Authentication-results: sourceware.org; auth=none

Hi All,

Here is 1-line patch which allows to vectorize shift by inductive
variable for targets supporting vector/vector shift. Test-case is
attached.

Bootstrap and regression testing did not show new failures.
Is it OK for trunk?

ChangeLog:
2015-08-11  Yuri Rumyantsev  <ysrumyan@gmail.com>

* tree-vect-stmts.c (vectorizable_shift): Add missed test on
vect_induction_def.

gcc/testsuite/ChangeLog:
* gcc.target/i386/avx2-vect-shift.c: New test.

Attachment: patch
Description: Binary data
