3.0 does not implement a few builtins that are used in this library. We
recommend using the system GCC to compile LLVM and Clang in this case.
+**Clang 3.0 on Mageia 2**. There's a packaging issue: Clang can not find at
+least some (``cxxabi.h``) libstdc++ headers.

Binary release of the llvm-gcc-4.2 front end for a specific platform.
+.. _checkout:
+
Checkout LLVM from Subversion
-----------------------------
``checkout`` each working branch individually and ``rebase`` it on top of its
parent branch.
+For those who wish to be able to update an llvm repo in a simpler fashion,
+consider placing the following git script in your path under the name
+``git-svnup``:
+
+.. code-block:: bash
+
+ #!/bin/bash
+
+ STATUS=$(git status -s | grep -v "??")
+
+ if [ ! -z "$STATUS" ]; then
+ STASH="yes"
+ git stash >/dev/null
+ fi
+
+ git fetch
+ OLD_BRANCH=$(git rev-parse --abbrev-ref HEAD)
+ git checkout master 2> /dev/null
+ git svn rebase -l
+ git checkout $OLD_BRANCH 2> /dev/null
+
+ if [ ! -z $STASH ]; then
+ git stash pop >/dev/null
+ fi
+
+Then to perform the aforementioned update steps go into your source directory
+and just type ``git-svnup`` or ``git svnup`` and everything will just work.
+
To commit back changes via git-svn, use ``dcommit``:
.. code-block:: console
