Indeed.  But a compiler is also free to not do so.

Writing machine-dependent code in something other than assembler is
dependent on having a compiler that produces the desired result.  A
compiler that doesn't, whether because it's broken or because it takes
advantage of latitude in the languageg spec, simply is not suitable for
that use.
