Detailed Description

Functions in this group relate to arguments/parameters on functions.

Functions in this group expect LLVMValueRef instances that correspond to llvm::Function instances.

Function Documentation

void LLVMAddAttribute	(	LLVMValueRef	Arg,
		LLVMAttribute	PA
	)

Add an attribute to a function argument.

See also:: llvm::Argument::addAttr()

Definition at line 1539 of file Core.cpp.

References llvm::ARM_PROC::A, llvm::Argument::addAttr(), llvm::Argument::getArgNo(), and llvm::Value::getContext().

unsigned LLVMCountParams ( LLVMValueRef Fn )

Obtain the number of parameters in a function.

See also:: llvm::Function::arg_size()

Definition at line 1483 of file Core.cpp.

LLVMAttribute LLVMGetAttribute ( LLVMValueRef Arg )

Get an attribute from a function argument.

Definition at line 1551 of file Core.cpp.

References llvm::ARM_PROC::A, llvm::Argument::getArgNo(), llvm::Function::getAttributes(), and llvm::Argument::getParent().

LLVMValueRef LLVMGetFirstParam ( LLVMValueRef Fn )

Obtain the first parameter to a function.

See also:: llvm::Function::arg_begin()

Definition at line 1507 of file Core.cpp.

References llvm::Function::arg_begin(), llvm::Function::arg_end(), I, and llvm::wrap().

LLVMValueRef LLVMGetLastParam ( LLVMValueRef Fn )

Obtain the last parameter to a function.

See also:: llvm::Function::arg_end()

Definition at line 1515 of file Core.cpp.

References llvm::Function::arg_begin(), llvm::Function::arg_end(), I, and llvm::wrap().

LLVMValueRef LLVMGetNextParam ( LLVMValueRef Arg )

Obtain the next parameter to a function.

This takes a LLVMValueRef obtained from LLVMGetFirstParam() (which is actually a wrapped iterator) and obtains the next parameter from the underlying iterator.

Definition at line 1523 of file Core.cpp.

References llvm::ARM_PROC::A, llvm::Function::arg_end(), llvm::Argument::getParent(), I, and llvm::wrap().

LLVMValueRef LLVMGetParam	(	LLVMValueRef	Fn,
		unsigned	Index
	)

Obtain the parameter at the specified index.

Parameters are indexed from 0.

See also:: llvm::Function::arg_begin()

Definition at line 1496 of file Core.cpp.

References llvm::wrap().

LLVMValueRef LLVMGetParamParent ( LLVMValueRef Inst )

Obtain the function to which this argument belongs.

Unlike other functions in this group, this one takes a LLVMValueRef that corresponds to a llvm::Attribute.

The returned LLVMValueRef is the llvm::Function to which this argument belongs.

Definition at line 1503 of file Core.cpp.

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

void LLVMGetParams	(	LLVMValueRef	Fn,
		LLVMValueRef *	Params
	)

Obtain the parameters in a function.

The takes a pointer to a pre-allocated array of LLVMValueRef that is at least LLVMCountParams() long. This array will be filled with LLVMValueRef instances which correspond to the parameters the function receives. Each LLVMValueRef corresponds to a llvm::Argument instance.

See also:: llvm::Function::arg_begin()

Definition at line 1489 of file Core.cpp.

References llvm::Function::arg_begin(), llvm::Function::arg_end(), I, and llvm::wrap().

LLVMValueRef LLVMGetPreviousParam ( LLVMValueRef Arg )

Obtain the previous parameter to a function.

This is the opposite of LLVMGetNextParam().

Definition at line 1531 of file Core.cpp.

References llvm::ARM_PROC::A, llvm::Function::arg_begin(), llvm::Argument::getParent(), I, and llvm::wrap().

void LLVMRemoveAttribute	(	LLVMValueRef	Arg,
		LLVMAttribute	PA
	)

Remove an attribute from a function argument.

See also:: llvm::Argument::removeAttr()

Definition at line 1545 of file Core.cpp.

References llvm::ARM_PROC::A, llvm::Argument::getArgNo(), llvm::Value::getContext(), and llvm::Argument::removeAttr().

void LLVMSetParamAlignment	(	LLVMValueRef	Arg,
		unsigned	align
	)

Set the alignment for a function parameter.
