Sami Tolvanen cacd3e73d7 Add generic KCFI operand bundle lowering ... The KCFI sanitizer emits "kcfi" operand bundles to indirect call instructions, which the LLVM back-end lowers into an architecture-specific type check with a known machine instruction sequence. Currently, KCFI operand bundle lowering is supported only on 64-bit X86 and AArch64 architectures. As a lightweight forward-edge CFI implementation that doesn't require LTO is also useful for non-Linux low-level targets on other machine architectures, add a generic KCFI operand bundle lowering pass that's only used when back-end lowering support is not available and allows -fsanitize=kcfi to be enabled in Clang on all architectures. This relands commit eb2a57ebc7 with fixes. Reviewed By: nickdesaulniers, MaskRay Differential Revision: https://reviews.llvm.org/D135411		2022-11-22 23:01:18 +00:00
