Description Simen Kjaeraas 2017-01-18 14:32:04 UTC 
Test case:

module foo;
import core.simd;

struct bug {
    float4 value;
    
    this(float4 ) {
    }
    
    auto normalize() {
        bug t1 = __simd(XMM.DPPS, value, value);
        value = __simd(XMM.MULPS, value);
        return this;
    }
}


command line: dmd -m64 -O foo.d
