Andreas Arnez 417c80f9e4 S390: Vector ABI support
With the S390 vector ABI, vector registers are used for passing vector
arguments and for returning a vector.  Support this ABI in inferior
function calls and when setting or retrieving a function's return
value.

gdb/ChangeLog:

	* s390-linux-tdep.c: Include "elf/s390.h" and "elf-bfd.h".
	(enum s390_vector_abi_kind): New enum.
	(struct gdbarch_tdep)<vector_abi>: New field.
	(s390_effective_inner_type): Add parameter min_size.  Stop
	unwrapping if the inner type is smaller than min_size.
	(s390_function_arg_float): Adjust call to
	s390_effective_inner_type.
	(s390_function_arg_vector): New function.
	(s390_function_arg_integer): Adjust comment.
	(struct s390_arg_state)<vr>: New field.
	(s390_handle_arg): Add parameter 'is_unnamed'.  Pass vector
	arguments according to vector ABI when appropriate.
	(s390_push_dummy_call): Initialize the argument state's field
	'vr'.  Adjust calls to s390_handle_arg.
	(s390_register_return_value): Handle vector return values.
	(s390_return_value): Apply the "register" return value convention
	to a vector when appropriate.
	(s390_gdbarch_init): Initialize tdep->vector_abi.
	* NEWS: Announce S390 vector ABI support.

		   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.
