Does this not involve transpilation? I guess I was grouping that in under dynamic recompilation and AOT techniques.
Regardless, I don't think that there's a benefit from defining emulation from an implementation rather than an empirical perspective. If it runs a chunk of code as if it were in a different environment, I'm kind of ok to call it an emulator. To the sibling's point, a polyfill would also fit as an emulation layer here.
Not necessarily. It could just rewrite the outer portion to be an ELF loader that then calls into a runtime that actually shims the syscalls for example. I don't think WINE does exactly this but it's not really transpiling either.
