8 years agoglsl: Replace most assertions with unreachable()

Looking at the generated assembly, it appears that some of changes made
in the generated code prevent some loops from being unrolled.  Removing
the default cases (via unreachable()) allows these loops to unroll again.

Jason Ekstrand [Thu, 25 Aug 2016 08:49:49 +0000 (01:49 -0700)]
anv: Rework pipeline caching

The original pipeline cache the Kristian wrote was based on a now-false
premise that the shaders can be stored in the pipeline cache.  The Vulkan
1.0 spec explicitly states that the pipeline cache object is transiant and
you are allowed to delete it after using it to create a pipeline with no
ill effects.  As nice as Kristian's design was, it doesn't jive with the
expectation provided by the Vulkan spec.

The new pipeline cache uses reference-counted anv_shader_bin objects that
are backed by a large state pool.  The cache itself is just a hash table
mapping keys hashes to anv_shader_bin objects.  This has the added
advantage of removing one more hand-rolled hash table from mesa.

intel/blorp: Add a format parameter to blorp_fast_clear

This allows us to use the actual render format as opposed to the texture
format.  I don't know that the hardware actually cares in the case of fast
clears, but it certainly seems more correct.

the Vulkan driver.

Vulkan, batch will point to the anv_cmd_buffer in which we are building
