15010 /* Subroutine of md_assemble, responsible for looking up the primary
15011 opcode from the mnemonic the user wrote. STR points to the
15012 beginning of the mnemonic.
15014 This is not simply a hash table lookup, because of conditional
15015 variants. Most instructions have conditional variants, which are
15016 expressed with a _conditional affix_ to the mnemonic. If we were
15017 to encode each conditional variant as a literal string in the opcode
15018 table, it would have approximately 20,000 entries.
15020 Most mnemonics take this affix as a suffix, and in unified syntax,
15021 'most' is upgraded to 'all'. However, in the divided syntax, some
15022 instructions take the affix as an infix, notably the s-variants of
15023 the arithmetic instructions. Of those instructions, all but six
15024 have the infix appear after the third character of the mnemonic.
15026 Accordingly, the algorithm for looking up primary opcodes given
15029 1. Look up the identifier in the opcode table.
15030 If we find a match, go to step U.
15032 2. Look up the last two characters of the identifier in the
15033 conditions table. If we find a match, look up the first N-2
15034 characters of the identifier in the opcode table. If we
15035 find a match, go to step CE.
15037 3. Look up the fourth and fifth characters of the identifier in
15038 the conditions table. If we find a match, extract those
15039 characters from the identifier, and look up the remaining
15040 characters in the opcode table. If we find a match, go
15045 U. Examine the tag field of the opcode structure, in case this is
15046 one of the six instructions with its conditional infix in an
15047 unusual place. If it is, the tag tells us where to find the
15048 infix; look it up in the conditions table and set inst.cond
15049 accordingly. Otherwise, this is an unconditional instruction.
15050 Again set inst.cond accordingly. Return the opcode structure.
15052 CE. Examine the tag field to make sure this is an instruction that
15053 should receive a conditional suffix. If it is not, fail.
15054 Otherwise, set inst.cond from the suffix we already looked up,
15055 and return the opcode structure.
15057 CM. Examine the tag field to make sure this is an instruction that
15058 should receive a conditional infix after the third character.
15059 If it is not, fail. Otherwise, undo the edits to the current
15060 line of input and proceed as for case CE. */

15277 it_fsm_post_encode () from md_assemble ()
15278 force_automatic_it_block_close () from label habdling functions
15281 1) md_assemble () calls it_fsm_pre_encode () before calling tencode (),
15282 initializing the IT insn type with a generic initial value depending
15283 on the inst.condition.
15284 2) During the tencode function, two things may happen:
15285 a) The tencode function overrides the IT insn type by
15286 calling either set_it_insn_type (type) or set_it_insn_type_last ().
15287 b) The tencode function queries the IT block state by
15288 calling in_it_block () (i.e. to determine narrow/not narrow mode).
15290 Both set_it_insn_type and in_it_block run the internal FSM state
15291 handling function (handle_it_state), because: a) setting the IT insn
15292 type may incur in an invalid state (exiting the function),
15293 and b) querying the state requires the FSM to be updated.
15294 Specifically we want to avoid creating an IT block for conditional
15295 branches, so it_fsm_pre_encode is actually a guess and we can't
15296 determine whether an IT block is required until the tencode () routine
15297 has decided what type of instruction this actually it.
15298 Because of this, if set_it_insn_type and in_it_block have to be used,
15299 set_it_insn_type has to be called first.
15301 set_it_insn_type_last () is a wrapper of set_it_insn_type (type), that
15302 determines the insn IT type depending on the inst.cond code.
15303 When a tencode () routine encodes an instruction that can be
15304 either outside an IT block, or, in the case of being inside, has to be
15305 the last one, set_it_insn_type_last () will determine the proper
15306 IT instruction type based on the inst.cond code. Otherwise,
15307 set_it_insn_type can be called for overriding that logic or
15308 for covering other cases.
15310 Calling handle_it_state () may not transition the IT block state to
15311 OUTSIDE_IT_BLOCK immediatelly, since the (current) state could be
15312 still queried. Instead, if the FSM determines that the state should
15313 be transitioned to OUTSIDE_IT_BLOCK, a flag is marked to be closed
15314 after the tencode () function: that's what it_fsm_post_encode () does.
15316 Since in_it_block () calls the state handling function to get an
15317 updated state, an error may occur (due to invalid insns combination).
15318 In that case, inst.error is set.
15319 Therefore, inst.error has to be checked after the execution of
15320 the tencode () routine.
15322 3) Back in md_assemble(), it_fsm_post_encode () is called to commit
15323 any pending state change (if any) that didn't take place in
15324 handle_it_state () as explained above. */

21658 See if it's a processor-specific option.
21660 This routine is somewhat complicated by the need for backwards
21661 compatibility (since older releases of gcc can't be changed).
21662 The new options try to make the interface as compatible as
21665 New options (supported) are:
21667 -mcpu=<cpu name> Assemble for selected processor
21668 -march=<architecture name> Assemble for selected architecture
21669 -mfpu=<fpu architecture> Assemble for selected FPU.
21670 -EB/-mbig-endian Big-endian
21671 -EL/-mlittle-endian Little-endian
21672 -k Generate PIC code
21673 -mthumb Start in Thumb mode
21674 -mthumb-interwork Code supports ARM/Thumb interworking
21676 -m[no-]warn-deprecated Warn about deprecated features

21682 -macps-float Floats passed in FP registers
21683 -mapcs-reentrant Reentrant code
