Public Member Functions
	BasicLoadAndStorePromoter (ArrayRef< const Instruction * > Insts, SSAUpdater &S, Type *ZeroType)
bool	shouldDelete (Instruction *I) const override
	Return false if a sub-class wants to keep one of the loads/stores after the SSA construction.
Value *	getValueToUseForAlloca (Instruction *I) const override
	Return the value to use for the point in the code that the alloca is positioned.

◆ getValueToUseForAlloca()

Value * BasicLoadAndStorePromoter::getValueToUseForAlloca ( Instruction * AI) const	inlineoverridevirtual

Return the value to use for the point in the code that the alloca is positioned.

This will only be used if an Alloca is included in Insts, otherwise the value of a uninitialized load will be assumed to be poison.
