Subject: (length attribute): Branches may be expanded to two instructions by the assembler.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c329c9bbcdb6975c359a26df577ab6d65a6b9263;p=gcc.git

(length attribute): Branches may be expanded to two instructions by the assembler.

(length attribute): Branches may be expanded to two
	instructions by the assembler.
	(DFmode bcnd pattern): Don't try to fill the delay slot.
	(CCmode bbx patterns): Reverse the 1/0, not the condition.
(BLKmode load/store patterns): New.
	(call_block_move, call_movstrsi_loop): Allow any mode for the preload.
