From ae1ce8ecd3cfd243d6fdc558c0d0f04d073c2290 Mon Sep 17 00:00:00 2001 From: Andres Gomez Date: Fri, 11 Nov 2016 21:03:24 +0200 Subject: [PATCH] glsl: assert on incoherent point mode layout-id-qualifier validation The point mode value in an ast_type_qualifier can only be true if the flag is already set since this layout-id-qualifier can only be or not be present in a shader. Hence, it is useless to check for its value if the flag is already set. Just replaced with an assert. V2: assert instead of checking for coherence and raising a compilation error.
