 855    - if the table contains both assembler and disassembler functions then
 856      the disassembler contains much of the assembler and vice-versa,
 857    - there's a lot of inlining possibilities as things grow,
 858    - using a switch statement avoids the function call overhead.

1753 /* Main entry point.
1754    This routine is called for each instruction to be assembled.
1755    STR points to the insn to be assembled.
1756    We assume all necessary tables have been initialized.
1757    The assembled instruction, less any fixups, is stored in BUF.
1758    Remember that if CGEN_INT_INSN_P then BUF is an int and thus the value
1759    still needs to be converted to target byte order, otherwise BUF is an array
1760    of bytes in target byte order.
1761    The result is a pointer to the insn's entry in the opcode table,
1762    or NULL if an error occured (an error message will have already been
1763    printed).
1764
1765    Note that when processing (non-alias) macro-insns,
1766    this function recurses.
1767
1768    ??? It's possible to make this cpu-independent.
1769    One would have to deal with a few minor things.
1770    At this point in time doing so would be more of a curiosity than useful
1771    [for example this file isn't _that_ big], but keeping the possibility in
1772    mind helps keep the design clean.  */
