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. From-SVN: r246043
