| * tgsi/sse: Pass the lodbias, not zero. More comments.Brian Paul2009-09-241-5/+5
| | | | | | | | This fixes the glean/glsl1 "texture2D(), with bias" test when using SSE.

* | tgsi: handle some src/dst aliasing in tgsi_sse2.cKeith Whitwell2009-09-131-8/+23
| | | | | | | | | | | | | | | | | | | | | | | | Src/Dst aliasing (aka SOA dependencies) requires some care to ensure intermediate results do not overwrite yet-to-be read source registers. This change ensures that MOV/SWZ handle this correctly, which is poor but no worse than the current tgsi_exec.c path. Remove the fallback as there is nothing to be gained correctness-wise between the two implementations now. Fixing this properly looks like a bit of work in this code, but might be easily achieved by sending destination writes to temporary storage.
* | tgsi: implement saturationKeith Whitwell2009-09-121-17/+26
| | | | | | | | Fix recent performance regression.
* | tgsi: add missing implementation of constant decl changeKeith Whitwell2009-09-121-8/+61
| |
* | ureg: add a mechanism to get the built tokens rather than a full shaderKeith Whitwell2009-09-122-0/+30
| | | | | | | | | | | | Previously ureg would always call the driver's create-shader function. This allows the caller the opportunity to hold onto the tokens if it needs to reuse them, eg. to create an internal draw shader.
* | ureg: add generic emitters for tex and branch instructionsKeith Whitwell2009-09-122-11/+80
| | | | | | | | Couldn't previously emit these except by calling the opcode-specific helper.
* | tgsi/ureg: give ureg_DECL_constant an explicit index parameterKeith Whitwell2009-09-122-2/+6
| | | | | | | | | | Avoid the need to emit all constant declarations in order. Makes referring to a specific constant in the constant buffer much easier.
* | tgsi/ureg: VS inputs don't have any semantic tags, just an indexKeith Whitwell2009-09-122-38/+37
| | | | | | | | Fix ureg_DECL_vs_input to reflect this and fix up all callers.

* tgsi: use new tgsi_call_record to handle execution mask stacksBrian Paul2009-09-102-14/+43
| | | | This fixes some issues when "return"ing from nested loops/conditionals.
* tgsi: Document differencies between vs_1_1 and vs_2_0 for EXPP and LOGP.Michal Krol2009-09-041-2/+12

* aux/tgsi: pull back ureg work from 0.1 branchKeith Whitwell2009-09-039-173/+424
| | | | | Manual merge of ureg changes on the branch. Too much unrelated stuff for a proper merge.
* tgsi: remove redundant CND0 opcodeKeith Whitwell2009-09-015-21/+2
| | | | Can be implemented with CMP src2, src1, src0
* tgsi: Only free temp uregs.José Fonseca2009-08-241-2/+3
| | | | | Shorthand. (cherry picked from commit de911220bbbe74cff0c79b260456ff36122b7b5b)
* tgsi: Pass pipe_context as a parameter to ureg_create_shader.José Fonseca2009-08-242-14/+30
| | | | | Simplifies migration to tgsi_ureg. (cherry picked from commit f574398c07c41cb8d31249a7186fc178ef7d552a)
* tgsi: add generic instruction builderKeith Whitwell2009-08-242-0/+33
| | | | | | When translating an incoming shader (rather than building one from scratch) it's preferable to be able to call a single, generic instruction emitter rather than figuring out which of the opcode-specific functions to call.
* tgsi: when printing/dumping programs indent loops and conditionalsBrian Paul2009-08-201-0/+35

* tgsi: check for SOA dependencies in SSE and PPC code generatorsBrian Paul2009-08-202-0/+8
| | | | Fall back to interpreter for now. This doesn't happen very often.
* tgsi: handle SOA dependencies for MOV/SWZBrian Paul2009-08-202-14/+44
| | | | | | | | | | | | | | | | | | | | | | SOA dependencies can happen when a register is used both as a source and destination and the source is swizzled. For example: MOV T, T.yxwz; would expand into: MOV t0, t1; MOV t1, t0; MOV t2, t3; MOV t3, t2; The second instruction will produce the wrong result since we wrote to t0 in the first instruction. We need to use an intermediate temporary to fix this. This will take more work to fix for all TGSI instructions. This seems to happen with MOV instructions more than anything else so fix that case now and warn on others. Fixes piglit glsl-vs-loop test (when not using SSE). See bug 23317.
* tgsi: added tgsi_full_instruction::Flags fieldBrian Paul2009-08-202-0/+3
| | | | Users of the parser can make use of this.
* tgsi: Add missing include.José Fonseca2009-08-191-0/+1

* tgsi: Fix typo in ureg constant creation.José Fonseca2009-08-191-1/+1

* tgsi: remove unused function argumentKeith Whitwell2009-08-191-4/+2
|
* tgsi: add missing functionality to support instructions with labelsKeith Whitwell2009-08-192-1/+57
| | | | | | | | | | | | | | | | Could previously emit opcodes with label arguments, but was no way to patch them with the actual destinations of those labels. Adds two functions: ureg_get_instruction_number - to get the id of the next instruction to be emitted ureg_fixup_label - to patch an emitted label to point to a given instruction number. Need some more complex examples than u_simple_shader, so far this has only been compile-tested.

* | tgsi: add tgsi_ureg, a simplified tgsi shader builderKeith Whitwell2009-08-135-0/+1381
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is modelled on the nice & easy-to-use facilities we had for building shaders in mesa, eg. in texenvprogram.c and friends. Key points include pass-by-value register structs that can be manipulated in a functional style, eg: negate(swizzle(reg, X,X,X,X)) and per-opcode instruction functions, eg: emit_MOV( p, writemask(dst, 0x1), negate(src)); and similar. Additionally, the interface allows mixed emit of instructions and decls, which are sorted out internally to obey TGSI ordering. Immediates may be emitted at any time and are scanned against existing immediates to try and reduce redundancy. Not all TGSI functionality is accessible through this interface, but most or all of what mesa uses should be.

| | | | | | | | | | | | | | | | The LOOP/ENDLOOP pair is renamed to BGNFOR/ENDFOR as its behaviour is similar to a C language for-loop. The BGNLOOP2/ENDLOOP2 pair is renamed to BGNLOOP/ENDLOOP as now there is no name collision.

| | | | | | | | | | | | | | The only valid usage for LOOP/ENDLOOP instructions is LOOP[0] as a destination register. The only valid usage for the remaining instructions is LOOP[0].x as an indirect register.

* | gallium: fix SSE shadow texture instructionsBrian Paul2009-07-291-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When sampling a 2D shadow map we need 3 texcoord components, not 2. The third component (distance from light source) is compared against the texture sample to return the result (visible vs. occluded). Also, enable proper handling of TGSI_TEXTURE_SHADOW targets in Mesa->TGSI translation. There's a possibility for breakage in gallium drivers if they fail to handle the TGSI_TEXTURE_SHADOW1D / TGSI_TEXTURE_SHADOW2D / TGSI_TEXTURE_SHADOWRECT texture targets for TGSI_OPCODE_TEX/TXP instructions, but that should be easy to fix. With these changes, progs/demos/shadowtex.c renders properly again with softpipe.
* | gallium: remove deprecated TGSI opcodesKeith Whitwell2009-07-233-34/+7
| | | | | | | | | | | | Various opcodes which can be implemented trivially with other TGSI opcodes, such as matrix multiplication and negation. These were not used by any state tracker or implemented by any of the drivers.
