| /* ALU |
| // The ALU instructions register blocks are enumerated according to the order |
| // in which fglrx. I assume there is space for 64 instructions, since |
| // each block has space for a maximum of 64 DWORDs, and this matches reported |
| // native limits. |
| // |
| // The basic functional block seems to be one MAD for each color and alpha, |
| // and an adder that adds all components after the MUL. |
| // - ADD, MUL, MAD etc.: use MAD with appropriate neutral operands |
| // - DP4: Use OUTC_DP4, OUTA_DP4 |
| // - DP3: Use OUTC_DP3, OUTA_DP4, appropriate alpha operands |
| // - DPH: Use OUTC_DP4, OUTA_DP4, appropriate alpha operands |
| // - CMP: If ARG2 < 0, return ARG1, else return ARG0 |
| // - FLR: use FRC+MAD |
| // - XPD: use MAD+MAD |
| // - SGE, SLT: use MAD+CMP |
| // - RSQ: use ABS modifier for argument |
| // - Use OUTC_REPL_ALPHA to write results of an alpha-only operation (e.g. RCP) |
| // into color register |
| // - apparently, there's no quick DST operation |
| // - fglrx set FPI2_UNKNOWN_31 on a "MAD fragment.color, tmp0, tmp1, tmp2" |
| // - fglrx set FPI2_UNKNOWN_31 on a "MAX r2, r1, c0" |
| // - fglrx once set FPI0_UNKNOWN_31 on a "FRC r1, r1" |
| // |
| // Operand selection |
| // First stage selects three sources from the available registers and |
| // constant parameters. This is defined in INSTR1 (color) and INSTR3 (alpha). |
| // fglrx sorts the three source fields: Registers before constants, |
| // lower indices before higher indices; I do not know whether this is necessary. |
| // fglrx fills unused sources with "read constant 0" |
| // According to specs, you cannot select more than two different constants. |
| // |
| // Second stage selects the operands from the sources. This is defined in |
| // INSTR0 (color) and INSTR2 (alpha). You can also select the special constants |
| // zero and one. |
| // Swizzling and negation happens in this stage, as well. |
| // |
| // Important: Color and alpha seem to be mostly separate, i.e. their sources |
| // selection appears to be fully independent (the register storage is probably |
| // physically split into a color and an alpha section). |
| // However (because of the apparent physical split), there is some interaction |
| // WRT swizzling. If, for example, you want to load an R component into an |
| // Alpha operand, this R component is taken from a *color* source, not from |
| // an alpha source. The corresponding register doesn't even have to appear in |
| // the alpha sources list. (I hope this alll makes sense to you) |
| // |
| // Destination selection |
| // The destination register index is in FPI1 (color) and FPI3 (alpha) together |
| // with enable bits. |
| // There are separate enable bits for writing into temporary registers |
| // (DSTC_REG_* /DSTA_REG) and and program output registers (DSTC_OUTPUT_* /DSTA_OUTPUT). |
| // You can write to both at once, or not write at all (the same index |
| // must be used for both). |
| // |
| // Note: There is a special form for LRP |
| // - Argument order is the same as in ARB_fragment_program. |
| // - Operation is MAD |
| // - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP |
| // - Set FPI0/FPI2_SPECIAL_LRP |
| // Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD */ |
