Subject: Make a temporary sequence for a jump emitted only to examine its length.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ed2b2162d0b3953789156bae4e1ece1a7991e305;p=gcc.git

Make a temporary sequence for a jump emitted only to examine its length.

	* bb-reorder.c (get_uncond_jump_length): Avoid using delete_insn,
	emit into a sequence instead.
