[llvm-commits] CVS: llvm/lib/Analysis/DataStructure/TopDownClosure.cpp

[Chris Lattner]

Changes in directory llvm/lib/Analysis/DataStructure:

TopDownClosure.cpp updated: 1.62 -> 1.63

---
Log message:

In the TD pass, don't iterate over the scalar map to find the globals, iterate over
the globals directly.  This doesn't save any substantial time, however, because the
globals graph only contains globals!

Diffs of the changes:  (+2 -3)
