37/* ARL - gallium craps itself on progs/vp/arl.txt
38 *
39 * MSB - Like MAD, but MUL+SUB
40 * 	- Fuck it off, introduce a way to negate args for ops that
41 * 	  support it.
42 *
43 * Look into inlining IMMD for ops other than MOV (make it general?)
44 * 	- Maybe even relax restrictions a bit, can't do P_RESULT + P_IMMD,
45 * 	  but can emit to P_TEMP first - then MOV later. NVIDIA does this
46 *
47 * In ops such as ADD it's possible to construct a bad opcode in the !is_long()
48 * case, if the emit_src() causes the inst to suddenly become long.
49 *
50 * Verify half-insns work where expected - and force disable them where they
51 * don't work - MUL has it forcibly disabled atm as it fixes POW..
52 *
53 * FUCK! watch dst==src vectors, can overwrite components that are needed.
54 * 	ie. SUB R0, R0.yzxw, R0
55 *
56 * Things to check with renouveau:
57 * 	FP attr/result assignment - how?
58 * 		attrib
59 * 			- 0x16bc maps vp output onto fp hpos
60 * 			- 0x16c0 maps vp output onto fp col0
61 * 		result
62 * 			- colr always 0-3
63 * 			- depr always 4
64 * 0x16bc->0x16e8 --> some binding between vp/fp regs
65 * 0x16b8 --> VP output count
66 *
67 * 0x1298 --> "MOV rcol.x, fcol.y" "MOV depr, fcol.y" = 0x00000005
68 * 	      "MOV rcol.x, fcol.y" = 0x00000004
69 * 0x19a8 --> as above but 0x00000100 and 0x00000000
70 * 	- 0x00100000 used when KIL used
71 * 0x196c --> as above but 0x00000011 and 0x00000000
72 *
73 * 0x1988 --> 0xXXNNNNNN
74 * 	- XX == FP high something
