2.10.2 The howto manager

When an application wants to create a relocation, but doesn't know what the target machine might call it, it can find out by using this bit of code.

2.10.2.1 bfd_reloc_code_type

Description
The insides of a reloc code. The idea is that, eventually, there will be one enumerator for every type of relocation we ever do. Pass one of these values to bfd_reloc_type_lookup, and it'll return a howto pointer.

This does mean that the application must determine the correct enumerator value; you can't get a howto pointer from a random set of attributes.

Here are the possible values for enum bfd_reloc_code_real:

— : BFD_RELOC_64
— : BFD_RELOC_32
— : BFD_RELOC_26
— : BFD_RELOC_24
— : BFD_RELOC_16
— : BFD_RELOC_14
— : BFD_RELOC_8

Basic absolute relocations of N bits.

— : BFD_RELOC_64_PCREL
— : BFD_RELOC_32_PCREL
— : BFD_RELOC_24_PCREL
— : BFD_RELOC_16_PCREL
— : BFD_RELOC_12_PCREL
— : BFD_RELOC_8_PCREL

PC-relative relocations. Sometimes these are relative to the address of the relocation itself; sometimes they are relative to the start of the section containing the relocation. It depends on the specific target.

The 24-bit relocation is used in some Intel 960 configurations.

— : BFD_RELOC_32_SECREL

Section relative relocations. Some targets need this for DWARF2.

— : BFD_RELOC_32_GOT_PCREL
— : BFD_RELOC_16_GOT_PCREL
— : BFD_RELOC_8_GOT_PCREL
— : BFD_RELOC_32_GOTOFF
— : BFD_RELOC_16_GOTOFF
— : BFD_RELOC_LO16_GOTOFF
— : BFD_RELOC_HI16_GOTOFF
— : BFD_RELOC_HI16_S_GOTOFF
— : BFD_RELOC_8_GOTOFF
— : BFD_RELOC_64_PLT_PCREL
— : BFD_RELOC_32_PLT_PCREL
— : BFD_RELOC_24_PLT_PCREL
— : BFD_RELOC_16_PLT_PCREL
— : BFD_RELOC_8_PLT_PCREL
— : BFD_RELOC_64_PLTOFF
— : BFD_RELOC_32_PLTOFF
— : BFD_RELOC_16_PLTOFF
— : BFD_RELOC_LO16_PLTOFF
— : BFD_RELOC_HI16_PLTOFF
— : BFD_RELOC_HI16_S_PLTOFF
— : BFD_RELOC_8_PLTOFF

For ELF.

— : BFD_RELOC_68K_GLOB_DAT
— : BFD_RELOC_68K_JMP_SLOT
— : BFD_RELOC_68K_RELATIVE

Relocations used by 68K ELF.

— : BFD_RELOC_32_BASEREL
— : BFD_RELOC_16_BASEREL
— : BFD_RELOC_LO16_BASEREL
— : BFD_RELOC_HI16_BASEREL
— : BFD_RELOC_HI16_S_BASEREL
— : BFD_RELOC_8_BASEREL
— : BFD_RELOC_RVA

Linkage-table relative.

— : BFD_RELOC_8_FFnn

Absolute 8-bit relocation, but used to form an address like 0xFFnn.

— : BFD_RELOC_32_PCREL_S2
— : BFD_RELOC_16_PCREL_S2
— : BFD_RELOC_23_PCREL_S2

These PC-relative relocations are stored as word displacements – i.e., byte displacements shifted right two bits. The 30-bit word displacement (<<32_PCREL_S2>> – 32 bits, shifted 2) is used on the SPARC. (SPARC tools generally refer to this as <<WDISP30>>.) The signed 16-bit displacement is used on the MIPS, and the 23-bit displacement is used on the Alpha.

— : BFD_RELOC_HI22
— : BFD_RELOC_LO10

High 22 bits and low 10 bits of 32-bit value, placed into lower bits of the target word. These are used on the SPARC.

— : BFD_RELOC_GPREL16
— : BFD_RELOC_GPREL32

For systems that allocate a Global Pointer register, these are displacements off that register. These relocation types are handled specially, because the value the register will have is decided relatively late.

— : BFD_RELOC_I960_CALLJ

Reloc types used for i960/b.out.

— : BFD_RELOC_NONE
— : BFD_RELOC_SPARC_WDISP22

— : BFD_RELOC_SPARC_GOTDATA_OP_LOX10
— : BFD_RELOC_SPARC_GOTDATA_OP

SPARC ELF relocations. There is probably some overlap with other relocation types already defined.

