* Android support for SafeStack.Evgeniy Stepanov2015-09-231-0/+38
Add two new ways of accessing the unsafe stack pointer: * At a fixed offset from the thread TLS base. This is very similar to StackProtector cookies, but we plan to extend it to other backends (ARM in particular) soon. Bionic-side implementation here: https://android-review.googlesource.com/170988. * Via a function call, as a fallback for platforms that provide neither a fixed TLS slot, nor a reasonable TLS implementation (i.e. not emutls). llvm-svn: 248357
