[llvm-commits] CVS: llvm/lib/VMCore/Type.cpp

[Chris Lattner]

Changes in directory llvm/lib/VMCore:

Type.cpp updated: 1.53 -> 1.54

Log message:

Don't bother doing an exhaustive recursive walk if we are at the limit of what 
we need to know anyway.  This reduces the 2002-07-08-HugePerformanceProblem.llx
down to 3.210u:0.010s, which is back in the acceptable range again
