Matt Arsenault 1f521e921d Scalarize select vector arguments when extracted.
When the elements are extracted from a select on vectors
or a vector select, do the select on the extracted scalars
from the input if there is only one use.

InstCombine.h InstCombine: Remove unused argument. No functionality change. 2013-09-20 22:12:42 +00:00
InstCombineAddSub.cpp Preserve fast-math flags when folding (fsub x, (fneg y)) to (fadd x, y). 2013-07-30 23:53:17 +00:00
InstCombineAndOrXor.cpp InstCombine: allow unmasked icmps to be combined with logical ops 2013-09-04 11:57:17 +00:00
InstCombineCalls.cpp Use type helper functions 2013-09-27 22:18:51 +00:00
InstCombineCasts.cpp Pull fptrunc's upwards through selects when one of the select's selectands was a constant. This has a number of benefits, including producing small immediates (easier to materialize, smaller constant pools) as well as being more likely to allow the fptrunc to fuse with a preceding instruction (truncating selects are unusual). 2013-10-03 21:08:05 +00:00
InstCombineCompares.cpp Use right address space size in InstCombineCompares 2013-09-30 21:11:01 +00:00
InstCombineLoadStoreAlloca.cpp InstCombine: Don't allow turning vector-of-pointer loads into vector-of-integer. 2013-09-19 20:59:04 +00:00
InstCombineMulDivRem.cpp InstCombine: Replace manual fast math flag copying with the new IRBuilder RAII helper. 2013-09-30 15:39:59 +00:00
InstCombinePHI.cpp Push analysis passes to InstSimplify when they're around anyways. 2013-09-24 16:37:40 +00:00
InstCombineSelect.cpp InstCombine: Only foldSelectICmpAndOr for integer types 2013-09-27 20:35:39 +00:00
InstCombineShifts.cpp
InstCombineSimplifyDemanded.cpp Remove x86_sse42_crc32_64_8 intrinsic. It has no functional difference from x86_sse42_crc32_32_8 and was not mapped to a clang builtin. I'm not even sure why this form of the instruction is even called out explicitly in the docs. Also add AutoUpgrade support to convert it into the other intrinsic with appropriate trunc and zext. 2013-10-15 05:20:47 +00:00
InstCombineVectorOps.cpp Scalarize select vector arguments when extracted. 2013-11-04 20:36:06 +00:00
InstCombineWorklist.h Consistently use dbgs() in debug printing 2013-09-05 19:48:28 +00:00
InstructionCombining.cpp Make gep i8* X, -(ptrtoint Y) transform work with address spaces 2013-10-03 18:15:57 +00:00
