Detailed Description

ConstantExpr - a constant value that is initialized with an expression using other constant values.

This class uses the standard Instruction opcodes to define the various constant expressions. The Opcode field for the ConstantExpr class is maintained in the Value::SubclassData field.

void ConstantExpr::destroyConstant

(

)

[override, virtual]

destroyConstant - Called if some element of this constant is no longer valid. At this point only other constants may be on the use_list for this constant. Any constants on our Use list must also be destroy'd. The implementation must be sure to remove the constant from the list of available cached constants. Implementations should call destroyConstantImpl as the last thing they do, to destroy all users and delete this.

Instruction * ConstantExpr::getAsInstruction

(

)

getAsInstruction - Returns an Instruction which implements the same operation as this ConstantExpr. The instruction is not linked to any basic block.

A better approach to this could be to have a constructor for Instruction which would take a ConstantExpr parameter, but that would have spread implementation details of ConstantExpr outside of Constants.cpp, which would make it harder to remove ConstantExprs altogether.

const

Return true if this is a getelementptr expression and all the index operands are compile-time known integers within the corresponding notional static array extents. Note that this is not equivalant to, a subset of, or a superset of the "inbounds" property.

void ConstantExpr::replaceUsesOfWithOnConstant	(	Value *	,
		Value *	,
		Use *
	)		[override, virtual]

replaceUsesOfWithOnConstant - This method is a special form of User::replaceUsesOfWith (which does not work on constants) that does work on constants. Basically this method goes through the trouble of building a new constant that is equivalent to the current one, with all uses of From replaced with uses of To. After this construction is completed, all of the users of 'this' are replaced to use the new constant, and then 'this' is deleted. In general, you should not call this method, instead, use Value::replaceAllUsesWith, which automatically dispatches to this method as needed.

Reimplemented from llvm::Constant.
