18032 | beginning of the mnemonic. | |
18033 | ||
18034 | This is not simply a hash table lookup, because of conditional | |
18035 | variants. Most instructions have conditional variants, which are | |
18036 | expressed with a _conditional affix_ to the mnemonic. If we were | |
18037 | to encode each conditional variant as a literal string in the opcode | |
18038 | table, it would have approximately 20,000 entries. | |
18039 | ||
18040 | Most mnemonics take this affix as a suffix, and in unified syntax, | |
18041 | 'most' is upgraded to 'all'. However, in the divided syntax, some | |
18042 | instructions take the affix as an infix, notably the s-variants of | |
18043 | the arithmetic instructions. Of those instructions, all but six | |
18044 | have the infix appear after the third character of the mnemonic. | |
18045 | ||
18046 | Accordingly, the algorithm for looking up primary opcodes given | |
18047 | an identifier is: | |
18048 | ||
18049 | 1. Look up the identifier in the opcode table. | |
18050 | If we find a match, go to step U. | |
18051 | ||
18052 | 2. Look up the last two characters of the identifier in the | |
18053 | conditions table. If we find a match, look up the first N-2 | |
18054 | characters of the identifier in the opcode table. If we | |
18055 | find a match, go to step CE. | |
18056 | ||
18057 | 3. Look up the fourth and fifth characters of the identifier in | |
18058 | the conditions table. If we find a match, extract those | |
18059 | characters from the identifier, and look up the remaining | |
18060 | characters in the opcode table. If we find a match, go | |
18061 | to step CM. | |
18062 | ||
18063 | 4. Fail. | |
18064 | ||
18065 | U. Examine the tag field of the opcode structure, in case this is | |
18066 | one of the six instructions with its conditional infix in an | |
18067 | unusual place. If it is, the tag tells us where to find the | |
18068 | infix; look it up in the conditions table and set inst.cond | |
18069 | accordingly. Otherwise, this is an unconditional instruction. | |
18070 | Again set inst.cond accordingly. Return the opcode structure. | |
18071 | ||
18072 | CE. Examine the tag field to make sure this is an instruction that | |
18073 | should receive a conditional suffix. If it is not, fail. | |
18074 | Otherwise, set inst.cond from the suffix we already looked up, | |
18075 | and return the opcode structure. | |
18076 | ||
18077 | CM. Examine the tag field to make sure this is an instruction that | |
18078 | should receive a conditional infix after the third character. | |
18079 | If it is not, fail. Otherwise, undo the edits to the current | |
18080 | line of input and proceed as for case CE. */ | |

33eaf5de | 18300 | force_automatic_it_block_close () from label handling functions |
e07e6e58 NC |
18301 | |
18302 | Rationale: | |
18303 | 1) md_assemble () calls it_fsm_pre_encode () before calling tencode (), | |
477330fc RM |
18304 | initializing the IT insn type with a generic initial value depending |
18305 | on the inst.condition. | |
e07e6e58 | 18306 | 2) During the tencode function, two things may happen: |
477330fc RM |
18307 | a) The tencode function overrides the IT insn type by |
18308 | calling either set_it_insn_type (type) or set_it_insn_type_last (). | |
18309 | b) The tencode function queries the IT block state by | |
18310 | calling in_it_block () (i.e. to determine narrow/not narrow mode). | |
18311 | ||
18312 | Both set_it_insn_type and in_it_block run the internal FSM state | |
18313 | handling function (handle_it_state), because: a) setting the IT insn | |
18314 | type may incur in an invalid state (exiting the function), | |
18315 | and b) querying the state requires the FSM to be updated. | |
18316 | Specifically we want to avoid creating an IT block for conditional | |
18317 | branches, so it_fsm_pre_encode is actually a guess and we can't | |
18318 | determine whether an IT block is required until the tencode () routine | |
18319 | has decided what type of instruction this actually it. | |
18320 | Because of this, if set_it_insn_type and in_it_block have to be used, | |
18321 | set_it_insn_type has to be called first. | |
18322 | ||
18323 | set_it_insn_type_last () is a wrapper of set_it_insn_type (type), that | |
18324 | determines the insn IT type depending on the inst.cond code. | |
18325 | When a tencode () routine encodes an instruction that can be | |
18326 | either outside an IT block, or, in the case of being inside, has to be | |
18327 | the last one, set_it_insn_type_last () will determine the proper | |
18328 | IT instruction type based on the inst.cond code. Otherwise, | |
18329 | set_it_insn_type can be called for overriding that logic or | |
18330 | for covering other cases. | |
18331 | ||
18332 | Calling handle_it_state () may not transition the IT block state to | |
2b0f3761 | 18333 | OUTSIDE_IT_BLOCK immediately, since the (current) state could be |
477330fc RM |
18334 | still queried. Instead, if the FSM determines that the state should |
18335 | be transitioned to OUTSIDE_IT_BLOCK, a flag is marked to be closed | |
18336 | after the tencode () function: that's what it_fsm_post_encode () does. | |
18337 | ||
18338 | Since in_it_block () calls the state handling function to get an | |
18339 | updated state, an error may occur (due to invalid insns combination). | |
18340 | In that case, inst.error is set. | |
18341 | Therefore, inst.error has to be checked after the execution of | |
18342 | the tencode () routine. | |
e07e6e58 NC |
18343 | |
18344 | 3) Back in md_assemble(), it_fsm_post_encode () is called to commit | |
477330fc RM |
18345 | any pending state change (if any) that didn't take place in |
18346 | handle_it_state () as explained above. */ | |

25498 | This routine is somewhat complicated by the need for backwards |
25499 | compatibility (since older releases of gcc can't be changed). | |
25500 | The new options try to make the interface as compatible as | |
25501 | possible with GCC. | |
b99bd4ef | 25502 | |
c19d1205 | 25503 | New options (supported) are: |
b99bd4ef | 25504 | |
c19d1205 ZW |
25505 | -mcpu=<cpu name> Assemble for selected processor |
25506 | -march=<architecture name> Assemble for selected architecture | |
25507 | -mfpu=<fpu architecture> Assemble for selected FPU. | |
25508 | -EB/-mbig-endian Big-endian | |
25509 | -EL/-mlittle-endian Little-endian | |
25510 | -k Generate PIC code | |
25511 | -mthumb Start in Thumb mode | |
25512 | -mthumb-interwork Code supports ARM/Thumb interworking | |
b99bd4ef | 25513 | |

267bf995 | 25516 | |
c19d1205 | 25517 | For now we will also provide support for: |
b99bd4ef | 25518 | |
c19d1205 ZW |
25519 | -mapcs-32 32-bit Program counter |
25520 | -mapcs-26 26-bit Program counter | |
25521 | -macps-float Floats passed in FP registers | |
25522 | -mapcs-reentrant Reentrant code | |
25523 | -matpcs | |
25524 | (sometime these will probably be replaced with -mapcs=<list of options> | |
25525 | and -matpcs=<list of options>) | |
b99bd4ef | 25526 | |
c19d1205 ZW |
25527 | The remaining options are only supported for back-wards compatibility. |
25528 | Cpu variants, the arm part is optional: | |
