Evan Cheng dddb688a40 An entry about comi / ucomi intrinsics.

Evan Cheng f3b52c84ea Handle canonical form of e.g. 
vector_shuffle v1, v1, <0, 4, 1, 5, 2, 6, 3, 7>

This is turned into
vector_shuffle v1, <undef>, <0, 0, 1, 1, 2, 2, 3, 3>
by dag combiner.

It would match a {p}unpckl on x86.

Evan Cheng 2cf4232ced Fallthrough to expand if a VECTOR_SHUFFLE cannot be custom lowered.

Chris Lattner 4a744e5c9d Fix some broken logic that would cause us to codegen {2147483647,2147483647,2147483647,2147483647} as 'vspltisb v0, -1'.

 2006-04-04 18:40:36 +00:00
Chris Lattner 4ea52cac01 Do not create ZEXTLOAD's unless we are before legalize or the operation is 
legal.

llvm-svn: 27402
 2006-04-04 17:39:18 +00:00
Chris Lattner 95c7adc7cb Ask legalize to promote all vector shuffles to be v16i8 instead of having to 
handle all 4 PPC vector types.   This simplifies the matching code and allows
us to eliminate a bunch of patterns.  This also adds cases we were missing,
such as CodeGen/PowerPC/vec_splat.ll:splat_h.

llvm-svn: 27400
 2006-04-04 17:25:31 +00:00
Chris Lattner 6be79823e7 * Add supprot for SCALAR_TO_VECTOR operations where the input needs to be 
promoted/expanded (e.g. SCALAR_TO_VECTOR from i8/i16 on PPC).
* Add support for targets to request that VECTOR_SHUFFLE nodes be promoted
  to a canonical type, for example, we only want v16i8 shuffles on PPC.
* Move isShuffleLegal out of TLI into Legalize.
* Teach isShuffleLegal to allow shuffles that need to be promoted.

more than the OS keeps the stack aligned.
