dwarf2out.c (dwarf2out_frame_debug): Assume that in a PARALLEL prologue insn, only the first elt is significant.
* dwarf2out.c (dwarf2out_frame_debug): Assume that in a PARALLEL
prologue insn, only the first elt is significant.
(output_call_frame_info): For exception handling, always use 4-byte
fields as specified by the dwarf2 spec.
Don't skip trivial FDEs.
