Subject: crtbegin.asm (dtor_ptr): Make gp-relative.
X-Git-Tag: prereleases/libstdc++-3.0.95~2559
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3dff7ed031b733e5472f5d2bc39a3c846c395cbc;p=thirdparty%2Fgcc.git

crtbegin.asm (dtor_ptr): Make gp-relative.

        * config/ia64/crtbegin.asm (dtor_ptr): Make gp-relative.
        (__do_global_dtors_aux): Update to match.
        (__JCR_LIST__, __do_jv_register_classes): New.
        (.init): Call it.
        * config/ia64/crtend.asm (__JCR_END__): New.
        (__do_global_ctors_aux): Use a GPREL64I reloc to __CTOR_END__
        instead of an indirect LTOFF22 reloc.
