Please report a bug again linaro toolchain with the test case and cmd
line options at https://bugs.launchpad.net/gcc-linaro
Ok, filed as https://bugs.launchpad.net/gcc-linaro/+bug/1268893
If this blocks your work, please remove "-g' option to workaround it.
Thanks for the hint!

Koen
Thanks!

Can you attach the preprocessed C file? Add option --save-temps to
compile neon4 source file. Then you will get a temp file neon4.i

Hi,
I've been playing with linux-linaro-tracking and the 2013.12 (and
2013.10,
2013.11) toolchain release and when turning on the NEON in kernel
option
I
get:
CC lib/raid6/neon4.o
lib/raid6/neon4.c: In function 'raid6_neon4_gen_syndrome_real':
lib/raid6/neon4.c:113:1: internal compiler error: in
dwarf2out_frame_debug_adjust_cfa, at dwarf2cfi.c:1078
}
^
Use the attached .txt as .config and do 'make zImage' to replicate the
problem. You will probably need to attached patch as well since some
of
the
linaro patches break namespace support :(
I believe the kernel build system can get you the pre-processed source
with, e.g.:
# make lib/raid6/neon4.i
The kernel does support that, which makes this a lot easier. Neon4.i is
attached.
I forgot to mention, this is with gcc 4.8:
[koen@macbook linux-linaro-tracking]$ !arm
arm-angstrom-linux-gnueabi-gcc -v
Using built-in specs.
