13684 | opcode from the mnemonic the user wrote. STR points to the | |
13685 | beginning of the mnemonic. | |
13686 | ||
13687 | This is not simply a hash table lookup, because of conditional | |
13688 | variants. Most instructions have conditional variants, which are | |
13689 | expressed with a _conditional affix_ to the mnemonic. If we were | |
13690 | to encode each conditional variant as a literal string in the opcode | |
13691 | table, it would have approximately 20,000 entries. | |
13692 | ||
13693 | Most mnemonics take this affix as a suffix, and in unified syntax, | |
13694 | 'most' is upgraded to 'all'. However, in the divided syntax, some | |
13695 | instructions take the affix as an infix, notably the s-variants of | |
13696 | the arithmetic instructions. Of those instructions, all but six | |
13697 | have the infix appear after the third character of the mnemonic. | |
13698 | ||
13699 | Accordingly, the algorithm for looking up primary opcodes given | |
13700 | an identifier is: | |
13701 | ||
13702 | 1. Look up the identifier in the opcode table. | |
13703 | If we find a match, go to step U. | |
13704 | ||
13705 | 2. Look up the last two characters of the identifier in the | |
13706 | conditions table. If we find a match, look up the first N-2 | |
13707 | characters of the identifier in the opcode table. If we | |
13708 | find a match, go to step CE. | |
13709 | ||
13710 | 3. Look up the fourth and fifth characters of the identifier in | |
13711 | the conditions table. If we find a match, extract those | |
13712 | characters from the identifier, and look up the remaining | |
13713 | characters in the opcode table. If we find a match, go | |
13714 | to step CM. | |
13715 | ||
13716 | 4. Fail. | |
13717 | ||
13718 | U. Examine the tag field of the opcode structure, in case this is | |
13719 | one of the six instructions with its conditional infix in an | |
13720 | unusual place. If it is, the tag tells us where to find the | |
13721 | infix; look it up in the conditions table and set inst.cond | |
13722 | accordingly. Otherwise, this is an unconditional instruction. | |
13723 | Again set inst.cond accordingly. Return the opcode structure. | |
13724 | ||
13725 | CE. Examine the tag field to make sure this is an instruction that | |
13726 | should receive a conditional suffix. If it is not, fail. | |
13727 | Otherwise, set inst.cond from the suffix we already looked up, | |
13728 | and return the opcode structure. | |
13729 | ||
13730 | CM. Examine the tag field to make sure this is an instruction that | |
13731 | should receive a conditional infix after the third character. | |
13732 | If it is not, fail. Otherwise, undo the edits to the current | |
13733 | line of input and proceed as for case CE. */ | |

19388 | This routine is somewhat complicated by the need for backwards |

19390 | The new options try to make the interface as compatible as | |
19391 | possible with GCC. | |
b99bd4ef | 19392 | |
c19d1205 | 19393 | New options (supported) are: |
b99bd4ef | 19394 | |
c19d1205 ZW |
19395 | -mcpu=<cpu name> Assemble for selected processor |
19396 | -march=<architecture name> Assemble for selected architecture | |
19397 | -mfpu=<fpu architecture> Assemble for selected FPU. | |
19398 | -EB/-mbig-endian Big-endian | |
19399 | -EL/-mlittle-endian Little-endian | |
19400 | -k Generate PIC code | |
19401 | -mthumb Start in Thumb mode | |
19402 | -mthumb-interwork Code supports ARM/Thumb interworking | |
b99bd4ef | 19403 | |
c19d1205 | 19404 | For now we will also provide support for: |

c19d1205 ZW |
19406 | -mapcs-32 32-bit Program counter |
19407 | -mapcs-26 26-bit Program counter | |
19408 | -macps-float Floats passed in FP registers | |
19409 | -mapcs-reentrant Reentrant code | |
19410 | -matpcs | |

19412 | and -matpcs=<list of options>) | |
b99bd4ef | 19413 | |

19414 | The remaining options are only supported for back-wards compatibility. |
19415 | Cpu variants, the arm part is optional: | |
