From 4e62a2c4b2c809ea020423e7e328ba96e379d64d Mon Sep 17 00:00:00 2001 From: Bernhard Schommer Date: Wed, 23 Mar 2016 14:22:33 +0100 Subject: Added the _Noreturn keyword. CompCert now recognizes the C11 _Noreturn function specifier and emits a simple warning for functions declared _Noreturn containing a return statement. Also the stdnoreturn header and additionally the stdalign header are added.
