[llvm-commits] CVS: llvm/lib/Transforms/Utils/Local.cpp

[Brian Gaeke]

Changes in directory llvm/lib/Transforms/Utils:

Local.cpp updated: 1.26 -> 1.27

---
Log message:

Quick hack to get this file compiling again on Mac OS X.  The right thing to do
is write an autoconf macro that checks whether __isnan or isnan actually works
**using the C++ compiler after #include <cmath>**, instead of doing it the easy
way with AC_CHECK_FUNCS().
