--- Comment #9 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <[email protected]>: https://gcc.gnu.org/g:d45381550ec25de9c5eb7168bad85586109b4991 commit r17-4774-gd45381550ec25de9c5eb7168bad85586109b4991 Author: Richard Biener <[email protected]> Date: Tue Sep 29 13:15:07 2026 +0200 tree-optimization/60075 - fix address-space handling in PRE The following fixes a thinko in COMPONENT_REF handling in VN/PRE where we falsely assumed the type of the FIELD_DECL specifies the type of the COMPONENT_REF in full, disregarding address-space qualification. PR tree-optimization/60075 * tree-ssa-sccvn.cc (copy_reference_ops_from_ref): Do not use the type of the FIELD_DECL for COMPONENT_REF ops. * tree-ssa-pre.cc (create_component_ref_by_pieces_1): Likewise. * gcc.target/avr/pr60075.c: New testcase.
