[LLVMdev] NEON intrinsics preventing redundant load optimization?
...this case anyway, but that wasn't true for my real situation) then the temporary "result" seems to be kept in the generated code for the test function, and triggers the bad penalty of a load after a NEON store.
vec4 operator* (vec4& a, vec4& b)
{
vec4 result;
float32x4_t result_data = vmulq_f32(vld1q_f32(a.data), vld1q_f32(b.data));
vst1q_f32(result.data, result_data);
return result;
}
