Hi Ilmir!

Yes!  :-) Congratulations, and thanks for promptly addressing the issues
raised during review.  I'm aware this can be a bit of a boring or tedious
process, but in the end, the code quality will be higher (well, that's
the idea about code review), and certainly you'll have learned some
things, too (and I have, too), and so next time this process will likely
be faster.


Only a few minor comments about the ChangeLog formatting:

YYYY-MM-DD is the format used in ChangeLogs.

For multiple authors, do it like this:

2014-02-13  Ilmir Usmanov  <i.usmanov@samsung.com>
	    Dmitry Bocharnikov  <dmitry.b@samsung.com>
	    Evgeny Gavrin  <e.gavrin@samsung.com>

(I don't care, but) you can also do it as follows, a bit simpler:

	* [file] ([item 1], [item 2], [...]): [text].

As the enum omp_clause_code is the thing that you modify, that would be:

	* tree-core.h (enum omp_clause_code): Add OMP_CLAUSE_HOST, [...].

Or, as other people do:

	* tree-core.h (omp_clause_code): Add OMP_CLAUSE_HOST, [...].
