commit 9f5989ef192efab3d477fd6cc8712a8fd53e1856
Author: John Baldwin <jhb@FreeBSD.org>
Date: Fri Apr 1 13:16:46 2022 -0700
Recognize FreeBSD core dump note for x86 segment base registers.
This core dump note contains the value of the base address of the %fs
and %gs segments for both i386 and amd64 core dumps. It is primarily
useful in resolving the address of TLS variables in core dumps.
binutils/ChangeLog:
* readelf.c (get_freebsd_elfcore_note_type): Handle
NT_FREEBSD_X86_SEGBASES.
include/ChangeLog:
* elf/common.h (NT_FREEBSD_X86_SEGBASES): Define.
(cherry picked from commit a171378aa472fab0407dc1f99e8e7782286719ed)
