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.

2004-04-02Fix a fairly nasty bug that prevented bugpoint from working quite right whenChris Lattner
hacking on programs with two functions that have the same name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12604 91177308-0d34-0410-b5e6-96231b3b80d8
2004-03-17Fix an inverted condition that causes us to think that loop extractionChris Lattner
accomplished something when it really did not. This does not fix the bigger problem tho. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12469 91177308-0d34-0410-b5e6-96231b3b80d8
2004-03-14After reducing a miscompiled program down to the functions which are beingChris Lattner
miscompiled, try to use the loop extractor to reduce the program down to a loop nest that is being miscompiled. In practice, the loop extractor appears to have too many bugs for this to be useful, but hopefully they will be fixed soon... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12398 91177308-0d34-0410-b5e6-96231b3b80d8

2004-03-14Refactor and clean up a bunch more code. No major functionality changes.Chris Lattner
* Make several methods of bugdriver global functions (ParseInputFile, PrintFunctionList) * Make PrintFunctionList truncate the output after 10 entries, like the crash debugger did. This allows code sharing. * Add a couple of methods to BugDriver that allows us to eliminate some friends * Improve comments in ExtractFunction.cpp * Make classes that used to be friends up bugdriver now live in anon namespaces * Rip a bunch of functionality in the miscompilation tester into a new TestMergedProgram function for future code sharing. * Fix a bug in the miscompilation tester induced in my last checkin git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12393 91177308-0d34-0410-b5e6-96231b3b80d8

2003-11-05I hate it when bugpoint is all ready to give me a bytecode file, then crashesChris Lattner
in final cleanups. Then you had to run the whole mess again with -disable-final-cleanups. This makes bugpoint run the cleanups in a protected environment so that if they crash, bugpoint itself doesn't crash. This makes things much happier, implements a FIXME, and gets rid of YABPO (yet another bugpoint option). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9743 91177308-0d34-0410-b5e6-96231b3b80d8
