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.

S390xPCRel32Dbl

s390x PC-relative 4-byte offset

S390xPLTRel32Dbl

s390x PC-relative 4-byte offset to PLT

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.

Aarch64TlsGdAdrPage21

AArch64 TLS GD Set an ADRP immediate field to the top 21 bits of the final address. Checks for overflow. This is equivalent to R_AARCH64_TLSGD_ADR_PAGE21 in the aaelf64

Aarch64TlsGdAddLo12Nc

AArch64 TLS GD Set the add immediate field to the low 12 bits of the final address. Does not check for overflow. This is equivalent to R_AARCH64_TLSGD_ADD_LO12_NC in the aaelf64

RiscvCall

procedure call. call symbol expands to the following assembly and relocation: auipc ra, 0 jalr ra, ra, 0

S390xTlsGd64

s390x TLS GD64 - 64-bit offset of tls_index for GD symbol in GOT

S390xTlsGdCall

s390x TLS GDCall - marker to enable optimization of TLS calls

Trait Implementations

impl Clone for Reloc

fn clone(&self) -> Reloc

Returns a copy 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 Display for Reloc

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

Display trait implementation drops the arch, since its used in contexts where the arch is already unambiguous, e.g. clif syntax with isa specified. In other contexts, use Debug.

impl PartialEq<Reloc> for Reloc

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

This method tests for self and other values to be equal, and is used by ==.

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

This method 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 StructuralEq for Reloc

impl StructuralPartialEq for Reloc
