5 This file contains registers and constants for the R300. They have been
6 found mostly by examining command buffers captured using glxtest, as well
7 as by extrapolating some known registers and constants from the R200.
9 I am fairly certain that they are correct unless stated otherwise in comments.

791 // - Use OUTC_REPL_ALPHA to write results of an alpha-only operation (e.g. RCP)
792 // into color register
793 // - apparently, there's no quick DST operation
794 // - fglrx set FPI2_UNKNOWN_31 on a "MAD fragment.color, tmp0, tmp1, tmp2"
795 // - fglrx set FPI2_UNKNOWN_31 on a "MAX r2, r1, c0"

801 // fglrx sorts the three source fields: Registers before constants,
802 // lower indices before higher indices; I do not know whether this is necessary.
803 // fglrx fills unused sources with "read constant 0"
804 // According to specs, you cannot select more than two different constants.
806 // Second stage selects the operands from the sources. This is defined in
807 // INSTR0 (color) and INSTR2 (alpha). You can also select the special constants
809 // Swizzling and negation happens in this stage, as well.
811 // Important: Color and alpha seem to be mostly separate, i.e. their sources
812 // selection appears to be fully independent (the register storage is probably
813 // physically split into a color and an alpha section).
814 // However (because of the apparent physical split), there is some interaction
815 // WRT swizzling. If, for example, you want to load an R component into an
816 // Alpha operand, this R component is taken from a *color* source, not from
817 // an alpha source. The corresponding register doesn't even have to appear in
818 // the alpha sources list. (I hope this alll makes sense to you)
820 // Destination selection
821 // The destination register index is in FPI1 (color) and FPI3 (alpha) together
823 // There are separate enable bits for writing into temporary registers
824 // (DSTC_REG_* /DSTA_REG) and and program output registers (DSTC_OUTPUT_* /DSTA_OUTPUT).
825 // You can write to both at once, or not write at all (the same index
826 // must be used for both).
828 // Note: There is a special form for LRP
829 // - Argument order is the same as in ARB_fragment_program.
830 // - Operation is MAD
831 // - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP
832 // - Set FPI0/FPI2_SPECIAL_LRP
833 // Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD */
