- The previous solution was hacky and didn't do subchannel autobinding.
- The beheaviour should match what libdrm_nouveau does closely.
- The solution remains statically sized, but when debugging is on it will check
for abuse.

- unreference state objects so that buffer objects are unreferenced and
eventually destroyed
- free channel at screen's destruction
Based on Krzysztof Smiechowicz's patch.

CMP and SCS can produce incorrect results if the source and
destination are the same.
This patch should fix the issues.
CMP is fixed by predicating both moves.
SCS by changing the order if the source component is X.

Rename Semantic.SemanticName to Semantic.Name. Similar for
SemanticIndex, and the members of the tgsi_version struct.

It would be nice if these drivers built under the linux-debug header
so that these types of interface changes can be minimally propogated
into those drivers by people without the hardware. They don't have to
generate a working driver -- though a command-dumping winsys would be
an excellent for regression checking.
|
|
Likewise, the extended negate functionality hasn't been
used since mesa switched to using tgsi_ureg to build programs,
and has been translating the SWZ opcode internally to a single MAD.
|
|
These haven't been used by the mesa state tracker since the
conversion to tgsi_ureg, and it seems that none of the
other state trackers are using it either.
This helps simplify one of the biggest suprises when starting off with
TGSI shaders.

Provide a dummy implementation in the GL state tracker (move 0.5 to
the destination regs).
At some point, a motivated person could add a better
implementation of noise. Currently not even the nvidia
binary drivers do anything more than this. In any case, the
place to do this is in the GL state tracker, not the poor
driver.

Remove the need to have a pointer in this struct by just including
the immediate data inline. Having a pointer in the struct introduces
complications like needing to alloc/free the data pointed to, uncertainty
about who owns the data, etc. There doesn't seem to be a need for it,
and it is unlikely to make much difference plus or minus to performance.
Added some asserts as we now will trip up on immediates with more
than four elements. There were actually already quite a few such asserts,
but the >4 case could be used in the future to specify indexable immediate
ranges, such as lookup tables.

The core reference counting code is centralized in p_refcnt.h.
This has some consequences related to struct pipe_buffer:
* The screen member of struct pipe_buffer must be initialized, or
pipe_buffer_reference() will crash trying to destroy a buffer with reference
count 0. u_simple_screen takes care of this, but I may have missed some of
the drivers not using it.
* Except for rare exceptions deep in winsys code, buffers must always be
allocated via pipe_buffer_create() or via screen->*buffer_create() rather
than via winsys->*buffer_create().

Fixes arbfplight "sticking".

Should hopefully be OK now (on the fragprog size) for MRT. The hack from
a commit 01cb2cd93efe7ad94d7fd36aa5a776c2e3ab4c7d is no longer needed.

Temporary, the fp reg handling will get reworked at some point in the near
future. But before that, there's a few bugs to find.

For the moment, we do what NVIDIA does and return 0 unconditionally. This
isn't correct, but it's an implementation at least.
