Subject: Workaround for -fprofile-arcs/computed goto failure.
X-Git-Tag: prereleases/egcs-1.1-prerelease~2151
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=11a932c0ffa433aff94e71235ea125df88ed052a;p=thirdparty%2Fgcc.git

Workaround for -fprofile-arcs/computed goto failure.

	* profile.c (branch_prob): If see computed goto, call fatal instead of
	abort.
