¶llvm::hash_code hash_value(
    const llvm::detail::IEEEFloat& Arg)

Description

Overload to compute a hash code for an APFloat value. Note that the use of hash codes for floating point values is in general frought with peril. Equality is hard to define for these values. For example, should negative and positive zero hash to different codes? Are they equal or not? This hash value implementation specifically emphasizes producing different codes for different inputs in order to be used in canonicalization and memoization. As such, equality is bitwiseIsEqual, and 0 != -0.
