LLVM's TCO is fully functional on x86 and x64 but I'm not sure about DEC Alpha, ARM, Blackfin, Cell, MIPS, CIL, MSP430, 16-bit PIC, PowerPC, Sparc and XCore. > and I believe it optimizes only tail recursion, not general tail calls. No, that is definitely incorrect. TCO was very important to me when I was trying to choose a foundation to build upon and I carefully tested several options including the JVM, Mono and LLVM. LLVM was the only choice to offer real TCO at the time. AFAIK, OpenJDK now offers full TCO (implemented by the same guy) and Mono's implementation is still fundamentally broken. -- Dr Jon Harrop, Flying Frog Consultancy Ltd. http://www.ffconsultancy.com/?e -- You received this message because you are subscribed to the Google Groups "JVM Languages" group.
