This adds -std=f2023, which is mostly a prep patch for future changes.
However, Fortran 2023, https://j3-fortran.org/doc/year/23/23-007r1.pdf
changes two things which is taken
care in this patch:
(A) In "6.3.2.1 Free form line length":
Fortran 2018: "If a line consists entirely of characters of default kind
(7.4.4), it shall contain at most 132 characters"
Fortran 2023: "A line shall contain at most ten thousand characters."
(B) In "6.3.2.6 Free form statements":
Fortran 2018: "A statement shall not have more than 255 continuation
lines."
Fortran 2023: "A statement shall not have more than one million
characters."
I have not added a testcase for exceeding the latter but otherwise there
are new
tests and I had to add a couple of -std=f2018 to existing tests.
Comments, suggestions, approval?
My only comment is that the Standards Committee seems to have no idea of
actual good coding practices. I have to assume they want this so people
can have very very long DATA statements or array constructors or some
such nonsense.
I always thought data files were for these sorts of things. The software
engineers I work with would roll there eyes and say, "Hey you users out
there, stop asking the compiler writers to fix your code for you by
changing the compiler. Do your code correctly in the first place"
Perhaps AI is being used to generate the source files?
Cheers,
