Dean Michael Berris	0f84a7d355	[XRay][tools] Support tail-call exits before we write them in the runtime ... Summary: This change adds support for explicit tail-exit records to be written by the XRay runtime. This lets us differentiate the tail exit records/events in the log, and allows us to treat those exit events especially in the future. For now we allow printing those out in YAML (and reading them in).

Dean Michael Berris	4f83c4d1a6	[XRAY] [x86_64] Adding a Flight Data filetype reader to the llvm-xray Trace implementation. ... Summary: The file type packs function trace data onto disk from potentially multiple threads that are aggregated and flushed during the course of an instrumented program's runtime. It is named FDR mode or Flight Data recorder as an analogy to plane blackboxes, which instrument a running system without access to IO. The writer code is defined in compiler-rt in xray_fdr_logging.h/cc Reviewers: rSerge, kcc, dberris Reviewed By: dberris Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D29697 llvm-svn: 295397	2017-02-17 01:47:16 +00:00
