Ivan Gyurdiev 33293df143 wined3d: More flow control instructions.
- Implement call, callnz, label, and ret
- Implement support for NOT modifier
2006-07-11 17:14:24 +02:00
Ivan Gyurdiev 6ede56495a wined3d: More flow control instructions
- Implement if, else, endif, rep, endrep, break
- Implement ifc, breakc, using undocumented comparison bits in the instruction token
- Fix bug in main loop processing of codes with no dst token
- Fix bug in GLSL output modifier processing of codes with no dst token
- Fix bug in loop implementation (src1 contains the integer data, src0 is aL)
- Add versioning for all the instructions above, and remove
  GLSL_REQUIRED thing, which is useless and should be removed from all
  opcodes in general.

Ivan Gyurdiev e9de563e41 wined3d: Place immediate constants in the same array as global constants.
- move DEF, DEFI, DEFB handling into the register counting pass
- keep track of defined constants as a linked list (because there's a
  few of them)
- apply immediate constants after global constants in the constant
  loading function
- both types of constants now get loaded with array notation in the
  shader (into the same array)

Ivan Gyurdiev 5638fac685 wined3d: Trace ABS/ABSNEG modifiers. 2006-07-07 17:40:03 +02:00
Ivan Gyurdiev 5b3c500efe wined3d: Reverse semantics maps for shaders. 2006-07-07 17:39:26 +02:00
Ivan Gyurdiev 276609e1e5 wined3d: Move register count pass to SetFunction.
Move semantics pointers out of the reg_maps, make them persistent data
in the shader (again, for future software shaders).

Ivan Gyurdiev 771623692e wined3d: Rework shader mode selection.
- currently half the shader selection code (GLSL vs ARB) is in
fillGLcaps. The parts that check for software shaders are in
GetDeviceCaps. That placement, will work, but is definitely not optimal.
FillGLcaps should detect support - it should not make decision as to
what's used, because that's not what the purpose of the function is.
GetDeviceCaps should report support as it has already been selected.
Instead, select shader mode in its own function, called in the
appropriate places.

- unifying pixel and vertex shaders into a single selection is a
mistake. A software vertex shader can be coupled with a hardware arb or
glsl pixel shader, or no shader at all. Split them back into two and add
a SHADER_NONE variant.

- drawprim is doing support checks for ARB_PROGRAM, and making shader
decisions based on that - that's wrong, support has already been
checked, and decided upon, and shaders can be implemented via software,
ARB_PROGRAm or GLSL, so that support check isn't valid.

- Store the shader selected mode into the shader itself. Different types
of shaders can be combined, so this is an improvement. In fact, storing
the mode into the settings globally is a mistake as well - it should be
done per device, since different cards have different capabilities.

Ivan Gyurdiev 0111e15e1f wined3d: Fix faulty DCL trace. 2006-07-03 12:04:23 +02:00
Ivan Gyurdiev fd896d8652 wined3d: Use shader_get_regtype() in register counting pass. 2006-07-03 12:03:58 +02:00
Jason Green 4fbe97e5e7 wined3d: Fix a few GLSL shader instruction translations.
This fixes the translations for a few instructions in GLSL and allows
Cubemap sampling in pixel shaders < 2.0.  It makes some of the
lighting on textures in Half Life 2 look better, including some of the
water effects.  It's not perfect yet, but much closer now.
2006-06-29 14:41:01 +02:00
Jason Green baf38b3007 wined3d: Implement more GLSL instructions and a little cleanup.
- Implement D3DSIO_DP2ADD, D3DSIO_TEXKILL, D3DSIO_TEXM3X3PAD
- Partially implement D3DSIO_TEXBEM, D3DSIO_TEXM3X3VSPEC (as much as
  they are implemented in ARB_fragment_program at least).
- Stop copying the SHADER_PARSE_STATE struct in each ARB shader
  routine - use a pointer instead.

Jason Green 0b09ecb291 wined3d: Move D3DSIO_DEF instruction for ARB shaders into arb_program_shader.c. 2006-06-20 11:28:15 +02:00
Jason Green fd83de7129 wined3d: Fix lookup for LOOP register. 2006-06-19 11:11:24 +02:00
Jason Green 34d271bab6 wined3d: Add preliminary support for constant boolean and integer registers in GLSL.
- Separate the declaration phase of the shader string generator into
  the arb and glsl specific files.
- Add declarations and recognition for application-sent constant
  integers and booleans (locally defined ones will follow).
- Standardize capitilization of pixel/vertex specific variable names.
2006-06-19 10:50:14 +02:00
Jason Green cc06ed3d53 wined3d: Implement more GLSL instructions.
- Implemented: D3DSIO_SGN, LOOP, ENDLOOP, LOGP, LIT, DST, SINCOS
- Process instruction-based modifiers (function existed, it just
  wasn't being called)
- Add loop checking to register maps.
- Renamed "sng" to "sgn" for D3DSIO_SGN - it's not handled anywhere
  except for GLSL, so won't matter.

Ivan Gyurdiev 8c6ee8df0d wined3d: Mark instructions without a destination token.
There are a total of 17 instructions without a destination token. Of
those 9 have num_params != 0, which means that we will not process any
of them correctly, because we assume the first token (if present) is a
destination token.

Those are basically all the flow control instructions, which we plan to
support very soon. They have source tokens, and no destination. Add a
flag that marks them up to the ins table. Use this flag in the trace
pass, and generation pass.

