configure.ac: Add GAS check for LEON instructions on SPARC.
* configure.ac: Add GAS check for LEON instructions on SPARC. * configure: Regenerate. * config.in: Likewise. * config.gcc (with_cpu): Remove sparc-leon*-* and deal with LEON in the sparc*-*-* block. * config/sparc/sparc.opt (LEON, LEON3): New masks. * config/sparc/sparc.h (ASM_CPU32_DEFAULT_SPEC): Set to AS_LEON_FLAG for LEON or LEON3. (ASM_CPU_SPEC): Pass AS_LEON_FLAG if -mcpu=leon or -mcpu=leon3. (AS_LEON_FLAG): New macro. * config/sparc/sparc.c (sparc_option_override): Set MASK_LEON for leon and MASK_LEON3 for leon3 and unset them if HAVE_AS_LEON is not defined. Deal with LEON and LEON3 for the memory model. * config/sparc/sync.m (atomic_compare_and_swap<mode>): Enable for LEON3 (atomic_compare_and_swap<mode>_1): Likewise. (*atomic_compare_and_swap<mode>_1): Likewise. From-SVN: r201622
