[J3] [EXTERNAL] [BULK] Re: Upcoming gfortran 15 will contain an implementation of unsigned numbers

[Malcolm Cohen]

Hi Tom,

 

Yes, it passed to be put on the USA list of proposals to give to WG5. Otherwise WG5 would not even have considered it. Every proposal that WG5 considered and rejected, for every Fortran standard revision, *passed* some country’s committee vote to put it on the list. (And usually J3, since the USA traditionally submits the most proposals by far.)

 

So that is not a twist, just the normal procedure.

 

Cheers,

The history of this feature  has a twist.   There was a paper proposing this feature for F202y and it *passed*.   However, it did not garner the necessary votes to make it onto the proverbial bus for the WG5 list.

 

Close, but no cigar.

Someone has said unsigned integers are planned for F202Y. I don’t know where they got that idea. I’m too nervous to post on forums, but if someone else thinks it would useful to post a correction, I wouldn’t be opposed!

 

Thanks,

Aury

Hi Jeff,

I strongly encourage gfortran to issue a warning when this option is used that the code is not portable.


It is hidden behind a flag which is marked as experimental, that is enough.
I will certainly not issue a warning for using the -funsigned flag :-)

If people find it useful... well, if it should happen to become a
widely-used extension, that could add some impetus towards
adding it for F203X.

Best regards

    Thomas
