Module Abi_amd64_relocationSource
abi_amd64_relocation contains types and definitions relating to ABI * specific relocation functionality for the AMD64 ABI.
x86-64 relocation types.
string_of_x86_64_relocation_type m produces a string representation of the * relocation type m.

Error.errorabi_amd64_apply_relocation rel val_map ef * calculates the effect of a relocation of type rel using relevant addresses, * offsets and fields represented by b_val, g_val, got_val, l_val, p_val, * s_val and z_val, stored in val_map with "B", "G", and so on as string * keys, which are: * * - B : Base address at which a shared-object has been loaded into memory * during execution. * - G : Represents the offset into the GOT at which the relocation's entry * will reside during execution. * - GOT: Address of the GOT. * - L : Represents the address or offset of the PLT entry for a symbol. * - P : Represents the address or offset of the storage unit being * relocated. * - S : Represents the value of the symbol whose index resides in the * relocation entry. * - Z : Represents the size of the symbol whose index resides in the * relocation entry. * * More details of the above can be found in the AMD64 ABI document's chapter * on relocations. * * The abi_amd64_apply_relocation function returns a relocation frame, either * indicating that the relocation is a copy relocation, or that some calculation * must be carried out at a certain location. See the comment above the * relocation_frame type in Abi_utilities.lem for more details.
