From: Timothy Arceri Date: Fri, 4 Nov 2016 09:02:21 +0000 (+1100) Subject: st/mesa/glsl/i965: move ImageUnits and ImageAccess fields to gl_program X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a1da57c19c27505b9eab4792355f2f1b5c774a0a;p=mesa.git st/mesa/glsl/i965: move ImageUnits and ImageAccess fields to gl_program Having it here rather than in gl_linked_shader allows us to simplify the code. Also it is error prone to depend on the gl_linked_shader for programs in current use because a failed linking attempt will free infomation about the current program. In i965 we could be trying to recompile a shader variant but may have lost some required fields. We drop the memset on ImageUnits because gl_program is already created using rzalloc().
