Ivan Chinenov (Mar 26 2024 at 21:34): Ivan Chinenov (Mar 26 2024 at 21:34):If I'm remembering correctly, Cranelift doesn't have any builtin way to work with composites, so my question is, would that mean that the simplest way to deal with composites in function parameters is to pass by pointer?
Chris Fallin (Mar 26 2024 at 21:46):Yes, exactly. You'll want to define an ABI or convention of some sort in your compiler, but the gist of it is: put the storage somewhere (perhaps on a shadow stack?) and pass a pointer to it.
Ivan Chinenov (Mar 26 2024 at 22:00):What exactly do you mean by "shadow stack"?
Chris Fallin (Mar 26 2024 at 22:01):A mechanism to allocate storage via a bump-decrement pointer, sometimes used for stack-local storage; you can also use Cranelift stackslots for this, either way
