[fpc-devel] Tail recursion optimization

[Florian Klaempfl]

Yesterday, I've implemented tail recursion optimization
(http://svn.freepascal.org/svn/fpc/trunk/compiler/opttail.pas resulting in
http://www.hu.freepascal.org/fpcircbot/cgipastebin?msgid=158 pp11 is the new
compiler, fpc11 the old, both are 2.1.1). It isn't enabled yet because it still
needs some fine tuning. The question is however when should it be enabled? With
-OoTAILREC? -O3? Something different?
