Detailed Description

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.

getAsInstruction()

Instruction * ConstantExpr::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.

getBinOpAbsorber()

Constant * ConstantExpr::getBinOpAbsorber ( unsigned  Opcode, Type *  Ty  )

static

Return the absorbing element for the given binary operation, i.e.

a constant C such that X op C = C and C op X = C for every X. For example, this returns zero for integer multiplication. It returns null if the operator doesn't have an absorbing element.

getBinOpIdentity()

Constant * ConstantExpr::getBinOpIdentity ( unsigned  Opcode, Type *  Ty, bool  AllowRHSConstant = false  )

static

Return the identity constant for a binary opcode.

The identity constant C is defined as X op C = X and C op X = X for every X when the binary operation is commutative. If the binop is not commutative, callers can acquire the operand 1 identity constant by setting AllowRHSConstant to true. For example, any shift has a zero identity constant for operand 1: X shift 0 = X. Return nullptr if the operator does not have an identity constant.
