Hi all,

Looks like LLVM 2.6 was released:

<http://llvm.org/releases/2.6/docs/ReleaseNotes.html>

I'm just wondering what this means for Xcode users.  I imagine that
upcoming Xcodes will eventually include a newer llvm/clang, but until
then, is it wise/possible to update ourselves?

One thing that's been annoying for years is how's Xcode's gcc is always
so far behind the FSF's. With Apple's obvious involvement in LLVM, I'm
wondering if this will change.



I can't answer for the "wise" part, but it is possible.
I'm using an up-to-date version of clang/llvm with Xcode, and although I'm pretty sure it's "not supported", it works quite well.
llvm 2.6 is a stable released, but as clang has not really reached it's first full feature version, I prefer working with the trunk version (the LLVM and clang teams do their best to maintain a clean and working TOT).


You just have to replace 2 files and 1 directory in your developer folder.

/Developer/usr/bin/clang
/Developer/usr/libexec/clang-cc

/Developer/usr/lib/clang/

And just keep a backup version of this 3 files, so you will be able to revert if something goes wrong.
