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

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()

Definition at line 527 of file Core.cpp.

References llvm::Constant::getAllOnesValue(), llvm::unwrap(), and llvm::wrap().

LLVMValueRef LLVMConstNull ( LLVMTypeRef Ty )

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

See also:: llvm::Constant::getNullValue()

Definition at line 523 of file Core.cpp.

References llvm::Constant::getNullValue(), llvm::unwrap(), and llvm::wrap().

LLVMValueRef LLVMConstPointerNull ( LLVMTypeRef Ty )

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

Definition at line 549 of file Core.cpp.

References llvm::ConstantPointerNull::get(), and llvm::wrap().

LLVMValueRef LLVMGetUndef ( LLVMTypeRef Ty )

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

See also:: llvm::UndefValue::get()

Definition at line 531 of file Core.cpp.

References llvm::UndefValue::get(), llvm::unwrap(), and llvm::wrap().

LLVMBool LLVMIsNull ( LLVMValueRef Val )

Determine whether a value instance is null.

See also:: llvm::Constant::isNullValue()

Definition at line 539 of file Core.cpp.

References llvm::CallingConv::C, and llvm::unwrap().
