[Mesa-dev] [PATCH 02/10] glsl: serialize methods for IR instructions
Tapani Pälli
tapani.palli at intel.com
Wed Jan 29 01:24:57 PST 2014
Patch adds a new virtual function for ir_instruction base class which
has to be implemented by each instruction. This data will be used by the
shader binary cache implementation.
