[llvm-commits] CVS: llvm/lib/Transforms/IPO/LoopExtractor.cpp

[Chris Lattner]

Changes in directory llvm/lib/Transforms/IPO:

LoopExtractor.cpp updated: 1.10 -> 1.11

---
Log message:

Change the ExitBlocks list from being explicitly contained in the Loop
structure to being dynamically computed on demand.  This makes updating
loop information MUCH easier.

Diffs of the changes:  (+4 -2)
