These routines do not require executable stacks. However, by default ELFish linkers may assume an executable stack on GNUish environments (and some non-GNU ones too!). The GNU extension to add a note to indicate a non-executable stack is honoured by these environments to mark the stack as non-executable (the compiler normally emits this directive on appropriate targets whenever possible). This allows normal builds from getting executable stacks due to linking to the compiler rt builtins. llvm-svn: 273500
