           Summary: [PowerPC] Buildroot uses wrong external toolchain
                    libraries for non-generic architecture variants
           Product: buildroot
           Version: 2013.08
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
        AssignedTo: unassigned at buildroot.uclibc.org
        ReportedBy: aleek998 at gmail.com
                CC: buildroot at uclibc.org
   Estimated Hours: 0.0


Using Codesoucery external toolchain, and architecture variant 8548 / e500v2,
toolchain libraries are copied from powerpc-linux-gnu/libc/nof but should be
copied from powerpc-linux-gnu/libc/te500v2. 

Library powerpc-linux-gnu/libc/nof/usr/lib/libstdc++.so contains 'lwsync'
instruction which is invalid on e500v2 and causes Invalid Instruction fault for
every c++ based application.

I tested the temporaty workaround (copying te500v2 dir to nof dir) and it
solved the bug.

I suppose that this bug might involve all PowerPC architecture variants.

Did you set BR2_TARGET_OPTIMIZATION ("Target optimizations") correctly in the
toolchain menu? The help text of the CodeSourcery toolchains mention this:

-------
- e500v2 glibc, 32 bits
  Set BR2_TARGET_OPTIMIZATION to -te500v2

If this does not work for you, feel free to discuss this problem on the mailing
list, IRC, or reopen this bug.
