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.
