(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): Enable for LEON3 (atomic_compare_and_swap_1): Likewise. (*atomic_compare_and_swap_1): Likewise. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@201622 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/configure.ac | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'gcc/configure.ac') diff --git a/gcc/configure.ac b/gcc/configure.ac index b279373410a..116ba133145 100644 --- a/gcc/configure.ac +++ b/gcc/configure.ac @@ -3613,6 +3613,19 @@ foo: kasumi_fi_xor %f46, %f48, %f50, %f52],, [AC_DEFINE(HAVE_AS_SPARC4, 1, [Define if your assembler supports SPARC4 instructions.])]) + + gcc_GAS_CHECK_FEATURE([LEON instructions], + gcc_cv_as_sparc_leon,, + [-Aleon], + [.text + .register %g2, #scratch + .register %g3, #scratch + .align 4 + smac %g2, %g3, %g1 + umac %g2, %g3, %g1 + cas [[%g2]], %g3, %g1],, + [AC_DEFINE(HAVE_AS_LEON, 1, + [Define if your assembler supports LEON instructions.])]) ;; changequote(,)dnl -- cgit v1.2.1
