Subject: RE: Why does GDB currently still supports only the features of Fortran 77 language?

Hi,
the documentation for the Fortran part of GDB is a bit outdated. It is not actually
true that GDB only supports Fortran 77 features - there is newer features that are
supported, too. Though there probably is not a standard (90/95..) for which one
could say that all Fortran features are fully supported (except maybe 77 though here
I am not sure).
GDB as of yet does not support every language feature of the latest standards.
As for the reason - GDB is a collaborative project that relies on contributions and
probably no one has come around doing the necessary work yet.
If you find that there is a specific feature missing, I would suggest opening a
'Feature request' bug for GDB at https://sourceware.org/bugzilla/ . Or, you could
become contributor yourself, too.
There is this patch I just sent that tries to improve the Fortran documentation a bit
https://sourceware.org/pipermail/gdb-patches/2022-April/187710.html
It describes all currently supported Fortran intrinsics.
Best regards,
Nils
