I've filed PR99555 "[OpenMP/nvptx] Execution-time hang for simple nested OpenMP
'target'/'parallel'/'task' constructs".
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98738
--- Comment #16 from Thomas Schwinge ---
Ugh. :-( Where are we tracking this, and is anyone working on this? It's
clearly not useful to have (nvptx offloading) testing to run into known
TIMEOUTs?

--- Comment #10 from Jakub Jelinek ---
I've been wondering whether it wouldn't be best to pass through
omp_eventhandle_t the pointer to the gomp_task rather than some particular
semaphore and in omp_fulfill_event then decide based on that task,
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98738
--- Comment #9 from Kwok Yeung ---
I have a patch for this now. In addition to posting other semaphores in
omp_fulfill_event, GOMP_taskwait also needs to be made aware of detached tasks.
Also, task_running_count should not include completed tasks
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98738
--- Comment #8 from Jakub Jelinek ---
I think omp_fullfill_event needs to do much more than it does.
Just look e.g. at what gomp_target_task_completion does. The function needs to
find out in what state the task is (I'm afraid it needs to take t

--- Comment #7 from Jakub Jelinek ---
Seems making task_fulfilled_p return always false makes the task-detach-6.c
hangs 100% reproduceable.

--- Comment #6 from Kwok Yeung ---
It seems to be the '#pragma omp taskwait' inside the parallel region that is
causing the intermittent hang - if you add it to task-detach-5.c, the hang also
happens there (i.e. the target construct is not the pr

--- Comment #5 from Jakub Jelinek ---
At least the
firstprivate(detach_event1, detach_event2)
on parallel look incorrect, the vars are uninitialized at that point, so
copying those copies uninitialized values.

I realized I didn't post the command line I used to build task-detach-6.exe
(there are multiple variants of this test); here it is:
gcc/build/x86_64-pc-linux-gnu/libgomp/testsuite$ ../../../../build/./gcc
