2009-11-04tgsi/ureg: Allow for multiple extended instruction tokens.Michal Krol
For example, we would like to have a predicate and texture token in one instruction to do predicated texture sampling.
2009-11-02tgsi/ureg: Add negate and swizzle for predicates.Michal Krol
2009-11-02tgsi/ureg: Update for gallium interface changes.Michal Krol
2009-09-12ureg: add a mechanism to get the built tokens rather than a full shaderKeith Whitwell
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.
2009-09-12ureg: add generic emitters for tex and branch instructionsKeith Whitwell
Couldn't previously emit these except by calling the opcode-specific helper.
2009-09-12tgsi/ureg: give ureg_DECL_constant an explicit index parameterKeith Whitwell
Avoid the need to emit all constant declarations in order. Makes referring to a specific constant in the constant buffer much easier.
2009-09-12tgsi/ureg: VS inputs don't have any semantic tags, just an indexKeith Whitwell
Fix ureg_DECL_vs_input to reflect this and fix up all callers.
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.
2009-08-24tgsi: Pass pipe_context as a parameter to ureg_create_shader.José Fonseca
Simplifies migration to tgsi_ureg. (cherry picked from commit f574398c07c41cb8d31249a7186fc178ef7d552a)
2009-08-24tgsi: add generic instruction builderKeith Whitwell
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.
2009-08-19tgsi: add missing functionality to support instructions with labelsKeith Whitwell
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.
2009-08-13tgsi: add simple facility for releasing and reusing temporariesKeith Whitwell
2009-08-13tgsi: rename ureg src/dest convertersKeith Whitwell
Also fix a typo in ureg_src().
2009-08-13tgsi: add tgsi_ureg, a simplified tgsi shader builderKeith Whitwell
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.
