Bug ID: 33523
Summary: Add a global hotness threshold for emitting remarks
Product: tools
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: opt-viewer
Assignee: unassignedb...@nondot.org
Reporter: ane...@apple.com
CC: ane...@apple.com, llvm-bugs@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
parsing.
