[llvm-commits] CVS: llvm-java/lib/Compiler/VMClass.cpp

Changes in directory llvm-java/lib/Compiler:

VMClass.cpp updated: 1.46 -> 1.47
---
Log message:

Reverse the array of superclasses in the type information block. This
makes instanceof a bit faster since we don't need to subtract the two
depths to check if a class is a subclass of another.

This was pointed out by Dinakar at the presentation today. Thanks Dinakar :-)
