Chris Lattner ce0206e119 Fix the encodings of these new instructions, hopefully fixing the JIT 
failures from last night

llvm-svn: 26981
 2006-03-23 16:13:50 +00:00
Evan Cheng 82ed4a42f9 Following icc's lead: use movdqa to load / store 128-bit integer vectors 
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
 2006-03-23 05:43:16 +00:00
Evan Cheng 7055878170 Add v4i32 <-> v4f32 bitconvert patterns.

llvm-svn: 26966
 2006-03-23 01:29:48 +00:00
Evan Cheng 021bb7c956 Added a ValueType operand to isShuffleMaskLegal(). For now, x86 will not do 
64-bit vector shuffle.

llvm-svn: 26964
 2006-03-22 22:07:06 +00:00
Evan Cheng ed794cd27b SHUFP* are two address code.

 2006-03-22 20:08:18 +00:00
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.

llvm-svn: 26951
 2006-03-22 08:01:21 +00:00

llvm-svn: 26933
 2006-03-21 23:04:23 +00:00
Evan Cheng d5e905d762 - Use movaps to store 128-bit vector integers. 
- Each scalar to vector v8i16 and v16i8 is a any_extend followed by a movd.

llvm-svn: 26932
 2006-03-21 23:01:21 +00:00
Chris Lattner 00f4683bf6 These targets don't support EXTRACT_VECTOR_ELT, though, in time, X86 will. 
llvm-svn: 26930

llvm-svn: 26920
 2006-03-21 07:12:57 +00:00
Evan Cheng 1208d9179a - Remove scalar to vector pseudo ops. They are just wrong. 
- Handle FR32 to VR128:v4f32 and FR64 to VR128:v2f64 with aliases of MOVAPS
and MOVAPD. Mark them as move instructions and *hope* they will be deleted.

llvm-svn: 26919

V8I16, etc.

llvm-svn: 26838
 2006-03-18 01:23:20 +00:00
