We'll use this for debug/sanity checking.

This branch introduces new FRAG_ATTRIB_FACE and FRAG_ATTRIB_PNTC fragment
program inputs for GLSL gl_FrontFacing and gl_PointCoord. Before, these
attributes were packed with the FOG attribute. That made things
complicated elsewhere.
|
|
Fixes cube mapping since the scalar changes.
|
|
This is preparation for merging of brw_wm_glsl.c and
brw_wm_emit.c, and glsl.c doesn't swizzle channel results around.

Bug #20821
|
|
Previously, the FOGC attribute contained the fragment fog coord, front/back-
face flag and the gl_PointCoord.xy values. Now each of those things are
separate fragment program attributes. This simplifies quite a few things in
Mesa and gallium.
Need to test i965 driver and fix up point coord handling in the gallium/draw
module...

For the TXP instruction we check if the texcoord is really a 4-component
atttibute which requires the divide by W step. This check involved the
projtex_mask field. However, the projtex_mask field was being miscalculated
because of some confusion between vertex program outputs and fragment
program inputs.
1. Rework the size_masks calculation so we correctly set bits corresponding
to fragment program input attributes.
2. Rename projtex_mask to proj_attrib_mask since we're interested in more
than just texcoords (generic varying vars too).
3. Simply the indexing of the size_masks and proj_attrib_mask fields.
4. The tracker::active[] array was mis-dimensioned. Use MAX_PROGRAM_TEMPS
instead of a magic number.
5. Update comments, add new assertions.
With these changes the Lightsmark demo/benchmark renders correctly, until
we eventually hit a GPU lockup...

...rather than with linear interpolation. Modern hardware should use
perspective-corrected interpolation for colors (as for texcoords).
glHint(GL_PERSPECTIVE_CORRECTION_HINT, mode) can be used to get
linear interpolation if mode = GL_FASTEST.

There's really no need for two negation fields. This came from the
GL_NV_fragment_program extension. The new, unified Negate bitfield applies
after the absolute value step.
|
|
This also cuts instructions by just using the existing bit in the payload
rather than computing it from the determinant in the SF unit and passing it
as a varying down to the WM. Something still goes wrong with getting the
backface color right, but a simpler shader appears to get the right result.
|
|
Previously, we would sample (f,glFrontFacing,undef,undef) instead of the
(f,0,0,1) that fragment.fogcoord is supposed to return. Due to
glFrontFacing's presence in FOGC.y, we'll still give bad results there when
glFrontFacing is used.

Plus fix up a debug printf.

Remove FRAG_RESULT_COLH (NV half-precision) output since we never used it.
Next, we might merge the COLOR and DATA outputs (COLOR0, COLOR1, etc).
|
|
Be a little more specific about what these are.

The i965 driver needs an extra instruction field for color output information.
It was using the Sampler field for this. Use the Aux field instead. This
will probaby be revisited at some point...

GLSL shadow() sampler calls are properly propogated down to the driver now.
The glean glsl1 shadow() tests work (except for the alpha channel).

Previously, the prog_instruction::Data field was used to map original Mesa
instructions to brw instructions in order to resolve subroutine calls. This
was a rather tangled mess. Plus it's an obstacle to implementing dynamic
allocation/growing of the instruction buffer (it's still a fixed size).
Mesa's GLSL compiler emits a label for each subroutine and CAL instruction.
Now we use those labels to patch the subroutine calls after code generation
has been done. We just keep a list of all CAL instructions that needs patching
and a list of all subroutine labels. It's a simple matter to resolve them.
This also consolidates some redundant post-emit code between brw_vs_emit.c and
brw_wm_glsl.c and removes some loops that cleared the prog_instruction::Data
fields at the end.
Plus, a bunch of new comments.

Just to reinforce the understanding that an extended swizzle with 0 and 1
terms is possible there.
|
|
If the texture swizzle is not XYZW (no-op) add an extra MOV instruction
after the TEX instruction to rearrange the components.
|
|
|

Just call _mesa_append_fog_code() if the fragment program's FogOption is
not GL_NONE.
This allows us to remove some unnecessary i965 fog code.
Note, the arbfplight.c demo can be used to test this (see DO_FRAGMENT_FOG).
|
|
If gl_FragData[0] is written but not gl_FragCOlor, use the former.

This is fallout from the ffvertex_prog.c work. It doesn't call
ProgramStringNotify, so we don't set param_state, so we wouldn't track when
VP parameters changed, and constants wouldn't get uploaded. Instead, remove
param_state entirely and just use the real value that we want to be tracking.
Fixes rendering in openarena since BRW_NEW_BATCH got disentangled from
BRW_NEW_INDICES.

inst->TexSrcUnit is used as an index into program->SamplerUnits[] since
the commit ade508312c701ce89d3c2cd717994dbbabb4f207, and program->SamplerUnits
is a sampler-to-texture-unit mapping.

This patch is a variant of a submission by Michal Wajdeczko to fix
oglconform fpalu failures.

Also, use wrapped ffs() instead of native.

1. Follow EXT_texture_rectangle with YCbCr texture
2. swap UV component for MESA_FORMAT_YCBCR

projtex_mask is only an 8bit field, and wm.input_size_masks includes
other attributes' information, therefore right shift is needed.

StateFlags has been updated in _mesa_add_state_reference

Mostly:
- update #includes
- update STATE_* token code
