This patch is what I needed to compile coreboot with LLVM.
- call va_* directly if coreboot is running on GCC so we don't need to maintain hacks to get to stdarg.h - only define LIBGCC_FILE_NAME if it's an absolute path. GCC and LLVM just print "libgcc.a" if the file is not there. Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Acked-by: Ronald G. Minnich <rminnich@gmail.com> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5215 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
