*	Update the file headers across all of the LLVM projects in the monorepo	Chandler Carruth	2019-01-19	1	-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. llvm-svn: 351636
*	[XRay][compiler-rt] Refactor recursion guard for Basic and FDR Mode	Dean Michael Berris	2018-06-06	1	-0/+57
	Summary: This change extracts the recursion guard implementation from FDR Mode and updates it to do the following: - Do the atomic operation correctly to be signal-handler safe. - Make it usable in both FDR and Basic Modes. Before this change, the recursion guard relied on an unsynchronised read and write on a volatile thread-local. A signal handler could then run in between the read and the write, and then be able to run instrumented code as part of the signal handling. Using an atomic exchange instead fixes that by doing a proper mutual exclusion even in the presence of signal handling.
