* Convert more tools code from cerr and cout to errs() and outs().Dan Gohman2009-07-161-30/+28

* Begin the painful process of tearing apart the rat'ss nest that is ↵Owen Anderson2009-07-131-1/+2
| | | | | | | | | Constants.cpp and ConstantFold.cpp. This involves temporarily hard wiring some parts to use the global context. This isn't ideal, but it's the only way I could figure out to make this process vaguely incremental. llvm-svn: 75445
* Add a pointer to the owning LLVMContext to Module. This requires threading ↵Owen Anderson2009-07-011-1/+1
| | | | | | | | | | LLVMContext through a lot of the bitcode reader and ASM parser APIs, as well as supporting it in all of the tools. Patches for Clang and LLVM-GCC to follow. llvm-svn: 74614
* Fix the crash debugger to actually bisect globals once it's determined that itNick Lewycky2009-05-251-1/+1

* Add a bisection step on the list of instructions before doing the linearNick Lewycky2009-05-251-0/+92
| | | | | | | simplification. It's not clear to me whether this can replace the first of the linear instruction simplification stages or not, so I left it in. llvm-svn: 72377
* Make bugpoint emit a bugpoint-reduced-blocks.bc, because bugpoint itselfTorok Edwin2009-05-241-0/+3
| | | | | | | can crash during instruction simplification (for example if it creates a broken module). llvm-svn: 72362
* Add -disable-global-remove option to bugpoint.Torok Edwin2009-05-241-1/+6
| | | | | | | | | Sometimes when bugpointing a crash the bugpoint-reduced-simplified.bc reproduces a totally different bug than the original one ("GV doesn't have initializer"). Although its useful to report that bug too, I need a way to reduce the original bug, hence I introduced -disable-global-remove. llvm-svn: 72361
* CloneModule stores the BasicBlock mapping in ValueMap. There's no need toNick Lewycky2009-04-041-17/+6

* Use CloneModule's ValueMap to avoid needing to look upDan Gohman2009-03-061-5/+4
| | | | | | functions by name. This fixes PR718. llvm-svn: 66239
* Fix a bugpoint bug on anonymous functions. Instead of looking upDan Gohman2009-03-051-2/+4
| | | | | | | functions in the new module by name, use the ValueMap provided by CloneModule to do the lookups. llvm-svn: 66216

* For PR411:Reid Spencer2007-02-051-8/+9
| | | | | | | | | | This patch replaces the SymbolTable class with ValueSymbolTable which does not support types planes. This means that all symbol names in LLVM must now be unique. The patch addresses the necessary changes to deal with this and removes code no longer needed as a result. This completes the bulk of the changes for this PR. Some cleanup patches will follow. llvm-svn: 33918
* For PR1136: Rename GlobalVariable::isExternal as isDeclaration to avoidReid Spencer2007-01-301-3/+3
| | | | | | confusion with external linkage types. llvm-svn: 33663
* For PR411:Reid Spencer2007-01-061-1/+1
| | | | | | | | | Take an incremental step towards type plane elimination. This change separates types from values in the symbol tables by finally making use of the TypeSymbolTable class. This yields more natural interfaces for dealing with types and unclutters the SymbolTable class. llvm-svn: 32956
* For PR786:Reid Spencer2006-11-021-1/+0
| | | | | | | | | | Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting fall out by removing unused variables. Remaining warnings have to do with unused functions (I didn't want to delete code without review) and unused variables in generated code. Maintainers should clean up the remaining issues when they see them. All changes pass DejaGnu tests and Olden. llvm-svn: 31380

| | | | | | | initializers as well. This is only a first pass. It can be slow because it clones the module for each pass. An obvious improvement is not to do that. llvm-svn: 31182
* This commit adds a new feature called find-bugs. The find-bugs option can be ↵Patrick Jenkins2006-08-151-2/+2
| | | | | | invoked on a .bc file from the command like with -find-bugs and a list of passes you wish to test. This procedure takes the set of optimization passes the user specifies, randomizes the passes, runs the passes on the specified .bc file, compiles the program, and finally runs the program checking its output vs the .bc file with no optimizations. This process repeats until either the user kills bugpoint or an error occurs in the optimizations, program complitation, or the running of the program. If an error occurs, bugpoint attempts to diagnose the error by eliminating passes that are not at fault and code that is not needed. llvm-svn: 29703

* Final Changes For PR495:Reid Spencer2005-07-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This chagne just renames some sys::Path methods to ensure they are not misused. The Path documentation now divides methods into two dimensions: Path/Disk and accessor/mutator. Path accessors and mutators only operate on the Path object itself without making any disk accesses. Disk accessors and mutators will also access or modify the file system. Because of the potentially destructive nature of disk mutators, it was decided that all such methods should end in the work "Disk" to ensure the user recognizes that the change will occur on the file system. This patch makes that change. The method name changes are: makeReadable -> makeReadableOnDisk makeWriteable -> makeWriteableOnDisk makeExecutable -> makeExecutableOnDisk setStatusInfo -> setStatusInfoOnDisk createDirectory -> createDirectoryOnDisk createFile -> createFileOnDisk createTemporaryFile -> createTemporaryFileOnDisk destroy -> eraseFromDisk rename -> renamePathOnDisk These changes pass the Linux Deja Gnu tests. llvm-svn: 22354
* For PR495:Reid Spencer2005-07-071-2/+2
| | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 22349
