Evan Cheng dd487d865b More logical ops patterns 
llvm-svn: 27257

llvm-svn: 27255
 2006-03-30 00:33:26 +00:00
Evan Cheng c5cf9bba05 Change SSE pack operation definitions to fit what the intrinsics expected. 
For example, packsswb actually creates a v16i8 from a pair of v8i16. But since
the intrinsic specification forces the output type to match the operands.

llvm-svn: 27254
 2006-03-29 23:53:14 +00:00
Evan Cheng b7fedffc78 - Added some SSE2 128-bit packed integer ops. 
- Added SSE2 128-bit integer pack with signed saturation ops.

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

llvm-svn: 27250
 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.

llvm-svn: 27167
 2006-03-27 07:00:16 +00:00
Nate Begeman ed728c1291 SelectionDAGISel can now natively handle Switch instructions, in the same 
manner that the LowerSwitch LLVM to LLVM pass does: emitting a binary
search tree of basic blocks.  The new approach has several advantages:
it is faster, it generates significantly smaller code in many cases, and
it paves the way for implementing dense switch tables as a jump table by
handling switches directly in the instruction selector.

This functionality is currently only enabled on x86, but should be safe for
every target.  In anticipation of making it the default, the cfg is now
properly updated in the x86, ppc, and sparc select lowering code.

Evan Cheng 6dc73297c3 MEMSET / MEMCPY lowering bugs: we can't issue a single WORD / DWORD version of 
rep/stos and rep/mov if the count is not a constant. We could do
  rep/stosl; and $count, 3; rep/stosb
For now, I will lower them to memset / memcpy calls. We will revisit this after
a little bit experiment.

Also need to take care of the trailing bytes even if the count is a constant.
Since the max. number of trailing bytes are 3, we will simply issue loads /
stores.

  selection in CodeGenMap. These nodes should be safe to duplicate. This is

Evan Cheng 24c461b51e 1. Use pxor instead of xoraps / xorapd to clear FR32 / FR64 registers. This 
proves to be worth 20% on Ptrdist/ks. Might be related to dependency
   breaking support.
2. Added FsMOVAPSrr and FsMOVAPDrr as aliases to MOVAPSrr and MOVAPDrr. These
   are used for FR32 / FR64 reg-to-reg copies.
3. Tell reg-allocator to generate MOVSSrm / MOVSDrm and MOVSSmr / MOVSDmr to

Evan Cheng ae82498e81 Use movaps / movapd (instead of movss / movsd) to do FR32 / FR64 reg to reg 
transfer.

According to the Intel P4 Optimization Manual:

Moves that write a portion of a register can introduce unwanted
dependences. The movsd reg, reg instruction writes only the bottom
64 bits of a register, not to all 128 bits. This introduces a dependence on
the preceding instruction that produces the upper 64 bits (even if those
bits are not longer wanted). The dependence inhibits register renaming,
and thereby reduces parallelism.

Not to mention movaps is shorter than movss.

 2006-02-01 06:40:32 +00:00
Evan Cheng 9e350cd6ad - Use xor to clear integer registers (set R, 0). 
- Added a new format for instructions where the source register is implied
  and it is same as the destination register. Used for pseudo instructions
  that clear the destination register.

Evan Cheng a24617f5d4 Return's chain should be matching either the chain produced by the 
value or the chain going into the load.

Evan Cheng e1ce4d7115 When folding a load into a return of SSE value, check the chain to 
ensure the memory location has not been clobbered.

Evan Cheng 5659ca8f47 Be smarter about whether to store the SSE return value in memory. If 
it is already available in memory, do a fld directly from there.

Evan Cheng 72d5c256c9 - Allow XMM load (for scalar use) to be folded into ANDP* and XORP*. 
- Use XORP* to implement fneg.

 2006-01-31 00:20:38 +00:00
Evan Cheng 45df7f84ff Don't generate complex sequence for SETOLE, SETOLT, SETULT, and SETUGT. Flip 
the order of the compare operands and generate SETOGT, SETOGE, SETUGE, and
SETULE instead.

llvm-svn: 25818
 2006-01-30 22:13:22 +00:00
Evan Cheng 5b97fcf0f5 Always use FP stack instructions to perform i64 to f64 as well as f64 to i64 
conversions. SSE does not have instructions to handle these tasks.
