Subject: ARM: Use __STACK_LIMIT symbol for segmented stacks
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=b8c20fdb2b5cf219621ac7e1be8ce91246e83253;p=oota-llvm.git

ARM: Use __STACK_LIMIT symbol for segmented stacks

We cannot use STACK_LIMIT, as it is not reserved for the compiler
by the C spec.
