             Bug #: 50090
           Summary: ARM EABI symbols in libgcc.a have default visibility
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: rsandifo@gcc.gnu.org


EABI functions like __aeabi_f2ulz are defined as aliases
of standard libgcc functions like __fixunssfdi.  In libgcc.a,
the standard function gets the correct hidden visibility,
but the alias retains default visibility.  This means that
DSOs linked against libgcc.a may end up exporting the
libgcc.a definition of __aeabi_f2ulz.

The bug is that bpabi-lib.h uses an asm statement to define
an alias, so the standard ways of forcing hidden visibility
at the C level have no effect.
