VisitCompoundStmt correctly substitutes the child Stmts. When calling Visit() on a Stmt, this substitution needs to be carried out by the caller: only it knows what target type to request. This fixes the issue for if statements which do not fall back to VisitStmt() because of the conditional being of bool type. In principle we are still missing do / while statements, too - again due to the conditional part.

##DESCRIPTION
Cling is an interactive C++ interpreter, built on top of Clang and LLVM compiler infrastructure. Cling realizes the read-print-evaluate-loop concept, in order to leverage rapid application development. Implemented as a small extension to LLVM and Clang, the interpreter reuses their strengths such as the praised concise and expressive compiler diagnostics.

##INSTALLATION
###Binaries
We offer binary snapshots for download at https://ecsft.cern.ch/dist/cling
###Source
CLING source depends on the LLVM[1] and CLANG[2] headers and libraries.
You will also need CMake[3] >= 2.6.1 or GNU Make to build all of those
packages and subversion[4] and git[5] to get the source code.
[1] http://llvm.org
[2] http://clang.llvm.org
[3] http://cmake.org
[4] http://subversion.tigris.org
[5] http://git-scm.com
####Building
Building LLVM and CLANG you must:
- Check out the sources:
git clone http://root.cern.ch/git/llvm.git src
cd src
git checkout cling-patches
cd tools
git clone http://root.cern.ch/git/cling.git
git clone http://root.cern.ch/git/clang.git
cd clang
git checkout cling-patches
- Configure, build and install them, either using CMake:
cd ..
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/some/install/dir \
-DLLVM_TARGETS_TO_BUILD=CBackend\;CppBackend\;X86 \
-DCMAKE_BUILD_TYPE=Debug \
../src
make
make install
- or GNU Make (see ../src/configure --help for all options):
cd ..
mkdir build
cd build
../src/configure --prefix=/some/install/dir
make
make install
##USAGE
To get started run: /some/install/dir/bin/cling --help
or type
/some/install/dir/bin/cling
[cling]$ .help
##DEVELOPERS' CORNER:
We have doxygen documentation of cling's code at:
