Subject: coroutines: co_returns are statements, not expressions.
X-Git-Tag: upstream/12.2.0~15946
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=608832716e27ca356ee38d14ae30b3ab525884ea;p=platform%2Fupstream%2Fgcc.git

coroutines: co_returns are statements, not expressions.

This corrects an error in the CO_RETURN_EXPR tree
class.

gcc/cp/ChangeLog:

	* cp-tree.def (CO_RETURN_EXPR): Correct the class
	to use tcc_statement.
