And reappears later in the build.
I put some debug statements in:
if (full_p && insn != NULL_RTX && ep->to_rtx ==
stack_pointer_rtx)
offset -= lra_get_insn_recog_data (insn)->sp_offset;
fprintf( stderr, "dcb: 0 %d\n", XEXP (x, 1));
fprintf( stderr, "dcb: 1 %d\n", CONST_INT_P (XEXP (x, 1)));
fprintf( stderr, "dcb: 2 %d\n", INTVAL (XEXP (x, 1)));
fprintf( stderr, "dcb: 3 %d\n", -offset);
if (CONST_INT_P (XEXP (x, 1)) && INTVAL (XEXP (x, 1)) == -offset)
and got a match on the last debug statement, so I confirm that
it is local variable "offset" that is going wrong.
I'll dig deeper with some more debug statements.
