Adds support for LLVM [SafeStack] which provides backward edge control flow protection by separating the stack into two parts: data which is only accessed in provable safe ways is allocated on the normal stack (the "safe stack") and all other data is placed in a separate allocation (the "unsafe stack"). SafeStack support is enabled by passing `-Zsanitizer=safestack`. [SafeStack]: https://clang.llvm.org/docs/SafeStack.html |

This directory currently contains some LLVM support code. This will generally be sent upstream to LLVM in time; for now it lives here. NOTE: the LLVM C++ ABI is subject to between-version breakage and must *never* be exposed to Rust. To allow for easy auditing of that, all Rust-exposed types must be typedef-ed as "LLVMXyz", or "LLVMRustXyz" if they were defined here. Functions that return a failure status and leave the error in the LLVM last error should return an LLVMRustResult rather than an int or anything to avoid confusion. When translating enums, add a single `Other` variant as the first one to allow for new variants to be added. It should abort when used as an input. All other types must not be typedef-ed as such.
