To Artifact [3c88a5e1a9]:

• File src/runtime/runtime-private.h — part of check-in [84a724dd4b] at 2013-12-06 00:52:26 on branch trunk — Add a fast path for objc_classname_to_class().

  This should improve the performance for the GCC ABI, as
  objc_classname_to_class() is used for all sorts of class lookups, e.g.
  objc_lookup_class().

  As this performance improvement needs RAM, it is only used after 128
  calls into objc_classname_to_class(), so that if the ObjFW ABI is used
  and the user does not call into objc_getClass() or similar in a loop, no
  memory is wasted.

  Runtime internal usage of objc_classname_to_class() does not use the
  fast path and does not count as a call into objc_classname_to_class().
  The reason for this is that if the runtime calls
  objc_classname_to_class(), it already has the lock and thus the
  performance gain would be small, but it would waste memory. (user: js, size: 5194) [annotate] [blame] [check-ins using]
