As mentioned in the PR, we miss one initialization of ::punned
in vn_reference_lookup_call.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
Thanks,
Martin
gcc/ChangeLog:
PR tree-optimization/96597
* tree-ssa-sccvn.c (vn_reference_lookup_call): Add missing
initialization of ::punned.
(vn_reference_insert): Use consistently false instead of 0.
(vn_reference_insert_pieces): Likewise.
