21931 The documentation says that the Q registers are encoded as 2*N in the D:Vd
21932 bits (or equivalent for N and M registers).
21933 Similarly the D registers are encoded as N in D:Vd bits.
21934 While the S registers are encoded as N in the Vd:D bits.
21936 Taking into account the maximum values of these registers we can see a
21937 nicer pattern for calculation:
21938 Q -> 7, D -> 15, S -> 31
21940 If we say that everything is encoded in the Vd:D bits, then we can say
21941 that Q is encoded as 4*N, and D is encoded as 2*N.
21942 This way the bits will end up the same, and calculation is simpler.
21943 (calculation is now:
21944 1. Multiply by a number determined by the register letter.
21945 2. Encode resulting number in Vd:D bits.)
21947 This is made a little more complicated by automatic handling of 'Q'
21948 registers elsewhere, which means the register number is already 2*N where
21949 N is the number the user wrote after the register letter.

22523 This is not simply a hash table lookup, because of conditional
22524 variants. Most instructions have conditional variants, which are
22525 expressed with a _conditional affix_ to the mnemonic. If we were
22526 to encode each conditional variant as a literal string in the opcode
22527 table, it would have approximately 20,000 entries.
22529 Most mnemonics take this affix as a suffix, and in unified syntax,
22530 'most' is upgraded to 'all'. However, in the divided syntax, some
22531 instructions take the affix as an infix, notably the s-variants of
22532 the arithmetic instructions. Of those instructions, all but six
22533 have the infix appear after the third character of the mnemonic.
22535 Accordingly, the algorithm for looking up primary opcodes given
22538 1. Look up the identifier in the opcode table.
22539 If we find a match, go to step U.
22541 2. Look up the last two characters of the identifier in the
22542 conditions table. If we find a match, look up the first N-2
22543 characters of the identifier in the opcode table. If we
22544 find a match, go to step CE.
22546 3. Look up the fourth and fifth characters of the identifier in
22547 the conditions table. If we find a match, extract those
22548 characters from the identifier, and look up the remaining
22549 characters in the opcode table. If we find a match, go
22554 U. Examine the tag field of the opcode structure, in case this is
22555 one of the six instructions with its conditional infix in an
22556 unusual place. If it is, the tag tells us where to find the
22557 infix; look it up in the conditions table and set inst.cond
22558 accordingly. Otherwise, this is an unconditional instruction.
22559 Again set inst.cond accordingly. Return the opcode structure.
22561 CE. Examine the tag field to make sure this is an instruction that
22562 should receive a conditional suffix. If it is not, fail.
22563 Otherwise, set inst.cond from the suffix we already looked up,
22564 and return the opcode structure.
22566 CM. Examine the tag field to make sure this is an instruction that
22567 should receive a conditional infix after the third character.
22568 If it is not, fail. Otherwise, undo the edits to the current
22569 line of input and proceed as for case CE. */

22805 in_pred_block () ditto
22806 it_fsm_post_encode () from md_assemble ()
22807 force_automatic_it_block_close () from label handling functions
22810 1) md_assemble () calls it_fsm_pre_encode () before calling tencode (),
22811 initializing the IT insn type with a generic initial value depending
22812 on the inst.condition.
22813 2) During the tencode function, two things may happen:
22814 a) The tencode function overrides the IT insn type by
22815 calling either set_pred_insn_type (type) or
22816 set_pred_insn_type_last ().
22817 b) The tencode function queries the IT block state by
22818 calling in_pred_block () (i.e. to determine narrow/not narrow mode).
22820 Both set_pred_insn_type and in_pred_block run the internal FSM state
22821 handling function (handle_pred_state), because: a) setting the IT insn
22822 type may incur in an invalid state (exiting the function),
22823 and b) querying the state requires the FSM to be updated.
22824 Specifically we want to avoid creating an IT block for conditional
22825 branches, so it_fsm_pre_encode is actually a guess and we can't
22826 determine whether an IT block is required until the tencode () routine
22827 has decided what type of instruction this actually it.
22828 Because of this, if set_pred_insn_type and in_pred_block have to be
22829 used, set_pred_insn_type has to be called first.
22831 set_pred_insn_type_last () is a wrapper of set_pred_insn_type (type),
22832 that determines the insn IT type depending on the inst.cond code.
22833 When a tencode () routine encodes an instruction that can be
22834 either outside an IT block, or, in the case of being inside, has to be
22835 the last one, set_pred_insn_type_last () will determine the proper
22836 IT instruction type based on the inst.cond code. Otherwise,
22837 set_pred_insn_type can be called for overriding that logic or
22838 for covering other cases.
22840 Calling handle_pred_state () may not transition the IT block state to
22841 OUTSIDE_PRED_BLOCK immediately, since the (current) state could be
22842 still queried. Instead, if the FSM determines that the state should
22843 be transitioned to OUTSIDE_PRED_BLOCK, a flag is marked to be closed
22844 after the tencode () function: that's what it_fsm_post_encode () does.
22846 Since in_pred_block () calls the state handling function to get an
22847 updated state, an error may occur (due to invalid insns combination).
22848 In that case, inst.error is set.
22849 Therefore, inst.error has to be checked after the execution of
22850 the tencode () routine.
22852 3) Back in md_assemble(), it_fsm_post_encode () is called to commit
22853 any pending state change (if any) that didn't take place in
22854 handle_pred_state () as explained above. */

30945 Invocation line includes a switch not recognized by the base assembler.
30946 See if it's a processor-specific option.
30948 This routine is somewhat complicated by the need for backwards
30949 compatibility (since older releases of gcc can't be changed).
30950 The new options try to make the interface as compatible as
30953 New options (supported) are:
30955 -mcpu=<cpu name> Assemble for selected processor
30956 -march=<architecture name> Assemble for selected architecture
30957 -mfpu=<fpu architecture> Assemble for selected FPU.
30958 -EB/-mbig-endian Big-endian
30959 -EL/-mlittle-endian Little-endian
30960 -k Generate PIC code
30961 -mthumb Start in Thumb mode
30962 -mthumb-interwork Code supports ARM/Thumb interworking
30964 -m[no-]warn-deprecated Warn about deprecated features
30965 -m[no-]warn-syms Warn when symbols match instructions
30967 For now we will also provide support for:
30969 -mapcs-32 32-bit Program counter
30970 -mapcs-26 26-bit Program counter
30971 -macps-float Floats passed in FP registers
30972 -mapcs-reentrant Reentrant code
30974 (sometime these will probably be replaced with -mapcs=<list of options>
30975 and -matpcs=<list of options>)
30977 The remaining options are only supported for back-wards compatibility.
30978 Cpu variants, the arm part is optional:
30979 -m[arm]1 Currently not supported.
30980 -m[arm]2, -m[arm]250 Arm 2 and Arm 250 processor
30981 -m[arm]3 Arm 3 processor
30982 -m[arm]6[xx], Arm 6 processors
30983 -m[arm]7[xx][t][[d]m] Arm 7 processors
30984 -m[arm]8[10] Arm 8 processors
30985 -m[arm]9[20][tdmi] Arm 9 processors
30986 -mstrongarm[110[0]] StrongARM processors
30987 -mxscale XScale processors
30988 -m[arm]v[2345[t[e]]] Arm architectures
30989 -mall All (except the ARM1)
30991 -mfpa10, -mfpa11 FPA10 and 11 co-processor instructions
30992 -mfpe-old (No float load/store multiples)
