1055 * each block has space for a maximum of 64 DWORDs, and this matches reported
1056 * native limits.
1057 *
1058 * The basic functional block seems to be one MAD for each color and alpha,
1059 * and an adder that adds all components after the MUL.
1060 * - ADD, MUL, MAD etc.: use MAD with appropriate neutral operands
1061 * - DP4: Use OUTC_DP4, OUTA_DP4
1062 * - DP3: Use OUTC_DP3, OUTA_DP4, appropriate alpha operands
1063 * - DPH: Use OUTC_DP4, OUTA_DP4, appropriate alpha operands
1064 * - CMPH: If ARG2 > 0.5, return ARG0, else return ARG1
1065 * - CMP: If ARG2 < 0, return ARG1, else return ARG0
1066 * - FLR: use FRC+MAD
1067 * - XPD: use MAD+MAD
1068 * - SGE, SLT: use MAD+CMP
1069 * - RSQ: use ABS modifier for argument
1070 * - Use OUTC_REPL_ALPHA to write results of an alpha-only operation
1071 * (e.g. RCP) into color register
1072 * - apparently, there's no quick DST operation
1073 * - fglrx set FPI2_UNKNOWN_31 on a "MAD fragment.color, tmp0, tmp1, tmp2"
1074 * - fglrx set FPI2_UNKNOWN_31 on a "MAX r2, r1, c0"
1075 * - fglrx once set FPI0_UNKNOWN_31 on a "FRC r1, r1"
1076 *
1077 * Operand selection
1078 * First stage selects three sources from the available registers and
1079 * constant parameters. This is defined in INSTR1 (color) and INSTR3 (alpha).
1080 * fglrx sorts the three source fields: Registers before constants,
1081 * lower indices before higher indices; I do not know whether this is
1082 * necessary.
1083 *
1084 * fglrx fills unused sources with "read constant 0"
1085 * According to specs, you cannot select more than two different constants.
1086 *
1087 * Second stage selects the operands from the sources. This is defined in
1088 * INSTR0 (color) and INSTR2 (alpha). You can also select the special constants
1089 * zero and one.
1090 * Swizzling and negation happens in this stage, as well.
1091 *
1092 * Important: Color and alpha seem to be mostly separate, i.e. their sources
1093 * selection appears to be fully independent (the register storage is probably
1094 * physically split into a color and an alpha section).
1095 * However (because of the apparent physical split), there is some interaction
1096 * WRT swizzling. If, for example, you want to load an R component into an
1097 * Alpha operand, this R component is taken from a *color* source, not from
1098 * an alpha source. The corresponding register doesn't even have to appear in
1099 * the alpha sources list. (I hope this all makes sense to you)
1100 *
1101 * Destination selection
1102 * The destination register index is in FPI1 (color) and FPI3 (alpha)
1103 * together with enable bits.
1104 * There are separate enable bits for writing into temporary registers
1105 * (DSTC_REG_* /DSTA_REG) and and program output registers (DSTC_OUTPUT_*
1106 * /DSTA_OUTPUT). You can write to both at once, or not write at all (the
1107 * same index must be used for both).
1108 *
1109 * Note: There is a special form for LRP
1110 * - Argument order is the same as in ARB_fragment_program.
1111 * - Operation is MAD
1112 * - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP
1113 * - Set FPI0/FPI2_SPECIAL_LRP
1114 * Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD

1577 /* Every instruction is four dwords long:
1578 * DWORD 0: output and opcode
1579 * DWORD 1: first argument
1580 * DWORD 2: second argument
1581 * DWORD 3: third argument
1582 *
1583 * Notes:
1584 * - ABS r, a is implemented as MAX r, a, -a
1585 * - MOV is implemented as ADD to zero
1586 * - XPD is implemented as MUL + MAD
1587 * - FLR is implemented as FRC + ADD
1588 * - apparently, fglrx tries to schedule instructions so that there is at
1589 * least one instruction between the write to a temporary and the first
1590 * read from said temporary; however, violations of this scheduling are
1591 * allowed
1592 * - register indices seem to be unrelated with OpenGL aliasing to
1593 * conventional state
1594 * - only one attribute and one parameter can be loaded at a time; however,
1595 * the same attribute/parameter can be used for more than one argument
1596 * - the second software argument for POW is the third hardware argument
1597 * (no idea why)
1598 * - MAD with only temporaries as input seems to use VPI_OUT_SELECT_MAD_2
1599 *
1600 * There is some magic surrounding LIT:
1601 * The single argument is replicated across all three inputs, but swizzled:
1602 * First argument: xyzy
1603 * Second argument: xyzx
1604 * Third argument: xyzw
1605 * Whenever the result is used later in the fragment program, fglrx forces
1606 * x and w to be 1.0 in the input selection; I don't know whether this is
1607 * strictly necessary
