Chris Lattner 2771e2c960 Codegen things like: 
<int -1, int -1, int -1, int -1>
and
 <int 65537, int 65537, int 65537, int 65537>

Using things like:
  vspltisb v0, -1
and:
  vspltish v0, 1

instead of using constant pool loads.

This implements CodeGen/PowerPC/vec_splat.ll:splat_imm_i{32|16}.

Chris Lattner d589dd1352 Fix a bad JIT encoding of VPERM. Why is VPERM D,A,B,C but vfmadd is D,A,C,B ?? 
llvm-svn: 27069
 2006-03-24 18:24:43 +00:00
Chris Lattner f2286d5917 Like the comment says, prefer to use the implicit add done by [r+r] addressing 
modes than emitting an explicit add and using a base of r0.  This implements
Regression/CodeGen/PowerPC/mem-rr-addr-mode.ll

llvm-svn: 27068
 2006-03-24 17:58:06 +00:00
Jim Laskey 864e444749 Clean up some commentary.

Chris Lattner a90b7141ed Disable the i32->float G5 optimization. It is unsafe, as documented in the 
comment.

This fixes 177.mesa, and McCat/09-vor with the td scheduler.

llvm-svn: 26980
 2006-03-23 07:44:07 +00:00
Chris Lattner 6f95ab7abb Eliminate IntrinsicLowering from TargetMachine. 
Make the CBE and V9 backends create their own, since they're the only ones that use it.

llvm-svn: 26974

Evan Cheng bc04722860 Some clean up. 
llvm-svn: 26957
 2006-03-22 19:22:18 +00:00
Evan Cheng d4e1557941 - Supposely movlhps is faster / better than unpcklpd. 
- Don't forget pshufd is only available with sse2.

llvm-svn: 26956
 2006-03-22 19:16:21 +00:00
Evan Cheng 68ad48bd1a - Implement X86ISelLowering::isShuffleMaskLegal(). We currently only support 
splat and PSHUFD cases.
- Clean up shuffle / splat matching code.

llvm-svn: 26954
 2006-03-22 18:59:22 +00:00
Evan Cheng 8fdbdf20cd - VECTOR_SHUFFLE of v4i32 / v4f32 with undef second vector always matches 
PSHUFD. We can make permutes entries which point to the undef pointing
  anything we want.
- Change some names to appease Chris.
