             Bug #: 57221
           Summary: [4.8/4.9 regression] libgcc symbol visibility changes
                    break Android blobs
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libgcc
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: Bernhard.Rosenkranzer@linaro.org

Proposed fix

The changes in libgcc symbol visibilities that got into 4.8
(http://gcc.gnu.org/ml/gcc-patches/2012-08/msg01462.html) break important
Android blobs.

Bionic (Android's libc) has some rather weird hacks that expose libgcc.a's
__aeabi_uidiv and friends to applications linking to Bionic. The changed symbol
visibility breaks this, resulting in e.g. a Galaxy Nexus Android build done
with gcc 4.8 failing to boot to UI because it can't load its graphics drivers.

It may make sense to change symbol visibility back to default if the target is
Android. I've attached a patch that does that.
