| | | | Values outside the writemask are set in the destination to {0,0,0,1}
* aux/tgsi: pull back ureg work from 0.1 branchKeith Whitwell2009-09-0311-174/+429
| | | | | 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
* util: Auto generate pixel format accessor functions fromJosé Fonseca2009-08-308-93/+699
| | | | | | | | | | | | This has several advantages over the u_ - not hand written - no intermediate memcpy of raw pixels - supports 4 ubytes in addition to floats - no need to pass a pipe_transfer It also has (hopefully temporary) limitations: - no support for YUV - no support for SRGB

| | | | | | | | | | Namelly, explicitly distinguish formats coded by arithmetic manipulation, from formats layed out in array.
* | util: Don't commit u_format_table.cJosé Fonseca2009-08-292-1925/+1
| | | | | | | | At least not until stabilizes, to reduce noise.

* | util: Pixel format database.José Fonseca2009-08-297-0/+2397
| | | | | | | | | | | | | | There are some inconsistencies in pipe_format, but above all, there simply aren't enough bits in an enum to conveniently store all information about a pixel format we need to be able to dynamically generate pixel packing/unpacking code.

| * 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/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | 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: 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.

| | | | | | | | | | | | | | | | This previously was used only for decomposed (POINT/LINE/TRI) primitives, but for some time a full range of primitives could end up in here. Fixes trivial/lineloop-clip on softpipe, among others. (cherry picked from commit 87cd8a3b8a2407b30916be418ff2f95dfea5d2ad)