— : BFD_RELOC_SPARC_BASE13
— : BFD_RELOC_SPARC_BASE22

I think these are specific to SPARC a.out (e.g., Sun 4).

— : BFD_RELOC_SPU_HI16
— : BFD_RELOC_SPU_PPU32
— : BFD_RELOC_SPU_PPU64

SPU Relocations.

— : BFD_RELOC_ALPHA_GPDISP_HI16

Alpha ECOFF and ELF relocations. Some of these treat the symbol or "addend" in some special way. For GPDISP_HI16 ("gpdisp") relocations, the symbol is ignored when writing; when reading, it will be the absolute section symbol. The addend is the displacement in bytes of the "lda" instruction from the "ldah" instruction (which is at the address of this reloc).

— : BFD_RELOC_ALPHA_GPDISP_LO16

For GPDISP_LO16 ("ignore") relocations, the symbol is handled as with GPDISP_HI16 relocs. The addend is ignored when writing the relocations out, and is filled in with the file's GP value on reading, for convenience.

— : BFD_RELOC_ALPHA_GPDISP

The ELF GPDISP relocation is exactly the same as the GPDISP_HI16 relocation except that there is no accompanying GPDISP_LO16 relocation.

— : BFD_RELOC_ALPHA_LITERAL
— : BFD_RELOC_ALPHA_ELF_LITERAL
— : BFD_RELOC_ALPHA_LITUSE

The Alpha LITERAL/LITUSE relocs are produced by a symbol reference; the assembler turns it into a LDQ instruction to load the address of the symbol, and then fills in a register in the real instruction.

The LITERAL reloc, at the LDQ instruction, refers to the .lita section symbol. The addend is ignored when writing, but is filled in with the file's GP value on reading, for convenience, as with the GPDISP_LO16 reloc.

The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16. It should refer to the symbol to be referenced, as with 16_GOTOFF, but it generates output not based on the position within the .got section, but relative to the GP value chosen for the file during the final link stage.

The LITUSE reloc, on the instruction using the loaded address, gives information to the linker that it might be able to use to optimize away some literal section references. The symbol is ignored (read as the absolute section symbol), and the "addend" indicates the type of instruction using the register: 1 - "memory" fmt insn 2 - byte-manipulation (byte offset reg) 3 - jsr (target of branch)

— : BFD_RELOC_ALPHA_HINT

The HINT relocation indicates a value that should be filled into the "hint" field of a jmp/jsr/ret instruction, for possible branch- prediction logic which may be provided on some processors.

— : BFD_RELOC_ALPHA_LINKAGE

The LINKAGE relocation outputs a linkage pair in the object file, which is filled by the linker.

— : BFD_RELOC_ALPHA_CODEADDR

The CODEADDR relocation outputs a STO_CA in the object file, which is filled by the linker.

— : BFD_RELOC_ALPHA_GPREL_HI16
— : BFD_RELOC_ALPHA_GPREL_LO16

The GPREL_HI/LO relocations together form a 32-bit offset from the GP register.

— : BFD_RELOC_ALPHA_BRSGP

Like BFD_RELOC_23_PCREL_S2, except that the source and target must share a common GP, and the target address is adjusted for STO_ALPHA_STD_GPLOAD.

— : BFD_RELOC_HI16_S

High 16 bits of 32-bit value but the low 16 bits will be sign extended and added to form the final result. If the low 16 bits form a negative number, we need to add one to the high value to compensate for the borrow when the low bits are added.

MIPS16 high 16 bits of 32-bit value but the low 16 bits will be sign extended and added to form the final result. If the low 16 bits form a negative number, we need to add one to the high value to compensate for the borrow when the low bits are added.

— : BFD_RELOC_VTABLE_ENTRY

These two relocations are used by the linker to determine which of the entries in a C++ virtual function table are actually used. When the –gc-sections option is given, the linker will zero out the entries that are not used, so that the code for those functions need not be included in the output.

VTABLE_INHERIT is a zero-space relocation used to describe to the linker the inheritance tree of a C++ virtual function table. The relocation's symbol should be the parent class' vtable, and the relocation should be located at the child vtable.

VTABLE_ENTRY is a zero-space relocation that describes the use of a virtual function table entry. The reloc's symbol should refer to the table of the class mentioned in the code. Off of that base, an offset describes the entry that is being used. For Rela hosts, this offset is stored in the reloc's addend. For Rel hosts, we are forced to put this offset in the reloc's section offset.
