Subject: [PATCH] S390: Fix compiler invocation with "compile" command
On 64-bit S390 platforms the "compile" command always failed because
gcc was not invoked correctly. This patch fixes the compiler
invocation.
gdb/ChangeLog:
* s390-linux-tdep.c (s390_gcc_target_options): Not just handle
31-bit targets, but 64-bit targets as well.
(s390_gnu_triplet_regexp): New function.
(s390_gdbarch_init): Set the gcc_target_options gdbarch method for
64-bit targets as well. Set the gnu_triplet_regexp gdbarch
method.

Subject: [PATCH] S390: Support new vector register sections
The IBM z13 has new 128-bit wide vector registers v0-v31, where v0-v15
include the existing 64-bit wide floating point registers. The Linux
kernel presents the vector registers as two additional register sets,
one for the right halves of v0-v15 and another one for the full
registers v16-v31. Thus a new core file may contain two new register
note sections, and this patch adds support to binutils for them.

* readelf.c (get_note_type): Add NT_S390_VXRS_LOW and
NT_S390_VXRS_HIGH.
