I can not test it on my box 'cause llvm-gcc does not compile on Linux/PPC, but the llvm.org online demo does not indeed generate a llvvm.vaarg instruction. But this is horribly not portable! The va_arg(ap, int) for Linux/PPC is really different from Darwin/PPC (see my previous message). And the .ll file generated by llvm-gcc can not be executed on Linux/PPC. Btw, I'm using the JIT of llvm, not llvm-gcc, I do not code in C to...

Hi everyone, I'm implementing varags handling for PPC32 with the ELF ABI. It is largely more complicated than the Macho ABI or x86 because it manipulates a struct instead of a direct pointer in the stack. You can find the layout of the va_list struct at the end of this mail. A VAARG call requires a lot of computation. Typically the C code for va_arg(ap, int) is: int va_arg_gpr(ap_list

Hi Talin, I have some questions below. If these topics have already been discussed in earlier threads, kindly point me there. I'm aware of your GC proposal, but the rest is new to me.

The biggest problem is the inability to track SSA values - it requires the frontend to generate very inefficient and

So I've been using LLVM for about 4 years now, and I've posted a lot on this list about specific issues. What I would like to do is step back for a moment and give my "big picture" assessment of LLVM overall, particularly with respect to developing a "managed" language like Java / C# or my own language, Tart. Obviously, I feel that LLVM is the best choice out there,
