Richard Smith	7c7e531f97	PR31978: Don't crash if CodeGen sees a top-level BindingDecl. ... llvm-svn: 345362	2018-10-26 03:21:20 +00:00
Zhihao Yuan	c81f4538ec	Allow conditions to be decomposed with structured bindings ... Summary: This feature was discussed but not yet proposed. It allows a structured binding to appear as a //condition// if (auto [ok, val] = f(...)) So the user can save an extra //condition// if the statement can test the value to-be-decomposed instead. Formally, it makes the value of the underlying object of the structured binding declaration also the value of a //condition// that is an initialized declaration. Considering its logicality which is entirely evident from its trivial implementation, I think it might be acceptable to land it as an extension for now before I write the paper.

Richard Smith	bdb84f374c	P0217R3: Parsing support and framework for AST representation of C++1z ... decomposition declarations. There are a couple of things in the wording that seem strange here: decomposition declarations are permitted at namespace scope (which we partially support here) and they are permitted as the declaration in a template (which we reject). llvm-svn: 276492	2016-07-22 23:36:59 +00:00
