Summary: Feature request: Temporal PGO support for GCC
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: gcov-profile
Assignee: unassigned at gcc dot gnu.org
Reporter: zamazan4ik at tut dot by
Target Milestone: ---
Clang has support for a specific PGO kind - Temporal PGO:
https://clang.llvm.org/docs/UsersManual.html#cmdoption-ftemporal-profile More
details about this feature is here (RFC):
https://discourse.llvm.org/t/rfc-temporal-profiling-extension-for-irpgo/68068
This PGO kind optimizes application startup times that is also useful for
applications. It would be nice to have support to something similar with GCC
too for having feature parity with Clang in this area.
