Bug ID: 100497
Summary: [OpenMP][nvptx] libgomp.c-c++-common/reduction-5.c -
fails on some nvptx systems
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: openmp, wrong-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
CC: vries at gcc dot gnu.org
Target Milestone: ---
The two testcases
libgomp.c-c++-common/reduction-5.c
libgomp.c-c++-common/reduction-6.c
fail on some nvptx systems. (Added in
r12-614-g33b647956caa977d1ae489f9baed9cef70b4f382 )
The problem are the 'teams' versions with complex arguments; the non-teams ones
do work - the problem is that the complex variables are '0 + 0i' instead of '1
+ 0i' - hence, those tests which expect 0 also pass.
For some reason, it fails on half of the tested systems but not on the other
half. The PASS/FAIL are consistent; it does not seem to depend on the CUDA
version, it might depend on the used hardware or it might work only by chance
due to the way the partitioning is done.
