[Mesa-dev] [PATCH v2 03/64] mesa: implement ARB_bindless_texture
Samuel Pitoiset
samuel.pitoiset at gmail.com
Tue May 30 20:35:34 UTC 2017
v2: - s/GLboolean/bool for HandleAllocated
- fix _mesa_has_ARB_shader_image_load_store() checks
- use u_vector for texture/image handles
- fix use of 64-bit handles on 32-bit systems
- some cleanups
