13745 /* Subroutine of md_assemble, responsible for looking up the primary

13749 This is not simply a hash table lookup, because of conditional
13750 variants. Most instructions have conditional variants, which are
13751 expressed with a _conditional affix_ to the mnemonic. If we were
13752 to encode each conditional variant as a literal string in the opcode
13753 table, it would have approximately 20,000 entries.
13755 Most mnemonics take this affix as a suffix, and in unified syntax,
13756 'most' is upgraded to 'all'. However, in the divided syntax, some
13757 instructions take the affix as an infix, notably the s-variants of
13758 the arithmetic instructions. Of those instructions, all but six
13759 have the infix appear after the third character of the mnemonic.
13761 Accordingly, the algorithm for looking up primary opcodes given
13764 1. Look up the identifier in the opcode table.
13765 If we find a match, go to step U.
13767 2. Look up the last two characters of the identifier in the
13768 conditions table. If we find a match, look up the first N-2
13769 characters of the identifier in the opcode table. If we
13770 find a match, go to step CE.
13772 3. Look up the fourth and fifth characters of the identifier in
13773 the conditions table. If we find a match, extract those
13774 characters from the identifier, and look up the remaining
13775 characters in the opcode table. If we find a match, go
13780 U. Examine the tag field of the opcode structure, in case this is
13781 one of the six instructions with its conditional infix in an
13782 unusual place. If it is, the tag tells us where to find the
13783 infix; look it up in the conditions table and set inst.cond
13784 accordingly. Otherwise, this is an unconditional instruction.
13785 Again set inst.cond accordingly. Return the opcode structure.
13787 CE. Examine the tag field to make sure this is an instruction that
13788 should receive a conditional suffix. If it is not, fail.
13789 Otherwise, set inst.cond from the suffix we already looked up,
13790 and return the opcode structure.
13792 CM. Examine the tag field to make sure this is an instruction that
13793 should receive a conditional infix after the third character.
13794 If it is not, fail. Otherwise, undo the edits to the current
13795 line of input and proceed as for case CE. */

19498 See if it's a processor-specific option.
19500 This routine is somewhat complicated by the need for backwards
19501 compatibility (since older releases of gcc can't be changed).
19502 The new options try to make the interface as compatible as
19505 New options (supported) are:
19507 -mcpu=<cpu name> Assemble for selected processor
19508 -march=<architecture name> Assemble for selected architecture
19509 -mfpu=<fpu architecture> Assemble for selected FPU.
19510 -EB/-mbig-endian Big-endian
19511 -EL/-mlittle-endian Little-endian
19512 -k Generate PIC code
19513 -mthumb Start in Thumb mode
19514 -mthumb-interwork Code supports ARM/Thumb interworking
19516 For now we will also provide support for:
19518 -mapcs-32 32-bit Program counter
19519 -mapcs-26 26-bit Program counter
19520 -macps-float Floats passed in FP registers
19521 -mapcs-reentrant Reentrant code
19523 (sometime these will probably be replaced with -mapcs=<list of options>
19524 and -matpcs=<list of options>)
19526 The remaining options are only supported for back-wards compatibility.
19527 Cpu variants, the arm part is optional:
19528 -m[arm]1 Currently not supported.
19529 -m[arm]2, -m[arm]250 Arm 2 and Arm 250 processor
19530 -m[arm]3 Arm 3 processor
19531 -m[arm]6[xx], Arm 6 processors

19535 -mstrongarm[110[0]] StrongARM processors
19536 -mxscale XScale processors
19537 -m[arm]v[2345[t[e]]] Arm architectures
19538 -mall All (except the ARM1)
19540 -mfpa10, -mfpa11 FPA10 and 11 co-processor instructions
19541 -mfpe-old (No float load/store multiples)
