Hi.
Currently, call to get_working_sets is only called from tree_profiling
(called from 'pass_ipa_tree_profile' and is guarded in gate with
!flag_auto_profile).
I would like to apply the same logic in lto-cgraph.c.
Patch can bootstrap on ppc64le-redhat-linux and survives regression tests.
Ready to be installed?
Martin
