Corinna Vinschen 80bd01ef83 Add build mechanism to share common header files between machines
So far the build mechanism in newlib only allowed to either define
machine-specific headers, or headers shared between all machines.
In some cases, architectures are sufficiently alike to share header
files between them, but not with other architectures.  A good example
is ix86 vs. x86_64, which share certain traits with each other, but
not with other architectures.

Introduce a new configure variable called "shared_machine_dir".  This
dir can then be used for headers shared between architectures.

Jeff Johnston 007bc1923c Add gfortran support for AMD GCN
From: Kwok Cheung Yeung <kcy@codesourcery.com>

This patch adds enough support for constructors/destructors and OS functions
to be able to link and run gfortran programs on AMD GCN.

There's no actual ability to do I/O operations on this targets, besides
"write" to stdout and stderr, so most of the functions are just stubs.

Jeff Johnston 1787e9d033 AMD GCN Port contributed by Andrew Stubbs <ams@codesourcery.com>
Add support for the AMD GCN GPU architecture.  This is primarily intended for
use with OpenMP and OpenACC offloading.  It can also be used for stand-alone
programs, but this is intended mostly for testing the compiler and is not
expected to be useful in general.

The GPU architecture is highly parallel, and therefore Newlib must be
configured to use dynamic re-entrancy, and thread-safe malloc.

The only I/O available is a via a shared-memory interface provided by libgomp
and the gcn-run tool included with GCC.  At this time this is limited to
stdout, argc/argv, and the return code.

Hans-Peter Nilsson e3ddbeb84c Committed, CRIS port: fix fallout from time_t defaulting to 64 bits, part 2
It's been a while...  I see the CRIS port broke with the
time_t-default-to-64-bit change, observable by a few test-cases in the gcc
fortran(!) tests failing, regressing when trying a recent newlib.

This is a two-part belt-and-suspenders change: adjust the CRIS port
gettimeofday syscall (the only one in newlib/CRIS passing a time_t or
struct timeval) to handle a userspace 64-bit time_t and secondly default
time_t to 32-bit long anyway.  I considered making the local
"kernel_timeval" copy in _gettimeofday conditional on (userspace) time_t
being 64 bits, but thought it not worth bothering with the few move insns.
The effect of a 64-bit time_t is however observable as longer simulation
time when running the gcc testsuite and as bigger binaries without any
actual upside from the larger time_t size, so I thought better make the
default for this port go back to being a "long" again.

Tested by running the gcc testsuite over the three combinations of two
parts of the patch and observing the expected changes.  Committed.

	* configure.host (cris, crisv32): Default to "long" time_t.

Sebastian Huber f9205f1d47 Let RTEMS provide clock()
Newlib uses _times_r() in clock().  The problem is that the _times_r()
clock frequency is defined by sysconf(_SC_CLK_TCK).  The clock frequency
of clock() is the constant CLOCKS_PER_SEC.

FreeBSD uses getrusage() for clock().  Since RTEMS has only one process,
the implementation can be simplified.

When running RTEMS paravirtualized in user space, the cli/sti instructions
can't be used. But I can't see why they are needed in either user or

This code is unmodified since the beginning of the repository, so I have
no insight into why it was done. I may even have been the one to add them.
Absolutely no idea except they aren't necessary.
