13843 /* Subroutine of md_assemble, responsible for looking up the primary

13847 This is not simply a hash table lookup, because of conditional
13848 variants. Most instructions have conditional variants, which are
13849 expressed with a _conditional affix_ to the mnemonic. If we were
13850 to encode each conditional variant as a literal string in the opcode
13851 table, it would have approximately 20,000 entries.
13853 Most mnemonics take this affix as a suffix, and in unified syntax,
13854 'most' is upgraded to 'all'. However, in the divided syntax, some
13855 instructions take the affix as an infix, notably the s-variants of
13856 the arithmetic instructions. Of those instructions, all but six
13857 have the infix appear after the third character of the mnemonic.
13859 Accordingly, the algorithm for looking up primary opcodes given
13862 1. Look up the identifier in the opcode table.
13863 If we find a match, go to step U.
13865 2. Look up the last two characters of the identifier in the
13866 conditions table. If we find a match, look up the first N-2
13867 characters of the identifier in the opcode table. If we
13868 find a match, go to step CE.
13870 3. Look up the fourth and fifth characters of the identifier in
13871 the conditions table. If we find a match, extract those
13872 characters from the identifier, and look up the remaining
13873 characters in the opcode table. If we find a match, go
13878 U. Examine the tag field of the opcode structure, in case this is
13879 one of the six instructions with its conditional infix in an
13880 unusual place. If it is, the tag tells us where to find the
13881 infix; look it up in the conditions table and set inst.cond
13882 accordingly. Otherwise, this is an unconditional instruction.
13883 Again set inst.cond accordingly. Return the opcode structure.
13885 CE. Examine the tag field to make sure this is an instruction that
13886 should receive a conditional suffix. If it is not, fail.
13887 Otherwise, set inst.cond from the suffix we already looked up,
13888 and return the opcode structure.
13890 CM. Examine the tag field to make sure this is an instruction that
13891 should receive a conditional infix after the third character.
13892 If it is not, fail. Otherwise, undo the edits to the current
13893 line of input and proceed as for case CE. */

14261 If the address stored at .Laaa is that of a symbol which has the

14263 to have the bottom bit set, which in turn would mean that the

19613 This routine is somewhat complicated by the need for backwards

19623 -EB/-mbig-endian Big-endian
19624 -EL/-mlittle-endian Little-endian
19625 -k Generate PIC code
19626 -mthumb Start in Thumb mode
