Bug ID: 33523
Summary: Add a global hotness threshold for emitting remarks
Assignee: unassignedbugs at nondot.org
Reporter: anemet at apple.com
CC: anemet at apple.com, llvm-bugs at lists.llvm.org
For large programs, it makes no sense to emit remarks on cold code. If PGO is
available we should not emit remarks on cold code. This should dramatically
improve the performance of opt-viewer since that is bottlenecked on YAML
