Is there reason to prevent the inlining once instrumentation is done?
No ;)
I think you can just block it for early inliner.
Sure. Do you have a handy predicate function that tells if einliner
is done?
Thanks,

Hello.
There's updated version of that patch that blocks inlining only during
einline IPA pass.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
Thanks,
Martin

Subject: [PATCH] inline: do not einline when no_profile_instrument_function is
different
PR gcov-profile/80223
gcc/ChangeLog:
* ipa-inline.c (can_inline_edge_p): Similarly to sanitizer
options, do not inline when no_profile_instrument_function
attributes are different in early inliner. It's fine to inline
it after PGO instrumentation.
OK
