7365 beginning of the mnemonic.
7367 This is not simply a hash table lookup, because of conditional
7368 variants. Most instructions have conditional variants, which are
7369 expressed with a _conditional affix_ to the mnemonic. If we were
7370 to encode each conditional variant as a literal string in the opcode
7371 table, it would have approximately 20,000 entries.
7373 Most mnemonics take this affix as a suffix, and in unified syntax,
7374 'most' is upgraded to 'all'. However, in the divided syntax, some
7375 instructions take the affix as an infix, notably the s-variants of
7376 the arithmetic instructions. Of those instructions, all but six
7377 have the infix appear after the third character of the mnemonic.
7379 Accordingly, the algorithm for looking up primary opcodes given
7382 1. Look up the identifier in the opcode table.
7383 If we find a match, go to step U.
7385 2. Look up the last two characters of the identifier in the
7386 conditions table. If we find a match, look up the first N-2
7387 characters of the identifier in the opcode table. If we
7388 find a match, go to step CE.
7390 3. Look up the fourth and fifth characters of the identifier in
7391 the conditions table. If we find a match, extract those
7392 characters from the identifier, and look up the remaining
7393 characters in the opcode table. If we find a match, go
7398 U. Examine the tag field of the opcode structure, in case this is
7399 one of the six instructions with its conditional infix in an
7400 unusual place. If it is, the tag tells us where to find the
7401 infix; look it up in the conditions table and set inst.cond
7402 accordingly. Otherwise, this is an unconditional instruction.
7403 Again set inst.cond accordingly. Return the opcode structure.
7405 CE. Examine the tag field to make sure this is an instruction that
7406 should receive a conditional suffix. If it is not, fail.
7407 Otherwise, set inst.cond from the suffix we already looked up,
7408 and return the opcode structure.
7410 CM. Examine the tag field to make sure this is an instruction that
7411 should receive a conditional infix after the third character.
7412 If it is not, fail. Otherwise, undo the edits to the current
7413 line of input and proceed as for case CE. */

11595 -EB/-mbig-endian Big-endian
11596 -EL/-mlittle-endian Little-endian
11597 -k Generate PIC code
11598 -mthumb Start in Thumb mode
