|
|
* The corresponding input is routed into the register with the given index.
|

|
|
* - DP3: Use OUTC_DP3, OUTA_DP4, appropriate alpha operands
|
|
* - DPH: Use OUTC_DP4, OUTA_DP4, appropriate alpha operands
|
|
* - CMPH: If ARG2 > 0.5, return ARG0, else return ARG1
|
|
* - 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 all 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

* DWORD 1: first argument
|

|

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