- * 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
