Evan Cheng acc336475e Need to special case splat after all. Make the second operand of splat 
vector_shuffle undef.

 2006-03-29 19:02:40 +00:00
Evan Cheng 3cf95747c7 Floating point logical operation patterns should match bit_convert. Or else 
integer vector logical operations would match andp{s|d} instead of pand.

Evan Cheng 500ec16578 - More shuffle related bug fixes. 
- Whenever possible use ops of the right packed types for vector shuffles /
  splats.

Evan Cheng da59b0d2a8 - Only use pshufd for v4i32 vector shuffles. 
- Other shuffle related fixes.

 2006-03-29 01:30:51 +00:00
Evan Cheng 38b34296d0 Added aliases to scalar SSE instructions, e.g. addss, to match x86 intrinsics. 
The source operands type are v4sf with upper bits passes through.
Added matching code for these.

* Bug fixes.

 2006-03-22 19:16:21 +00:00
Evan Cheng 68ad48bd1a - Implement X86ISelLowering::isShuffleMaskLegal(). We currently only support 
splat and PSHUFD cases.

and MOVAPD. Mark them as move instructions and *hope* they will be deleted.
