inline

Match an 'ordered' floating point maximum function.

Floating point has one special value 'NaN'. Therefore, there is no total order. However, if we can ignore the 'NaN' value (for example, because of a 'no-nans-float-math' flag) a combination of a fcmp and select has 'maximum' semantics. In the presence of 'NaN' we have to preserve the original select(fcmp(ogt/ge, L, R), L, R) semantics matched by this predicate.

                    max(L, R)  iff L and R are not NaN

m_OrdFMax(L, R) = R iff L or R are NaN

template<typename LHS , typename RHS >
MaxMin_match<FCmpInst, LHS, RHS, ofmin_pred_ty> llvm::PatternMatch::m_OrdFMin ( const LHS &  L,
const RHS &  R 
)
inline

Match an 'ordered' floating point minimum function.

Floating point has one special value 'NaN'. Therefore, there is no total order. However, if we can ignore the 'NaN' value (for example, because of a 'no-nans-float-math' flag) a combination of a fcmp and select has 'minimum' semantics. In the presence of 'NaN' we have to preserve the original select(fcmp(olt/le, L, R), L, R) semantics matched by this predicate.
