Detailed Description

This section contains APIs for interacting with LLVMValueRef that correspond to llvm::Constant instances.

These functions will work for any LLVMValueRef in the llvm::Constant class hierarchy.

Function Documentation

LLVMConstAllOnes()

LLVMValueRef LLVMConstAllOnes

(

LLVMTypeRef

Ty

)

Obtain a constant value referring to the instance of a type consisting of all ones.

This is only valid for integer types.

See also

llvm::Constant::getAllOnesValue()

LLVMConstNull()

LLVMValueRef LLVMConstNull

(

LLVMTypeRef

Ty

)

Obtain a constant value referring to the null instance of a type.

See also

llvm::Constant::getNullValue()

LLVMConstPointerNull()

LLVMValueRef LLVMConstPointerNull

(

LLVMTypeRef

Ty

)

Obtain a constant that is a constant pointer pointing to NULL for a specified type.

LLVMGetPoison()

LLVMValueRef LLVMGetPoison

(

LLVMTypeRef

Ty

)

Obtain a constant value referring to a poison value of a type.

See also

llvm::PoisonValue::get()

LLVMGetUndef()

LLVMValueRef LLVMGetUndef

(

LLVMTypeRef

Ty

)

Obtain a constant value referring to an undefined value of a type.

See also

llvm::UndefValue::get()

LLVMIsNull()

LLVMBool LLVMIsNull

(

LLVMValueRef

Val

)

Determine whether a value instance is null.
