When running the libgomp testsuite on x86_64 with nvptx accelerator, we run into:
...
XPASS: libgomp.c/../libgomp.c-c++-common/pr96390.c (test for excess errors)
FAIL: libgomp.c/../libgomp.c-c++-common/pr96390.c execution test
...
The problem is that we're expecting the following ptxas error:
...
XFAIL: libgomp.c/../libgomp.c-c++-common/pr96390.c (test for excess errors)
Excess errors:
ptxas /tmp/ccZYDw8N.o, line 90; error : Call to 'baz' requires call prototype
ptxas /tmp/ccZYDw8N.o, line 90; error : Unknown symbol 'baz'
...
But it's not triggered because ptxas is not in the path, so nvptx-none-as
defaults to --no-verify.
So instead, we run into the same error at execution time.
Fix this by forcing verification using:
...
/* { dg-additional-options "-foffload=-Wa,--verify" \
{ target offload_target_nvptx } } */
...
such that we run into the xfail in this way instead:
...
XFAIL: libgomp.c/../libgomp.c-c++-common/pr96390.c (test for excess errors)
Excess errors:
nvptx-as: error trying to exec 'ptxas': execvp: No such file or directory
nvptx-as: ptxas returned 255 exit status
...
Tested on x86_64-linux with nvptx accelerator.
