Relocation kinds for every ISA

Variants

Abs4

absolute 4-byte

Abs8

absolute 8-byte

X86PCRel4

x86 PC-relative 4-byte

X86CallPCRel4

x86 call to PC-relative 4-byte

X86CallPLTRel4

x86 call to PLT-relative 4-byte

X86GOTPCRel4

x86 GOT PC-relative 4-byte

X86SecRel

The 32-bit offset of the target from the beginning of its section. Equivalent to IMAGE_REL_AMD64_SECREL. See: PE Format

Arm32Call

Arm32 call target

Arm64Call

Arm64 call target. Encoded as bottom 26 bits of instruction. This value is sign-extended, multiplied by 4, and added to the PC of the call instruction to form the destination address.

ElfX86_64TlsGd

Elf x86_64 32 bit signed PC relative offset to two GOT entries for GD symbol.

MachOX86_64Tlv

Mach-O x86_64 32 bit signed PC relative offset to a __thread_vars entry.

MachOAarch64TlsAdrPage21

Mach-O Aarch64 TLS PC-relative distance to the page of the TLVP slot.

MachOAarch64TlsAdrPageOff12

Mach-O Aarch64 TLS Offset within page of TLVP slot.

Aarch64TlsDescAdrPage21

Aarch64 TLSDESC Adr Page21 This is equivalent to R_AARCH64_TLSDESC_ADR_PAGE21 in the aaelf64

Aarch64TlsDescLd64Lo12

Aarch64 TLSDESC Ld64 Lo12 This is equivalent to R_AARCH64_TLSDESC_LD64_LO12 in the aaelf64

Aarch64TlsDescAddLo12

Aarch64 TLSDESC Add Lo12 This is equivalent to R_AARCH64_TLSGD_ADD_LO12 in the aaelf64

Aarch64TlsDescCall

Aarch64 TLSDESC Call This is equivalent to R_AARCH64_TLSDESC_CALL in the aaelf64

Aarch64AdrGotPage21

AArch64 GOT Page Set the immediate value of an ADRP to bits 32:12 of X; check that –2^32 <= X < 2^32 This is equivalent to R_AARCH64_ADR_GOT_PAGE (311) in the aaelf64

Aarch64Ld64GotLo12Nc

AArch64 GOT Low bits Set the LD/ST immediate field to bits 11:3 of X. No overflow check; check that X&7 = 0 This is equivalent to R_AARCH64_LD64_GOT_LO12_NC (312) in the aaelf64

RiscvAbs8

RISC-V Absolute address: 64-bit address.

RiscvCallPlt

RISC-V Call PLT: 32-bit PC-relative function call, macros call, tail (PIC)

Despite having PLT in the name, this relocation is also used for normal calls. The non-PLT version of this relocation has been deprecated.

This is the R_RISCV_CALL_PLT relocation from the RISC-V ELF psABI document. https://github.com/riscv-non-isa/riscv-elf-psabi-doc/blob/master/riscv-elf.adoc#procedure-calls

RiscvTlsGdHi20

RISC-V TLS GD: High 20 bits of 32-bit PC-relative TLS GD GOT reference,

This is the R_RISCV_TLS_GD_HI20 relocation from the RISC-V ELF psABI document. https://github.com/riscv-non-isa/riscv-elf-psabi-doc/blob/master/riscv-elf.adoc#global-dynamic

RiscvPCRelLo12I

Low 12 bits of a 32-bit PC-relative relocation (I-Type instruction)

This is the R_RISCV_PCREL_LO12_I relocation from the RISC-V ELF psABI document. https://github.com/riscv-non-isa/riscv-elf-psabi-doc/blob/master/riscv-elf.adoc#pc-relative-symbol-addresses

RiscvGotHi20

High 20 bits of a 32-bit PC-relative GOT offset relocation

This is the R_RISCV_GOT_HI20 relocation from the RISC-V ELF psABI document. https://github.com/riscv-non-isa/riscv-elf-psabi-doc/blob/master/riscv-elf.adoc#pc-relative-symbol-addresses

Trait Implementations

impl Clone for Reloc

fn clone(&self) -> Reloc

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Reloc

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

Formats the value using the given formatter.

impl Hash for Reloc

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 Reloc

fn eq(&self, other: &Reloc) -> 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 Copy for Reloc

impl Eq for Reloc

impl StructuralPartialEq for Reloc
