DescriptionA miscompile flaw was found in LLVM. In certain conditions, the LR register can be overwritten without data being saved to the stack, which can lead to an exploitable error in the compiled code. This affects the ARM backend and can be demonstrated with Clang.A miscompile flaw was found in LLVM.
