>Description:
The following function, add<4,float>, is not inlined by g++ all versions including the online 3.0 from Code Sourcery (as of today 5/31/01).

<begin file add.cc>

#define SIZE 4

template <int N,class T> inline int add(T*a,T*b) {
  for (int i=0;i<N;i++) a[i]+=b[i];
  return(0);
}

int main(int argc,char *argv[]) {
  float a[SIZE], b[SIZE];
  for (int i=0;i<SIZE;i++) a[i]=b[i]=(float)i;

  add<SIZE>(a,b);
  return(0);
}

<end file add.cc>
>How-To-Repeat:
g++ -S add.cc
