* [NewPM] teach -passes= to emit meaningful error messagesFedor Sergeev2018-10-171-5/+6
| | | | | | | | | | | | | | All the PassBuilder::parse interfaces now return descriptive StringError instead of a plain bool. It allows to make -passes/aa-pipeline parsing errors context-specific and thus less confusing. TODO: ideally we should also make suggestions for misspelled pass names, but that requires some extensions to PassBuilder.

| | | | | | This reverts r344519 due to failures in pipeline-parsing test. llvm-svn: 344524

* [AggressiveInstCombine] Add library initializer routine for ↵Craig Topper2018-04-241-0/+1
| | | | | | | | AggressiveInstCombine library. Use it in bugpoint and llvm-opt-fuzzer to match regular InstCombine. This should make aggressive instcombine usable with these tools. llvm-svn: 330663
* Rename *CommandFlags.def to *CommandFlags.incDavid Blaikie2018-04-111-1/+1
| | | | | | | | These aren't the .def style files used in LLVM that require a macro defined before their inclusion - they're just basic non-modular includes to stamp out command line flag variables. llvm-svn: 329840
* Pass a reference to a module to the bitcode writer.Rafael Espindola2018-02-141-1/+1
| | | | | | | This simplifies most callers as they are already using references or std::unique_ptr. llvm-svn: 325155

* Rename CommandFlags.h -> CommandFlags.defDavid Blaikie2017-11-271-1/+1
| | | | | | | | | Since this isn't a real header - it includes static functions and had external linkage variables (though this change makes them static, since that's what they should be) so can't be included more than once in a program. llvm-svn: 319082
* [FuzzMutate] NFC. Move parseModule and writeModule from llvm-isel-fuzzer ↵Igor Laevsky2017-11-161-36/+0
| | | | | | | | into FuzzMutate. This is to be able to reuse them in the llvm-opt-fuzzer. llvm-svn: 318407

* [llvm-opt-fuzzer] Introduce llvm-opt-fuzzer for fuzzing optimization passesIgor Laevsky2017-11-101-0/+259
This change adds generic fuzzing tools capable of running libFuzzer tests on any optimization pass or combination of them. Differential Revision: https://reviews.llvm.org/D39555 llvm-svn: 317883
