Eric Christopher	ab2802c58f	Update test to use FileCheck and clean up run lines to match the ... expected behavior. llvm-svn: 249498	2015-10-07 01:21:49 +00:00
Nadav Rotem	486ff59a9f	Enable element promotion type legalization by deafault. ... Changed tests which assumed that vectors are legalized by widening them. llvm-svn: 142152	2011-10-16 20:31:33 +00:00
Dale Johannesen	dd224d2333	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
Dan Gohman	40503396da	Eliminate more uses of llvm-as and llvm-dis. ... llvm-svn: 81290	2009-09-08 23:54:48 +00:00
Eli Friedman	a9c52c8219	Fix for PR2687: Add patterns to match sint_to_fp and fp_to_sint for <2 x ... i32>. This is a little messy, but it works. We should really get rid of the intrinsics, though, since they map perfectly well to standard LLVM instructions. llvm-svn: 55864	2008-09-05 23:07:03 +00:00
