            Bug ID: 107878
           Summary: Incomplete documentation for H8/300
           Product: gcc
           Version: 12.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jdx at o2 dot pl
  Target Milestone: ---

Documentation on
https://gcc.gnu.org/onlinedocs/gcc-12.2.0/gcc/H8_002f300-Options.html is not
consistent with <SRC_ROOT>/gcc/config/h8300/h8300.opt.

E.g. -msx option is not mentioned on the webpage.

Confirmed, gcc/gcc/doc/invoke.texi lists -ms but not -msx

--- Comment #2 from Jan Dubiec <jdx at o2 dot pl> ---
One more thing – the documentation on the webpage states that -mn "must be used
either with -mh or -ms". It is true for old compilers (e.g. for gcc 4.7 which I
still use) but does not seem to be true for new ones, i.e. it is possible pass
-mn alone at least to gcc 12.2. BTW. As far as I can see support for H8/300
(pure 16-bit MCUs, do not confuse with H8/300H) has been (justifiably) removed
since mid-2020 – IMO it is worth to mention about that fact in the
documentation.
