1055 * in which fglrx. I assume there is space for 64 instructions, since
1056 * each block has space for a maximum of 64 DWORDs, and this matches reported
1057 * native limits.
1058 *
1059 * The basic functional block seems to be one MAD for each color and alpha,
1060 * and an adder that adds all components after the MUL.
1061 * - ADD, MUL, MAD etc.: use MAD with appropriate neutral operands
1062 * - DP4: Use OUTC_DP4, OUTA_DP4
1063 * - DP3: Use OUTC_DP3, OUTA_DP4, appropriate alpha operands
1064 * - DPH: Use OUTC_DP4, OUTA_DP4, appropriate alpha operands
1065 * - CMPH: If ARG2 > 0.5, return ARG0, else return ARG1
1066 * - CMP: If ARG2 < 0, return ARG1, else return ARG0
1067 * - FLR: use FRC+MAD
1068 * - XPD: use MAD+MAD
1069 * - SGE, SLT: use MAD+CMP
1070 * - RSQ: use ABS modifier for argument
1071 * - Use OUTC_REPL_ALPHA to write results of an alpha-only operation
1072 * (e.g. RCP) into color register
1073 * - apparently, there's no quick DST operation
1074 * - fglrx set FPI2_UNKNOWN_31 on a "MAD fragment.color, tmp0, tmp1, tmp2"
1075 * - fglrx set FPI2_UNKNOWN_31 on a "MAX r2, r1, c0"
1076 * - fglrx once set FPI0_UNKNOWN_31 on a "FRC r1, r1"
1077 *
1078 * Operand selection
1079 * First stage selects three sources from the available registers and
1080 * constant parameters. This is defined in INSTR1 (color) and INSTR3 (alpha).
1081 * fglrx sorts the three source fields: Registers before constants,
1082 * lower indices before higher indices; I do not know whether this is
1083 * necessary.
1084 *
1085 * fglrx fills unused sources with "read constant 0"
1086 * According to specs, you cannot select more than two different constants.
1087 *
1088 * Second stage selects the operands from the sources. This is defined in
1089 * INSTR0 (color) and INSTR2 (alpha). You can also select the special constants
1090 * zero and one.
1091 * Swizzling and negation happens in this stage, as well.
1092 *
1093 * Important: Color and alpha seem to be mostly separate, i.e. their sources
1094 * selection appears to be fully independent (the register storage is probably
1095 * physically split into a color and an alpha section).
1096 * However (because of the apparent physical split), there is some interaction
1097 * WRT swizzling. If, for example, you want to load an R component into an
1098 * Alpha operand, this R component is taken from a *color* source, not from
1099 * an alpha source. The corresponding register doesn't even have to appear in
1100 * the alpha sources list. (I hope this all makes sense to you)
1101 *
1102 * Destination selection
1103 * The destination register index is in FPI1 (color) and FPI3 (alpha)
1104 * together with enable bits.
1105 * There are separate enable bits for writing into temporary registers
1106 * (DSTC_REG_* /DSTA_REG) and and program output registers (DSTC_OUTPUT_*
1107 * /DSTA_OUTPUT). You can write to both at once, or not write at all (the
1108 * same index must be used for both).
1109 *
1110 * Note: There is a special form for LRP
1111 * - Argument order is the same as in ARB_fragment_program.
1112 * - Operation is MAD
1113 * - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP
1114 * - Set FPI0/FPI2_SPECIAL_LRP
1115 * Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD

1582 * DWORD 0: output and opcode

1585 * DWORD 3: third argument
1586 *
1587 * Notes:
1588 * - ABS r, a is implemented as MAX r, a, -a
1589 * - MOV is implemented as ADD to zero
1590 * - XPD is implemented as MUL + MAD
1591 * - FLR is implemented as FRC + ADD
1592 * - apparently, fglrx tries to schedule instructions so that there is at
1593 * least one instruction between the write to a temporary and the first
1594 * read from said temporary; however, violations of this scheduling are
1595 * allowed
1596 * - register indices seem to be unrelated with OpenGL aliasing to
1597 * conventional state
1598 * - only one attribute and one parameter can be loaded at a time; however,
1599 * the same attribute/parameter can be used for more than one argument
1600 * - the second software argument for POW is the third hardware argument
1601 * (no idea why)
1602 * - MAD with only temporaries as input seems to use VPI_OUT_SELECT_MAD_2
1603 *
1604 * There is some magic surrounding LIT:
1605 * The single argument is replicated across all three inputs, but swizzled:
1606 * First argument: xyzy
1607 * Second argument: xyzx
1608 * Third argument: xyzw
1609 * Whenever the result is used later in the fragment program, fglrx forces
1610 * x and w to be 1.0 in the input selection; I don't know whether this is
1611 * strictly necessary
