Previously we had the following approach: - classes that implemented interfaces had an interface table - classes that didn't implement an interface, but inherited from a class that did had a Nil entry - classes that didn't implement any interface (including their parents) had a reference to FPC_EMPTYINTF (this was to optimize lookups) Now the approach is as follows: - classes that implement an interface or have a parent that implements an interface have an interface table; if the class itself doesn't implement an interface then the count will be 0 - classes that don't implement an interface at all (neither them nor their parents) have a Nil interface table This way FPC_EMPTYINTF can be removed without sacrificing at least the optimization for classes without any interface. For classes that have parents with interfaces there will be a small speed penalty due to an additional lookup for the counter. git-svn-id: trunk@34087 - |
