[PATCH 1/3] libelf: Sync elf.h from glibc.
Mark Wielaard
mark@klomp.org
Thu Mar 24 23:14:36 GMT 2022
Adds EM_INTELGT, NT_ARM_TAGGED_ADDR_CTRL, NT_ARM_PAC_ENABLED_KEYS,
ELF_NOTE_FDO, NT_FDO_PACKAGING_METADATA and OpenRISC 1000 specific
relocs.
It also adds and renames some GNU_PROPERTY constants. But none of the
constants the elfutils code uses was renamed or given a different
constant value.
dwelf_elf_e_machine_string was updated to handle EM_INTELGT.
