From 5d7275c350f1e05f7c9a06316e1826bf42bb769b Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Wed, 18 Jun 2014 15:43:32 -0700 Subject: [PATCH] glsl_to_tgsi: Assert that the _mesa_sysval_to_semantic mapping is correct MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Future patches will rearrange the values in gl_system_value, and I want to catch errors. Designated initializers would make all of this unnecessary. v2: Don't use STATIC_ASSERT. Not only does it not work, but GCC doesn't tell you that it's not going to work. Thanks for nothing!
