Sorry about this.

The issue is here:

  3042insn = as_a rtx_insn * (
  3043 gen_extend_insn (op0, t, promoted_nominal_mode,
  3044  data-passed_mode, unsignedp));

which I mistakenly introduced in r214698.

The result of the gen_extend_insn is a SET, not an insn:

(set (reg/v:DI 151 [ ptrres ])
(zero_extend:DI (mem/f/c:SI (reg/f:SI 77 virtual-incoming-args) [8 ptrres+0
S4 A64])))

hence the as_a rtx_insn * fails.

Am attaching a patch which appears to fix it.
