Method CreateFunction

CreateFunction(String, IFunctionType)

Gets an existing function with the specified signature to the module or creates a new one if it doesn't exist

Declaration

public IrFunction CreateFunction(string name, IFunctionType signature)

Parameters

String	name	Name of the function to add
IFunctionType	signature	Signature of the function

Returns

IrFunction

IrFunctionmatching the specified signature and name

Remarks

If a matching function already exists it is returned, and therefore the returned IrFunction may have a body and additional attributes. If a function of the same name exists with a different signature an exception is thrown as LLVM does not perform any function overloading.

CreateFunction(DIScope, String, String, DIFile, UInt32, DebugFunctionType, Boolean, Boolean, UInt32, DebugInfoFlags, Boolean)

Creates a Function definition with Debug information

Declaration

public IrFunction CreateFunction(DIScope scope, string name, string linkageName, DIFile file, uint line, DebugFunctionType signature, bool isLocalToUnit, bool isDefinition, uint scopeLine, DebugInfoFlags debugFlags, bool isOptimized)

Parameters

DIScope	scope	Containing scope for the function
String	name	Name of the function in source language form
String	linkageName	Mangled linker visible name of the function (may be same as name if mangling not required by source language
DIFile	file	File containing the function definition
UInt32	line	Line number of the function definition
DebugFunctionType	signature	LLVM Function type for the signature of the function
Boolean	isLocalToUnit	Flag to indicate if this function is local to the compilation unit
Boolean	isDefinition	Flag to indicate if this is a definition
UInt32	scopeLine	First line of the function's outermost scope, this may not be the same as the first line of the function definition due to source formatting
DebugInfoFlags	debugFlags	Additional flags describing this function
Boolean	isOptimized	Flag to indicate if this function is optimized

Returns

IrFunction

Function described by the arguments

CreateFunction(String, Boolean, IDebugType<ITypeRef, DIType>, IEnumerable<IDebugType<ITypeRef, DIType>>)

Creates a function

Declaration

public IrFunction CreateFunction(string name, bool isVarArg, IDebugType<ITypeRef, DIType> returnType, IEnumerable<IDebugType<ITypeRef, DIType>> argumentTypes)

Parameters

String	name	Name of the function
Boolean	isVarArg	Flag indicating if the function supports a variadic argument list
IDebugType<ITypeRef, DIType>	returnType	Return type of the function
IEnumerable<IDebugType<ITypeRef, DIType>>	argumentTypes	Arguments for the function

Returns

IrFunction

Function, matching the signature specified. This may be a previously declared or defined function or a new function if none matching the name and signature is already present.

CreateFunction(String, Boolean, IDebugType<ITypeRef, DIType>, IDebugType<ITypeRef, DIType>[])

Creates a function

Declaration

public IrFunction CreateFunction(string name, bool isVarArg, IDebugType<ITypeRef, DIType> returnType, params IDebugType<ITypeRef, DIType>[] argumentTypes)

Parameters

String	name	Name of the function
Boolean	isVarArg	Flag indicating if the function supports a variadic argument list
IDebugType<ITypeRef, DIType>	returnType	Return type of the function
IDebugType<ITypeRef, DIType>[]	argumentTypes	Arguments for the function

Returns

IrFunction

Function, matching the signature specified. This may be a previously declared or defined function or a new function if none matching the name and signature is already present.
