Rationale:
1) md_assemble () calls it_fsm_pre_encode () before calling tencode (),
- initializing the IT insn type with a generic initial value depending
- on the inst.condition.
+ initializing the IT insn type with a generic initial value depending
+ on the inst.condition.
2) During the tencode function, two things may happen:
- a) The tencode function overrides the IT insn type by
- calling either set_it_insn_type (type) or set_it_insn_type_last ().
- b) The tencode function queries the IT block state by
- calling in_it_block () (i.e. to determine narrow/not narrow mode).
-
- Both set_it_insn_type and in_it_block run the internal FSM state
- handling function (handle_it_state), because: a) setting the IT insn
- type may incur in an invalid state (exiting the function),
- and b) querying the state requires the FSM to be updated.
- Specifically we want to avoid creating an IT block for conditional
- branches, so it_fsm_pre_encode is actually a guess and we can't
- determine whether an IT block is required until the tencode () routine
- has decided what type of instruction this actually it.
- Because of this, if set_it_insn_type and in_it_block have to be used,
- set_it_insn_type has to be called first.
-
- set_it_insn_type_last () is a wrapper of set_it_insn_type (type), that
- determines the insn IT type depending on the inst.cond code.
- When a tencode () routine encodes an instruction that can be
- either outside an IT block, or, in the case of being inside, has to be
- the last one, set_it_insn_type_last () will determine the proper
- IT instruction type based on the inst.cond code. Otherwise,
- set_it_insn_type can be called for overriding that logic or
- for covering other cases.
-
- Calling handle_it_state () may not transition the IT block state to
- OUTSIDE_IT_BLOCK immediatelly, since the (current) state could be
- still queried. Instead, if the FSM determines that the state should
- be transitioned to OUTSIDE_IT_BLOCK, a flag is marked to be closed
- after the tencode () function: that's what it_fsm_post_encode () does.
-
- Since in_it_block () calls the state handling function to get an
- updated state, an error may occur (due to invalid insns combination).
- In that case, inst.error is set.
- Therefore, inst.error has to be checked after the execution of
- the tencode () routine.
