Description Martin Nowak 2011年07月08日 13:56:34 UTC 
class XMMPainter
{
 float call()
 {
 return sumFloats(0.0f, 0.0f);
 }
 static float sumFloats(float a, float b)
 {
 return a + b;
 }
}
void testXMM()
{
 auto painter = new XMMPainter;
 assert(XMMPainter.sumFloats(20, painter.call()) == 20.0f);
}
---
The expression painter.call() is evaluated after 20 has been loaded into xmm1, but the register is not saved.
