* This patch is a big refactoring of llvm-diff. It doesn't add new features, ↵Renato Golin2011-03-148-321/+452
| | | | | | but it re-organizes the old features, so I can insert the MetadataEngine to use the same infrastructure. llvm-svn: 127627

* Fix the msvs 2010 build.Michael J. Spencer2010-08-271-2/+8
| | | | | | | | | | | | | | The Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 16.00.30319.01 implements parts of C++0x based on the draft standard. An old version of the draft had a bug that makes std::pair<T1*, T2*>(something, 0) fail to compile. This is because the template<class U, class V> pair(U&& x, V&& y) constructor is selected, even though it later fails to implicitly convert U and V to frist_type and second_type. This has been fixed in n3090, but it seems that Microsoft is not going to update msvc. llvm-svn: 112257
* Check in a couple of changes that I apparently never committed:John McCall2010-08-242-3/+34
| | | | | | | | | - teach DifferenceEngine to unify successors of calls and invokes in certain circumstances - basic blocks actually don't have their own numbering; did that change? - add llvm-diff to the Makefile and CMake build systems llvm-svn: 111909
* Transcribe IRC to svn. Also don't print basic block names twice if they match.John McCall2010-07-291-9/+19
| | | | llvm-svn: 109787
* Make the header self-contained and follow #include guidelines.John McCall2010-07-293-43/+52
| | | | llvm-svn: 109774
* Switch to using the LLVM CommandLine library so that our helpJohn McCall2010-07-291-39/+31
| | | | | | | message is properly contaminated with nonsense about timing passes that doesn't apply at all to this utility. :) llvm-svn: 109769
* Centralize the logic to permanently unify two instructions and make sureJohn McCall2010-07-291-20/+30
| | | | | | | it establishes a context and does a complaining diff. Also make sure we unify the prelude and postlude of a diff after a block-diff call. llvm-svn: 109744
* Diagnose non-structural differences in the case where blocks wereJohn McCall2010-07-291-5/+16
| | | | | | structurally identical. llvm-svn: 109743
* When unifying instructions during a block diff, actually complain aboutJohn McCall2010-07-291-1/+1
| | | | | | | | any differences we see. This should only happen if there are "non-structural" differences between the instructions, i.e. differences which wouldn't cause diff to return true. llvm-svn: 109742
* Somehow I was getting reasonable results for the test cases I was interestedJohn McCall2010-07-291-14/+38
| | | | | | | | | | | in despite not ever incrementing any path costs, so that the only nonzero costs arose from the all-left path in the first column. Anyway. Perform the diff starting from the beginning of the block to avoid capturing (say) loads of allocas. Vastly improves diff results on code that hasn't been mem2reg'ed. llvm-svn: 109741
* Cache the result of errs() and implement formatted logging.John McCall2010-07-292-37/+58

* Add the llvm-diff tool, which performs a relatively naive structuralJohn McCall2010-07-295-0/+1095
diff of a function. There's a lot of cruft in the current version, and it's pretty far from perfect, but it's usable. Currently only capable of comparing functions. Currently ignores metadata. Currently ignores most attributes of functions and instructions. Patches welcome. llvm-svn: 109739
