Subject: (output_cbranch): When checking for a jump to the given insn's delay slot...
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=46f9b8286325de315c27246a30e43001ebf85042;p=gcc.git

(output_cbranch): When checking for a jump to the given insn's delay slot...

(output_cbranch): When checking for a jump to the given insn's delay
slot, handle the case where JUMP_LABEL for the given insn does not
point to the first label in a series of labels.
(output_bb, output_dbra, output_movb): Likewise.
