llvm::PatternMatch::m_OrdOrUnordFMin

Match an ordered or unordered floating‐point minimum.

Synopsis

Declared in <llvm/IR/PatternMatch.h>

template<
    typename LHS,
    typename RHS>
match_combine_or<FMaxMin_match<LHS, RHS, ofmin_pred_ty>, FMaxMin_match<LHS, RHS, ufmin_pred_ty>>
m_OrdOrUnordFMin(
    LHS const& L,
    RHS const& R);

Description

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.

Return Value

A matcher for an ordered or unordered floating‐point minimum.

Parameters

Name

Description

Left‐hand matcher.

Right‐hand matcher.
