--- Comment #1 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
Thanks for the report, I'll have a look (next month).

Probably not since it was originally added in commit
d5c23c6ceacf666f218676b648801379044e326a 'OpenACC – support "if" + "if_present"
clauses with "host_data"', but rather in my more recentish commit
11b8286a83289f5b54e813f14ff56d730c3f3185 "[OpenACC privatization] Largely
extend diagnostics and corresponding testsuite coverage [PR90115]".  (Or, if it
indeed has been FAILing before, then it must be a different problem.)

Please do tell if there are further such "[is/isn't] candidate for adjusting
OpenACC privatization level" diagnostic mismatches (excess errors, or FAILs),
in other testcases.  (But indeed per a quick scan of
<gcc-testresults@gcc.gnu.org> posts, it's just
'libgomp.oacc-c-c++-common/host_data-7.c', and it PASSed before my
"diagnostics" commit.)

Right, I didn't look closely enough.  In fact, the test is PASSing on the
gcc-11 branch,so this is even a regression.

Besides, it affects Solaris/SPARC and x86 alike, so is not x86-specific.

No, this is the only instance.

--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> ---
The master branch has been updated by Thomas Schwinge <tschwinge@gcc.gnu.org>:

https://gcc.gnu.org/g:ab46fc7c3bf01337ea4554f08f4f6b0be8173557

commit r12-7663-gab46fc7c3bf01337ea4554f08f4f6b0be8173557
Author: Thomas Schwinge <thomas@codesourcery.com>
Date:   Wed Mar 16 08:02:39 2022 +0100

    OpenACC privatization diagnostics vs. 'assert' [PR102841]

    It's an orthogonal concern why these diagnostics do appear at all for
    non-offloaded OpenACC constructs (where they're not relevant at all);
PR90115.

    Depending on how 'assert' is implemented, it may cause temporaries to be
    created, and/or may lower into 'COND_EXPR's, and
    'gcc/gimplify.cc:gimplify_cond_expr' uses 'create_tmp_var (type, "iftmp")'.

    Fix-up for commit 11b8286a83289f5b54e813f14ff56d730c3f3185
    "[OpenACC privatization] Largely extend diagnostics and
    corresponding testsuite coverage [PR90115]".

Can't (easily) test due to corresponding Solaris/Darwin system
non-availability, but I think I understand the issue, and it should now be
fixed.  Please re-open if not.

Also putting Iain in CC, who for Darwin configurations also has a lot of
<gcc-testresults@gcc.gnu.org> reports for this:

The failures are gone in last night's i386-pc-solaris2.11 and
sparc-sun-solaris2.11 bootstraps.  Thanks.
