Evan Cheng 25e44e008d Rename instructions for consistency sake. 
llvm-svn: 28594
 2006-05-31 19:00:07 +00:00
Evan Cheng 8abf45e22d Select vector_shuffle v1, undef <2, 3, ?, ?> to MOVHLPS.

Evan Cheng 57399704b3 MAXP{D|S} and MINP{D|S} are commutable.

Evan Cheng c0f90bef47 Commute shufps / shufpd. 
llvm-svn: 28577
 2006-05-30 23:34:30 +00:00
Evan Cheng 66f849bd7b Allow shufps x, x, mask to be converted to pshufd x, mask to save a move.

 2006-05-30 20:26:50 +00:00
Evan Cheng 9fee442e63 X86 integer register classes naming changes. Make them consistent with FP, vector classes.

Chris Lattner 44a73e9fa5 Teach the code generator to use cvtss2sd as extload f32 -> f64 
llvm-svn: 28131
 2006-05-05 21:35:18 +00:00
Evan Cheng 8b1cde2bbe Use movsd to shuffle in the lowest two elements of a v4f32 / v4i32 vector when 
movlps cannot be used (e.g. when load from m64 has multiple uses).

llvm-svn: 28089
 2006-05-03 20:32:03 +00:00
Evan Cheng 4cc3e0b05f Fix a typo. 
llvm-svn: 27968
 2006-04-25 17:48:41 +00:00
Evan Cheng fb46b2bf5d Explicitly specify result type for def : Pat<> patterns (if it produces a vector 
result). Otherwise tblgen will pick the default (v16i8 for 128-bit vector).

llvm-svn: 27965
 2006-04-25 00:50:01 +00:00
Evan Cheng 25b09295f8 Added X86 SSE2 intrinsics which can be represented as vector_shuffles. This is 
a temporary workaround for the 2-wide vector_shuffle problem (i.e. its mask
would have type v2i32 which is not legal).

llvm-svn: 27964
 2006-04-24 23:34:56 +00:00
Evan Cheng 63bd4d3730 Some missing movlps, movhps, movlpd, and movhpd patterns. 
llvm-svn: 27960
 2006-04-24 21:58:20 +00:00
Evan Cheng e8b5180044 Now generating perfect (I think) code for "vector set" with a single non-zero 
scalar value.

e.g.
        _mm_set_epi32(0, a, 0, 0);
==>
	movd 4(%esp), %xmm0
	pshufd $69, %xmm0, %xmm0

        _mm_set_epi8(0, 0, 0, 0, 0, a, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0);
==>
	movzbw 4(%esp), %ax
	movzwl %ax, %eax
	pxor %xmm0, %xmm0
	pinsrw $5, %eax, %xmm0

Evan Cheng 6d5297dac3 Prefer {p}unpack* and mov*dup over {p}shuf* as well. 
llvm-svn: 27844
 2006-04-19 21:15:24 +00:00
Evan Cheng b416a25174 - Renamed AddedCost to AddedComplexity. 
- Added more movhlps and movlhps patterns.

llvm-svn: 27842
 2006-04-19 20:37:34 +00:00
Evan Cheng cc7abc6c38 More mov{h|l}p{d|s} patterns. 
llvm-svn: 27836
 2006-04-19 18:20:17 +00:00
Evan Cheng aeb09ccdd3 - More mov{h|l}ps patterns. 
- Increase cost (complexity) of patterns which match mov{h|l}ps ops. These
  are preferred over shufps in most cases.

llvm-svn: 27835
 2006-04-19 18:11:52 +00:00
Evan Cheng 3823aa1d0f - PEXTRW cannot take a memory location as its first source operand.
