From what I can see in the Linaro report this has been fixed.
I can't reproduce it on 4.10 trunk or 4.8.3

I have some additional info related to this bug:

If I compile the following:

#include arm_neon.h
#include stdlib.h

int main ()
{
   float r [] = {0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f};
   float32x4x2_t d;
   d = vld2q_f32 (r);
   vst2q_f32 (r, d);
   return 0;
}

using: arm-linux-androideabi-gcc test.c -mfloat-abi=softfp -mfpu=neon -g -O1

I get:
test.c: In function 'main':
test.c:4:5: internal compiler error: in immed_double_const, at emit-rtl.c:550
Please submit a full bug report,
with preprocessed source if appropriate.
See http://gcc.gnu.org/bugs.html for instructions.

However, if I comment out vst2q_f32 (r, d);, the problem goes away. Also by not
using -g or -O1.
