X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2a62e439fb7289b71e2e9eb500091b561a8fe1f7;p=gcc.git

except.c: Use rtx_sequence

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

	* except.c (can_throw_external): Strengthen local "seq" from rtx
	to rtx_sequence *.  Use methods of rtx_sequence.
	(insn_nothrow_p): Likewise.
