2003-10-19Change the Opcode enum for PHI nodes from "Instruction::PHINode" to ↵Chris Lattner
"Instruction::PHI" to be more consistent with the other instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9269 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-13Make use of "external" depth-first iterators to avoid revisiting nodesChris Lattner
multiple times. This reduces the time to construct post-dominance sets a LOT. For example, optimizing perlbmk goes from taking 12.9894s to 1.4074s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9091 91177308-0d34-0410-b5e6-96231b3b80d8

2003-09-10Rework post dominator information so that we do not have toChris Lattner
unify all exit nodes of a function to compute post-dominance information. This does not work with functions that have both unwind and return nodes, because we cannot unify these blocks. The new implementation is better anyway. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8460 91177308-0d34-0410-b5e6-96231b3b80d8
