you should not use bz_v like this. Instead you should create BranchSimd macro
the same way there is Branch macro and BranchF macro. Having in mind that delay
slots are slowly going away, this will make things easier to maintain in the
future.

Done.

This surprised me before I remembered the MIPS delay slot.

[dusan.simicic, 2017/04/06 10:50:11]

Yes, first li() is in branch delay slot. I'll add a comment to make this a
little bit clear. Also, this works only if li() macro generates only one
instruction (imm const is small enough for 16bit offset's field).
