Detailed Description

Function Documentation

LLVMCountParamTypes()

LLVM_C_ABI unsigned LLVMCountParamTypes

(

LLVMTypeRef

FunctionTy

)

Obtain the number of parameters this function accepts.

Definition at line 778 of file Core.cpp.

References llvm::unwrap().

LLVMFunctionType()

LLVM_C_ABI LLVMTypeRef LLVMFunctionType	(	LLVMTypeRef	ReturnType,
		LLVMTypeRef *	ParamTypes,
		unsigned	ParamCount,
		LLVMBool	IsVarArg )

Obtain a function type consisting of a specified signature.

The function is defined as a tuple of a return Type, a list of parameter types, and whether the function is variadic.

Definition at line 763 of file Core.cpp.

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

LLVMGetParamTypes()

LLVM_C_ABI void LLVMGetParamTypes	(	LLVMTypeRef	FunctionTy,
		LLVMTypeRef *	Dest )

Obtain the types of a function's parameters.

The Dest parameter should point to a pre-allocated array of LLVMTypeRef at least LLVMCountParamTypes() large. On return, the first LLVMCountParamTypes() entries in the array will be populated with LLVMTypeRef instances.

Parameters

FunctionTy	The function type to operate on.
Dest	Memory address of an array to be filled with result.
