

	* config/mips/sfp-machine.h (_FP_CHOOSENAN): Always preserve NaN
	payload if [__mips_nan2008].

Iain Sandoe b410cf1dc0 [Darwin] fix PR67710 by updating 'as' specs to handle newer assembler versions.
A/ Newer versions of ld64 check the min_version command, and newer versions of
   the system assembler inserts this in response to "-mmacosx-version-min=" on
   the assembler line. Unless one makes sensible versions, some object is bound
   to conflict.

B/ Additionally, there's a difference in behaviour between "as" and "ld" when
   presented with xx.yy.zz (ld truncates to xx.yy, as doesn't); net result is
   that one needs to pass a truncated version to "as".

So (if the assembler supports minversion commands)
(a) provide a truncated minversion (as asm_macosx_version_min, which is a
    driver-only var).
(b) pass this to "as"
(c) Update tests to determine 'HAVE_AS_MMACOSX_VERSION_MIN_OPTION'
    (Rainer's patch)
(d) For some reason the testcases are "run" (it's not obvious they need to be,
    they are checking compile-time issues)
  - anyway, to preserve the status quo, I've left them as exec.  However, the
    minimum version that can be code-gened for is target-dependent (there are no
    released x86 versions before 10.4, for example).  To avoid conflicts where
    the "as" is assuming some minimum, I've set the testversion to 10.5 (which
    is supported by all the archs we have)
(e) We need to ensure that libgcc and crts are generated with a sufficiently
    old minversion not to conflict.
