Struct Executed 

pub struct Executed {
    pub write_back: WriteBack,
    pub stall_cycles: u32,
    pub mem: Option<MemOp>,
    pub redirect: Option<Redirect>,
    pub cop0: Option<Cop0Access>,
    pub link: Option<u8>,
}

The outcome of executing one instruction in EX.

Fields

write_back: WriteBack

What to commit at WB.

stall_cycles: u32

Extra PCycles the whole pipeline stalls for (multiply/divide only).

mem: Option<MemOp>

A memory access for DC to perform, if any.

redirect: Option<Redirect>

A control-flow redirect, if this was a taken branch, a jump, or an untaken branch-likely.

cop0: Option<Cop0Access>

A COP0 access for DC (read) or WB (write) to perform.

link: Option<u8>

The GPR a jump-and-link writes its return address to, if any.

Carried separately from write_back because the value cannot be computed here: the link is the address of the instruction that runs after this one’s delay slot, which is pc + 8 only when the jump is not itself in a delay slot. EX fills it in from the live next_pc, which is that address by construction. See the jump/branch helper in this module, and accuracy ledger C-19.

Trait Implementations

impl Clone for Executed

fn clone(&self) -> Executed

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Executed

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

Formats the value using the given formatter.

impl Default for Executed

fn default() -> Executed

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Executed

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Executed

fn eq(&self, other: &Executed) -> 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 Serialize for Executed

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Executed

impl Eq for Executed

impl StructuralPartialEq for Executed
