Hi!
When doing the last cp_genericize_r change, I've noticed most of the

Hi,
Add support for early expansion of vector shifts. Including
vec_sl (shift left), vec_sr (shift right),
vec_sra (shift right algebraic), vec_rl (rotate left).
Part of this includes adding the vector shift right instructions to
the list of those instructions having an unsigned second argument.

Thank you for your help. I fixed the test similar to existing sigaction tests.
gcc/
* config/i386/i386.c: Fix rounding expand for new pattern.
* config/i386/subst.md: Fix pattern (parallel -> unspec).
gcc/testsuite/
* gcc.target/i386/pr73350-2.c: New test.
Thanks,
Julia

this patch has been posted before, but hasn't really been reviewed yet:
https://gcc.gnu.org/ml/gcc-patches/2016-08/msg01927.html

Thanks,
Chung-Lin
