<pre>Given
// Type your code here, or load an example.
void test(int* dst, int count) {
dst = (int*)__builtin_assume_aligned(dst, 1024);
for(int i = 0; i != count; ++i)
dst[i] = 42;
}
normal clang -O3 -fno-unroll-loops does result in propagating of alignment
to store. But attributor fails to do that.
