Subject: libstdc++, coroutine: Add missing constexpr markers.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f1b6e46c417224887c2f21baa6d4c538a25fe9fb;p=gcc.git

libstdc++, coroutine: Add missing constexpr markers.

The methods of the trivial awaitables are intended to
be constexpr.

libstdc++-v3/ChangeLog:

	* include/std/coroutine: Mark the methods of the
	trivial awaitables as constexpr.
