inlining problems

[Thomas Heller]

Hi list,

I ran into a little issue when trying to force inlining with 
__attribute__(( always_inline )). The reason why i am trying to force
the compiler to inline my code is simple: I want to implement handwritten
optimizations using SSE intrinsics. However it seems that gcc is not willing 
to inline that code anymore. That is why i came up with the idea of trying to 
force gcc.
There is a problem now. I get tons of error messages that gcc is not able to 
inline that function.
Example error message:
sorry, unimplemented: inlining failed in call to ‘const pe::Vector3<typename 
pe::MathTrait<T1, T2, true>::AddType> pe::operator+(const pe::Vector3<Type>&, 
const pe::Vector3<T2>&) [with T1 = double, T2 = double]’: function not 
inlinable

I was trying to put that in a little testcase. However it seems that i can't 
reproduce that error with a small code base.
Any ideas? Need more information?

Thanks,
Thomas
