Subject: [PATCH] x86 : LDMXCSR/STMXCSR are SSE, not MMX

Hi,

LDMXCSR and STMXCSR are SSE instructions, not MMX.
With the attached patch, the corresponding builtins (__builtin_ia32_ldmxcsr
and __builtin_ia32_stmxcsr) are rejected when SSE is not supported.


2002-11-27  Sylvain Pion <Sylvain.Pion@mpi-sb.mpg.de>

	* config/i386/i386.c (ix86_init_mmx_sse_builtins):
	__builtin_ia32_ldmxcsr and __builtin_ia32_stmxcsr are SSE, not MXX.
	* config/i386/i386.md (ldmxcsr, stmxcsr): SSE, not MMX.
