2003-10-05There is no need for separate WriteSets and PhiNodeBlocks lists. It is just aChris Lattner
work-list of value definitions. This allows elimination of the explicit 'iterative' step of the algorithm, and also reuses temporary memory better. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8861 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-05The PhiNodes 2D vector is only used during PHI node placement. It doesn'tChris Lattner
need to be an instance variable! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8860 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-05* Document instance vars betterChris Lattner
* Fuse two parallel loops * Use a more specific type for AllocaLookup git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8859 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-05Two small cleanups/speedups:Chris Lattner
* Do not insert a new entry into NewPhiNodes during the rename pass if there are no PHIs in a block. * Do not compute WriteSets in parallel git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8858 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-05* Minor cleanupsChris Lattner
* Eliminate the KillList instance variable, instead, just delete loads and stores as they are "renamed", and delete allocas when they are done * Make the 'visited' set an instance variable to avoid passing it on the stack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8857 91177308-0d34-0410-b5e6-96231b3b80d8

2003-04-10* Fix bug: Mem2Reg/2003-04-10-DFNotFound.llChris Lattner
* Make Mem2Reg assign version numbers now for renamed variables instead of .mem2reg suffixes. This produces what people think of as SSA. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5771 91177308-0d34-0410-b5e6-96231b3b80d8

2003-02-22Split mem2reg promotion into two parts: a function which does the work, andChris Lattner
a pass which wraps the function. This allows other passes to use the functionality git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5610 91177308-0d34-0410-b5e6-96231b3b80d8

2002-04-27* Rename MethodPass class to FunctionPassChris Lattner
- Rename runOnMethod to runOnFunction * Transform getAnalysisUsageInfo into getAnalysisUsage - Method is now const - It now takes one AnalysisUsage object to fill in instead of 3 vectors to fill in - Pass's now specify which other passes they _preserve_ not which ones they modify (be conservative!) - A pass can specify that it preserves all analyses (because it never modifies the underlying program) * s/Method/Function/g in other random places as well git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2333 91177308-0d34-0410-b5e6-96231b3b80d8
