20126 | beginning of the mnemonic. | |
20127 | ||
20128 | This is not simply a hash table lookup, because of conditional | |
20129 | variants. Most instructions have conditional variants, which are | |
20130 | expressed with a _conditional affix_ to the mnemonic. If we were | |
20131 | to encode each conditional variant as a literal string in the opcode | |
20132 | table, it would have approximately 20,000 entries. | |
20133 | ||
20134 | Most mnemonics take this affix as a suffix, and in unified syntax, | |
20135 | 'most' is upgraded to 'all'. However, in the divided syntax, some | |
20136 | instructions take the affix as an infix, notably the s-variants of | |
20137 | the arithmetic instructions. Of those instructions, all but six | |
20138 | have the infix appear after the third character of the mnemonic. | |
20139 | ||
20140 | Accordingly, the algorithm for looking up primary opcodes given | |
20141 | an identifier is: | |
20142 | ||
20143 | 1. Look up the identifier in the opcode table. | |
20144 | If we find a match, go to step U. | |
20145 | ||
20146 | 2. Look up the last two characters of the identifier in the | |
20147 | conditions table. If we find a match, look up the first N-2 | |
20148 | characters of the identifier in the opcode table. If we | |
20149 | find a match, go to step CE. | |
20150 | ||
20151 | 3. Look up the fourth and fifth characters of the identifier in | |
20152 | the conditions table. If we find a match, extract those | |
20153 | characters from the identifier, and look up the remaining | |
20154 | characters in the opcode table. If we find a match, go | |
20155 | to step CM. | |
20156 | ||
20157 | 4. Fail. | |
20158 | ||
20159 | U. Examine the tag field of the opcode structure, in case this is | |
20160 | one of the six instructions with its conditional infix in an | |
20161 | unusual place. If it is, the tag tells us where to find the | |
20162 | infix; look it up in the conditions table and set inst.cond | |
20163 | accordingly. Otherwise, this is an unconditional instruction. | |
20164 | Again set inst.cond accordingly. Return the opcode structure. | |
20165 | ||
20166 | CE. Examine the tag field to make sure this is an instruction that | |
20167 | should receive a conditional suffix. If it is not, fail. | |
20168 | Otherwise, set inst.cond from the suffix we already looked up, | |
20169 | and return the opcode structure. | |
20170 | ||
20171 | CM. Examine the tag field to make sure this is an instruction that | |
20172 | should receive a conditional infix after the third character. | |
20173 | If it is not, fail. Otherwise, undo the edits to the current | |
20174 | line of input and proceed as for case CE. */ | |

33eaf5de | 20412 | force_automatic_it_block_close () from label handling functions |
e07e6e58 NC |
20413 | |
20414 | Rationale: | |
20415 | 1) md_assemble () calls it_fsm_pre_encode () before calling tencode (), | |
477330fc RM |
20416 | initializing the IT insn type with a generic initial value depending |
20417 | on the inst.condition. | |
e07e6e58 | 20418 | 2) During the tencode function, two things may happen: |
477330fc | 20419 | a) The tencode function overrides the IT insn type by |
5ee91343 AV |
20420 | calling either set_pred_insn_type (type) or |
20421 | set_pred_insn_type_last (). | |
477330fc | 20422 | b) The tencode function queries the IT block state by |
5ee91343 | 20423 | calling in_pred_block () (i.e. to determine narrow/not narrow mode). |
477330fc | 20424 | |
5ee91343 AV |
20425 | Both set_pred_insn_type and in_pred_block run the internal FSM state |
20426 | handling function (handle_pred_state), because: a) setting the IT insn | |
477330fc RM |
20427 | type may incur in an invalid state (exiting the function), |
20428 | and b) querying the state requires the FSM to be updated. | |
20429 | Specifically we want to avoid creating an IT block for conditional | |
20430 | branches, so it_fsm_pre_encode is actually a guess and we can't | |
20431 | determine whether an IT block is required until the tencode () routine | |
20432 | has decided what type of instruction this actually it. | |
5ee91343 AV |
20433 | Because of this, if set_pred_insn_type and in_pred_block have to be |
20434 | used, set_pred_insn_type has to be called first. | |
477330fc | 20435 | |
5ee91343 AV |
20436 | set_pred_insn_type_last () is a wrapper of set_pred_insn_type (type), |
20437 | that determines the insn IT type depending on the inst.cond code. | |
477330fc RM |
20438 | When a tencode () routine encodes an instruction that can be |
20439 | either outside an IT block, or, in the case of being inside, has to be | |
5ee91343 | 20440 | the last one, set_pred_insn_type_last () will determine the proper |
477330fc | 20441 | IT instruction type based on the inst.cond code. Otherwise, |
5ee91343 | 20442 | set_pred_insn_type can be called for overriding that logic or |
477330fc RM |
20443 | for covering other cases. |
20444 | ||
5ee91343 AV |
20445 | Calling handle_pred_state () may not transition the IT block state to |
20446 | OUTSIDE_PRED_BLOCK immediately, since the (current) state could be | |
477330fc | 20447 | still queried. Instead, if the FSM determines that the state should |
5ee91343 | 20448 | be transitioned to OUTSIDE_PRED_BLOCK, a flag is marked to be closed |
477330fc RM |
20449 | after the tencode () function: that's what it_fsm_post_encode () does. |
20450 | ||
5ee91343 | 20451 | Since in_pred_block () calls the state handling function to get an |
477330fc RM |
20452 | updated state, an error may occur (due to invalid insns combination). |
20453 | In that case, inst.error is set. | |
20454 | Therefore, inst.error has to be checked after the execution of | |
20455 | the tencode () routine. | |
e07e6e58 NC |
20456 | |
20457 | 3) Back in md_assemble(), it_fsm_post_encode () is called to commit | |
477330fc | 20458 | any pending state change (if any) that didn't take place in |
5ee91343 | 20459 | handle_pred_state () as explained above. */ |
