<p>Note that you will need about 1-3 GB of space for a full LLVM build in Debug
mode, depending on the system (because of all the debug info), and the libraries
appear in more than one of the tools that get linked, so there is some
duplication. If you do not need many of the tools and you are space-conscious,
you can disable them individually in <tt>llvm/tools/Makefile</tt>. The Release
build requires considerably less space.</p>
<p>The LLVM suite <i>may</i> compile on other platforms, but it is not
guaranteed to do so. If compilation is successful, the LLVM utilities should be
able to assemble, disassemble, analyze, and optimize LLVM bytecode. Code
