IIRC, Linux ABI does not follow the ARM AAPCS that uses variable-width enumeration. On Linux, enumerated values are stored as a native integer value, whatever the enumerated values. With AAPCS/ATPCS, if the enumerated values can be stored as a byte, a byte is used: --with-abi=aapcs I don't know if the issue is related to this ABI discrepancy. > Also, it's not a jump table but a lookup table.
