2003-05-12Use a kill, not a dead definition, update commentChris Lattner

2003-05-12* Keep LiveVariable information more up-to-date and consistentChris Lattner
* *** Finally mark values that are inputs to PHIs as killed when appropriate. This should make the generated code quite a bit better. For example, the local-ra will not have to spill PHI inputs at the end of predecessor BB's anymore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6117 91177308-0d34-0410-b5e6-96231b3b80d8

2003-05-12* Keep the BBMap around as long as the pass is liveChris Lattner
* Change getVarInfo to take real virtual register numbers and offset them itself. This has caused me so much grief, it's not even funny. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6115 91177308-0d34-0410-b5e6-96231b3b80d8

2003-04-22Just some code beautification changes I had sitting around in my tree.Misha Brukman

2003-04-10Fixed compilation errors, command-line argument declarations, cleaned up code toMisha Brukman
look nicer and removed useless stuff. Also renamed a few variables, moved them into namespaces, converted outputting to a file into a print to std::cerr with a DEBUG() guard, as all passes should do anyway. No functional changes have been made. However, this code now compiles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5769 91177308-0d34-0410-b5e6-96231b3b80d8
2003-04-09Made the code readable:Misha Brukman
* Lines must be wrapped at 80 chars. This is a hard limit. * Consistent style on functions, braces, if, for, etc. Code must be readable. No functional changes have been made, even though I added a new typedef. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5768 91177308-0d34-0410-b5e6-96231b3b80d8
