As of yesterday, clang static-checking support has been checked into
the tree. To use it, compile with clang 3.2 (tip-of-trunk may or may
not work) and --enable-clang-plugin on a Linux machine. Mac support is
currently not enabled since I don't own a Mac and the build system for
this kind of stuff is really, really crappy. It is also not yet usable
on try for reasons to do with header incompatibilities, although this
will appear to be resolvable within a day or two if things go well.
This is now usable on try. The current complicated steps to do so are:
1. Copy browser/config/tooltool-manifests/linux64/clang.manifest to
browser/config/tooltool-manifests/linux64/releng.manifest (you can also
do the same for linux32).
2. Edit build/unix/mozconfig.linux to use clang instead of gcc as the
compiler, and to add --enable-clang-plugin to the list of options. It
should look as follows:
if [ -d "$topsrcdir/clang" ]; then
# mozilla-central based build
export CC=$topsrcdir/clang/bin/clang
export CXX=$topsrcdir/clang/bin/clang++
export LLVMCONFIG=$topsrcdir/clang/bin/llvm-config
elif [ -d "$topsrcdir/../clang" ]; then
# comm-central based build
export CC=$topsrcdir/../clang/bin/clang
export CXX=$topsrcdir/../clang/bin/clang++
export LLVMCONFIG=$topsrcdir/../clang/bin/llvm-config
fi
ac_add_options --enable-clang-plugin
3. Push to try that builds on Linux64, debug or opt.
I am currently working with releng to make this process less painful by
getting a builder that is dedicated to running these sorts of steps. See
bug 851753 for current progress.
As a side note, I will point out that we already have our first static
checking failure checked into the tree, thanks to bug 840417.
