I think you mean "non-transformative", although in this context I can see there's a bit of an ambiguity in how people would use the word "transform" to mean one thing w.r.t copyright and the "opposite" for code (really, orthogonal, but boolean evaluation would yield the opposite true/false).

In copyright, "transformative" refers to modifying or adapting a copyrighted work in a way that creates a new and original expression; resulting in a new work with a different purpose or meaning.

In terms of code, you'd "just be transforming" the assembly code to a systems language of your choice.
