Subject: cfgrtl: Add missing call to `onlyjump_p'
X-Git-Tag: basepoints/gcc-12~2486
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=64880a7c49e2f60d1ccabf6798f5b0ea8234edc1;p=thirdparty%2Fgcc.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.
