S390: Add vector register support to gdbserver
|
||
|
|
|
||
|
|
On S/390 targets with vector registers, enable gdbserver to advertise
|
||
|
|
and handle the feature "org.gnu.gdb.s390.vx".
|
||
|
|
|
||
|
|
gdb/gdbserver/ChangeLog:
|
||
|
|
|
||
|
|
* Makefile.in (s390-vx-linux64.c, s390-tevx-linux64.c)
|
||
|
|
(s390x-vx-linux64.c, s390x-tevx-linux64.c): New rules.
|
||
|
|
(clean): Add "rm -f" for above C files.
|
||
|
|
* configure.srv (srv_regobj): Add s390-vx-linux64.o,
|
||
|
|
s390-tevx-linux64.o, s390x-vx-linux64.o, and s390x-tevx-linux64.o.
|
||
|
|
(srv_xmlfiles): Add s390-vx-linux64.xml, s390-tevx-linux64.xml,
|
||
|
|
s390x-vx-linux64.xml, s390x-tevx-linux64.xml, and s390-vx.xml.
|
||
|
|
* linux-s390-low.c (HWCAP_S390_VX): New macro.
|
||
|
|
(init_registers_s390_vx_linux64, init_registers_s390_tevx_linux64)
|
||
|
|
(init_registers_s390x_vx_linux64)
|
||
|
|
(init_registers_s390x_tevx_linux64)
|
||
|
|
(tdesc_s390_vx_linux64, tdesc_s390_tevx_linux64)
|
||
|
|
(tdesc_s390x_vx_linux64, tdesc_s390x_tevx_linux64): New extern
|
||
|
|
declarations.
|
||
|
|
(s390_fill_vxrs_low, s390_store_vxrs_low, s390_fill_vxrs_high)
|
||
|
|
(s390_store_vxrs_high): New functions.
|
||
|
|
(s390_regsets): Add entries for NT_S390_VXRS_LOW and
|
||
|
|
NT_S390_VXRS_HIGH.
|
||
|
|
(s390_arch_setup): Add logic for selecting one of the new target
|
||
|
|
descriptions. Activate the new vector regsets if applicable.
|
||
|
|
(initialize_low_arch): Also invoke init_registers_s390_vx_linux64,
|
||
|
|
init_registers_s390_tevx_linux64, init_registers_s390x_vx_linux64,
