20350 | beginning of the mnemonic. | |
20351 | ||
20352 | This is not simply a hash table lookup, because of conditional | |
20353 | variants. Most instructions have conditional variants, which are | |
20354 | expressed with a _conditional affix_ to the mnemonic. If we were | |
20355 | to encode each conditional variant as a literal string in the opcode | |
20356 | table, it would have approximately 20,000 entries. | |
20357 | ||
20358 | Most mnemonics take this affix as a suffix, and in unified syntax, | |
20359 | 'most' is upgraded to 'all'. However, in the divided syntax, some | |
20360 | instructions take the affix as an infix, notably the s-variants of | |
20361 | the arithmetic instructions. Of those instructions, all but six | |
20362 | have the infix appear after the third character of the mnemonic. | |
20363 | ||
20364 | Accordingly, the algorithm for looking up primary opcodes given | |
20365 | an identifier is: | |
20366 | ||
20367 | 1. Look up the identifier in the opcode table. | |
20368 | If we find a match, go to step U. | |
20369 | ||
20370 | 2. Look up the last two characters of the identifier in the | |
20371 | conditions table. If we find a match, look up the first N-2 | |
20372 | characters of the identifier in the opcode table. If we | |
20373 | find a match, go to step CE. | |
20374 | ||
20375 | 3. Look up the fourth and fifth characters of the identifier in | |
20376 | the conditions table. If we find a match, extract those | |
20377 | characters from the identifier, and look up the remaining | |
20378 | characters in the opcode table. If we find a match, go | |
20379 | to step CM. | |
20380 | ||
20381 | 4. Fail. | |
20382 | ||
20383 | U. Examine the tag field of the opcode structure, in case this is | |
20384 | one of the six instructions with its conditional infix in an | |
20385 | unusual place. If it is, the tag tells us where to find the | |
20386 | infix; look it up in the conditions table and set inst.cond | |
20387 | accordingly. Otherwise, this is an unconditional instruction. | |
20388 | Again set inst.cond accordingly. Return the opcode structure. | |
20389 | ||
20390 | CE. Examine the tag field to make sure this is an instruction that | |
20391 | should receive a conditional suffix. If it is not, fail. | |
20392 | Otherwise, set inst.cond from the suffix we already looked up, | |
20393 | and return the opcode structure. | |
20394 | ||
20395 | CM. Examine the tag field to make sure this is an instruction that | |
20396 | should receive a conditional infix after the third character. | |
20397 | If it is not, fail. Otherwise, undo the edits to the current | |
20398 | line of input and proceed as for case CE. */ | |

e07e6e58 NC |
20637 | |
20638 | Rationale: | |
20639 | 1) md_assemble () calls it_fsm_pre_encode () before calling tencode (), | |
477330fc RM |
20640 | initializing the IT insn type with a generic initial value depending |
20641 | on the inst.condition. | |
e07e6e58 | 20642 | 2) During the tencode function, two things may happen: |
477330fc | 20643 | a) The tencode function overrides the IT insn type by |
5ee91343 AV |
20644 | calling either set_pred_insn_type (type) or |
20645 | set_pred_insn_type_last (). | |
477330fc | 20646 | b) The tencode function queries the IT block state by |
5ee91343 | 20647 | calling in_pred_block () (i.e. to determine narrow/not narrow mode). |
477330fc | 20648 | |
5ee91343 AV |
20649 | Both set_pred_insn_type and in_pred_block run the internal FSM state |
20650 | handling function (handle_pred_state), because: a) setting the IT insn | |
477330fc RM |
20651 | type may incur in an invalid state (exiting the function), |
20652 | and b) querying the state requires the FSM to be updated. | |
20653 | Specifically we want to avoid creating an IT block for conditional | |
20654 | branches, so it_fsm_pre_encode is actually a guess and we can't | |
20655 | determine whether an IT block is required until the tencode () routine | |
20656 | has decided what type of instruction this actually it. | |
5ee91343 AV |
20657 | Because of this, if set_pred_insn_type and in_pred_block have to be |
20658 | used, set_pred_insn_type has to be called first. | |
477330fc | 20659 | |
5ee91343 AV |
20660 | set_pred_insn_type_last () is a wrapper of set_pred_insn_type (type), |
20661 | that determines the insn IT type depending on the inst.cond code. | |
477330fc RM |
20662 | When a tencode () routine encodes an instruction that can be |
20663 | either outside an IT block, or, in the case of being inside, has to be | |
5ee91343 | 20664 | the last one, set_pred_insn_type_last () will determine the proper |
477330fc | 20665 | IT instruction type based on the inst.cond code. Otherwise, |
5ee91343 | 20666 | set_pred_insn_type can be called for overriding that logic or |
477330fc RM |
20667 | for covering other cases. |
20668 | ||
5ee91343 AV |
20669 | Calling handle_pred_state () may not transition the IT block state to |
20670 | OUTSIDE_PRED_BLOCK immediately, since the (current) state could be | |
477330fc | 20671 | still queried. Instead, if the FSM determines that the state should |
5ee91343 | 20672 | be transitioned to OUTSIDE_PRED_BLOCK, a flag is marked to be closed |
477330fc RM |
20673 | after the tencode () function: that's what it_fsm_post_encode () does. |
20674 | ||
5ee91343 | 20675 | Since in_pred_block () calls the state handling function to get an |
477330fc RM |
20676 | updated state, an error may occur (due to invalid insns combination). |
20677 | In that case, inst.error is set. | |
20678 | Therefore, inst.error has to be checked after the execution of | |
20679 | the tencode () routine. | |
e07e6e58 NC |
20680 | |
20681 | 3) Back in md_assemble(), it_fsm_post_encode () is called to commit | |
477330fc | 20682 | any pending state change (if any) that didn't take place in |
5ee91343 | 20683 | handle_pred_state () as explained above. */ |
