[PATCH, OR1K] libgloss boards

Hi again,

the libor1k and crt0 depend on some symbols defined by the boards and 
call ini/exit functions there. Those are the pre-defined boards.

[PATCH, OR1K] crt0

Hi again,

this patch contains the basic build files for ligbloss/or1k and the C 
runtime. It has some external dependencies that are fulfilled by libor1k 
and the board files that will follow.

Bye,
Stefan

[PATCH, OR1K] Support for optional delay slot

Dear all,

this patch adds support for the different variants of delay slots (its 
optional).
or1knd is the machine name without delay slot, or1k is the (standard) 
one with delay slot, and for compatibility we simply put a nop into the 
delay slot.

Bye,
Stefan

[PATCH, OR1K] Don't save parameter registers in setjmp/longjmp

Dear all,

this patch removes the save/restore of the parameter registers r3-r8 in 
setjmp/longjmp as they are not preserved across function calls.

OpenRISC port

Dear all,

this is my first attempt to submit my OpenRISC port which I developed 
here: https://github.com/wallento/or1k-newlib
Due to the list's message size restrictions I cannot attach the patches:

   - 
https://raw.githubusercontent.com/wallento/or1k-newlib/for-upstream-2014-12-10/0001-OpenRISC-Add-no-delay-slot-support.patch

   - 
https://raw.githubusercontent.com/wallento/or1k-newlib/for-upstream-2014-12-10/0002-libgloss-OpenRISC-support.patch

   - 
https://raw.githubusercontent.com/wallento/or1k-newlib/for-upstream-2014-12-10/0003-newlib-OpenRISC-Baremetal-support.patch

The port is based on the never-upstreamed port maintained by the 
OpenRISC community. This one was unfortunately GPL and I corresponded 
with all authors in the final port to change the license to BSD.

The port is twofold: A rather large libgloss that contains a lot of 
baremetal support functions to handle exceptions, interrupts, etc. 
easily. Beside this, I added a sys folder for the or1k-elf target that 
uses dynamic reentrancy and depends on libgloss. The machine folder is 
still compatible with the or1k-rtems toolchain. I am really not sure if 
this is the way to go, so please comment on other ways.

The port already contains multicore support with a shared heap and 
private stacks, reentrancy data structures and port internal data 
structures.

[PATCH, AArch64]: Fix register allocation in strchrnul.S

Ooop!  I accidentally used a callee-saved register in the implementation
of strchrnul for AArch64.  Fortunately, the fix is trivial:

	* libc/machine/aarch64/strchrnul.S (vrepmask): Use a call-clobbered

Committed.

stdio_ext.h function implementations

Currently, the bulk of the <stdio_ext.h> functions[1][2] are implemented 
as inline code, or macros on non-gcc-compatible toolchains.  However, 
there are a few issues with that:

* Header-only implementations result in false negatives from 
AC_CHECK_FUNC tests and the like.  For instance, cpio FTBFS on Cygwin 
currently because it tries to implement a replacement for a "missing" 
__fpending which conflicts with the one already in <stdio_ext.h>.

* The Solaris and Linux documentation indicates that at least some, if 
not all, of these functions are thread-safe.  Does the current 
implementation suffice for that, or do these need to be real functions 
wrapped in _newlib_flockfile_{start,end} calls?

* Macro implementations of libc functions need to be undef'ed and backed 
by real functions with C++ (otherwise you get syntax errors in the 
::func form).  Are the inline implementations used by GCC safe for these 
purposes?

* No documentation is generated for these functions.

In any case, for the first point alone, we need real code 
implementations of these functions.  I am prepared to make a patch for 
this, but exactly how depends on the second and third points above.
