LLVM/Clang Static Analyzer

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.
  "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:
  firmware/target/arm/system-arm.h
  firmware/target/arm/system-target.h
  There are many more places with ASM which stop the parser,
  but these 2 files get included very often..
  

• Go to the build directory.

• Add the compiler to the path:
  "export PATH=$PATH:/usr/local/arm-elf/bin/"

• Configure (select sansa e200):
  "../tools/configure"

• Make the dependencies (because Clang can't do that):
  "make dep"

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

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

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

• scan-build-2009-03-31-1.tar.bz2: A report for a Sansa e200 build.
