[LLVMdev] Dynamic Type Lookup ...

[Frank White]

Hello everyone, I would like to implement functionality something like the
following in my sample language.....

class A {
  Object attrA1
}

class B {
   int attrB1
   bool method methTestB ( .... )
}

main ()  {
  bool test
  Object a
  a = new Class A()
  a.attr1 = new Class B()

  a.attrB1 = 5
  test = a.methTestB(...)
}

I assume that I will need:

- some type of runtime lookup table to store the class structure of Class A
and B.
- some way of encoding and storing an object's attribute type information
- a means of retrieving this information at runtime so that in the event
that an object's attribute is itself an object, attributes from the latter
can be accessed as well.

I have looked at the LLVM API but didn't see any straightforward way to do
this.

Thanks in advance for any comments.
Frank.
