Enum RegisterContaining 

pub(crate) enum RegisterContaining {
    Unallocated(Box<TaggedProgramInstruction>),
    Allocated(Address, Box<TaggedProgramInstruction>),
}

An RC-word.

See section 6-2.6 (“RC WORDS - RC BLOCK”).

Section 6-4.7 (“Use of Macro Instructions”) states that macro expansion may occur inside an RC-word (and expand to more than one word in the output binary) but this is not yet supported.

Variants

Unallocated(Box<TaggedProgramInstruction>)

Allocated(Address, Box<TaggedProgramInstruction>)

Implementations

impl RegisterContaining

fn instruction(&self) -> &TaggedProgramInstruction

fn symbol_uses( &self, block_id: BlockIdentifier, block_offset: Unsigned18Bit, ) -> impl Iterator<Item = Result<(SymbolName, SimpleSpan, SymbolUse), InconsistentSymbolUse>> + use<'_>

fn substitute_macro_parameters( &self, param_values: &MacroParameterBindings, on_missing: OnUnboundMacroParameter, macros: &BTreeMap<SymbolName, MacroDefinition>, ) -> Option<RegisterContaining>

fn assign_rc_word<R: RcAllocator>( self, source: RcWordSource, explicit_symtab: &mut ExplicitSymbolTable, implicit_symtab: &mut ImplicitSymbolTable, rc_allocator: &mut R, ) -> Result<RegisterContaining, RcWordAllocationFailure>

Trait Implementations

impl Clone for RegisterContaining

fn clone(&self) -> RegisterContaining

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegisterContaining

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

Formats the value using the given formatter.

impl Evaluate for RegisterContaining

fn evaluate<R: RcUpdater>( &self, ctx: &mut EvaluationContext<'_, R>, scope: ScopeIdentifier, ) -> Result<Unsigned36Bit, EvaluationFailure>

impl From<TaggedProgramInstruction> for RegisterContaining

fn from(inst: TaggedProgramInstruction) -> Self

Converts to this type from the input type.

impl PartialEq for RegisterContaining

fn eq(&self, other: &RegisterContaining) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Spanned for RegisterContaining

fn span(&self) -> SimpleSpan

impl Eq for RegisterContaining

impl StructuralPartialEq for RegisterContaining
