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

[Reid Spencer]

Changes in directory llvm/lib/Transforms/IPO:

SimplifyLibCalls.cpp updated: 1.56 -> 1.57
---
Log message:

For PR696: http://llvm.cs.uiuc.edu/PR696 :
Don't do floor->floorf conversion if floorf is not available. This checks
the compiler's host, not its target, which is incorrect for cross-compilers
Not sure that's important as we don't build many cross-compilers.
