...owering calls to va_arg (http://old.nabble.com/va_arg-td25197836.html). However, I am developing an llvm backend (similar to the CBackend) that would like to handle va_arg as intrinsic from llvm-gcc. How can I modify llvm-gcc to generate the llvm va_arg instrinsic? With my little understanding of llvmg/gcc, I can try to modify the TARGET_GIMPLIFY_VA_ARG hook to create a new gcc builtin for va_arg and convert the tree code somehow to llvm in llvm-convert.c, EmitBuiltinCall(), but would really appreciate any advice on how to tackle the problem.

> 1. Clang - Jay, do you have a patch for this?  Can you create a branch of the clang repo or send an updated version of the patch to the list? I've created a clang type-system-rewrite branch and committed all my purely mechanical changes: de-constifying llvm::Types as necessary, and using the new llvm::StructType::createNamed/setBody to create the "implicit" structs used by

An update on the type-system-rewrite branch (http://llvm.org/viewvc/llvm-project/llvm/branches/type-system-rewrite/): It's now to the point where it passes all regression tests all of single source (and most of externals/multisource) when using an LLVM 2.9 version of clang to compile programs to a rbc file. I have what looks like one more subtle type mapping bug to track down, which will
