<pre>Hi,
this is more a feature proposal than a bug report.
For WASM, we have
__attribute__((import_name(name)))
__attribute__((export_name(name)))
This is static and not yet really suitable for generic types and functions.
Can this be extended, e.g. in the following manner:
__attribute__((import_name("importedfunction1<T>")))
Where T gets replaced by the generic argument type name.
In order to be able to address unmangled or language independent type names,
another addition may be needed:
We would need to be able to decorate types/classes with another attribute, e.g.
__attribute__((wasm_type_name("MyClass1NameAttribute"))) class MyClass1 { ...
};
So we can get finally to resolve
__attribute__((import_name("importedfunction1<T>"))) generic_type_function1()
{}
into a wasm import name importedfunction1<MyClass1NameAttribute>.
This can be very useful if the executing VM is aware of the generics the wasm
module is implementing.
Many Thanks,
Sascha</pre>
