From 2f19accc5ecdff29c9300f0eceb420c0b1538b24 Mon Sep 17 00:00:00 2001 From: Timothy Arceri Date: Sun, 20 Nov 2016 12:47:00 +1100 Subject: [PATCH] mesa/glsl: add cache_fallback flag to gl_shader_program_data MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This will allow us to skip certain things when falling back to a full recompile on a cache miss such as avoiding reinitialising uniforms. In this change we use it to avoid reading the program metadata from the cache and skipping linking during a fallback.