Ivan Gyurdiev 14a52e5c09 wined3d: Keep pshader and vshader constants in GLSL separate.
GLSL uniforms have as scope the entire program.
To prevent conflicts, name pshader and vshader constants differently.
Based on a patch by Jason Green.
2006-06-13 11:40:22 +02:00
Ivan Gyurdiev 0d08316523 wined3d: Improve Sampler support on 2.0 and 3.0 shaders.
- track sampler declarations and store the sampler usage in reg_maps structure
- store a fake sampler usage for 1.X shaders (defined as 2D sampler)
- re-sync glsl TEX implementation with the ARB one (no idea why they diverged..)
- use sampler type in new TEX implementation to support 2D, 3D, and Cube sampling
- change drawprim to bind pixel shader samplers

Additional improvements:
- rename texture limit to texcoord to prevent confusion
- add sampler limit, and use that for samplers - *not* the same as texcoord above

Ivan Gyurdiev a1f4dfe4e3 wined3d: Add support for shader model 3.0 I/O registers.
SM 3.0 can pack multiple "semantics" into 12 generic input/output registers.

To support that, define temporaries called IN and OUT, and use those as
the output registers. At the end of the vshader, unpack the OUT temps
into the proper GL variables. At the beginning of the pshader, pack the
GL variables back into 12 IN registers.

Ivan Gyurdiev a42925ee09 wined3d: Register map cleanups.
Various cleanups:
- do not use DWORD as a bitmask, that places artificial limit of 32 on
  registers
- track attributes that are used and declare only those
- move declarations function call in pshader/vshader to allow us to
  insert pixel or vertex specific code between the declarations and
  the rest of the code
- remove redundant 0 intializers
- remove useless continue statement

Ivan Gyurdiev 17b0d26c1e wined3d: Share trace pass
Now that the declaration function is out of the way, the tracing pass,
which is very long and 100% the same can be shared between pixel and
vertex shaders.

The new function is called shader_trace_init(), and is responsible for:
- tracing the shader
- initializing the function length
- setting the shader version [needed very early]
2006-06-13 11:40:22 +02:00
Ivan Gyurdiev 9bae7755ab wined3d: Rework dcl processing.
The new function is called in pass 2 (getister counting/maps), and
it's now in baseshader. It operates on all INPUT and OUTPUT registers,
which, in addition to the old vertex shader input declarations covers
Shader Model 3.0 vshader output and pshader input declarations. The
result is stored into the reg_map structure.

Ivan Gyurdiev f144d58ac2 wined3d: The namedArrays code path is dead (always FALSE).
Delete the entire namedArrays code path and all its dependencies (one
of which is quite long - storeOrder in drawprim is always FALSE, for
example). Delete declaredArrays, and make its code path the default.

Jason Green e8c97e9421 wined3d: Fix regression from register maps switch for ARB shaders.
I missed a register mask in the move to share the shader_hw_def()
function between pixel and vertex shaders for ARB shaders.  Fixed
that, and made the GLSL version use the same mask for consistency.
2006-06-10 12:43:02 +02:00
Jason Green 806aaa1287 wined3d: Added more declarations to GLSL.
- Declare more variable names for GLSL programs.
- Some of these won't need to be declared eventually, but it doesn't hurt to do it for now.
- Correct output name for pixel shaders (gl_FragColor instead of glFragColor).
2006-06-09 15:14:22 +02:00
Jason Green ca70d13af4 wined3d: Unified float constant register mapping between ARB pixel and vertex shaders.
- Got rid of the separate constant maps.
- Side effect of this is that the map is a bit larger for pixel shaders than it needs to be
2006-06-09 14:36:50 +02:00
Jason Green 0c59ca6448 wined3d: Add the bulk of the GLSL string generation functions.
- Add a new file glsl_shader.c which contains almost every GLSL specific function we'll need
- Move print_glsl_info() into glsl_shader.c
- Move the shader_reg_maps struct info into the private header, and make it part of SHADER_OPCODE_ARG.
- Create a new shared ps/vs register map for float constants (future patch will make ARB programs use this, too)

Ivan Gyurdiev 42b89791ff wined3d: Take predication tokens into account.
Each instruction can have a predication token. Account for it in the
trace pass, register count pass, and store it in the SHADER_OPCODE_ARG
structure for generation. MSDN claims the token is at the end of the
instruction, but that's not true - testing a demo, which lets me
manipulate the shader shows the predication token is the first source
token immediately following the destination token.

Ivan Gyurdiev 746d1b1cd3 wined3d: Modify shader_dump_param() to take into account address token.
Currently we hardcode a0.x, which I think is correct for shaders 1.0.
However, for shaders 2.0, we must look into the address token, and
print the register there. Handle both cases to correct the trace.
2006-05-17 10:55:11 +02:00
Ivan Gyurdiev 03b67e3030 wined3d: Use shader_get_param() in trace pass, reg. count pass, generation pass.
Change the trace pass, the register counting pass, and the hw
generator pass to take into account the new get_params() function. For
hw generation, store the address tokens into the SHADER_OPCODE_ARG
structure, so they're available to generator functions.
2006-05-17 10:54:23 +02:00
Ivan Gyurdiev 404eff792f wined3d: Add shader_get_param() fn, which processes address tokens.
Add a new function to process parameters.
On shaders 1.0, processing parameters amounts to *pToken++.
On shaders 2.0+, we have a relative addressing token to account for.
This function should be used, instead of relying on num_params everywhere.
2006-05-17 10:53:18 +02:00
Ivan Gyurdiev 53d240a3e0 wined3d: Do not rely on num_params to skip unhandled tokens in shaders 2.0. 2006-05-17 10:52:37 +02:00

Ivan Gyurdiev c61af3af8d wined3d: Share shader_dump_ins_modifiers().
Share shader_dump_ins_modifiers(), and make vertex shaders use it.
The saturate modifer (_sat) is valid on vs_3_0+, and it isn't being
shown in the trace.
