The startup code in csu/, and the brk and sbrk functions are needed very early in initialization of a statically-linked program, before the stack guard is initialized; TLS initialization also uses memcpy, which cannot overrun its own stack. Mark all of these as -fno-stack-protector. We also finally introduce @libc_cv_ssp@ and @no_stack_protector@, both substituted by the configury changes made earlier, to detect the case when -fno-stack-protector is supported by the compiler, and unconditionally pass it in when this is the case, whether or not --enable-stack-protector is passed to configure. (This means that it'll even work when the compiler's been hacked to pass -fstack-protector by default, unless the hackage is so broken that it does so in a way that is impossible to override.) |
