Enum AbiClass 

pub enum AbiClass {
    CallerSaved,
    CalleeSaved,
    Special,
}

ABI classification for registers based on preservation requirements.

This simplified classification focuses on whether registers need to be preserved across function calls, which is the most critical information for JIT compilation and register allocation.

Variants

CallerSaved

Caller-saved registers that don’t need to be preserved across calls.

These registers can be freely used by JIT-compiled functions without saving/restoring their values. Examples: argument registers, temp registers.

CalleeSaved

Callee-saved registers that must be preserved across calls.

If a JIT-compiled function uses these registers, it must save their values on entry and restore them before returning. Examples: saved registers.

Special

Special-purpose registers with specific ABI requirements.

These registers have specific roles (stack pointer, frame pointer, zero register, etc.) and require careful handling. Generally should be avoided in JIT code unless specifically needed for their intended purpose.

Trait Implementations

impl Clone for AbiClass

fn clone(&self) -> AbiClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AbiClass

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

Formats the value using the given formatter.

impl Display for AbiClass

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

Formats the value using the given formatter.

impl Hash for AbiClass

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

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for AbiClass

fn eq(&self, other: &AbiClass) -> 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.
