Bug ID: 67822
Summary: OpenMP offloading to nvptx fails
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Keywords: openmp
Severity: enhancement
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: tschwinge at gcc dot gnu.org
Target Milestone: ---
When nvptx offloading linking is enabled (but that just exposes the problem,
doesn't cause it), we see lot of OpenMP offloading test cases fail as follows,
for example, libgomp/testsuite/libgomp.c/examples-4/async_target-1.c:
ptxas /tmp/ccwcheo3.o, line 117; error : Instruction 'kernel function
address' requires .target sm_35 or higher
ptxas fatal : Ptx assembly aborted due to errors
nvptx-as: ptxas returned 255 exit status
mkoffload: fatal error:
[...]/build-gcc/gcc/x86_64-pc-linux-gnu-accel-nvptx-none-gcc returned 1 exit
status
