Another option is to peel scalar loop and then just run vectorizer
one more time to vectorize and mask it.
Also we may peel vectorized loop and use original version (with all
STMT_VINFO still available) as a tail and peeled version as a main
loop.

Hi Richard,
I re-designed the patch to determine ability of loop masking on fly of
vectorization analysis and invoke it after loop transformation.
Test-case is also provided.
what is your opinion?
Thanks.
Yuri.

Richard,
Thanks a lot for your detailed comments!
Few words about 436.cactusADM gain. The loop which was transformed for
avx2 is very huge and this is the last inner-most loop in routine
Bench_StaggeredLeapfrog2 (StaggeredLeapfrog2.F #366). If you don't
have sources, let me know.
Yuri.

It's on my list - I'm still swamped with patches to review.

Hi Richard,
Here is updated version of the patch which 91) is in sync with trunk
compiler and (2) contains simple cost model to estimate profitability
of scalar epilogue elimination. The part related to vectorization of
loops with small trip count is in process of developing. Note that
implemented

Richard,
It looks like misunderstanding - we assume that for GCCv6 the simple
scheme of remainder will be used through introducing new IV :
https://gcc.gnu.org/ml/gcc-patches/2015-09/msg01435.html
Is it true or we missed something?
Now we are testing vectorization of loops with small non-constant

This is expected failure since this patch is not in sync with the
latest patches related to masking support for AVX512.
I am waiting for support for masking load/store support which is not
integrated to trunk. To get workable version of compiler use revision
before r229128.
