Module goblin::elf::reloc [−][src]
Relocation computations
The following notation is used to describe relocation computations specific to x86_64 ELF.
- A: The addend used to compute the value of the relocatable field.
- B: The base address at which a shared object is loaded into memory during execution. Generally, a shared object file is built with a base virtual address of 0. However, the execution address of the shared object is different.
- G: The offset into the global offset table at which the address of the relocation entry’s symbol resides during execution.
- GOT: The address of the global offset table.
- L: The section offset or address of the procedure linkage table entry for a symbol.
- P: The section offset or address of the storage unit being relocated, computed using r_offset.
- S: The value of the symbol whose index resides in the relocation entry.
- Z: The size of the symbol whose index resides in the relocation entry.
Below are some common x86_64 relocation computations you might find useful:

R_X86_64_IRELATIVE | 37 | 64 | indirect (B + A) |
TLS information is at http://people.redhat.com/aoliva/writeups/TLS/RFC-TLSDESC-x86.txt
R_X86_64_IRELATIVE is similar to R_X86_64_RELATIVE except that
the value used in this relocation is the program address returned by the function,
which takes no arguments, at the address of the result of the corresponding
R_X86_64_RELATIVE relocation.
