The following errors are reported during compilation:

As above, I'm not seeing this.

This suggests that the EX_DATA_REG() macro is going wrong somehow. Assuming the
operand types correspond to the LHS and RHS of the expression, this would mean
the GPR number is defined, but the REG value is not, and I can't currently see
how that can happen.

Now I can compile success, both versions 9.4.0 and 11.2.0.

I should have made a mistake. There is no problem using your implementation.
I will send a new version these days.

No problem; thanks for confirming!

Mark.
