It's something that the compiler would handle, but can still moderately influence programming decisions, i.e. you can have a lot more temporary variables before things start slowing down due to spill stores/loads (esp. in, say, a loop with function calls, as more registers also means more non-volatile registers (i.e. those that are guaranteed to not change across function calls)). But, yes, very limited impact even then.
It's certainly something I would take into consideration when making a (language) runtime, but probably not at all during all but the most performance sensitive of applications. Certainly a difference, but far lower level than what most applications require
Yep. Unfortunately I am one to be making language runtimes :)
It's just the potentially most significant thing I could come up with at first. Though perhaps RVV not being in rva20/rv64gc is more significant.
Looks like an APL project? That's really cool!
