◆ get() [2/4]

If Ty is a vector type, return a Constant with a splat of the given value.

Otherwise return a ConstantFP for the given value.

This returns a ConstantFP, or a vector containing a splat of a ConstantFP, for the specified value in the specified type.

This should only be used for simple constant values like 2.0/1.0 etc, that are known-valid both as host double and as the target format.

◆ isExactlyValue() [1/2]

bool ConstantFP::isExactlyValue ( const APFloat V) const

We don't rely on operator== working on double values, as it returns true for things that are clearly not equal, like -0.0 and 0.0.

As such, this method can be used to do an exact bit-for-bit comparison of two floating point values. The version with a double operand is retained because it's so convenient to write isExactlyValue(2.0), but please use it only for simple constants.
