Hi all,
I had this weird issue yesterday, a build I did in the morning
skipped the OpenCL tests, with this in gdb.log:
...
skip_opencl_tests: OpenCL support not detected
UNSUPPORTED: gdb.opencl/callfuncs.exp: OpenCL support not detected
testcase ... /gdb.opencl/callfuncs.exp completed in 1 seconds
But! A build I did in the afternoon got past that:
...
skip_opencl_tests: OpenCL support detected
Downloading on target to callfuncs.cl:...
...
UNTESTED: gdb.opencl/callfuncs.exp: failed to compile
testcase ... /gdb.opencl/callfuncs.exp completed in 2 seconds
But, now, if I re-run that test, in the directory OpenCL support was
detected, it fails with the first failure above.
The two test runs were slightly different versions of gdb (I did a
"git pull" before each), and some of Andrew Burgess's commits
mention opencl... but, if something changed there, why would it
revert to non-detection when I re-run the test?
I'll paste fuller logs for one of the opencl testcases below.
Please help!
Cheers,
Gary
