Detailed Description

Functions in this group model LLVMValueRef instances that correspond to constants referring to scalar types.

For integer types, the LLVMTypeRef parameter should correspond to a llvm::IntegerType instance and the returned LLVMValueRef will correspond to a llvm::ConstantInt.

For floating point types, the LLVMTypeRef returned corresponds to a llvm::ConstantFP.

Function Documentation

◆ LLVMConstInt()

LLVMValueRef LLVMConstInt	(	LLVMTypeRef	IntTy,
		unsigned long long	N,
		LLVMBool	SignExtend
	)

Obtain a constant value for an integer type.

The returned value corresponds to a llvm::ConstantInt.

See also: llvm::ConstantInt::get()

Parameters

IntTy	Integer type to obtain value of.
N	The value the returned instance should refer to.
SignExtend	Whether to sign extend the produced value.

◆ LLVMConstIntGetSExtValue()

long long LLVMConstIntGetSExtValue ( LLVMValueRef ConstantVal )

Obtain the sign extended value for an integer constant value.

See also: llvm::ConstantInt::getSExtValue()

Definition at line 1515 of file Core.cpp.

◆ LLVMConstIntGetZExtValue()

unsigned long long LLVMConstIntGetZExtValue ( LLVMValueRef ConstantVal )

Obtain the zero extended value for an integer constant value.

See also: llvm::ConstantInt::getZExtValue()

Definition at line 1511 of file Core.cpp.

◆ LLVMConstIntOfArbitraryPrecision()

LLVMValueRef LLVMConstIntOfArbitraryPrecision	(	LLVMTypeRef	IntTy,
		unsigned	NumWords,
		const uint64_t	Words[]
	)

Obtain a constant value for an integer of arbitrary precision.

See also: llvm::ConstantInt::get()

Definition at line 1478 of file Core.cpp.

◆ LLVMConstIntOfString()

LLVMValueRef LLVMConstIntOfString	(	LLVMTypeRef	IntTy,
		const char *	Text,
		uint8_t	Radix
	)

Obtain a constant value for an integer parsed from a string.

A similar API, LLVMConstIntOfStringAndSize is also available. If the string's length is available, it is preferred to call that function instead.

See also: llvm::ConstantInt::get()

◆ LLVMConstIntOfStringAndSize()

LLVMValueRef LLVMConstIntOfStringAndSize	(	LLVMTypeRef	IntTy,
		const char *	Text,
		unsigned	SLen,
		uint8_t	Radix
	)

Obtain a constant value for an integer parsed from a string with specified length.

See also: llvm::ConstantInt::get()

◆ LLVMConstReal()

LLVMValueRef LLVMConstReal	(	LLVMTypeRef	RealTy,
		double	N
	)

Obtain a constant value referring to a double floating point value.

Definition at line 1498 of file Core.cpp.

References N, llvm::unwrap(), and llvm::wrap().

◆ LLVMConstRealGetDouble()

double LLVMConstRealGetDouble	(	LLVMValueRef	ConstantVal,
		LLVMBool *	losesInfo
	)

Obtain the double value for an floating point constant value.

losesInfo indicates if some precision was lost in the conversion.

◆ LLVMConstRealOfString()

LLVMValueRef LLVMConstRealOfString	(	LLVMTypeRef	RealTy,
		const char *	Text
	)

Obtain a constant for a floating point value parsed from a string.

A similar API, LLVMConstRealOfStringAndSize is also available. It should be used if the input string's length is known.

Definition at line 1502 of file Core.cpp.

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

◆ LLVMConstRealOfStringAndSize()

LLVMValueRef LLVMConstRealOfStringAndSize	(	LLVMTypeRef	RealTy,
		const char *	Text,
		unsigned	SLen
	)

Obtain a constant for a floating point value parsed from a string.
