mesa/compiler: rework tear down of builtin/types

The issue we're running into when running CTS is that glsl types are
deleted while builtins depending on them are not.

This happens because on one hand we have glsl types ref counted, but
builtins are not. Instead builtins are destroyed when unloading libGL
or explicitly calling glReleaseShaderCompiler().

This change removes almost entirely any dealing with glsl types
ref/unref by letting the builtins deal with it instead. In turn we
introduce a builtin ref count mechanism. Each GL context takes a
reference on the builtins when compiling a shader for the first time.
It releases the reference when the context is destroyed. It can also
explicitly release those when glReleaseShaderCompiler() is called.

Finally we also take a reference on the glsl types when loading libGL
to avoid recreating glsl types too often.

4 years agopan/midgard: Compute liveness per-block
Alyssa Rosenzweig [Thu, 15 Aug 2019 21:53:56 +0000 (14:53 -0700)]
pan/midgard: Compute liveness per-block

Rather than using a regalloc based on live internals, computed hastily
with repeated invocations of a forward-analysis pass, we switch to
compute liveness information on a per-block basis.

Within a given basic block, we compute liveness backwards with a
linear-time algorithm; for common shaders, this may help RA terminate
quicker.

Across blocks, we use a work list (really a work set) and check if we're
making progress. This isn't terribly efficient, but it gets the job
done. Point is, we get the live_in/live_out for each block.

From there, it's simple to rerun the linear-time update algorithm to
compute the interference graph.

The benefit of this technique is the ability to ignore "gaps" in
liveness across intermediate blocks that are never executed. On simple
shaders like the loops in glmark, this results in a minor reduction in
register pressure. The motivation was a complex shader in Krita that
failed register allocation due to an unfortunate interaction between
texture pipeline registers and control flow. This shader now compiles
successfully.
