Hello,
I've recently faced an issue I'm afraid I currently unable to debug. When
building an arbitrary version of Linux kernel for powerpc-e500v2-linux-gnuspe
target, it seems gcc prior to 5 produces a good image which boots just fine, and
current gcc 5 snapshots (4.10.0-alpha20140810 for example) produce an image
which hangs just after U-Boot hands over to the kernel.
This behavior is well reproducible on real hardware as well as under qemu. I've
prepared a minimal kernel config which is dysfunctional as is but still enough
to demonstrate the problem in qemu. I believe the exact Linux version number
doesn't actually matter here, but see the attachment for details.
Compare the output produced by u-boot and this minified kernel build using
gcc 4.9.1 and 4.10.0-alpha20140810 snapshot.

I also have another seemingly related issue: kernel module built
w/ 4.10.0-alpha20140810 against a kernel configured
for powerpc-e500v2-linux-gnuspe snapshot lacks .gnu.linkonce.this_module and
.rela.gnu.linkonce.this_module sections. Current stable versions of gcc emit
these sections but also drop it (and, consequently, init_module() and
cleanup_module() symbols) when CFLAGS_MODULE is modified in any way, even w/
CFLAGS_MODULE="-mno-isel" for example.
I now have completely no idea what to do next to find a cause of (1) gcc 5
snapshots producing unbootable kernel, and (2) different gcc versions producing
garbled kernel modules when configured for SPE target. As for modules, I've
compared assembler output of gcc configured for powerpc-e300c3-linux-gnu and
powerpc-e500v2-linux-gnuspe and failed to spot real differences, but installed
version of binutils is exactly the same for both configurations, and I'm
completely sure my setup is correct.
Regards.
