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.
* config.in: Regenerate.
