Section Types are described in the
Intel® Itanium ™ Processor-specific Application Binary Interface,
Chapter 4.2.
LSB conforming implementations are not
required to use any sections in the range from
SHT_IA_64_LOPSREG to
SHT_IA_64_HIPSREG.
Additionally, LSB conforming implementations are not required
to support the
SHT_IA_64_PRIORITY_INIT
section, beyond the gABI requirements for the handling of
unrecognized section types, linking them into a contiguous section
in the object file created by the static linker.
