Bug ID: 81378
Summary: [nvptx] Add openacc testcase using generated ptx but
bypassing libgomp
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: libgomp
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
CC: jakub at gcc dot gnu.org
Target Milestone: ---
An openacc test-case uses libgomp and the libgomp nvptx plugin to offload ptx
code to a cuda device.
When reporting ptx bugs to nvidia, we send standalone test-cases that do not
use libgomp. These test-cases use a harness.c that, not surprisingly, contains
a lot of code from libgomp/plugin/plugin-nvptx.c.
It would be good to add harness.c to libgomp, factor out the common code into a
reusable form, and add a test-case that:
- compiles and runs an openacc test-case
- extracts the ptx
- uses the harness.c to compile and run the ptx, in the same way as the plugin
would do
