64-bit SPARC: Relocation Types (Linker and Libraries Guide)

Linker and Libraries Guide

The following notation, used in relocation calculation, is unique to 64–bit SPARC.

O: The secondary addend used to compute the value of the relocation field. This addend is extracted from the r_info field by applying the ELF64_R_TYPE_DATA macro.

The relocations that are listed in the following table extend, or alter, the relocations defined for 32–bit SPARC. See SPARC: Relocation Types.

Table 7–14 64-bit SPARC: ELF Relocation Types


Name	Value	Field	Calculation
`R_SPARC_HI22`	`9`	`V-imm22`	`(S + A) >> 10`
`R_SPARC_GLOB_DAT`	`20`	`V-xword64`	`S + A`
`R_SPARC_RELATIVE`	`22`	`V-xword64`	`B + A`
`R_SPARC_64`	`32`	`V-xword64`	`S + A`
`R_SPARC_OLO10`	`33`	`V-simm13`	`((S + A) & 0x3ff) + O`
`R_SPARC_DISP64`	`46`	`V-xword64`	`S + A - P`
`R_SPARC_PLT64`	`47`	`V-xword64`	`L + A`
`R_SPARC_REGISTER`	`53`	`V-xword64`	`S + A`
`R_SPARC_UA64`	`54`	`V-xword64`	`S + A`
`R_SPARC_H34`	`85`	`V-imm22`	`(S + A) >> 12`
`R_SPARC_SIZE64`	`87`	`V-xword64`	`Z + A`

The following relocation type has semantics beyond simple calculation.

R_SPARC_OLO10: Resembles R_SPARC_LO10, except that an extra offset is added to make full use of the 13-bit signed immediate field.
