BFD_RELOC_SPARC_LO7
ENUMDOC
Some relocations we're using for SPARC V9 -- subject to change.
ENUM
BFD_RELOC_ALPHA_GPDISP_HI16
ENUMDOC
Alpha ECOFF 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).
ENUM
BFD_RELOC_ALPHA_GPDISP_LO16
ENUMDOC
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.
ENUM
BFD_RELOC_ALPHA_LITERAL
ENUMX
BFD_RELOC_ALPHA_LITUSE
ENUMDOC
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 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)
The GNU linker currently doesn't do any of this optimizing.
ENUM
BFD_RELOC_ALPHA_HINT
ENUMDOC
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.
ENUM
BFD_RELOC_MIPS_JMP
ENUMDOC
Bits 27..2 of the relocation address shifted right 2 bits;
simple reloc otherwise.
ENUM
BFD_RELOC_HI16
ENUMDOC
High 16 bits of 32-bit value; simple reloc.
ENUM
BFD_RELOC_HI16_S
ENUMDOC
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.
ENUM
BFD_RELOC_LO16
ENUMDOC
Low 16 bits.
ENUM
BFD_RELOC_PCREL_HI16_S
ENUMDOC
Like BFD_RELOC_HI16_S, but PC relative.

ENUM
BFD_RELOC_PPC_BA26

26 bit absolute branch, like BFD_RELOC_PPC_B26 but absolute.
ENUM
BFD_RELOC_PPC_TOC16
ENUMDOC
16 bit TOC relative reference.
ENUM
BFD_RELOC_CTOR
ENUMDOC
The type of reloc used to build a contructor table - at the moment
probably a 32 bit wide absolute relocation, but the target can choose.
It generally does map to one of the other relocation types.
