42 * MSB - Like MAD, but MUL+SUB
43 * - Fuck it off, introduce a way to negate args for ops that
46 * Look into inlining IMMD for ops other than MOV (make it general?)
47 * - Maybe even relax restrictions a bit, can't do P_RESULT + P_IMMD,
48 * but can emit to P_TEMP first - then MOV later. NVIDIA does this
50 * In ops such as ADD it's possible to construct a bad opcode in the !is_long()
51 * case, if the emit_src() causes the inst to suddenly become long.
53 * Verify half-insns work where expected - and force disable them where they
54 * don't work - MUL has it forcibly disabled atm as it fixes POW..
56 * FUCK! watch dst==src vectors, can overwrite components that are needed.
57 * ie. SUB R0, R0.yzxw, R0
59 * Things to check with renouveau:
60 * FP attr/result assignment - how?
62 * - 0x16bc maps vp output onto fp hpos
63 * - 0x16c0 maps vp output onto fp col0
67 * 0x16bc->0x16e8 --> some binding between vp/fp regs
68 * 0x16b8 --> VP output count
70 * 0x1298 --> "MOV rcol.x, fcol.y" "MOV depr, fcol.y" = 0x00000005
71 * "MOV rcol.x, fcol.y" = 0x00000004
72 * 0x19a8 --> as above but 0x00000100 and 0x00000000
73 * - 0x00100000 used when KIL used
74 * 0x196c --> as above but 0x00000011 and 0x00000000
76 * 0x1988 --> 0xXXNNNNNN
77 * - XX == FP high something
