Hello everyone, After reading the nice blog post about _ExtInt, I was wondering whether operations on i128/i256 and more generally on integer types in LLVM are guaranteed to be constant time or not. For instance, for now, the x86 & aarch64 backend generate constant time code for additions on i256 integers (see https://godbolt.org/z/xMfkqz & https://godbolt.org/z/jbkSpe), but is there
