Changes in directory llvm/lib/Target:
TargetMachine.cpp updated: 1.44 -> 1.45
---
Log message:
Added option -enable-finite-only-fp-math. When on, the codegen can assume that
FP arithmetic arguments and results are never NaNs or +=Infs. This includes
ignoring parity flag (PF) when checking for FP equality.
