These are the defects found and fixed so far. Several more have
been observed; I'm working on them.
- Fixed an error in spe_load_uint() that caused incorrect values to be
loaded if the given unsigned value had the low 18 bits as 0,
and that caused inefficient code to be emitted if the given value
had the high 14 bits as 0.
- Fixed a problem in stencil code generation where optional registers
weren't tracked correctly.
- Fixed a problem that the stencil function NEVER was acting as ALWAYS.
- Fixed several problems that could occur if stenciling were enabled but
depth was disabled.
- Fixed a problem with two-sided stencil writemask handling that could
cause a stencil writemask to not be applied.
- Fixed several state permutations that were incorrectly flagged as
not requiring stencil values to be calculated.
Ensures that SPUs are initialized/ready before proceeding.
This fixes a spurious assertion failure when the SPU-side shader function info
hasn't been returned to the PPU before shader codegen.
Lots of restrictions for now (one 2D texture, no mipmaps, etc.) for now
but basic texture demos work.
TEX, TXD, TXP do the same thing for the time being.
Used for SIN, COS, EXP2, LOG2, POW instructions. TEX next.
Fixed some bugs in MIN, MAX, DP3, DP4, DPH instructions.
In rtasm code:
Special-case spe_lqd(), spe_stqd() functions so they take byte offsets but
low-order 4 bits are shifted out. This makes things consistant with SPU
assembly language conventions.
Added spe_get_registers_used() function.
Commit 1680ef8696 changed the texenv program
to get color from a state register instead of a constant-valued vertex
attribute. This broke program concatenation (so glDraw/CopyPixels broke).
Now check if the second program get's color from a constant register and
handle that case appropriately.
If the tnl output attributes matches the swsetup input attributes we still
need to check if the desired vertex color type (float vs. chan) has changed
so that we use the right emit functions.
Fixes a conformance failure found with logicop test at pathlevel 3.
This lets us short-circuit when we're leaving the same cliprects in place,
which becomes quite common with metaops clears, and may be useful for some of
our FBO paths.
