For reasons discussed in rems-project/isla #98 and #1557 .
Referring to the Arm adaption at https://github.com/rems-project/sail-arm/blob/master/arm-v9.4-a/src/v8_base.sail#L2256, I made changes to make registers interchangeable, thereby supporting more general symbolic execution in Isla.
However, there remains an issue: when vectorizing,
register x0needs to be included in the vector table due to grammar constraints, but it should never actually be used. BTW, theread_register_from_vectorfunction is implemented in isla.
