re PR target/78614 (ICE error: invalid rtl sharing found in the insn (verify_rtx_sharing) gcc/emit-rtl.c:2743)
PR target/78614
* config/rs6000/rs6000.c (rs6000_frame_related): Call
set_used_flags (pat) before any simplifications. Clear used flag on
PARALLEL copy. Don't guard add_reg_note call. Call
copy_rtx_if_shared on pat before storing it into
REG_FRAME_RELATED_EXPR.
