The preceding commits add s390 64-bit (s390x) support in binutils to
generate SFrame stack trace information (.sframe section) in the
assembler from CFI directives (with option --gsframe), generate .sframe
section for linker-generated .plt section in the linker, and dump SFrame
information in objdump and readelf (with option --sframe).
binutils/
* NEWS: Announce s390 64-bit (s390x) SFrame V2 support in
as, ld, objdump, and readelf.
gas/
* NEWS: Update s390 64-bit (s390x) SFrame V2 support in
assembler.

+* On s390 64-bit (s390x), gas, ld, objdump, and readelf now support generating
+ and processing SFrame V2 stack trace information (.sframe). The assembler
+ generates SFrame info from CFI directives with option "--gsframe". The
+ linker generates SFrame info for the linker-generated .plt section and merges
+ all .sframe sections. Both objdump and readelf dump SFrame info with option
+ "--sframe[=<section-name>]".

* For SFrame stack trace format, the function start address in each SFrame
FDE has a changed encoding: The 32-bit signed integer now holds the offset
of the start PC of the associated function from the sfde_func_start_address
