Chris Lattner dbab386e23 Fix a significant algorithm problem with the instcombine worklist. removing ... a value from the worklist required scanning the entire worklist to remove all entries. We now use a combination map+vector to prevent duplicates from happening and prevent the scan. This speeds up instcombine on a large file from the llvm-gcc bootstrap from 189.7s to 4.84s in a debug build and from 5.04s to 1.37s in a release build. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34848 91177308-0d34-0410-b5e6-96231b3b80d8		2007-03-02 21:28:56 +00:00
