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.
