17647 | beginning of the mnemonic. | |
17648 | ||
17649 | This is not simply a hash table lookup, because of conditional | |
17650 | variants. Most instructions have conditional variants, which are | |
17651 | expressed with a _conditional affix_ to the mnemonic. If we were | |
17652 | to encode each conditional variant as a literal string in the opcode | |
17653 | table, it would have approximately 20,000 entries. | |
17654 | ||
17655 | Most mnemonics take this affix as a suffix, and in unified syntax, | |
17656 | 'most' is upgraded to 'all'. However, in the divided syntax, some | |
17657 | instructions take the affix as an infix, notably the s-variants of | |
17658 | the arithmetic instructions. Of those instructions, all but six | |
17659 | have the infix appear after the third character of the mnemonic. | |
17660 | ||
17661 | Accordingly, the algorithm for looking up primary opcodes given | |
17662 | an identifier is: | |
17663 | ||
17664 | 1. Look up the identifier in the opcode table. | |
17665 | If we find a match, go to step U. | |
17666 | ||
17667 | 2. Look up the last two characters of the identifier in the | |
17668 | conditions table. If we find a match, look up the first N-2 | |
17669 | characters of the identifier in the opcode table. If we | |
17670 | find a match, go to step CE. | |
17671 | ||
17672 | 3. Look up the fourth and fifth characters of the identifier in | |
17673 | the conditions table. If we find a match, extract those | |
17674 | characters from the identifier, and look up the remaining | |
17675 | characters in the opcode table. If we find a match, go | |
17676 | to step CM. | |
17677 | ||
17678 | 4. Fail. | |
17679 | ||
17680 | U. Examine the tag field of the opcode structure, in case this is | |
17681 | one of the six instructions with its conditional infix in an | |
17682 | unusual place. If it is, the tag tells us where to find the | |
17683 | infix; look it up in the conditions table and set inst.cond | |
17684 | accordingly. Otherwise, this is an unconditional instruction. | |
17685 | Again set inst.cond accordingly. Return the opcode structure. | |
17686 | ||
17687 | CE. Examine the tag field to make sure this is an instruction that | |
17688 | should receive a conditional suffix. If it is not, fail. | |
17689 | Otherwise, set inst.cond from the suffix we already looked up, | |
17690 | and return the opcode structure. | |
17691 | ||
17692 | CM. Examine the tag field to make sure this is an instruction that | |
17693 | should receive a conditional infix after the third character. | |
17694 | If it is not, fail. Otherwise, undo the edits to the current | |
17695 | line of input and proceed as for case CE. */ | |

17912 | set_it_insn_type_last () ditto | |

17914 | it_fsm_post_encode () from md_assemble () | |
17915 | force_automatic_it_block_close () from label habdling functions | |
17916 | ||
17917 | Rationale: | |
17918 | 1) md_assemble () calls it_fsm_pre_encode () before calling tencode (), | |
477330fc RM |
17919 | initializing the IT insn type with a generic initial value depending |
17920 | on the inst.condition. | |
e07e6e58 | 17921 | 2) During the tencode function, two things may happen: |
477330fc RM |
17922 | a) The tencode function overrides the IT insn type by |
17923 | calling either set_it_insn_type (type) or set_it_insn_type_last (). | |
17924 | b) The tencode function queries the IT block state by | |
17925 | calling in_it_block () (i.e. to determine narrow/not narrow mode). | |
17926 | ||
17927 | Both set_it_insn_type and in_it_block run the internal FSM state | |
17928 | handling function (handle_it_state), because: a) setting the IT insn | |
17929 | type may incur in an invalid state (exiting the function), | |
17930 | and b) querying the state requires the FSM to be updated. | |
17931 | Specifically we want to avoid creating an IT block for conditional | |
17932 | branches, so it_fsm_pre_encode is actually a guess and we can't | |
17933 | determine whether an IT block is required until the tencode () routine | |
17934 | has decided what type of instruction this actually it. | |
17935 | Because of this, if set_it_insn_type and in_it_block have to be used, | |
17936 | set_it_insn_type has to be called first. | |
17937 | ||
17938 | set_it_insn_type_last () is a wrapper of set_it_insn_type (type), that | |
17939 | determines the insn IT type depending on the inst.cond code. | |
17940 | When a tencode () routine encodes an instruction that can be | |
17941 | either outside an IT block, or, in the case of being inside, has to be | |
17942 | the last one, set_it_insn_type_last () will determine the proper | |
17943 | IT instruction type based on the inst.cond code. Otherwise, | |
17944 | set_it_insn_type can be called for overriding that logic or | |
17945 | for covering other cases. | |
17946 | ||
17947 | Calling handle_it_state () may not transition the IT block state to | |
17948 | OUTSIDE_IT_BLOCK immediatelly, since the (current) state could be | |
17949 | still queried. Instead, if the FSM determines that the state should | |
17950 | be transitioned to OUTSIDE_IT_BLOCK, a flag is marked to be closed | |
17951 | after the tencode () function: that's what it_fsm_post_encode () does. | |
17952 | ||
17953 | Since in_it_block () calls the state handling function to get an | |
17954 | updated state, an error may occur (due to invalid insns combination). | |
17955 | In that case, inst.error is set. | |
17956 | Therefore, inst.error has to be checked after the execution of | |
17957 | the tencode () routine. | |
e07e6e58 NC |
17958 | |
17959 | 3) Back in md_assemble(), it_fsm_post_encode () is called to commit | |
477330fc RM |
17960 | any pending state change (if any) that didn't take place in |
17961 | handle_it_state () as explained above. */ | |
