We do already have Constant::isZeroValue(). There's also m_SpecificFP and m_AnyZero in PatternMatch.h. -Eli

Hi, I noticed that ConstantFP::get automatically returns the appropriately types Constant depending on the LLVM type passed in (i.e. if called with a vector, it returns a splat vector with the given constant). Is there any simple way to do the inverse of this function? i.e., given a llvm::Value, check whether it is either a scalar of the given constant value or a splat vector with the given
