Jeff Cohen a38c737e85 When a function takes a variable number of pointer arguments, with a zero ... pointer marking the end of the list, the zero *must* be cast to the pointer type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will not extend the zero to 64 bits, thus allowing the upper 32 bits to be random junk. The new END_WITH_NULL macro may be used to annotate a such a function so that GCC (version 4 or newer) will detect the use of un-casted zero at compile time. llvm-svn: 23888		2005-10-23 04:37:20 +00:00
