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

2003-04-10Fixed 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

2003-03-31Initial checkin of PRE on LLVM. This implementation is still lacking inChris Lattner
several ways: * Load expressions are not PRE'd well. Alias Analysis should be used to get accurate information when computing anticipatibility. * The expression collection implementation does not handle PHI nodes properly, thus the implementation misses many opportunities to PRE. * This code could be sped up quite a bit Despite these flaws, the code seems to work well, and handles PR's as one would expect. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5759 91177308-0d34-0410-b5e6-96231b3b80d8

2003-03-19Changes to the V2 bytecode format:Chris Lattner
- Null values are implicitly encoded instead of explicitly, this makes things more compact! - More compactly represent ConstantPointerRefs - Bytecode files are represented as: Header|GlobalTypes|GlobalVars/Function Protos|Constants|Functions|SymTab instead of Header|GlobalTypes|Constants|GlobalVars/Function Protos|Functions|SymTab which makes a lot of things simpler. Writer changes: - We now explictly encode versioning information in the bytecode files. - This allows new code to read bytecode files produced by old code, but new bytecode files can have enhancements such as the above. Although this makes the reader a bit more complex (having to deal with old formats), the writer only needs to be able to produce the most recent version. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5749 91177308-0d34-0410-b5e6-96231b3b80d8
2003-03-19* Bug fixes:Chris Lattner
- Fix problems where the constant table would not get updated when resolving constants causes other constants to change. Changes to the V2 bytecode format - Null values are implicitly encoded instead of explicitly, this makes things more compact! - More compactly represent ConstantPointerRefs - Bytecode files are represented as: Header|GlobalTypes|GlobalVars/Function Protos|Constants|Functions|SymTab instead of Header|GlobalTypes|Constants|GlobalVars/Function Protos|Functions|SymTab which makes a lot of things simpler. Changes to the reader: - Function loading code is much simpler. We now no longer make function PlaceHolderHelper objects to be replaced with real functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5748 91177308-0d34-0410-b5e6-96231b3b80d8
