CHANGES:
Files:
 lib/CodeGen/PeepholeOptimizer.cpp
 lib/Target/ARM/ARMBaseInstrInfo.cpp
At: Tue 10 Aug 2010 14:40:37
Changed By: void
Comments: Turn optimize compares back on with fix. We needed to test that a machine op was
a register before checking if it was defined.
Properties: 




File: lib/Transforms/InstCombine/InstCombineVectorOps.cpp
At: Tue 10 Aug 2010 14:40:37
Changed By: sampo
Comments: Add the minimal amount of smarts necessary to instcombine of shufflevectors to recognize 
patterns generated by clang for transpose of a matrix in generic vectors.  This is made
of two parts:

1) Propagating vector extracts of hi/lo half into their users
2) Recognizing an insertion of even elements followed by the odd elements as an unpack.

Testcase to come, but this shrinks the # of shuffle instructions generated on x86 from ~40 to the minimal 8.
Properties:
