Bug ID: 78266
Summary: broken openacc loop partitioning on nvptx offloading
targets
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Keywords: openacc
Severity: normal
Priority: P3
Component: middle-end

vprop.c
The attached test case demonstrates a situation where an acc 'gang worker'
partitioned loop encloses an acc vector partitioned loop fails to generate
correct code. I'm not sure if there is a problem in the nvptx backend
worker-state propagator, or if oaccdevlow is generating bad code.
This test case works fine if the outer loop is either gang or worker
partitioned, but not both.
