            Bug ID: 70729
           Summary: Loop marked with omp simd pragma is not vectorized
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ysrumyan at gmail dot com
  Target Milestone: ---

Analyzing performance of one important benchmark we found out that one of the
hot loop is no vectorized since loop-invariant load of the class member has not
been hoisted out of loop although loop was marked with omp simd pragma.
Test-case  to reproduce is attached.
