2010-05-14gallium: convert rasterizer state to use gl-style front/back conceptsKeith Whitwell
Use front/back instead of cw/ccw throughout. Also, use offset_point/line/fill instead of offset_cw/ccw. Brings gallium representation of this state into line with its main user, and also what turns out to be the most common hardware representation. This fixes a long-standing bias in the interface towards the architecture of the software rasterizer.

2010-02-22svga: Emit a scalar rcp in shadow maps.José Fonseca
Small improvement in Lightsmark 2008.
2010-02-22svga: Don't emit zero writemasks.José Fonseca
This fixes a regression with Lightsmark, where more compact TGSI from Mesa was causing a zero mask MOV to be emitted for shadow map compare, causing problems in some backends. Add a few more assertions to catch cases like this.

2010-02-03svga: fix TXD and TXL opcode translationKeith Whitwell
2010-02-03svga: deriv insns not valid in dynamic flow control eitherKeith Whitwell
2010-02-03svga: texture from lod zero inside dynamic branchingKeith Whitwell
Texture derivatives are potentially undefined inside dynamic branches, so hardwire lod zero in this case. Treating all if/endif and loop constructs as dynamic branches.
2010-02-03svga: better method for generating white fs color outputsKeith Whitwell
2010-01-05Remove TGSI_OPCODE_SHR, map existing usage to TGSI_OPCODE_ISHR.Michal Krol
This is to differentiate it from its unsigned version, TGSI_OPCODE_USHR.

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.
