[PATCH] D77611: [Sema] Check calls to __attribute__((warn_unused_result)) from StmtExprs

[David Blaikie via Phabricator via cfe-commits]

dblaikie added a comment.

Looks like GCC warns on everything but the last unused expression (the last one being the return statement) - only warning on that last one if it's ultimately unused by the statement expression function call, as it were (& is annotated warn_unused_result). Basically, it models it like a function in a way that Clang perhaps does not?
