Hello All,
I was mulling over the F2018 status of gfortran, when I came across the
additions to the IMPORT statement. This seemed like such a useful
addition to fortran that I set about an implementation; thinking that
this would be low hanging fruit. Parsing and checking the
constraints C897-8100 turned out to be straightforward. C8101 was
already implemented for F2008 IMPORT. C8102 required a lot more work!
(Please see the patch for the constraints.)
Steve K got in touch, when he found out that we had been working in
parallel on the new IMPORT features. Thus encouraged by our exchanges, I
ground on until the patch reached its present state. I think that the
ChangeLog is clear enough, even if the patch came out a bit long winded.
Of the existing IMPORT tests, only import3.f90 needed modification by
setting -std=f2008 because of the change in the wording of the error
messages. The new test, import12.f90, is complete IMHO but I am open to
suggestions for additions. I cannot return to working on this until the
second week of July so you have plenty of time to test and comment.
Regtests fine with x86_64 on FC42. OK for mainline?
Paul
I do think the new test case is very thorough. I reviewed that patch for
anything glaring and it looks good. I also tried it on some things here
and got what I expected.
If you and Steve have been in touch I think it is OK for mainline.
Cheers,
Jerry
