Andreas Arnez 550bdf96ca S390: Add vector register support to gdb
Recognize S/390 targets with the new vector feature and present their
vector registers appropriately: as 32 new 128-bit wide registers
v0-v31, where the first 16 embed the floating point registers f0-f15.
Each of the full registers v0-v15 is modelled as a pseudo register.

gdb/ChangeLog:

	* s390-linux-nat.c (have_regset_vxrs): New static variable.
	(s390_linux_fetch_inferior_registers): Handle vector registers, if
	present.
	(s390_linux_store_inferior_registers): Likewise.
	(s390_get_hwcap): Remove function.  Embed its logic...
	(s390_read_description): ...here.  Yield a target description with
	vector registers if applicable.
	* s390-linux-tdep.c: Include "features/s390-vx-linux64.c",
	"features/s390-tevx-linux64.c", "features/s390x-vx-linux64.c", and
	"features/s390x-tevx-linux64.c".
	(struct gdbarch_tdep) <v0_full_regnum>: New field.
	(s390_dwarf_regmap): Add vector registers.  Remove bogus entries
	for "GNU/Linux-specific registers".
	(s390_dwarf_reg_r0l): New enum value.
	(s390_dwarf_reg_to_regnum): Support vector registers.
	(s390_adjust_frame_regnum): Adjust pseudo DWARF register numbers
	of GPR lower halves.
	(regnum_is_vxr_full): New function.
	(s390_register_name): New function.
	(s390_pseudo_register_name): Handle v0-v15, which are composed of
	f0-f15 and v0l-v15l.
	(s390_pseudo_register_type): Likewise.
	(s390_pseudo_register_read): Likewise.
	(s390_pseudo_register_write): Likewise.
	(s390_value_from_register): Account for the fact that values are
	placed left-justified in vector registers.
	(s390_pseudo_register_reggroup_p): Add pseudo registers v0-v15 to
	the vector reggroup and omit them from the general reggroup.
	(s390_regmap_vxrs_low, s390_regmap_vxrs_high): New register maps.
	(s390_vxrs_low_regset, s390_vxrs_high_regset): New regsets.
	(s390_iterate_over_regset_sections): Add iterations for the two
	new vector regsets.
	(s390_core_read_description): Yield a target description with
	vector registers if applicable.
	(s390_gdbarch_init): Handle target descriptions with vector
	registers.  Add "register_name" gdbarch method.
	(_initialize_s390_tdep): Call new tdesc initialization functions.
	* s390-linux-tdep.h (HWCAP_S390_VX): New macro.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
