            Bug ID: 65460
           Summary: parloops transforms offloaded functions
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vries at gcc dot gnu.org

The offload variant of PR65458 - parloops transforms omp-thread functions.

AFAIU, running the parloops pass on the host version of offloaded functions,
may as well speed up as degrade performance. 

It's probably best to disable parloops for offloaded functions, at least until
we do a targeted exercise to speed up host execution of offloaded functions.
