------- Additional Comments From roger dot larsson at norran dot net  2004-01-19 08:11 -------
This is the shortest code yet (matrix.cpp) I found that generates the 
offending instruction (movaps) - but I have not yet succeeded in getting 
the stack unaligned... [Do you need that too?] 
 
class RTime 
{ 
public: 
    int minute() {} 
}; 
 
void rotate(float x) 
{ 
} 
 
int main() 
{ 
    RTime _time; 
 
    // hour 
    float h_angle = _time.minute(); 
    rotate(-h_angle); 
 
    // minute 
    float m_angle = _time.minute(); 
    rotate(-m_angle); 
} 
 
I am pretty sure that Qt should be simple to  
Compile with: 
gcc -I/usr/src/kde/qt-copy/mkspecs/linux-g++ -I../../include -o matrix.o 
-march=pentium3 -O1 matrix.cpp
