--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Already reproduces with plain -O1.
Value numbering stmt = _1 = BIT_FIELD_REF <Local_R1, 8, 56>;
Successfully combined 2 partial definitions
Setting value number of _1 to 0 (changed)
Replaced BIT_FIELD_REF <Local_R1, 8, 56> with 0 in all uses of _1 =
BIT_FIELD_REF <Local_R1, 8, 56>;
Jakub just pushed a fix here (PR97764), which fixes this issue.
