In comparison to
memory
andatomic
, theplatform
module does not automatically infer the definition of the provided functionality from the chosen backend. Instead, the dispatching logic as well as all backend-specific definitions are thrown together in preprocessor if clauses.Move these definitions into backend
platform
modules and add an automatic dispatch mechanism similar to the one used in thememory
andatomic
modules. This simplifies the introduction of new backends in the future and exposes the requirements to backends in a more complete manner. In addition to this change, the compiler detection has been moved to a newcompiler
module which is implicitly included byplatform
for backwards compatibility.
