Struct PhiValue

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

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

Implementations

impl<'ctx> PhiValue<'ctx>

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

Get a value from an LLVMValueRef.

Safety

The ref must be valid and of type phi.

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

pub fn count_incoming(self) -> u32

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

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

Safety

The index must be smaller PhiValue::count_incoming.

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

Get an incoming edge iterator.

pub fn get_name(&self) -> &CStr

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

pub fn set_name(self, name: &str)

pub fn is_null(self) -> bool

pub fn is_undef(self) -> bool

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

pub fn replace_all_uses_with(self, other: &PhiValue<'ctx>)

pub fn as_basic_value(self) -> BasicValueEnum<'ctx>

Trait Implementations

impl<'ctx> AnyValue<'ctx> for PhiValue<'ctx>

fn as_any_value_enum(&self) -> AnyValueEnum<'ctx>

Returns an enum containing a typed version of AnyValue.

fn print_to_string(&self) -> LLVMString

Prints a value to a LLVMString

fn is_poison(&self) -> bool

Available on crate features llvm12-0 or llvm13-0 or llvm14-0 or llvm15-0 or llvm16-0 or llvm17-0 or llvm18-0 only.

Returns whether the value is poison

impl AsValueRef for PhiValue<'_>

impl<'ctx> Clone for PhiValue<'ctx>

fn clone(&self) -> PhiValue<'ctx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'ctx> Debug for PhiValue<'ctx>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for PhiValue<'_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'ctx> From<PhiValue<'ctx>> for AnyValueEnum<'ctx>

fn from(value: PhiValue<'_>) -> AnyValueEnum<'_>

Converts to this type from the input type.

impl<'ctx> Hash for PhiValue<'ctx>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

impl<'ctx> PartialEq<AnyValueEnum<'ctx>> for PhiValue<'ctx>

fn eq(&self, other: &AnyValueEnum<'ctx>) -> bool
