This patch adds semihosting support for Nios II plus startup code and a 
linker script for bare-board emulation with QEMU.  The QEMU side of 
things requires this patch set

http://lists.nongnu.org/archive/html/qemu-devel/2018-05/msg04571.html

The semihosting code is pretty much a direct copy of the m68k 
implementation, which was contributed by CodeSourcery years ago.  We've 
been using this protocol in our toolchain distributions for Nios II for 
some years now (plus other targets we've been asked to produce 
toolchains for that don't already have some other semihosting protocol 
supported by other tools).

Hi Sandra,

would you mind to send the patch in git format-patch format?
We don't use CVS anymore for quite some time.


Thanks,
Corinna

I looked on the newlib web site before posting and didn't see any 
detailed requirements for patch submission.  If the "git diff" output I 
sent isn't adequate, can you give an exact recipe, and publish it 
somewhere that people can find it before submitting a patch?

Well, just git format-patch and then send it with git send-email is all.
Alternatively as attachment, nothing complicated.

How's this?  (In fact, this is identical to the patch I sent previously, 
except for the bit of header stuff tacked on to it.)
