Thanks. I see the main problem besides the dumppfx constness is the
double dot before target, fixed in the revised patch below.
With this, I think the libgomp testsuite might work with offloading
again.
Thanks. I have only tried the first one of the list Thomas has sent.
Result as follows – seems to work: PASS :-)

[As previously mentioned, the libgomp OpenACC tests cycle through:
-foffload=nvptx-none + ...=disable plus the -D… defines.
(That build supports neither amdgcn, hsa nor intelmic.)]
and intelmic.
How does intelmic get into the picture?
No idea – I just know that it counts as offloading platform,
ENABLE_OFFLOAD is set for it (but not for has).
I just wanted to mention it GCC supports it, in principle.
(What I have heard is that it does not exist in silicon but
only as simulator, which can be used for testing with GCC,
but I did not follow this at all.)
I looked for a mkoffload
program for it in the GCC source tree and couldn't find one. This
suggests that the addition of -dumpbase to the mkoffload interface might
require changes elsewhere.
Maybe. I think Thomas is the only one who runs GCC with
emulated intelmic once in a while – thus, he surely knows a bit more about it.
But also Jakub should have an idea.
