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