%description
    Low-Level Virtual Machine (LLVM) is a compilation strategy designed
    to enable effective program optimization across the entire lifetime
    of a program. LLVM supports effective optimization at compile time,
    link-time (particularly interprocedural), run-time and offline
    (i.e., after software is installed), while remaining transparent
    to developers and maintaining compatibility with existing build
    scripts. LLVM is a virtual instruction set. LLVM is a low-level
    object code representation that uses simple RISC-like instructions.
    LLVM provides a link-time optimization framework with a growing set
    of global and interprocedural analyses and transformations, static
    back-ends for the X86, X86-64, PowerPC 32/64, ARM, Thumb, IA-64,
    Alpha and SPARC architectures, a back-end which emits portable C
    code, and a Just-In-Time compiler for X86, X86-64, PowerPC 32/64
    processors.
