15008 | beginning of the mnemonic. | |
15009 | ||
15010 | This is not simply a hash table lookup, because of conditional | |
15011 | variants. Most instructions have conditional variants, which are | |
15012 | expressed with a _conditional affix_ to the mnemonic. If we were | |
15013 | to encode each conditional variant as a literal string in the opcode | |
15014 | table, it would have approximately 20,000 entries. | |
15015 | ||
15016 | Most mnemonics take this affix as a suffix, and in unified syntax, | |
15017 | 'most' is upgraded to 'all'. However, in the divided syntax, some | |
15018 | instructions take the affix as an infix, notably the s-variants of | |
15019 | the arithmetic instructions. Of those instructions, all but six | |
15020 | have the infix appear after the third character of the mnemonic. | |
15021 | ||
15022 | Accordingly, the algorithm for looking up primary opcodes given | |
15023 | an identifier is: | |
15024 | ||
15025 | 1. Look up the identifier in the opcode table. | |
15026 | If we find a match, go to step U. | |
15027 | ||
15028 | 2. Look up the last two characters of the identifier in the | |
15029 | conditions table. If we find a match, look up the first N-2 | |
15030 | characters of the identifier in the opcode table. If we | |
15031 | find a match, go to step CE. | |
15032 | ||
15033 | 3. Look up the fourth and fifth characters of the identifier in | |
15034 | the conditions table. If we find a match, extract those | |
15035 | characters from the identifier, and look up the remaining | |
15036 | characters in the opcode table. If we find a match, go | |
15037 | to step CM. | |
15038 | ||
15039 | 4. Fail. | |
15040 | ||
15041 | U. Examine the tag field of the opcode structure, in case this is | |
15042 | one of the six instructions with its conditional infix in an | |
15043 | unusual place. If it is, the tag tells us where to find the | |
15044 | infix; look it up in the conditions table and set inst.cond | |
15045 | accordingly. Otherwise, this is an unconditional instruction. | |
15046 | Again set inst.cond accordingly. Return the opcode structure. | |
15047 | ||
15048 | CE. Examine the tag field to make sure this is an instruction that | |
15049 | should receive a conditional suffix. If it is not, fail. | |
15050 | Otherwise, set inst.cond from the suffix we already looked up, | |
15051 | and return the opcode structure. | |
15052 | ||
15053 | CM. Examine the tag field to make sure this is an instruction that | |
15054 | should receive a conditional infix after the third character. | |
15055 | If it is not, fail. Otherwise, undo the edits to the current | |
15056 | line of input and proceed as for case CE. */ | |

15268 | /* The IT blocks handling machinery is accessed through the these functions: | |
15269 | it_fsm_pre_encode () from md_assemble () | |
15270 | set_it_insn_type () optional, from the tencode functions | |
15271 | set_it_insn_type_last () ditto | |
15272 | in_it_block () ditto | |
15273 | it_fsm_post_encode () from md_assemble () | |
15274 | force_automatic_it_block_close () from label habdling functions | |
15275 | ||
15276 | Rationale: | |
15277 | 1) md_assemble () calls it_fsm_pre_encode () before calling tencode (), | |
15278 | initializing the IT insn type with a generic initial value depending | |
15279 | on the inst.condition. | |
15280 | 2) During the tencode function, two things may happen: | |
15281 | a) The tencode function overrides the IT insn type by | |
15282 | calling either set_it_insn_type (type) or set_it_insn_type_last (). | |
15283 | b) The tencode function queries the IT block state by | |
15284 | calling in_it_block () (i.e. to determine narrow/not narrow mode). | |
15285 | ||
15286 | Both set_it_insn_type and in_it_block run the internal FSM state | |
15287 | handling function (handle_it_state), because: a) setting the IT insn | |
15288 | type may incur in an invalid state (exiting the function), | |
15289 | and b) querying the state requires the FSM to be updated. | |
15290 | Specifically we want to avoid creating an IT block for conditional | |
15291 | branches, so it_fsm_pre_encode is actually a guess and we can't | |
15292 | determine whether an IT block is required until the tencode () routine | |
15293 | has decided what type of instruction this actually it. | |
15294 | Because of this, if set_it_insn_type and in_it_block have to be used, | |
15295 | set_it_insn_type has to be called first. | |
15296 | ||
15297 | set_it_insn_type_last () is a wrapper of set_it_insn_type (type), that | |
15298 | determines the insn IT type depending on the inst.cond code. | |
15299 | When a tencode () routine encodes an instruction that can be | |
15300 | either outside an IT block, or, in the case of being inside, has to be | |
15301 | the last one, set_it_insn_type_last () will determine the proper | |
15302 | IT instruction type based on the inst.cond code. Otherwise, | |
15303 | set_it_insn_type can be called for overriding that logic or | |
15304 | for covering other cases. | |
15305 | ||
15306 | Calling handle_it_state () may not transition the IT block state to | |
15307 | OUTSIDE_IT_BLOCK immediatelly, since the (current) state could be | |
15308 | still queried. Instead, if the FSM determines that the state should | |
15309 | be transitioned to OUTSIDE_IT_BLOCK, a flag is marked to be closed | |
15310 | after the tencode () function: that's what it_fsm_post_encode () does. | |
15311 | ||
15312 | Since in_it_block () calls the state handling function to get an | |
15313 | updated state, an error may occur (due to invalid insns combination). | |
15314 | In that case, inst.error is set. | |
15315 | Therefore, inst.error has to be checked after the execution of | |
15316 | the tencode () routine. | |
15317 | ||
15318 | 3) Back in md_assemble(), it_fsm_post_encode () is called to commit | |
15319 | any pending state change (if any) that didn't take place in | |
15320 | handle_it_state () as explained above. */ | |
