---+!! LLVM/Clang Static Analyzer

%TOC%

---++ Instructions (Linux)

   * Follow the instructions in HowToCompile

   * Build LLVM and Clang: http://clang.llvm.org/get_started.html

   * Copy llvm/Debug/bin/clang-cc and the following files to the RB build diretory.<br/>
    "llvm/tools/clang/utils": ccc-analyzer, scan-build, scanview.css, sortable.js

   * Because Clang doesn't seem to handle ARM ASM, uncomment all ASM parts in:<br/>
    firmware/target/arm/system-arm.h<br/>
    firmware/target/arm/system-target.h<br/>
    There are many more places with ASM which stop the parser,<br/>
    but these 2 files get included very often..<br/>

   * Go to the build directory.

   * Add the compiler to the path:<br/>
    "export PATH=$PATH:/usr/local/arm-elf/bin/"

   * Configure (select sansa e200):<br/>
    "../tools/configure"

   * Make the dependencies (because Clang can't do that):<br/>
    "make dep"

   * Comment out "export CC=.." in the Makefile (build dir)

   * Add the following directory to the "C include path" (for Clang)<br/>
    "export C_INCLUDE_PATH=/usr/local/arm-elf/lib/gcc/arm-elf/4.0.3/include/"

   * Start the compiler:<br/>
    "./scan-build --use-cc=/usr/local/arm-elf/bin/arm-elf-gcc make"<br/>
    Report gets saved in /tmp/scan-build-xxx_something

   * [[%ATTACHURL%/scan-build-2009-03-31-1.tar.bz2][scan-build-2009-03-31-1.tar.bz2]]: A report for a Sansa e200 build.
