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	54ec4bfa5f	Change the x86 assembly output to use tab characters to separate the ... mnemonics from their operands instead of single spaces. This makes the assembly output a little more consistent with various other compilers (f.e. GCC), and slightly easier to read. Also, update the regression tests accordingly. llvm-svn: 40648	2007-07-31 20:11:57 +00:00
Bill Wendling	3053244b27	Allow a GR64 to be moved into an MMX register via the "movd" instruction. ... Still need to have JIT generate this code. llvm-svn: 37863	2007-07-04 00:19:54 +00:00
