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]
