LLVMs Arm stack protection feature can be rendered ineffective

Overview The stack protection feature in LLVM's Arm backend can be rendered ineffective when the stack protector slot is re-allocated so that is appears after the local variables that it is meant to protect, leaving the function potentially vulnerable to a stack-based buffer overflow. Description...
