// FIXME: We need a way to check whether a prefix supports predication,
// otherwise we will end up with an ambiguity for instructions that happen to
// end with a predicate name.
+ // FIXME: Likewise, some arithmetic instructions have an 's' prefix which
+ // indicates to update the condition codes. Those instructions have an
+ // additional immediate operand which encodes the prefix as reg0 or CPSR.
+ // Just checking for a suffix of 's' definitely creates ambiguities; e.g,
+ // the SMMLS instruction.
