From e84cb56f483d5470d0ac350c146c8387622362b5 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 8 May 2017 16:30:58 -0700 Subject: [PATCH] i965: Make a helper function for depth/stencil related state. Gen4-5 basically glue DEPTH_STENCIL_STATE, COLOR_CALC_STATE, and BLEND_STATE together into a single COLOR_CALC_STATE structure. By making a helper function, we'll be able to reuse it when filling out Gen4-5 COLOR_CALC_STATE without replicating any actual logic. We use generation-defined typedef to handle the polymorphism.
