| * | Revert r128961 because it didn't include a test and causes the verifier to fail | Cameron Zwarich | 2011-05-19 | 1 | -5/+0 |
| | | | | | | | | | on CodeGen/X86/2007-05-07-InvokeSRet.ll. There is probably a bug here that was fixed by r128961, but since there is no test or reference to a source file I have to revert it. llvm-svn: 131618 | ||||
| * | Revert commit 131534 since it seems to have broken several buildbots. | Duncan Sands | 2011-05-18 | 3 | -4/+4 |

| | | | | | llvm-svn: 131524 | ||||
| * | Also use shrinkToUses after AdjustCopiesBackFrom(). | Jakob Stoklund Olesen | 2011-05-18 | 1 | -1/+1 |
| | | | | | | | | The 'last use' may not be in the same basic block, and we still want a correct live range. llvm-svn: 131523 | ||||
| * | Properly shrink live ranges after deleting dead copies. Clean up after all ↵ | Jakob Stoklund Olesen | 2011-05-18 | 1 | -24/+5 |
| | | | | | | | | | | | | | | joined copies. LiveInterval::shrinkToUses recomputes the live range from scratch instead of removing snippets. This should avoid the problem with dangling live ranges. Leave physreg identity copies alone. They can be created when joining a virtreg with a physreg. They don't affect register allocation, and they will be removed by the rewriter. llvm-svn: 131521 | ||||
| * | Make fast-isel miss counting in -stats and -fast-isel-verbose take ↵ | Eli Friedman | 2011-05-17 | 1 | -3/+8 |
| | | | | | | | terminators into account; since there are many fewer isel misses with recent changes, misses caused by terminators are more significant. llvm-svn: 131502 | ||||

| * | Fix an obscure issue in X86_64 parameter passing: if a tiny byval is | Stuart Hastings | 2011-05-17 | 1 | -2/+6 |
| | | | | | | | | passed as the fifth parameter, insure it's passed correctly (in R9). rdar://problem/6920088 llvm-svn: 131467 | ||||
| * | Tweak cross-class coalescing to be more aggressive when the target class is ↵ | Jakob Stoklund Olesen | 2011-05-17 | 1 | -3/+9 |
| | | | | | | | | | | | | | | small. The greedy register allocator has live range splitting and register class inflation, so it can actually fully undo this join, including restoring the original register classes. We still don't want to do this for long live ranges, mostly because of the high register pressure of there are many constrained live ranges overlapping. llvm-svn: 131466 | ||||
| * | Teach LiveInterval::isZeroLength about null SlotIndexes. | Jakob Stoklund Olesen | 2011-05-16 | 1 | -1/+1 |
| | | | | | | | | | | | | | 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. llvm-svn: 131436 | ||||

| * | Track how many insns fast-isel successfully selects as well as how many it | Jim Grosbach | 2011-05-16 | 1 | -0/+2 |

| * | Non-fast-isel followup to 129634; correctly handle branches controlled | Stuart Hastings | 2011-05-12 | 1 | -2/+9 |
| | | | | | | | | | | | | | | 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 llvm-svn: 131261 | ||||
