20090310-3-scanbuild:
Add support for clang's scan-build utility to abuild. scan-build wraps the compiler and runs its own compiler on the same sources to do some static analysis on them. It adds an option "-sb" or "--scan-build" that creates a coreboot-builds/$target-scanbuild directory for every $target, containing the output of scan-build, which is a HTML documentation on its results. Be aware, that scanbuild significantly increases build time: A board that takes 6-7 seconds normally requires 60 seconds with that option enabled on my test system. The patch also moves the stack-protector option down a bit, so it applies to crosscompiled targets, too (which overwrote the compiler settings before) Signed-off-by: Patrick Georgi <patrick.georgi@coresystems.de> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@3996 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
