* 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
* Add weak definitions of trace-cmp hooks to dfsanKostya Serebryany2018-06-011-0/+2
| | | | | | | | | | | | | | | | | | | | | Summary: This allows to build and link the code with e.g. -fsanitize=dataflow -fsanitize-coverage=trace-pc-guard,pc-table,func,trace-cmp w/o providing (all) the definitions of trace-cmp hooks. This is similar to dummy hooks provided by asan/ubsan/msan for the same purpose, except that some of the hooks need to have the __dfsw_ prefix since we need dfsan to replace them.

I propose to change \s into [[:space:]], which is the more portable notation. Test Plan: Run regression tests, and see that they work now. :) Reviewers: pcc, samsonov, emaste Reviewed By: emaste Subscribers: llvm-commits, emaste Differential Revision: http://reviews.llvm.org/D8832 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@234704 91177308-0d34-0410-b5e6-96231b3b80d8
