Information about how the result of the relocation operation is encoded in the place.

This is usually architecture specific, such as specifying an addressing mode or a specific instruction.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unknown

The relocation encoding is unknown.

Generic

Generic encoding.

X86Signed

x86 sign extension at runtime.

Used with RelocationKind::Absolute.

X86RipRelative

x86 rip-relative addressing.

The RelocationKind must be PC relative.

X86RipRelativeMovq

x86 rip-relative addressing in movq instruction.

The RelocationKind must be PC relative.

X86Branch

x86 branch instruction.

The RelocationKind must be PC relative.

S390xDbl

s390x PC-relative offset shifted right by one bit.

The RelocationKind must be PC relative.

AArch64Call

AArch64 call target.

The RelocationKind must be PC relative.

LoongArchBranch

LoongArch branch offset with two trailing zeros.

The RelocationKind must be PC relative.

SharcTypeA

SHARC+ 48-bit Type A instruction

Represents these possible variants, each with a corresponding R_SHARC_* constant:

• 24-bit absolute address
• 32-bit absolute address
• 6-bit relative address
• 24-bit relative address
• 6-bit absolute address in the immediate value field
• 16-bit absolute address in the immediate value field

SharcTypeB

SHARC+ 32-bit Type B instruction

Represents these possible variants, each with a corresponding R_SHARC_* constant:

• 6-bit absolute address in the immediate value field
• 7-bit absolute address in the immediate value field
• 16-bit absolute address
• 6-bit relative address

E2KLit

E2K 64-bit value stored in two LTS

Memory representation:

0: LTS1 = value[63:32]
4: LTS0 = value[31:0]

E2KDisp

E2K 28-bit value stored in CS0

Trait Implementations

impl Clone for RelocationEncoding

fn clone(&self) -> RelocationEncoding

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RelocationEncoding

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

Formats the value using the given formatter.

impl Hash for RelocationEncoding

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 RelocationEncoding

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