Compiling SPEC CPU 2026 710.omnetpp_r with an AutoFDO profile failed with:
during IPA pass: afdo_offline
internal compiler error: in add, at hash-set.h:64
PHI nodes have no source location, and lookup_count is required to return
null for them. Do not insert that null pointer into the set of matched
profile entriesi.
gcc/ChangeLog:
* auto-profile.cc (function_instance::match): Do not insert a null
entry into counts.
