15621 /* Subroutine of md_assemble, responsible for looking up the primary
15622 opcode from the mnemonic the user wrote. STR points to the
15623 beginning of the mnemonic.
15625 This is not simply a hash table lookup, because of conditional
15626 variants. Most instructions have conditional variants, which are
15627 expressed with a _conditional affix_ to the mnemonic. If we were
15628 to encode each conditional variant as a literal string in the opcode
15629 table, it would have approximately 20,000 entries.
15631 Most mnemonics take this affix as a suffix, and in unified syntax,
15632 'most' is upgraded to 'all'. However, in the divided syntax, some
15633 instructions take the affix as an infix, notably the s-variants of
15634 the arithmetic instructions. Of those instructions, all but six
15635 have the infix appear after the third character of the mnemonic.
15637 Accordingly, the algorithm for looking up primary opcodes given
15640 1. Look up the identifier in the opcode table.
15641 If we find a match, go to step U.
15643 2. Look up the last two characters of the identifier in the
15644 conditions table. If we find a match, look up the first N-2
15645 characters of the identifier in the opcode table. If we
15646 find a match, go to step CE.
15648 3. Look up the fourth and fifth characters of the identifier in
15649 the conditions table. If we find a match, extract those
15650 characters from the identifier, and look up the remaining
15651 characters in the opcode table. If we find a match, go
15656 U. Examine the tag field of the opcode structure, in case this is
15657 one of the six instructions with its conditional infix in an
15658 unusual place. If it is, the tag tells us where to find the
15659 infix; look it up in the conditions table and set inst.cond
15660 accordingly. Otherwise, this is an unconditional instruction.
15661 Again set inst.cond accordingly. Return the opcode structure.
15663 CE. Examine the tag field to make sure this is an instruction that
15664 should receive a conditional suffix. If it is not, fail.
15665 Otherwise, set inst.cond from the suffix we already looked up,
15666 and return the opcode structure.
15668 CM. Examine the tag field to make sure this is an instruction that
15669 should receive a conditional infix after the third character.
15670 If it is not, fail. Otherwise, undo the edits to the current
15671 line of input and proceed as for case CE. */

15888 it_fsm_post_encode () from md_assemble ()
15889 force_automatic_it_block_close () from label habdling functions
15892 1) md_assemble () calls it_fsm_pre_encode () before calling tencode (),
15893 initializing the IT insn type with a generic initial value depending
15894 on the inst.condition.
15895 2) During the tencode function, two things may happen:
15896 a) The tencode function overrides the IT insn type by
15897 calling either set_it_insn_type (type) or set_it_insn_type_last ().
15898 b) The tencode function queries the IT block state by
15899 calling in_it_block () (i.e. to determine narrow/not narrow mode).
15901 Both set_it_insn_type and in_it_block run the internal FSM state
15902 handling function (handle_it_state), because: a) setting the IT insn
15903 type may incur in an invalid state (exiting the function),
15904 and b) querying the state requires the FSM to be updated.
15905 Specifically we want to avoid creating an IT block for conditional
15906 branches, so it_fsm_pre_encode is actually a guess and we can't
15907 determine whether an IT block is required until the tencode () routine
15908 has decided what type of instruction this actually it.
15909 Because of this, if set_it_insn_type and in_it_block have to be used,
15910 set_it_insn_type has to be called first.
15912 set_it_insn_type_last () is a wrapper of set_it_insn_type (type), that
15913 determines the insn IT type depending on the inst.cond code.
15914 When a tencode () routine encodes an instruction that can be
15915 either outside an IT block, or, in the case of being inside, has to be
15916 the last one, set_it_insn_type_last () will determine the proper
15917 IT instruction type based on the inst.cond code. Otherwise,
15918 set_it_insn_type can be called for overriding that logic or
15919 for covering other cases.
15921 Calling handle_it_state () may not transition the IT block state to
15922 OUTSIDE_IT_BLOCK immediatelly, since the (current) state could be
15923 still queried. Instead, if the FSM determines that the state should
15924 be transitioned to OUTSIDE_IT_BLOCK, a flag is marked to be closed
15925 after the tencode () function: that's what it_fsm_post_encode () does.
15927 Since in_it_block () calls the state handling function to get an
15928 updated state, an error may occur (due to invalid insns combination).
15929 In that case, inst.error is set.
15930 Therefore, inst.error has to be checked after the execution of
15931 the tencode () routine.
15933 3) Back in md_assemble(), it_fsm_post_encode () is called to commit
15934 any pending state change (if any) that didn't take place in
15935 handle_it_state () as explained above. */

22433 Invocation line includes a switch not recognized by the base assembler.
22434 See if it's a processor-specific option.
22436 This routine is somewhat complicated by the need for backwards
22437 compatibility (since older releases of gcc can't be changed).
22438 The new options try to make the interface as compatible as
22441 New options (supported) are:
22443 -mcpu=<cpu name> Assemble for selected processor
22444 -march=<architecture name> Assemble for selected architecture
22445 -mfpu=<fpu architecture> Assemble for selected FPU.
22446 -EB/-mbig-endian Big-endian
22447 -EL/-mlittle-endian Little-endian
22448 -k Generate PIC code
22449 -mthumb Start in Thumb mode
22450 -mthumb-interwork Code supports ARM/Thumb interworking
22452 -m[no-]warn-deprecated Warn about deprecated features
22454 For now we will also provide support for:
22456 -mapcs-32 32-bit Program counter
22457 -mapcs-26 26-bit Program counter
22458 -macps-float Floats passed in FP registers
22459 -mapcs-reentrant Reentrant code
22461 (sometime these will probably be replaced with -mapcs=<list of options>
22462 and -matpcs=<list of options>)
22464 The remaining options are only supported for back-wards compatibility.
22465 Cpu variants, the arm part is optional:
22466 -m[arm]1 Currently not supported.
22467 -m[arm]2, -m[arm]250 Arm 2 and Arm 250 processor
22468 -m[arm]3 Arm 3 processor
22469 -m[arm]6[xx], Arm 6 processors
22470 -m[arm]7[xx][t][[d]m] Arm 7 processors
22471 -m[arm]8[10] Arm 8 processors
22472 -m[arm]9[20][tdmi] Arm 9 processors
22473 -mstrongarm[110[0]] StrongARM processors
22474 -mxscale XScale processors
22475 -m[arm]v[2345[t[e]]] Arm architectures
22476 -mall All (except the ARM1)
22478 -mfpa10, -mfpa11 FPA10 and 11 co-processor instructions
22479 -mfpe-old (No float load/store multiples)
22480 -mvfpxd VFP Single precision
22482 -mno-fpu Disable all floating point instructions
