From 0610a624a1286cec1b9a0a19be63f46aae518377 Mon Sep 17 00:00:00 2001 From: Jordan Justen Date: Fri, 13 Oct 2017 13:07:50 -0700 Subject: [PATCH] i965/link: Serialize program to nir after linking for shader cache If the shader cache is enabled, after linking the program, we serialize the program to nir. This will be saved out by the glsl shader cache support. Later, if the same program is found in the cache, we can use the nir for a fallback in the unlikely case that the gen binary program is not found in the cache.
