class ConstantExpr

Declaration

class ConstantExpr : public Constant { /* full declaration omitted */ };

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.

Declared at: llvm/include/llvm/IR/Constants.h:1125

Parameters

unsigned int Opcode

llvm::Constant* C1

unsigned int Flags = 0

llvm::Type* OnlyIfReducedTy = nullptr

see \a getWithOperands() docs.

¶static llvm::Constant* getAShr(
    llvm::Constant* C1,
    llvm::Constant* C2,
    bool isExact = false)

Declared at: llvm/include/llvm/IR/Constants.h:953

Parameters

llvm::Constant* C1

llvm::Constant* C2

bool isExact = false

¶static llvm::Constant* getAdd(llvm::Constant* C1,
                              llvm::Constant* C2,
                              bool HasNUW = false,
                              bool HasNSW = false)

Declared at: llvm/include/llvm/IR/Constants.h:932

Parameters

llvm::Constant* C1

llvm::Constant* C2

bool HasNUW = false

bool HasNSW = false

¶static llvm::Constant* getAddrSpaceCast(
    llvm::Constant* C,
    llvm::Type* Ty,
    bool OnlyIfReduced = false)

Declared at: llvm/include/llvm/IR/Constants.h:971

Parameters

llvm::Constant* C

llvm::Type* Ty

bool OnlyIfReduced = false

¶static llvm::Constant* getAlignOf(llvm::Type* Ty)

Description

getAlignOf constant expr - computes the alignment of a type in a target independent way (Note: the return type is an i64).

Declared at: llvm/include/llvm/IR/Constants.h:911

Parameters

llvm::Type* Ty

¶static llvm::Constant* getAnd(llvm::Constant* C1,
                              llvm::Constant* C2)

Declared at: llvm/include/llvm/IR/Constants.h:947

Parameters

llvm::Constant* C1

llvm::Constant* C2

¶llvm::Instruction* getAsInstruction() const

Description

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.

Declared at: llvm/include/llvm/IR/Constants.h:1254

¶static llvm::Constant* getBinOpAbsorber(
    unsigned int Opcode,
    llvm::Type* Ty)

Description

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.

Declared at: llvm/include/llvm/IR/Constants.h:1039

Parameters

unsigned int Opcode

llvm::Type* Ty

¶static llvm::Constant* getBinOpIdentity(
    unsigned int Opcode,
    llvm::Type* Ty,
    bool AllowRHSConstant = false)

Description

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.

Declared at: llvm/include/llvm/IR/Constants.h:1032

Parameters

unsigned int Opcode

llvm::Type* Ty

bool AllowRHSConstant = false
