getNZCVToSatisfyCondCode()

static unsigned llvm::AArch64CC::getNZCVToSatisfyCondCode ( CondCode  Code )

inlinestatic

Given a condition code, return NZCV flags that would satisfy that condition.

The flag bits are in the format expected by the ccmp instructions. Note that many different flag settings can satisfy a given condition code, this function just returns one of them.
