- *
- * MSB - Like MAD, but MUL+SUB
- * 	- Fuck it off, introduce a way to negate args for ops that
- * 	  support it.
- *
- * Look into inlining IMMD for ops other than MOV (make it general?)
- * 	- 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
- *
- * In ops such as ADD it's possible to construct a bad opcode in the !is_long()
- * case, if the emit_src() causes the inst to suddenly become long.
- *
- * Verify half-insns work where expected - and force disable them where they
- * don't work - MUL has it forcibly disabled atm as it fixes POW..
- *
- * FUCK! watch dst==src vectors, can overwrite components that are needed.
- * 	ie. SUB R0, R0.yzxw, R0
- *
- * Things to check with renouveau:
- * 	FP attr/result assignment - how?
- * 		attrib
- * 			- 0x16bc maps vp output onto fp hpos
- * 			- 0x16c0 maps vp output onto fp col0
- * 		result
- * 			- colr always 0-3
- * 			- depr always 4
- * 0x16bc->0x16e8 --> some binding between vp/fp regs
- * 0x16b8 --> VP output count
- *
- * 0x1298 --> "MOV rcol.x, fcol.y" "MOV depr, fcol.y" = 0x00000005
- * 	      "MOV rcol.x, fcol.y" = 0x00000004
- * 0x19a8 --> as above but 0x00000100 and 0x00000000
- * 	- 0x00100000 used when KIL used
- * 0x196c --> as above but 0x00000011 and 0x00000000
- *
- * 0x1988 --> 0xXXNNNNNN
- * 	- XX == FP high something
