16523 | beginning of the mnemonic. | |
16524 | ||
16525 | This is not simply a hash table lookup, because of conditional | |
16526 | variants. Most instructions have conditional variants, which are | |
16527 | expressed with a _conditional affix_ to the mnemonic. If we were | |
16528 | to encode each conditional variant as a literal string in the opcode | |
16529 | table, it would have approximately 20,000 entries. | |
16530 | ||
16531 | Most mnemonics take this affix as a suffix, and in unified syntax, | |
16532 | 'most' is upgraded to 'all'. However, in the divided syntax, some | |
16533 | instructions take the affix as an infix, notably the s-variants of | |
16534 | the arithmetic instructions. Of those instructions, all but six | |
16535 | have the infix appear after the third character of the mnemonic. | |
16536 | ||
16537 | Accordingly, the algorithm for looking up primary opcodes given | |
16538 | an identifier is: | |
16539 | ||
16540 | 1. Look up the identifier in the opcode table. | |
16541 | If we find a match, go to step U. | |
16542 | ||
16543 | 2. Look up the last two characters of the identifier in the | |
16544 | conditions table. If we find a match, look up the first N-2 | |
16545 | characters of the identifier in the opcode table. If we | |
16546 | find a match, go to step CE. | |
16547 | ||
16548 | 3. Look up the fourth and fifth characters of the identifier in | |
16549 | the conditions table. If we find a match, extract those | |
16550 | characters from the identifier, and look up the remaining | |
16551 | characters in the opcode table. If we find a match, go | |
16552 | to step CM. | |
16553 | ||
16554 | 4. Fail. | |
16555 | ||
16556 | U. Examine the tag field of the opcode structure, in case this is | |
16557 | one of the six instructions with its conditional infix in an | |
16558 | unusual place. If it is, the tag tells us where to find the | |
16559 | infix; look it up in the conditions table and set inst.cond | |
16560 | accordingly. Otherwise, this is an unconditional instruction. | |
16561 | Again set inst.cond accordingly. Return the opcode structure. | |
16562 | ||
16563 | CE. Examine the tag field to make sure this is an instruction that | |
16564 | should receive a conditional suffix. If it is not, fail. | |
16565 | Otherwise, set inst.cond from the suffix we already looked up, | |
16566 | and return the opcode structure. | |
16567 | ||
16568 | CM. Examine the tag field to make sure this is an instruction that | |
16569 | should receive a conditional infix after the third character. | |
16570 | If it is not, fail. Otherwise, undo the edits to the current | |
16571 | line of input and proceed as for case CE. */ | |

16788 | set_it_insn_type_last () ditto | |

16790 | it_fsm_post_encode () from md_assemble () | |
16791 | force_automatic_it_block_close () from label habdling functions | |
16792 | ||
16793 | Rationale: | |
16794 | 1) md_assemble () calls it_fsm_pre_encode () before calling tencode (), | |
16795 | initializing the IT insn type with a generic initial value depending | |
16796 | on the inst.condition. | |
16797 | 2) During the tencode function, two things may happen: | |
16798 | a) The tencode function overrides the IT insn type by | |
16799 | calling either set_it_insn_type (type) or set_it_insn_type_last (). | |
16800 | b) The tencode function queries the IT block state by | |
16801 | calling in_it_block () (i.e. to determine narrow/not narrow mode). | |
16802 | ||
16803 | Both set_it_insn_type and in_it_block run the internal FSM state | |
16804 | handling function (handle_it_state), because: a) setting the IT insn | |
16805 | type may incur in an invalid state (exiting the function), | |
16806 | and b) querying the state requires the FSM to be updated. | |
16807 | Specifically we want to avoid creating an IT block for conditional | |
16808 | branches, so it_fsm_pre_encode is actually a guess and we can't | |
16809 | determine whether an IT block is required until the tencode () routine | |
16810 | has decided what type of instruction this actually it. | |
16811 | Because of this, if set_it_insn_type and in_it_block have to be used, | |
16812 | set_it_insn_type has to be called first. | |
16813 | ||
16814 | set_it_insn_type_last () is a wrapper of set_it_insn_type (type), that | |
16815 | determines the insn IT type depending on the inst.cond code. | |
16816 | When a tencode () routine encodes an instruction that can be | |
16817 | either outside an IT block, or, in the case of being inside, has to be | |
16818 | the last one, set_it_insn_type_last () will determine the proper | |
16819 | IT instruction type based on the inst.cond code. Otherwise, | |
16820 | set_it_insn_type can be called for overriding that logic or | |
16821 | for covering other cases. | |
16822 | ||
16823 | Calling handle_it_state () may not transition the IT block state to | |
16824 | OUTSIDE_IT_BLOCK immediatelly, since the (current) state could be | |
16825 | still queried. Instead, if the FSM determines that the state should | |
16826 | be transitioned to OUTSIDE_IT_BLOCK, a flag is marked to be closed | |
16827 | after the tencode () function: that's what it_fsm_post_encode () does. | |
16828 | ||
16829 | Since in_it_block () calls the state handling function to get an | |
16830 | updated state, an error may occur (due to invalid insns combination). | |
16831 | In that case, inst.error is set. | |
16832 | Therefore, inst.error has to be checked after the execution of | |
16833 | the tencode () routine. | |
16834 | ||
16835 | 3) Back in md_assemble(), it_fsm_post_encode () is called to commit | |
16836 | any pending state change (if any) that didn't take place in | |
16837 | handle_it_state () as explained above. */ | |
