Christophe Lyon 8a7536e91d [ARM] Make _kill() a noreturn function.
AngelSWI_Reason_ReportException does not return accoring to the ARM
documentation, so it is valid to mark _kill() as noreturn.  This way,
the compiler does not warn about _exit() returning a value despite
being noreturn.

2018-10-01  Christophe Lyon  <christophe.lyon@linaro.org>

	* libgloss/arm/_exit.c (_exit): Declare _kill() as noreturn.

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.

Andy Koppe 3017f23f1c Avoid ARM SWI Seek when querying file position
Issuing an ARM semi-hosting Seek command when just querying file
position with SEEK_CUR and offset zero is unnecessary, because unlike
the lseek() Unix system call the Seek command does not actually return
the file position. For that reason, syscalls.c for ARM keeps track of
file position in the 'poslog', so we can just return that.

Moreover, since the Seek command only accepts an absolute file position,
SEEK_CUR operations are implemented by adding the relative offset to the
position in the poslog. If the host implements non-binary files with
implicit carriage return characters but doesn't discount those implicit
CRs when implementing Seek (by just mapping straight to Windows file
operations), this actually ended up wrongly changing file position when
using SEEK_CUR with offset zero or functions like ftell() or fgetpos()
that are based on that.

Also, use off_t rather than int for the poslog.

Commit 35998fc2fa fixed the buffer underun

backslash if the src path starts with a single backslash.

Sebastian Huber d13c84eb07 RTEMS: Add kvaddr_t and ksize_t
These types were introduced by FreeBSD commit:

"Make struct xinpcb and friends word-size independent.

Replace size_t members with ksize_t (uint64_t) and pointer members
(never used as pointers in userspace, but instead as unique
idenitifiers) with kvaddr_t (uint64_t). This makes the structs
identical between 32-bit and 64-bit ABIs.

On 64-bit bit systems, the ABI is maintained. On 32-bit systems,
this is an ABI breaking change. The ABI of most of these structs
was previously broken in r315662.  This also imposes a small API
change on userspace consumers who must handle kernel pointers
becoming virtual addresses.
