Space would be the problem here, although I'd love to have the capability.

We've got a lot of conditional tests against X or complex XY. There fourteen tests against 0 and 1, six tests for complex 0, complex 1 and complex i. Two tests for signed zero, seven tests of X against a register and two for complex X against a register pair.

Multiply these by the number of registers for whichs tests should be available (Y, Z, T, L, A, B, C, D, I, J, K, ZT, AB, CD, IL, JK) and then allocate a command table entry for each. Several kilobytes minimum I suspect. The actual code to implement the tests would be relatively small if done properly.
