As described in System V ABI, if an object file participates in dynamic linking, its program header table shall have an element of type PT_DYNAMIC. This `segment' contains the .dynamic section. A special symbol, _DYNAMIC, labels the section, which contains an array of the following structures.
typedef struct { Elf32_Sword d_tag; union { Elf32_Word d_val; Elf32_Addr d_ptr; } d_un; } Elf32_Dyn; extern Elf32_Dyn _DYNAMIC[]; typedef struct { Elf64_Sxword d_tag; union { Elf64_Xword d_val; Elf64_Addr d_ptr; } d_un; } Elf64_Dyn; extern Elf64_Dyn _DYNAMIC[]; |
Figure 14-1. Dynamic Structure
For each object with this type, d_tag
controls the interpretation of d_un
.
