* Fix a really nasty bug from my changes on Monday to PHIElim. These changesChris Lattner2004-05-121-11/+19
| | | | | | | | | broke obsequi and a lot of other things. It all boiled down to MBB being overloaded in an inner scope and me confusing it with the one in the outer scope. Ugh! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13517 91177308-0d34-0410-b5e6-96231b3b80d8
* Start NextMBBNumber out at zero.Brian Gaeke2004-05-121-1/+1
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13515 91177308-0d34-0410-b5e6-96231b3b80d8
* Add non-const MachineBasicBlock::getParent() accessor method.Brian Gaeke2004-05-121-0/+19
| | | | | | | | | MBBs start out as #-1. When a MBB is added to a MachineFunction, it gets the next available unique MBB number. If it is removed from a MachineFunction, it goes back to being #-1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13514 91177308-0d34-0410-b5e6-96231b3b80d8
* Switch this from using an std::map to using a DenseMap. This speeds upChris Lattner2004-05-101-6/+5
| | | | | | | phi-elimination from 0.6 to 0.54s on kc++. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13454 91177308-0d34-0410-b5e6-96231b3b80d8
* Use a new VRegPHIUseCount to compute uses of PHI values by other phi valuesChris Lattner2004-05-101-14/+21
| | | | | | | | in the basic block being processed. This fixes PhiElimination on kimwitu++ from taking 105s to taking a much more reasonable 0.6s (in a debug build). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13453 91177308-0d34-0410-b5e6-96231b3b80d8
* Now that we use an ilist of machine instructions, iterators are more robustChris Lattner2004-05-101-5/+8
| | | | | | | | | | than before. Because this is the case, we can compute the first non-phi instruction once when de-phi'ing a block. This shaves ~4s off of phielimination of _Z7yyparsev in kimwitu++ from 109s -> 105s. There are still much more important gains to come. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13452 91177308-0d34-0410-b5e6-96231b3b80d8
* Patch to fix PR337. Make sure to mark all aliased physical registers as usedChris Lattner2004-05-101-3/+8
| | | | | | | | | | | | | | when we see a read of a register. This is important in cases like: AL = ... AH = ... = AX The read of AX must make both the AL and AH defs live until the use. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13444 91177308-0d34-0410-b5e6-96231b3b80d8

* Stop LiveVariables from using BasicBlocks as part of the mapping, insteadChris Lattner2004-05-011-29/+20
| | | | | | | | | use MachineBasicBlocks. To do this, we traverse the Machine CFG instead of the LLVM CFG, which is also *MUCH* more efficient by having fewer levels of indirections and mappings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13301 91177308-0d34-0410-b5e6-96231b3b80d8
