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.
