I am looking for a way to obtain the class hierarchy of a program in
MacPas mode (where there are no published properties). TObject has
ClassParent, so a list of Class types would be sufficient, I think. I
can't find however a routine in the RTL to obtain such a list.
There is no such routine in the RTL, to my knowledge.
Can I add it ? I guess a low-level pointer to a list of VMT's would be
sufficient to implement it ?
Problem is: it breaks smartlinking.
Yes, I understand that. I looked at the assembly generated for a simple test
program and there are separate al_globals entries for each vmt and separate
al_rtti entries for the vmt rtti. I asssume the very reason for the separate
entries is smart linking.
Hm, I guess I can look at the data section of the executable but it would be
highly dependant of the executable binary format.
Is it possible to produce a separate data section/entry that refers to all
al_globals and/or all al_rtti entries without breaking smart-linking ?
Maybe when doing whole-program optimization as implemented by Jonas.
I guess the WPO could be extended to generate the tree you want.
But under 'normal' compilation, I don't think it is possible to do as you
ask without breaking the smartlinking stuff; the tree would of necessity
contain all declared classes of all loaded units.
Michael.
