Description

Writing a register index like in the example below causes an exception

    subs(REG(31), rn, imm12, shift_flag).action;

java.lang.IllegalArgumentException: Assigning 8-bit data to 5-bit location.

Right now the only way to prescribe the index is to coerce it to the properly card.

    subs(REG(coerce(card(5), 31)), rn, imm12, shift_flag).action;

It seems to require fixing.
