* [libFuzzer] Replace -seed_corpus to better support fork mode on WinJonathan Metzman2019-04-301-0/+5
| | | | | | | | | | | | | | | | | | Summary: Pass seed corpus list in a file to get around argument length limits on Windows. This limit was preventing many uses of fork mode on Windows.

* Use binary write mode in WriteToFile function to avoid appended \r ↵Vitaly Buka2019-04-051-1/+1
| | | | | | | | | | | | | | | | | | | | | characters on Windows Summary: When using libfuzzer on Windows, in the contents of a crash sample, bytes that can be mistaken for a \n are replaced by a \r\n sequence. As a consequence, crashes are not reproducible. This patch will open files in binary mode to fix this issue. The patch does not affect POSIX systems.

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@351636 91177308-0d34-0410-b5e6-96231b3b80d8

* [libFuzzer] Port to WindowsMatt Morehouse2018-08-301-8/+0
| | | | | | | | | | | | | | | | | | | | Summary: Port libFuzzer to windows-msvc. This patch allows libFuzzer targets to be built and run on Windows, using -fsanitize=fuzzer and/or fsanitize=fuzzer-no-link. It allows these forms of coverage instrumentation to work on Windows as well. It does not fix all issues, such as those with -fsanitize-coverage=stack-depth, which is not usable on Windows as of this patch. It also does not fix any libFuzzer integration tests. Nearly all of them fail to compile, fixing them will come in a later patch, so libFuzzer tests are disabled on Windows until them.
