Subject: cfgrtl: Add missing call to `onlyjump_p'
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=64880a7c49e2f60d1ccabf6798f5b0ea8234edc1;p=gcc.git

cfgrtl: Add missing call to `onlyjump_p'

If any unconditional jumps within a block have side effects then the
block cannot be considered empty.

	gcc/
	* cfgrtl.c (rtl_block_empty_p): Return false if `!onlyjump_p'
	too.
