Summary: This change updates the version number for FDR logs to 5, and update the trace processing to support changes in the custom event records. In the runtime, since we're already writing down the record preamble to handle CPU migrations and TSC wraparound, we can use the same TSC delta encoding in the custom event and typed event records that we use in function event records. We do the same change to typed events (which were unsupported before this change in the trace processing) which now show up in the trace. Future changes should increase our testing coverage to make custom and typed events as first class entities in the FDR mode log processing tools. This change is also a good example of how we end up supporting new record types in the FDR mode implementation. This shows the places where new record types are added and supported. Depends on D54139. Reviewers: mboerger Subscribers: hiraditya, arphaman, jfb, llvm-commits Differential Revision: https://reviews.llvm.org/D54140 llvm-svn: 346293
