Relocation type indicators for MIPS processors.

Variants

Absolute = 0

The relocation is ignored.

RefHalf = 1

The high 16 bits of the target’s 32-bit VA.

RefWord = 2

The target’s 32-bit VA.

JMPAddr = 3

The low 26 bits of the target’s VA. This supports the MIPS J and JAL instructions.

RefHi = 4

The high 16 bits of the target’s 32-bit VA. This is used for the first instruction in a two-instruction sequence that loads a full address. This relocation must be immediately followed by a PAIR relocation whose SymbolTableIndex contains a signed 16-bit displacement that is added to the upper 16 bits that are taken from the location that is being relocated.

RefLo = 5

The low 16 bits of the target’s VA.

GPRel = 6

A 16-bit signed displacement of the target relative to the GP register.

Literal = 7

The same as MIPSRelocationType::GPRel.

Section = 10

The 16-bit section index of the section contains the target. This is used to support debugging information.

SecRel = 11

The 32-bit offset of the target from the beginning of its section. This is used to support debugging information and static thread local storage.

SecRelLo = 12

The low 16 bits of the 32-bit offset of the target from the beginning of its section.

SecRelHi = 13

The high 16 bits of the 32-bit offset of the target from the beginning of its section. A PAIR relocation must immediately follow this one. The SymbolTableIndex of the PAIR relocation contains a signed 16-bit displacement that is added to the upper 16 bits that are taken from the location that is being relocated.

JMPAddr16 = 16

The low 26 bits of the target’s VA. This supports the MIPS16 JAL instruction.

RefWordNb = 34

The target’s 32-bit RVA.

Pair = 37

The relocation is valid only when it immediately follows a REFHI or SECRELHI relocation. Its SymbolTableIndex contains a displacement and not an index into the symbol table.

Trait Implementations

impl Debug for MIPSRelocationType

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

Formats the value using the given formatter.

impl PartialEq for MIPSRelocationType

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
