             Bug #: 55571
           Summary: [4.6.4 regression] PR48076 fix broke bootstrap on
                    armv5tel-linux-gnueabi
    Classification: Unclassified
           Product: gcc
           Version: 4.6.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: mikpe@it.uu.se


Attempting to bootstrap gcc-4.6-20121130 on armv5tel-linux-gnueabi fails with:

This is a recent regression, caused by the PR48076 fix backport in r193959. 
Reverting that revision allows the bootstrap to complete.

Note that the __sync_ primitives on arm-linux-gnueabi reside in the static
libgcc.a, not the shared libgcc_s.so.1.
