The following testcase used to work in 4.1.1 but no longer does:

#define vector __attribute__((vector_size(16) ))
template<int INDEX>
vector signed int MyFunction(vector float value)  {}

template<int>
void MyFunction(float ){}

int main()
{
    vector float myVector;
    float myFloat;
    MyFunction<1>(myVector);
    MyFunction<1>(myFloat);
}

---- CUT ----
We get:
vector14.C: In function ‘int main()’:
vector14.C:12: error: no matching function for call to ‘MyFunction(float
__vector__&)’
vector14.C:13: error: call of overloaded ‘MyFunction(float&)’ is ambiguous
vector14.C:3: note: candidates are: int MyFunction(float) [with int INDEX = 1]
vector14.C:6: note:                 void MyFunction(float) [with int
<anonymous> = 1]
