bors 93ffde6f04 Auto merge of #98208 - ivanloz:master, r=nagisa ... Add support for LLVM ShadowCallStack. LLVMs ShadowCallStack provides backward edge control flow integrity protection by using a separate shadow stack to store and retrieve a function's return address. LLVM currently only supports this for AArch64 targets. The x18 register is used to hold the pointer to the shadow stack, and therefore this only works on ABIs which reserve x18. Further details are available in the [LLVM ShadowCallStack](https://clang.llvm.org/docs/ShadowCallStack.html) docs. # Usage `-Zsanitizer=shadow-call-stack` # Comments/Caveats * Currently only enabled for the aarch64-linux-android target * Requires the platform to define a runtime to initialize the shadow stack, see the [LLVM docs](https://clang.llvm.org/docs/ShadowCallStack.html) for more detail.		2022-07-23 20:01:07 +00:00
