* Andrew Burgess <andrew.burgess@embecosm.com> [2019-07-27 17:22:33 +0100]:
> Currently the 'info types' command will return symbols that correspond
> to Fortran modules. This because the symbols are created with domain
> MODULE_DOMAIN, but address_class LOC_TYPEDEF, which is the same
> address_class as type symbols.
>
> This commit explicitly prevents MODULE_DOMAIN symbols from appearing
> when we search for symbols in the TYPES_DOMAIN, this prevents the
> module symbols from appearing in the output of 'info types'.
>
> gdb/ChangeLog:
>
> * symtab.c (search_symbols): Don't include MODULE_DOMAIN symbols
> when searching for types.
>
> gdb/testsuite/ChangeLog:
>
> * gdb.fortran/info-types.exp: Add module.
> * gdb.fortran/info-types.f90: Update expected results.
I've now pushed this patch as it only depended on the previous patch
in this series.
Thanks,
Andrew
