==================

The reduced testcase looks something like this
(previous r203169 is able to compile it):

#include <emmintrin.h>

void testFunc(int count) {

  int x;
  __m128i tmp1;
  __asm__(
                  "1:\n"
                  :"+d"(x)
                  :[count] "m" (count), [tmp1] "m" (tmp1)
                  :"ecx","esi","edi","eax"
          );
}

The compiling options:
gcc test.c -c -fPIC -mstackrealign -march=core-avx2 -m32
