* 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] [Windows] Include windows.h and psapi.h with lowercaseMartin Storsjo2018-09-111-1/+1
| | | | | | | | | | | | | This fixes building on a case sensitive filesystem with mingw-w64 headers, where all headers are lowercase, and matches how these headers are included elsewhere in compiler-rt. Also include these headers with angle brackets, as they are system headers.

* [libFuzzer] Port to WindowsMatt Morehouse2018-08-301-1/+3
| | | | | | | | | | | | | | | | | | | | 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.

* [libFuzzer] Encapsulate commands in a class.Matt Morehouse2017-12-041-2/+4
| | | | | | | | | | | | | | | | | | | | | Summary: To be more portable (especially w.r.t. platforms without system()), commands should be managed programmatically rather than via string manipulation on the command line. This change introduces Fuzzer::Command, with methods to manage arguments and flags, set output options, and execute the command.
