/* 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). */
/* 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. */
/* The ELF GPDISP relocation is exactly the same as the GPDISP_HI16
relocation except that there is no accompanying GPDISP_LO16
relocation. */
/* 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) */
/* 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. */
/* The LINKAGE relocation outputs a linkage pair in the object file,
which is filled by the linker. */
/* The CODEADDR relocation outputs a STO_CA in the object file,
