2011-05-18In r131488 I misunderstood how VREV works. It splits the vector in half and ↵Tanya Lattner
splits each half. Therefore, the real problem was that we were using a VREV64 for a 4xi16, when we should have been using a VREV32. Updated test case and reverted change to the PerfectShuffle Table. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131529 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-16Teach LiveInterval::isZeroLength about null SlotIndexes.Jakob Stoklund Olesen
When instructions are deleted, they leave tombstone SlotIndex entries. The isZeroLength method should ignore these null indexes. This causes RABasic to sometimes spill a callee-saved register in the abi-isel.ll test, so don't run that test with -regalloc=basic. Prioritizing register allocation according to spill weight can cause more registers to be used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131436 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-12Non-fast-isel followup to 129634; correctly handle branches controlledStuart Hastings
by non-CMP expressions. The executable test case (129821) would test this as well, if we had an "-O0 -disable-arm-fast-isel" LLVM-GCC tester. Alas, the ARM assembly would be very difficult to check with FileCheck. The thumb2-cbnz.ll test is affected; it generates larger code (tst.w vs. cmp #0), but I believe the new version is correct. rdar://problem/9298790 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131261 91177308-0d34-0410-b5e6-96231b3b80d8
