S390: Support guarded-storage core note sections
|
||
|
|
|
||
|
|
Newer Linux kernel versions offer two new register sets in support of the
|
||
|
|
z/Architecture's guarded storage facility: NT_S390_GS_CB, the
|
||
|
|
"guarded-storage registers", and NT_S390_GS_BC, the "guarded-storage
|
||
|
|
broadcast control block". This patch adds support for the respective core
|
||
|
|
notes sections to binutils.
|
||
|
|
|
||
|
|
bfd/ChangeLog:
|
||
|
|
* elf-bfd.h (elfcore_write_s390_gs_cb): Add prototype.
|
||
|
|
(elfcore_write_s390_gs_bc): Likewise.
|
||
|
|
* elf.c (elfcore_grok_s390_gs_cb): New function.
|
||

binutils/ChangeLog:

|
|
include/ChangeLog:
|
