I ran into similar issues with glibc test suite. It seems gcc 7.x released won't 
cut it - it misses tons of upstream patches including

2017-11-03 e892f4fac605 [ARC] Fix to unwinding.
  

So your best bet is to use upstream gcc master !

gcc 7 branch or gcc 8 latest greatest?

Last time there was some issue with gcc8 and you told me to use gcc7
with some patches.

/me is confused.

AFAIK gcc 8 is not released yet, so upstream/master !

Right there was yet another code gen issue / ICE at the time, which is likely gone 
now. But gcc upstream/master works for me.

Sorry if I steered you the wrong way. At that time upstream was practically not 
usable, so more unwinder tests failing were kind of secondary on priority ;-)

Now I have again the original ICE with gcc upstream/master as
reported last time. What's wrong with my setup?

Could you please elaborate a bit on how do you build ARC toolchain?
That way we'll try to reproduce your problem locally.

Also may I ask you to try the very latest GCC and Binutils from 

GCC: https://github.com/foss-for-synopsys-dwc-arc-processors/gcc/tree/dev
Binutils: https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/tree/arc-2018.03

With these sources I can build everything successfully and run entire test-suite
with that following results:
-------------->8------------
Total skipped: 15
Total failed: 19
Total passed: 397
-------------->8------------

Yes, that are the results I get when using the synopsys sources.
My idea is to forecast the results with upstream binutils and gcc in
the hope everything will be fine when gcc8 and binutils 2.31 is
released.

Here is the full log using binutils/gcc git master:

[Claudiu Zissulescu]

Hi Waldemar,

The GCC master branch can be broken from time to time, and this is the reason why we get a snapshot in our Synopsys git account for testing and stability. But once we get the gcc 8.x release, this shouldn't be the case, and you can use the official release with maybe some 1-2 extra patches on top. 
As for Binutils mainline master version, we discovered a number of issues which needs to be addressed on our side. The good news is we have patches which we are testing them right now, and I expect those patches to be quickly send to binutils mailing list and integrated once we have the confidence we brake nothing extra:)

Cheers,
Claudiu
