Description

It would be nice to make the compiler API as consistent as possible between targets and to eliminate a failure case in the space safety theorem. I expect that this would be tedious but not technically challenging. Doing it at the basis level might be a good test case for unboxing optimizations; doing it in wordLang would be more work with no access to the translator, but could produce a better result with fewer innovations.

Contributor guide

Research direction
Investigate the current soft float implementation in CakeML's basis and wordLang. Trace how the compiler handles floating point operations on targets without hardware float. Determine the best approach to implement soft float fallback to ensure API consistency.
