Thanks - I see part of the confusion was my fault as there isn't an existing test for bl, only for b and blr. The new test looks OK, although I would move it into the `Unconditional branch (immediate)` section (a label is just an immediate, after all).

For the new crc instructions added - did you intent to test the forwarding of crcs into one another? If not it might be better to make sure there is test coverage in V1-basic-instructions.s instead. Either way they are not the biggest deal and this looks good to me otherwise.
