/* BEGIN: Vertex program instruction set
// Every instruction is four dwords long:
//  DWORD 0: output and opcode
//  DWORD 1: first argument
//  DWORD 2: second 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 */
