* [libFuzzer] add -features_dir= flag to dump unique input features on diskKostya Serebryany2019-04-131-0/+4

* [libFuzzer][Windows] Port fork mode to WindowsJonathan Metzman2019-02-271-6/+65
| | | | | | | | | | | | | | | | | | | | | Summary: Port libFuzzer's fork mode to Windows. Implement Windows versions of MkDir, RmDir, and IterateDirRecursive to do this. Don't print error messages under new normal uses of FileSize (on a non-existent file). Implement portable way of piping output to /dev/null. Fix test for Windows and comment fork-sigusr.test on why it won't be ported to Win.

| | | | | | | | | | | | | | | | Summary: Use `_write` instead of the deprecated alias `write` on Windows. Also, remove comment saying RawPrint is untested on Windows.

* [fuzzer] Use RawPrint instead of Printf for instrumentation warningJonathan Metzman2019-01-311-1/+1
| | | | | | | | | | | | | | | Summary: Use RawPrint instead of Printf for instrumentation warning because Printf doesn't work on Win when instrumentation is being initialized (since OutputFile is not yet initialized).

* 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] Enable tests on WindowsMatt Morehouse2018-09-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Enable tests on Windows and make check-fuzzer pass on it. Make check-fuzzer pass on Windows by fixing libFuzzer, fixing tests, and by disabling tests on Windows. Most of these are disabled temporarily as support for the tests and the features they test will be added incrementally. Other tests will not be enabled since they require things that are not on Windows (eg: afl_driver tests). Every test that was explicitly disabled on Windows has a comment explaining why (unless obvious like merge-posix.test). The lit.cfg file was modified to support running tests on windows. fuzzer-dirs.test was fixed by making the Windows implementation print the same error message as the posix version. merge-control-file.test was fixed by making the test binary end with the ".exe" extension (on all platforms).

* [libFuzzer] Port to WindowsMatt Morehouse2018-08-301-0/+20
| | | | | | | | | | | | | | | | | | | | 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.
