Subject: function.c: Use rtx_sequence
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e0944870710b48ad98e10e17ac0ae23995947573;p=gcc.git

function.c: Use rtx_sequence

gcc/
2014-08-27  David Malcolm  <dmalcolm@redhat.com>

	* function.c (contains): Introduce local "seq" for PATTERN (insn),
	with a checked cast, in the region for where we know it's a
	SEQUENCE.  Use methods of rtx_sequence.
