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.

--- Comment #1 from Thomas De Schampheleire <[email protected]> 2013-10-21 06:33:01 UTC --- 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.
