Subject: Change target-wide-charset to UTF-16 on ppc-aix.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=38a69d0a4d05b7fb52902a3c9bd2360d7191af3b;p=binutils-gdb.git

Change target-wide-charset to UTF-16 on ppc-aix.

On ppc-aix, type wchar_t is 2 bytes long, so override the default
target-wide-charset (UTF-32) with UTF-16. This allows us to print
wide characters correctly.

gdb/ChangeLog:

        * rs6000-aix-tdep.c (rs6000_aix_auto_wide_charset): New function.
        (rs6000_aix_init_osabi): Set auto_wide_charset gdbarch method.
