From: Timothy Arceri Date: Sun, 5 Jun 2016 03:17:51 +0000 (+1000) Subject: mesa/glsl: stop using GL shader type internally X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=31dee99e052902bc08ddbb1009748dc982ac3211;p=mesa.git mesa/glsl: stop using GL shader type internally Instead use the internal gl_shader_stage enum everywhere. This makes things more consistent and gets rid of unnecessary conversions. Ideally it would be nice to remove the Type field from gl_shader altogether but currently it is used to differentiate between gl_shader and gl_shader_program in the ShaderObjects hash table.
