* [FuzzMutate] Fix windows build after rL318407.Igor Laevsky2017-11-161-1/+1
| | | | | | Add correct library dependence. llvm-svn: 318409
* [FuzzMutate] NFC. Move parseModule and writeModule from llvm-isel-fuzzer ↵Igor Laevsky2017-11-161-0/+36
| | | | | | | | 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/+34
| | | | | | | | | 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
* FuzzMutate: Fix arch parsing in FuzzerCLIJustin Bogner2017-10-171-1/+1
| | | | | | | | The right way to parse arch names is by creating a triple. This was using getArchTypeForLLVMName before, which doesn't really do the right thing here. llvm-svn: 315965
* [llvm-isel-fuzzer] Use "--" as separator rather than '='.Matt Morehouse2017-10-131-1/+1
| | | | | | | | | | | | | | Summary: OSS-Fuzz doesn't support '=' in filenames. Reviewers: bogner, kcc Reviewed By: kcc Subscribers: javed.absar, hiraditya, llvm-commits Differential Revision: https://reviews.llvm.org/D38866 llvm-svn: 315647
* Re-commit "llvm-isel-fuzzer: Handle a subset of backend flags in the exec name"Justin Bogner2017-10-121-1/+37
| | | | | | | | | | | | | | | | | | Here we add a secondary option parser to llvm-isel-fuzzer (and provide it for use with other fuzzers). With this, you can copy the fuzzer to a name like llvm-isel-fuzzer=aarch64-gisel for a fuzzer that fuzzer AArch64 with GlobalISel enabled, or fuzzer=x86_64 to fuzz x86, with no flags required. This should be useful for running these in OSS-Fuzz. Note that this handrolls a subset of cl::opts to recognize, rather than embedding a complete command parser for argv[0]. If we find we really need the flexibility of handling arbitrary options at some point we can rethink this. This re-applies 315545 using "=" instead of ":" as a separator for arguments. llvm-svn: 315557

* Move some CLI utils out of llvm-isel-fuzzer and into the libraryJustin Bogner2017-09-022-0/+64
| | | | | | | | FuzzMutate might not be the best place for these, but it makes more sense than an entirely new library for now. This will make setting up fuzz targets with consistent CLI handling easier. llvm-svn: 312425
* Re-apply "Introduce FuzzMutate library"Justin Bogner2017-08-216-0/+707
| | | | | | | | | | | | | | Same as r311392 with some fixes for library dependencies. Thanks to Chapuni for helping work those out! Original commit message: This introduces the FuzzMutate library, which provides structured fuzzing for LLVM IR, as described in my EuroLLVM 2017 talk. Most of the basic mutators to inject and delete IR are provided, with support for most basic operations. llvm-svn: 311402
* Revert "Re-apply "Introduce FuzzMutate library""Justin Bogner2017-08-216-707/+0
| | | | | | | | | | | The dependencies for the new library seem to be misconfigured on some linux configs: http://bb.pgr.jp/builders/llvm-i686-linux-RA/builds/5435/steps/build_all/logs/stdio This reverts r311392. llvm-svn: 311393
* Re-apply "Introduce FuzzMutate library"Justin Bogner2017-08-216-0/+707
| | | | | | | | | | | | | | | Redo r311356 with a fix to avoid std::uniform_int_distribution<bool>. The bool specialization is undefined according to the standard, even though libc++ seems to have it.

* Introduce FuzzMutate libraryJustin Bogner2017-08-216-0/+707
This introduces the FuzzMutate library, which provides structured fuzzing for LLVM IR, as described in my [EuroLLVM 2017 talk][1]. Most of the basic mutators to inject and delete IR are provided, with support for most basic operations. I will follow up with the instruction selection fuzzer, which is implemented in terms of this library. [1]: http://llvm.org/devmtg/2017-03//2017/02/20/accepted-sessions.html#2 llvm-svn: 311356
