I lost a bit the overview, but I think the following still needs to be done:
- 4.4/4.5/4.6: Backporting the fix for nonpresent actuals to elemental procs,
cf. commit in comment 5 / comment 6. That is a true [4.4-4.6] regression
- 4.6: Backporting for the fix for unallocated/unassociated variables to
elemental procedures. That's not a true regression.
- The test case of comment 13 / attachment 26291
with the test-case corrections of comment 22
This test case still fails. There are some draft patches for that in this PR.
- The test case of comment 23 / attachment 26392
"sub_ctae" is invalid in needs to be removed. The test case compiles without
any problems, but the program segfaults at run time for:
call sub_ct(var1)
call sub_ct(var2)
if the variables aren't allocated. That seems to be the same issue as
comment 31. Namely: The present() check does not work for CLASS.
- For the following, a test case should be written, tested, and included
in the test suite (partially covered by the tests above):
OPTIONAL dummy argument:
- actual argument not present (i.e. compiler added null), "NULL()",
nonallocated actual, nonassociated actual. But also: Actual present.
- Actual argument a scalar or an array
- Actual argument CLASS or TYPE
- Actual argument a variable or a derived-type component
Dummy argument: CLASS or TYPE
ELEMENTAL procedure with scalar
or nonelemental with (scalar or) array dummy argument.
For passing a CLASS actual to a TYPE dummy, see also PR 51514.
