Hi,
what's the reason for dwarf2out_frame_debug_expr not caring about
the RTX_FRAME_RELATED_P flag of an insn if it is a simple set. It only draws
the frame related flags of SETs contained in a PARALLEL beginning with the
second into account. A comment mentions backward compatibility as the reason.
I wonder to what it is tried to be compatible here.
Can anybody tell me how a single move of an register to the stack can be marked
as frame unrelated?
Bye,
-Andreas-

Hi,
the check for RTX_FRAME_RELATED_P is done by the caller of
dwarf2out_frame_debug_expr. No idea why I've overlooked this.
So please ignore my last mail.
Bye,
