Group inputs/outputs, in addition to fanin/fanout, as they must also
exist in sequential scalar registers. This lets us simplify RA by
working in terms of neighbor groups.
NOTE: has the slight problem that it can't optimize out mov's for things
like:
MOV OUT[n], IN[m]
To avoid this, instead of trying to figure out what mov's we can
eliminate, we first remove all mov's prior to grouping, and then
re-insert mov's as needed while grouping inputs/outputs/fanins.
Eventually we'd prefer the frontend to not insert extra mov's in the
first place (so we don't have to bother removing them). This is the
plan for an eventual NIR based frontend, so separate out the instr
grouping (which will still be needed for NIR frontend) from the mov
elimination (which won't).

For temp arrays, a 32bit mask won't be sufficient.. but otoh we don't
need to support an arbitrary mask. So for this case use a simple size
field rather than a bitmask.

We probably could be more clever elsewhere and mask out components that
are not used. But either way, legalize should realize that there is
also a write-after-write hazard with texture sample instructions.

NOTE IN[] and OUT[] don't need (have?) ArrayID's.. and TEMP[] can
optionally have them. So we implicitly assume that ArrayID==0 always
exists for each file. This is why array_max[file] is never less than
zero.
You can tell from indirect_files(_read/written) if the legacy array-
id zero was actually used.

At least temporarily, I need to fallback to old compiler still for
relative dest (for freedreno), but I can do relative src temp. Only
a temporary situation, but seems easy/reasonable for tgsi-scan to
track this.

We were invalidating si_screen:tm by calling
r600_destroy_common_screen() which frees the si_screen object. This
caused the driver to crash in LLVMDisposeTargetMachine() since we
were passing it an invalid pointer.

It doesn't work on Windows because of STDCALL calling convention -- it's
the callee responsibility to pop the arguments, and the number of
arguments vary with the prototype --, so the stack pointer ends up getting
corrupted.
This is just a non-invasive stop-gap fix. A proper fix would be more
elaborate, and require either:
- a variation of __glapi_noop_table which sets GL_INVALID_OPERATION
error
- stop using APIENTRY on all internal _mesa_* functions.
Tested with piglit gl-1.0-beginend-coverage (it now fails instead of
crashing).

The only problem is with index buffers, which don't use TC.

It's causing problems, because we mix uncached CP DMA with cached WRITE_DATA

The solution for SI is to use uncached access here, because CP DMA doesn't
support cached access.

That's either framebuffer caches or caches for shader resources.
The motivation is that framebuffer caches need to be flushed very rarely

Ordered compares are what you have in C. Unordered compares are the result
of negating ordered compares (they return true if either argument is NaN).
That special NaN behavior is completely useless here, and unordered
compares produce horrible code with all stable LLVM versions.

Rather than building a new one every compile. This should reduce some
of the overhead of compiling shaders.
One consequence of this change is that we lose the MachineInstrs dumps
when dumping the shaders via R600_DEBUG. The LLVM IR and assembly is
still dumped, and if you still want to see the MachineInstr dump, you
can run the dumped LLVM IR through llc.
