[Mesa-dev] [PATCH 0/5] anv: Add a NIR cache

This patch series adds a simple NIR shader cache that sits right after
spirv_to_nir and brw_preprocess_nir and before linking.  This should help
alleviate some of the added overhead of link-time optimization since most
of the NIR-level optimization is now cached prior to linking.

I have no numbers to back this series up; just intuition.

Jason Ekstrand (5):
  anv/pipeline: Move wpos and input attachment lowering to lower_nir
  anv/pipeline: Hash shader modules and spec constants separately
  compiler/types: Serialize/deserialize subpass input types correctly
  anv/pipeline_cache: Add support for caching NIR
  anv/pipeline: Cache the pre-lowered NIR
