Struct PhiValue

source
pub struct PhiValue<'ctx> { /* private fields */ }
Expand description

A Phi Instruction returns a value based on which basic block branched into the Phi’s containing basic block.

Implementations§

source§

impl<'ctx> PhiValue<'ctx>

source

pub unsafe fn new(value: LLVMValueRef) -> Self

Get a value from an LLVMValueRef.

§Safety

The ref must be valid and of type phi.

source

pub fn add_incoming( self, incoming: &[(&dyn BasicValue<'ctx>, BasicBlock<'ctx>)], )

source

pub fn count_incoming(self) -> u32

source

pub fn get_incoming( self, index: u32, ) -> Option<(BasicValueEnum<'ctx>, BasicBlock<'ctx>)>

source

pub unsafe fn get_incoming_unchecked( self, index: u32, ) -> (BasicValueEnum<'ctx>, BasicBlock<'ctx>)

§Safety

The index must be smaller PhiValue::count_incoming.

source

pub fn get_incomings(self) -> IncomingIter<'ctx>

Get an incoming edge iterator.

source

pub fn get_name(&self) -> &CStr

Gets the name of a ArrayValue. If the value is a constant, this will return an empty string.

source

pub fn set_name(self, name: &str)

source

pub fn is_null(self) -> bool

source

pub fn is_undef(self) -> bool

source

pub fn as_instruction(self) -> InstructionValue<'ctx>
