#define NV50_SU_MAX_TEMP 64
/* ARL
* DST - const(1.0)
* LIT
* LIT - other buggery
* POW
* SWZ
* SWZ - negation ARGH
* SAT
*
* MSB - Like MAD, but MUL+SUB
* - Fuck it off, introduce a way to negate args for ops that
* support it.
*
* Need ability to specifiy driver IMMD values, like nv40 constant()
*
* Look into inlining IMMD for ops other than MOV
* - Maybe even relax restrictions a bit, can't do P_RESULT + P_IMMD,
* but can emit to P_TEMP first - then MOV later. NVIDIA does this
