We do end up eliminating it from the TUs object file, just inline limits try to limit program growth. Now the issue with the past heuristic is that if you have a very large .comdat function that is called once in a TU and once in another TU we think that inlining it in both TUs will decrease the size of the program. But in fact it does not as it wasn't really a function called once. Richard. > - FChE >
