[llvm-commits] CVS: llvm/lib/Analysis/IPA/Andersens.cpp

[Chris Lattner]

Changes in directory llvm/lib/Analysis/IPA:

Andersens.cpp updated: 1.18 -> 1.19
---
Log message:

Fix a major problem with global variable initializers.  This could cause
us to have stuff pointing to the null pointer, which makes no sense
(the null ptr is an ssa value, not the null object)
