Subject: Handle [[likely]] on compound-statement.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ffe6a780adb8e958e77eb335d9cc540ef6668e67;p=thirdparty%2Fgcc.git

Handle [[likely]] on compound-statement.

I overlooked this case when adding [[likely]] handling to
cp_parser_statement.

	* parser.c (cp_parser_statement): Handle [[likely]] on
	compound-statement.
