In addition to the requirements for ELF sections described in the generic LSB Core specification, conforming implementations shall support architecture specific sections as described below.
Note: The System V Application Binary Interface AMD64 Architecture Processor Supplement specifies some architecture specific section flags and section types that are not required by LSB-conforming systems.
The following architecture-specific sections are defined in the System V Application Binary Interface AMD64 Architecture Processor Supplement.
Table 9-1. ELF Special Sections
This section holds the global offset table.
This section holds the procedure linkage table.
Note: Since LSB-conforming implementations are not required to support the large code model, it is not necessary for them to provide support for the additional special sections for the large code model described in the System V Application Binary Interface AMD64 Architecture Processor Supplement.
Also, the System V Application Binary Interface AMD64 Architecture Processor Supplement specifies a section .eh_frame, with a type of SHT_AMD64_UNWIND. This section is described in the generic LSB-Core specification, but with type SHT_PROGBITS. This specification does not require support for the SHT_AMD64_UNWIND section type.
The following additional sections are defined here.
Table 9-2. Additional Special Sections
This section holds RELA type relocation information for all sections of a shared library except the PLT.
This section holds RELA type relocation information for the PLT section of a shared library or dynamically linked application.
