Ramon de C Valle 65698ae9f3 Add LLVM KCFI support to the Rust compiler ... This commit adds LLVM Kernel Control Flow Integrity (KCFI) support to the Rust compiler. It initially provides forward-edge control flow protection for operating systems kernels for Rust-compiled code only by aggregating function pointers in groups identified by their return and parameter types. (See llvm/llvm-project@cff5bef.) Forward-edge control flow protection for C or C++ and Rust -compiled code "mixed binaries" (i.e., for when C or C++ and Rust -compiled code share the same virtual address space) will be provided in later work as part of this project by identifying C char and integer type uses at the time types are encoded (see Type metadata in the design document in the tracking issue #89653). LLVM KCFI can be enabled with -Zsanitizer=kcfi. Co-authored-by: bjorn3 <17426603+bjorn3@users.noreply.github.com>		2022-12-08 17:24:39 -08:00
