Dale Johannesen	4d1ca2ab29	Mark all these as needing SSE2. Should fix PPC and ... maybe even Linux. llvm-svn: 115291	2010-10-01 04:17:55 +00:00
Dale Johannesen	c14a1eda84	Massive rewrite of MMX: ... The x86_mmx type is used for MMX intrinsics, parameters and return values where these use MMX registers, and is also supported in load, store, and bitcast. Only the above operations generate MMX instructions, and optimizations do not operate on or produce MMX intrinsics. MMX-sized vectors <2 x i32> etc. are lowered to XMM or split into smaller pieces. Optimizations may occur on these forms and the result casted back to x86_mmx, provided the result feeds into a previous existing x86_mmx operation. The point of all this is prevent optimizations from introducing MMX operations, which is unsafe due to the EMMS problem. llvm-svn: 115243	2010-09-30 23:57:10 +00:00
