             Bug #: 15500
           Summary: ARM __aeabi_localeconv incorrect
           Product: glibc
           Version: 2.17
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ports
        AssignedTo: unassigned@sourceware.org
        ReportedBy: jsm28@gcc.gnu.org
                CC: carlos@redhat.com, roland@gnu.org
    Classification: Unclassified


ARM glibc's __aeabi_localeconv does:

struct lconv *
__aeabi_localeconv (void)
{
  return __localeconv ();
}

However, glibc orders the C99 fields in struct lconv thus:

  char int_p_cs_precedes;
  char int_p_sep_by_space;
  char int_n_cs_precedes;
  char int_n_sep_by_space;
  char int_p_sign_posn;
  char int_n_sign_posn;

but the __aeabi_lconv structure (defined in CLIBABI, ARM IHI 0039) has them
ordered thus:

  char int_p_cs_precedes;
  char int_n_cs_precedes;
  char int_p_sep_by_space;
  char int_n_sep_by_space;
  char int_p_sign_posn;
  char int_n_sign_posn;

and so a conversion layer is needed to swap int_p_sep_by_space and
int_n_cs_precedes.
