It seems that some code in libgloss accesses this stuff directly: libgloss/epiphany/crt0.S: add r2,r2,need_to_find_out; &_GLOBAL_REENT->atexit0 libgloss/epiphany/crt0.S: str r2, [r2,-1];??or -2?; _GLOBAL_REENT->atexit libgloss/epiphany/crt0.S: str r0, [r2,1] ; _GLOBAL_REENT->atexit0._ind libgloss/epiphany/crt0.S: str r1, [r2,2] ; _GLOBAL_REENT->atexit0._fns[0] libgloss/epiphany/crt0.S: add r0,r2,0x14c ; &_GLOBAL_REENT->atexit0 libgloss/epiphany/crt0.S: str r0, [r0,-1] ; _GLOBAL_REENT->atexit libgloss/epiphany/crt0.S: strd r0, [r2,0x2a] ; _GLOBAL_REENT->atexit0._ind libgloss/arc/crt0.S: add r1, r1, 0x14c ; &_GLOBAL_REENT->atexit0 libgloss/arc/crt0.S: st r1, [r1, -4] ; _GLOBAL_REENT->atexit libgloss/arc/crt0.S: st_s r0, [r1, 8] ; _GLOBAL_REENT->atexit0._fns[0] libgloss/arc/crt0.S: st_s r0, [r1, 4] ; _GLOBAL_REENT->atexit0._ind libgloss/sparc_leon/locore_atexit.c: p = _GLOBAL_REENT->_atexit; libgloss/sparc_leon/locore_atexit.c: _GLOBAL_REENT->_atexit = p = &_GLOBAL_REENT->_atexit0; I will update it if the patch is acceptable in general. -- embedded brains GmbH Herr Sebastian HUBER Dornierstr. 4 82178 Puchheim Germany email: [email protected] phone: +49-89-18 94 741 - 16 fax: +49-89-18 94 741 - 08 Registergericht: Amtsgericht München Registernummer: HRB 157899 Vertretungsberechtigte Geschäftsführer: Peter Rasmussen, Thomas Dörfler Unsere Datenschutzerklärung finden Sie hier: https://embedded-brains.de/datenschutzerklaerung/
