2010-01-05tgsi: Make interpreter aware of float and integer data types.Michal Krol

2010-01-05gallium: Add UMOD TGSI opcode.Michal Krol
Either that or have UDIV have two destination operands.
2010-01-05gallium: Add SWITCH, CASE, DEFAULT and ENDSWITCH opcodes to TGSI.Michal Krol
Provide reference implementation of them in tgsi_exec. Note that BREAK opcode is overloaded and can be used to break out of either a loop or a switch-case statement.

2010-01-05tgsi: Implement new integer opcodes.Michal Krol
Update interpreter and ureg. Also, get rid of SHR -- it's actually an alias for ISHR.

2009-12-14tgsi: add properties and system value registerZack Rusin
adds support for properties to all parts of the tgsi framework, plus introduces a new register which will be used for system generated values.

2009-11-24tgsi: reduce repetition of structure name in its membersKeith Whitwell
Rename Semantic.SemanticName to Semantic.Name. Similar for SemanticIndex, and the members of the tgsi_version struct.
2009-11-24gallium: simplify tgsi tokens furtherKeith Whitwell
Drop anonymous 'Extended' fields, have every optional token named explicitly in its parent. Eg. there is now an Instruction.Label flag, etc. Drop destination modifiers and other functionality which cannot be generated by tgsi_ureg.c, which is now the primary way of creating shaders. Pull source modifiers into the source register token, drop the second negate flag. The source register token is now full - if we need to expand it, probably best to move all of the modifiers to a new token and have a single flag for it.

2009-10-23gallium: remove the swizzling parts of ExtSwizzleKeith Whitwell
These haven't been used by the mesa state tracker since the conversion to tgsi_ureg, and it seems that none of the other state trackers are using it either. This helps simplify one of the biggest suprises when starting off with TGSI shaders.
2009-10-23gallium: remove noise opcodesKeith Whitwell
Provide a dummy implementation in the GL state tracker (move 0.5 to the destination regs). At some point, a motivated person could add a better implementation of noise. Currently not even the nvidia binary drivers do anything more than this. In any case, the place to do this is in the GL state tracker, not the poor driver.
2009-09-10tgsi: use new tgsi_call_record to handle execution mask stacksBrian Paul
This fixes some issues when "return"ing from nested loops/conditionals.
2009-09-03aux/tgsi: pull back ureg work from 0.1 branchKeith Whitwell
Manual merge of ureg changes on the branch. Too much unrelated stuff for a proper merge.
2009-09-01tgsi: remove redundant CND0 opcodeKeith Whitwell
Can be implemented with CMP src2, src1, src0
2009-08-20tgsi: handle SOA dependencies for MOV/SWZBrian Paul
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.
2009-08-17gallium: memset() tgsi_exec_machine to all zeros in tgsi_exec_machine_create()Brian Paul
This fixes invalid values for CondStackTop, LoopStackTop, etc.
2009-07-31Rename TGSI LOOP instruction to better match theri usage.Michal Krol
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.
2009-07-23gallium: remove deprecated TGSI opcodesKeith Whitwell
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.
2009-07-22gallium: remove multiple aliases for TGSI opcodesKeith Whitwell
This is a source of ongoing confusion. TGSI has multiple names for opcodes where the same semantics originate in multiple shader APIs. For instance, TGSI includes both Mesa/GLSL and DX/SM30 names for opcodes with the same semantics, but aliases those names to the same underlying opcode number. This makes it very difficult to visually inspect two sets of opcodes (eg in state tracker & driver) and check if they implement the same functionality. This patch arbitarily rips out the versions of the opcodes not currently favoured by the mesa state tracker and leaves us with a single name for each distinct operation.
2009-07-22gallium: simplify tgsi_full_immediate structKeith Whitwell
Remove the need to have a pointer in this struct by just including the immediate data inline. Having a pointer in the struct introduces complications like needing to alloc/free the data pointed to, uncertainty about who owns the data, etc. There doesn't seem to be a need for it, and it is unlikely to make much difference plus or minus to performance. Added some asserts as we now will trip up on immediates with more than four elements. There were actually already quite a few such asserts, but the >4 case could be used in the future to specify indexable immediate ranges, such as lookup tables.
