From f196eb2d39d334b3ac8fbc5c0513dcb25e725155 Mon Sep 17 00:00:00 2001 From: Carl Worth Date: Wed, 25 Jun 2014 13:07:44 -0700 Subject: glsl: Add an internal-error catch-all rule This is to avoid the default, silent flex rule which simply prints the character to stdout. For the following Khronos GLES3 conformance tests: invalid_char_in_name_vertex invalid_char_in_name_fragment With this commit, these tests now report Pass where they previously reported Fail, but Mesa isn't behaving correctly yet. It's now reporting the internal error where what is really desired is a syntax error.
