1034  *  - DP3: Use OUTC_DP3, OUTA_DP4, appropriate alpha operands
1035  *  - DPH: Use OUTC_DP4, OUTA_DP4, appropriate alpha operands
1036  *  - CMPH: If ARG2 > 0.5, return ARG0, else return ARG1
1037  *  - CMP: If ARG2 < 0, return ARG1, else return ARG0
1038  *  - FLR: use FRC+MAD
1039  *  - XPD: use MAD+MAD
1040  *  - SGE, SLT: use MAD+CMP
1041  *  - RSQ: use ABS modifier for argument
1042  *  - Use OUTC_REPL_ALPHA to write results of an alpha-only operation
1043  *    (e.g. RCP) into color register
1044  *  - apparently, there's no quick DST operation
1045  *  - fglrx set FPI2_UNKNOWN_31 on a "MAD fragment.color, tmp0, tmp1, tmp2"
1046  *  - fglrx set FPI2_UNKNOWN_31 on a "MAX r2, r1, c0"
1047  *  - fglrx once set FPI0_UNKNOWN_31 on a "FRC r1, r1"
1048  *
1049  * Operand selection
1050  * First stage selects three sources from the available registers and
1051  * constant parameters. This is defined in INSTR1 (color) and INSTR3 (alpha).
1052  * fglrx sorts the three source fields: Registers before constants,
1053  * lower indices before higher indices; I do not know whether this is
1054  * necessary.
1055  *
1056  * fglrx fills unused sources with "read constant 0"
1057  * According to specs, you cannot select more than two different constants.
1058  *
1059  * Second stage selects the operands from the sources. This is defined in
1060  * INSTR0 (color) and INSTR2 (alpha). You can also select the special constants
1061  * zero and one.
1062  * Swizzling and negation happens in this stage, as well.
1063  *
1064  * Important: Color and alpha seem to be mostly separate, i.e. their sources
1065  * selection appears to be fully independent (the register storage is probably
1066  * physically split into a color and an alpha section).
1067  * However (because of the apparent physical split), there is some interaction
1068  * WRT swizzling. If, for example, you want to load an R component into an
1069  * Alpha operand, this R component is taken from a *color* source, not from
1070  * an alpha source. The corresponding register doesn't even have to appear in
1071  * the alpha sources list. (I hope this all makes sense to you)
1072  *
1073  * Destination selection
1074  * The destination register index is in FPI1 (color) and FPI3 (alpha)
1075  * together with enable bits.
1076  * There are separate enable bits for writing into temporary registers
1077  * (DSTC_REG_* /DSTA_REG) and and program output registers (DSTC_OUTPUT_*
1078  * /DSTA_OUTPUT). You can write to both at once, or not write at all (the
1079  * same index must be used for both).
1080  *
1081  * Note: There is a special form for LRP
1082  *  - Argument order is the same as in ARB_fragment_program.
1083  *  - Operation is MAD
1084  *  - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP
1085  *  - Set FPI0/FPI2_SPECIAL_LRP
1086  * Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD

1449  *  - FLR is implemented as FRC + ADD
1450  *  - apparently, fglrx tries to schedule instructions so that there is at
1451  *    least one instruction between the write to a temporary and the first
1452  *    read from said temporary; however, violations of this scheduling are
1453  *    allowed

1456  *  - only one attribute and one parameter can be loaded at a time; however,
1457  *    the same attribute/parameter can be used for more than one argument
1458  *  - the second software argument for POW is the third hardware argument

1466  *     Third argument: xyzw
1467  *   Whenever the result is used later in the fragment program, fglrx forces
1468  *   x and w to be 1.0 in the input selection; I don't know whether this is
1469  *   strictly necessary
