--- Comment #3 from Andrew Stubbs <ams at gcc dot gnu.org> ---
That output shows that we have the correct libgomp and rocm is installed and
working. Libgomp initialized the GCN plugin, but did not attempt to initialize
the device (the next message in the output should have been "Selected kernel
arguments memory region", or at least a GCN error message).
Instead we have a target-independent libgomp error. Presumably the kernel
metadata is malformed, somehow?
I think we need a testcase to debug this further, preferably reduced to be as
simple as possible.
Perhaps it would be a good idea to start with a minimal toy example and see if
that works on the device.
#include <openacc.h>
#include <stdio.h>
int main ()
{
int v = 1;
#pragma acc parallel copy(v)
{
if (acc_on_device(acc_device_host))
v = -1; // error
else {
v = 2; // success
}
}
printf ("v is %d\n", v);
return v;
}
