Hi,
ipa-fnsplit sometimes ICEs on profile update because
profile_count::adjust_for_ipa_scaling
is called too early.
Bootstrapped/regtested x86_64-linux, will commit it shortly.
PR middle-end/83718
* tree-inline.c (copy_cfg_body): Adjust num&den for scaling
after they are computed.
* g++.dg/torture/pr83718.C: New testcase.
