Committed by: vektor

Update of /cvs/xserver/xserver
In directory gabe:/tmp/cvs-serv8004

Modified Files:
	ChangeLog configure.ac 
Log Message:
	Bug #4414, reviewed by otaylor, cworth.

	* configure.ac: Remove -msse from the MMX CFLAGS as it causes
	gcc to emit SSE instructions, however the detection code only
	checks for processors supporting MMX and does not require SSE.
	Fix the MMX test to only check for MMX intrinsics and not the
	SSE intrinsics.
	* fb/fbmmx.c: Remove CPU detection code, only include
	xmmintrin.h if USE_SSE is defined.
	* fb/fbpict.c (detectCPUFeatures), (fbHaveMMX): Move CPU
	detection code out of the MMX file and into the generic code to
	avoid compiling it with -mmmx and -msse.  Using these options
	causes gcc to use MMX and SSE instructions in the CPU detection
	code which causes SIGILLs on older processors.
