Perhaps. But it can be used under the hood by large-number support
routines, either libc "word×word->doubleword" or large integer
arithmetic such as is used by modern crypto. Even if there are only
two EMULU instructions in an executable, they can still make a

Well, modern compilers, because they attempt to be multi-target. Build
a VAX-target compiler, with no care for non-VAX targets, and it becomes

Only antique languages (like Lisp) with bignum support, or fringe
applications like cryptography.
