What's the point of this when you can compile between ISAs using a build tool and source? When would you need to cross compile a binary after building?
It's for closed source software obviously.
Isn't going all that AI tech going to make automated decompilation trivial? Re-compiling would not need illustrative variable names...
That is basically what this does, but more reliably.
Because you don't have the source or because you can't configure the cross-compiler
I guess I'm confused about the context you'd be in that situation.
E.g. when you have a proprietary program that is only available on x86, but you want to run it on ARM.
Easy to explain: The idiot project manager skipped to set up source control, and the sources have been lost.
Most software most people run is closed source and doesn't have an arm version. Isn't this the usual situation? Aunt Flo isn't recompiling her tax filing software for arm. She just runs it, and it works because the arm laptop she has came with this built in.
I'm not talking about closed source software (heaven forfend!) but maybe you don't have network access, or you don't know what version you have or something. Sometimes even the best of us end up with binaries of unknown provenance that still must run.
