Hi,
On a GT 1030, with driver version 470.94 and -mptx=3.1 I run into:
...
FAIL: libgomp.oacc-c/../libgomp.oacc-c-c++-common/parallel-dims.c \
-DACC_DEVICE_TYPE_nvidia=1 -DACC_MEM_SHARED=0 -foffload=nvptx-none \
-O2 execution test
...
This relates to PR99932 "OpenACC/nvptx offloading execution regressions
starting with CUDA 11.2-era Nvidia Driver 460.27.04". You've fixed that
for GCC 12+, but testing nvptx offloading for GCC 11, GCC 10 branches on
a system with current Nvidia Driver, we're still running into the several
FAILs and annoying 'WARNING: program timed out' reported in PR99932.
GCC 11, GCC 10 only build '.version 3.1' target libraries, and with
"[nvptx] Add bar.warp.sync" in place (which this patch here thus only
textually depends on), we've got good test results again.
OK to push to GCC 11, GCC 10 branches the attached
"[nvptx] Add uniform_warp_check insn"?
LGTM.
Thanks,
