2005-11-17 H.J. Lu <hongjiu.lu@intel.com> PR target/24879 * config/i386/i386.c (ix86_init_mmx_sse_builtins): Add void_ftype_di_di and void_ftype_pcvoid_di_di. Use void_ftype_di_di on __builtin_ia32_mwait and void_ftype_pcvoid_di_di on __builtin_ia32_monitor for 64bit. (ix86_expand_builtin): Support 64bit monitor and mwait. * config/i386/pmmintrin.h (_mm_monitor): Remove macro. Use inline function. (_mm_mwait): Likewise. * config/i386/sse.md (sse3_mwait): Make it 32bit only. (sse3_mwait64): New. 64bit mwait. (sse3_monitor): Make it 32bit only. (sse3_monitor64): New. 64bit monitor. gcc/testsuite/ 2005-11-17 H.J. Lu <hongjiu.lu@intel.com> PR target/24879 * gcc.target/i386/monitor.c: New file.
