Get rid of the difference between file paths and directory paths. The Path class now simply stores a path that can refer to either a file or a directory. This required various changes in the implementation and interface of the class with the corresponding impact to its users. Doxygen comments were also updated to reflect these changes. Interface changes are: appendDirectory -> appendComponent appendFile -> appendComponent elideDirectory -> eraseComponent elideFile -> eraseComponent elideSuffix -> eraseSuffix renameFile -> rename setDirectory -> set setFile -> set Changes pass Dejagnu and llvm-test/SingleSource tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22349 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-11Implement basic block extraction for the miscompilation debugger. This ↵Chris Lattner
still needs two things: the FIXME in ExtractBlocks needs to be implemented, and the basic block extractor itself needs to have enough bugs fixed for this to be more or less useful. Until the time that this is generally useful, it is hidden behind the new bugpoint -enable-block-extraction option. I hope to get the FIXME done tonight. Also of note, this patch adds a -extract-bbs option to bugpoint which can be used to debug the block extractor.

2004-04-19As per Chris, greatly simplify handling of external functions by using theMisha Brukman
wrapper idea uniformly: we can use Value::replaceAllUsesWith() instead of special-casing by class of user. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13063 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-19Finally implement rewriting global initializers which use external functionsMisha Brukman
by creating an internal wrapper function with same signature as the external function, and use it instead of the "real" function. The wrapper then calls the external function using the same JIT function resolution API that has been used before for rewriting instructions, since the wrapper has an explicit call instruction which we can rewrite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13054 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-02Fix two pretty serious bugs:Chris Lattner
1. Each time the loop extractor extracted a loop, we would leak a module. 2. When we extracted a loop, we didn't add the new function to the list of miscompiled functions. Thus if the bug was in a loop nest and we extracted it, we could actually *LOSE THE BUG*, which is very bad. With these patches, bugpoint has successfully found a bug for me in a function with several nested loops, and cut it down to just one of them. :) :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12605 91177308-0d34-0410-b5e6-96231b3b80d8
