Read the documentation. +2. Seriously, read the documentation. +3. Remember that you were warned twice about reading the documentation. +4. Get the Source Code + + * With the distributed files: + + 1. ``cd <where-you-want-llvm-to-live>`` + 2. ``gunzip --stdout llvm-VERSION.tar.gz | tar -xvf -`` + (*or use WinZip*) + 3. ``cd llvm`` + + * With anonymous Subversion access: + + 1. ``cd <where-you-want-llvm-to-live>`` + 2. ``svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm`` + 3. ``cd llvm`` + +5.

Another important option is ``LLVM_TARGETS_TO_BUILD``, + which controls the LLVM target architectures that are included on the + build. + * See the `LLVM CMake guide <CMake.html>`_ for detailed information about + how to configure the LLVM build. + +6. Start Visual Studio + + * In the directory you created the project files will have an ``llvm.sln`` + file, just double-click on that to open Visual Studio. + +7. Build the LLVM Suite: + + * The projects may still be built individually, but to build them all do + not just select all of them in batch build (as some are meant as + configuration projects), but rather select and build just the + ``ALL_BUILD`` project to build everything, or the ``INSTALL`` project, + which first builds the ``ALL_BUILD`` project, then installs the LLVM + headers, libs, and other useful things to the directory set by the + ``CMAKE_INSTALL_PREFIX`` setting when you first configured CMake. + * The Fibonacci project is a sample program that uses the JIT.

Test LLVM on Visual Studio: + + * If ``%PATH%`` does not contain GnuWin32, you may specify + ``LLVM_LIT_TOOLS_DIR`` on CMake for the path to GnuWin32. + * You can run LLVM tests by merely building the project "check". The test + results will be shown in the VS output window. + +.. FIXME: Is it up-to-date? + +9. Test LLVM: + + * The LLVM tests can be run by changing directory to the llvm source + directory and running: + + .. code-block:: bat + + C:\..\llvm> llvm-lit test + + Note that quite a few of these test will fail. + + A specific test or test directory can be run with: + + .. code-block:: bat + + C:\..\llvm> llvm-lit test/path/to/test + + +An Example Using the LLVM Tool Chain +==================================== + +1. First, create a simple C file, name it '``hello.c``': + + .. code-block:: c + + #include <stdio.h> + int main() { + printf("hello world\n"); + return 0; + } + +2. Next, compile the C file into a LLVM bitcode file: + + .. code-block:: bat + + C:\..> clang -c hello.c -emit-llvm -o hello.bc + + This will create the result file ``hello.bc`` which is the LLVM bitcode + that corresponds the the compiled program and the library facilities that + it required. You can execute this file directly using ``lli`` tool, + compile it to native assembly with the ``llc``, optimize or analyze it + further with the ``opt`` tool, etc. + + Alternatively you can directly output an executable with clang with: + + .. code-block:: bat + + C:\..> clang hello.c -o hello.exe + + The ``-o hello.exe`` is required because clang currently outputs ``a.out`` + when neither ``-o`` nor ``-c`` are given. + +3. Run the program using the just-in-time compiler: + + .. code-block:: bat + + C:\..> lli hello.bc + +4. Use the ``llvm-dis`` utility to take a look at the LLVM assembly code: + + .. code-block:: bat + + C:\..> llvm-dis < hello.bc | more + +5. Compile the program to object code using the LLC code generator: + + .. code-block:: bat + + C:\..> llc -filetype=obj hello.bc + +6. Link to binary using Microsoft link: + + .. code-block:: bat + + C:\..> link hello.obj -defaultlib:libcmt + +7. Execute the native code program: + + .. code-block:: bat + + C:\..> hello.exe + + +Common Problems +=============== +If you are having problems building or using LLVM, or if you have any other +general questions about LLVM, please consult the `Frequently Asked Questions +<FAQ.html>`_ page. + + +Links +===== +This document is just an **introduction** to how to use LLVM to do some simple +things... there are many more interesting and complicated things that you can +do that aren't documented here (but we'll gladly accept a patch if you want to +write something up!).
