I tries Linaro standard build. And I can not reproduce it with the options: -O2 -g -mfpu=neon -O3 -g -mfpu=neon
What's your option to compile the file?

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.olib/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:
