Subject:         * config/tc-hppa.c (hppa_fix_struct): Add new "segment" field.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fca59f9d42e32d441760c1c0e182dcd98fbee7f0;p=binutils-gdb.git

    * config/tc-hppa.c (hppa_fix_struct): Add new "segment" field.
        (hppa_fix_new): Initialize segment field.
        (md_apply_fix): Do nothing for pc-relative fixup which involves
        crossing a segment boundary.
        (pa_procend): Undefine the current label after handling .PROC
        and .PROCEND directives.
        (dummy_symbol): Make type "symbolS *".  Change references as
        appropriate.
