All, So far I've tried LLVM on amd64, i386, ia64 and powerpc under FreeBSD and aside for ia64, things look pretty good for a first try. There are 2 unexpected failures for PowerPC, which appear to be caused by uninitialized memory. I'm still working on a fix for that (need to brush up on my C++ skills). [sidenote: In FreeBSD -current, the memory allocator initializes memory with 0xa5
