Sync'd with Amir offline. We agreed that we should drop the new option `--instrument-funcs-file`, start using option `--instrument-hot-only` and pass the list of functions intended to be instrumented in a new `fdata` format to BOLT. With a new format, the fdata reader can freely match against restored symbol names for local functions. This PR will be closed.
