> The "--help" option of as misses the option "al", "dump-config",
> "emulation", "gdwarf-cie-version", "hash-size", "itbl",
> "reduce-memory-overheads", "multibyte-handling", "mbig-obj", "O". 

Several of these options are included in the --help output, just in different
forms:

1) -al is listed under the -a option.  (The -a option can be followed by
multiple letters to control the behaviour of the listing feature).

3) The "emulation" option is listed as "-em=[" followed by a list of supported
emulation.  Technically this is sufficient as the option parsing code will
accepted shortened forms of long option names as long as they are unique.  But
it would be better if the --help output matched the full name, so I will fix
this.

6) The "itbl" option is listed, but only if ITBL support has been enabled in
the assembler.

9) The "-mbig-obj" option is listed, but only of the TE_PE or TE_PEP target
environment defines have been enabled.


As for the others, you are correct.  Their description is missing and I will
create a patch to fix this.

Cheers
  Nick
