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
