* 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. llvm-svn: 351636
* [XRay] Add clang builtin for xray typed events.Keith Wyss2018-04-171-0/+1
| | | | | | | | | | | | | | | | | | | Summary: A clang builtin for xray typed events. Differs from __xray_customevent(...) by the presence of a type tag that is vended by compiler-rt in typical usage. This allows xray handlers to expand logged events with their type description and plugins to process traced events based on type. This change depends on D45633 for the intrinsic definition.

* [XRay][clang] Add flag to choose instrumentation bundlesDean Michael Berris2018-04-131-0/+29
Summary: This change addresses http://llvm.org/PR36926 by allowing users to pick which instrumentation bundles to use, when instrumenting with XRay. In particular, the flag `-fxray-instrumentation-bundle=` has four valid values: - `all`: the default, emits all instrumentation kinds - `none`: equivalent to -fnoxray-instrument - `function`: emits the entry/exit instrumentation - `custom`: emits the custom event instrumentation These can be combined either as comma-separated values, or as repeated flag values.
