Commit Message

David Malcolm June 6, 2018, 2:21 p.m. UTC 
Eliminate an "as_a <rtx_insn *>()" cast.

Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.

I'm treating this as pre-approved, under the pre-approval on
rtx -> rtx_insn * cleanups here:
  https://gcc.gnu.org/ml/gcc-patches/2014-08/msg01310.html

Committed to trunk as r261233.

gcc/ChangeLog:
	* config/i386/i386-protos.h (ix86_expand_call): Strengthen return
	type from "rtx" to "rtx_insn *".
	* config/i386/i386.c (ix86_expand_split_stack_prologue): Likewise
	for local "call_insn", removing cast.
	(ix86_expand_call): Likewise, introducing a "call_insn" local.
