Re: Java Compilers and Tail Recursion

If a tail-recursive method does not violate the security policy, there
is no reason why the optimized version will. So the compiler can
surely optimize it.


As to whether compilers actually do, I dont know. But I do know that
the Microsoft JIT compiler optimizes tail recursion.


Many of the Java compilers do not perform good optimizations. Its
mostly lazy programming. But also note that many optimizations are
best not done as it impedes the JIT compiler in generation of good
native code. But tail- recursion is not such a case, and should surely
be optimized.
