+/* ARL - gallium craps itself on progs/vp/arl.txt
+ *
+ * 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
