[Mesa-dev] [PATCH 4/5] anv/pipeline: Store the (set, binding, index) tripple in the bind map

Jason Ekstrand jason at jlekstrand.net
Mon Jun 6 18:26:31 UTC 2016


This way the the bind map (which we're caching) is mostly independent of
the pipeline layout.  The only coupling remaining is that we pull the array
size of a binding out of the layout.  However, that size is also specified
in the shader and should always match so it's not really coupled.  This
rendering issues in Dota 2.
