1054 * each block has space for a maximum of 64 DWORDs, and this matches reported
1057 * The basic functional block seems to be one MAD for each color and alpha,
1058 * and an adder that adds all components after the MUL.
1059 * - ADD, MUL, MAD etc.: use MAD with appropriate neutral operands
1060 * - DP4: Use OUTC_DP4, OUTA_DP4
1061 * - DP3: Use OUTC_DP3, OUTA_DP4, appropriate alpha operands
1062 * - DPH: Use OUTC_DP4, OUTA_DP4, appropriate alpha operands
1063 * - CMPH: If ARG2 > 0.5, return ARG0, else return ARG1
1064 * - CMP: If ARG2 < 0, return ARG1, else return ARG0
1065 * - FLR: use FRC+MAD
1066 * - XPD: use MAD+MAD
1067 * - SGE, SLT: use MAD+CMP
1068 * - RSQ: use ABS modifier for argument
1069 * - Use OUTC_REPL_ALPHA to write results of an alpha-only operation
1070 * (e.g. RCP) into color register
1071 * - apparently, there's no quick DST operation
1072 * - fglrx set FPI2_UNKNOWN_31 on a "MAD fragment.color, tmp0, tmp1, tmp2"
1073 * - fglrx set FPI2_UNKNOWN_31 on a "MAX r2, r1, c0"
1074 * - fglrx once set FPI0_UNKNOWN_31 on a "FRC r1, r1"
1077 * First stage selects three sources from the available registers and
1078 * constant parameters. This is defined in INSTR1 (color) and INSTR3 (alpha).
1079 * fglrx sorts the three source fields: Registers before constants,
1080 * lower indices before higher indices; I do not know whether this is
1083 * fglrx fills unused sources with "read constant 0"
1084 * According to specs, you cannot select more than two different constants.
1086 * Second stage selects the operands from the sources. This is defined in
1087 * INSTR0 (color) and INSTR2 (alpha). You can also select the special constants
1089 * Swizzling and negation happens in this stage, as well.
1091 * Important: Color and alpha seem to be mostly separate, i.e. their sources
1092 * selection appears to be fully independent (the register storage is probably
1093 * physically split into a color and an alpha section).
1094 * However (because of the apparent physical split), there is some interaction
1095 * WRT swizzling. If, for example, you want to load an R component into an
1096 * Alpha operand, this R component is taken from a *color* source, not from
1097 * an alpha source. The corresponding register doesn't even have to appear in
1098 * the alpha sources list. (I hope this all makes sense to you)
1100 * Destination selection
1101 * The destination register index is in FPI1 (color) and FPI3 (alpha)
1102 * together with enable bits.
1103 * There are separate enable bits for writing into temporary registers
1104 * (DSTC_REG_* /DSTA_REG) and and program output registers (DSTC_OUTPUT_*
1105 * /DSTA_OUTPUT). You can write to both at once, or not write at all (the
1106 * same index must be used for both).
1108 * Note: There is a special form for LRP
1109 * - Argument order is the same as in ARB_fragment_program.
1110 * - Operation is MAD
1111 * - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP
1112 * - Set FPI0/FPI2_SPECIAL_LRP
1113 * Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD

1589 * read from said temporary; however, violations of this scheduling are
1591 * - register indices seem to be unrelated with OpenGL aliasing to
1592 * conventional state
