I really appreciate if you could spend some time take a look at the following

Hi all,
Would love some feedback on this patch!

I saw that files such as /tmp/ccxFKYeS.target.o kept accumulating. Not a high
number,
but still several.
I turned out that when compiling an offloading program successfully, they were
removed.
But when it failed, those remained. (Example: See PR.)
This patch fixes this by storing the file name

Rather obvious, once found. I forgot to add some cleanup, cluttering
/tmp with ".mkoffload.omp_requires".
The same issue exists for GCN also for ".mkoffload.dbg"
OK for mainline? – For the dbg issue, OK also for GCC 11 and 12 backport?

The following avoids adding PHIs to the worklist for uninit processing
if we reach them following backedges. That confuses predicate analysis
because it assumes the use is happening in the same iteration as the the
definition. For the testcase in the PR the situation is like
void foo (int val)

I think we can make -mcmodel=large imply -fno-plt, and reject if user

Because may_be (nunits, 1) return true. For nunits = (1,1), it will execute
test_vector_subregs_modes.

Ah, right, sorry for the bogus sug
Hi, Richard. I tried the codes:
if (!nunits.is_constant () && maybe_gt (nunits, 1))
test_vector_subregs_modes (x, nunits - min_nunits, count);
It still failed. For nunits = (1,1) , maybe_gt (nunits, 1) return true value.

Thank you so much. Address your comment. I think "maybe_gt (nunits, 1)" is a
more solid solution than I do.
I will send a patch to fix this.
