Changes in directory llvm/lib/Transforms/IPO:
LowerSetJmp.cpp updated: 1.27 -> 1.28
SimplifyLibCalls.cpp updated: 1.54 -> 1.55
---
Log message:
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.
