b1fcb596fe
This patch adds support for the compiler-rt (CLANG runtime) library. It builds a set of static libraries and installs them into the CLANG/LLVM toolchain resource folder. These libraries can then be used by developers in the SDK for building target applications for analysis. What is fuzzing and why libfuzzer? https://www.moritz.systems/blog/an-introduction-to-llvm-libfuzzer/ The compiler-rt fuzzer and address sanitizer tools require additional LLVM binary tools installed to allow stack trace decoding actively during executable analysis. This patch conditionally enables these tools. https://github.com/google/sanitizers/wiki/AddressSanitizerCallStack Signed-off-by: Matt Weber <matthew.weber@rockwellcollins.com> Signed-off-by: James Hilliard <james.hilliard1@gmail.com> Cc: Romain Naour <romain.naour@smile.fr> Cc: Ricardo Martincoski <ricardo.martincoski@gmail.com> Cc: Valentin Korenblit <valentinkorenblit@gmail.com> Cc: Michael Drake <michael.drake@codethink.co.uk> Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>
