Also, we weren't marking the ztile as dirty after ztesting, fixes gears glitches.

Put tile-related globals into spu_global struct.
Rename c/ztile fields to be more consistant.
|
|
Also, remove ALIGN16_ATTRIB from structs that no longer need it.

Forcing cell_array_info to be 16-byte aligned makes it more difficult
to stuff that state in batch commands.

The default value is 0, which is TGSI_PROCESSOR_FRAGMENT...not correct
for a vertex shader!

Unimplemented micro ops get assertions for now.

This was essentially a cut-and-paste bug when the instruction fetcher
was added. Also, the test for TGSI_PROCESSOR_FRAGMENT was moved
outside the loop for exec_declaration.

All of the code is wired in on the SPU side, but it is not called from
the PPU yet. Instruction / declaration fetch still needs to be
implemented in spu_exec.c.

Using the spu_add(), etc intrinsics.
About a 15% speed-up with some tests.

We'll never have more than one of these objects.
Avoiding pointer deref improves performance a bit.

This reduces the emit overhead, which is significant since we're
emiting one vertex at a time.
|
|
It is not being used, and would be dangerous to use given the possibility of constants.

texcyl.c is twice as fast now in non-texture mode
