* [Patch] Fortran: Accept -std=f2023 support, update line-length for Fortran 2023 @ 2023-11-16 13:01 Tobias Burnus 2023-11-16 19:30 ` Harald Anlauf 2023-11-17 3:38 ` [Patch] Fortran: Accept -std=f2023 support, " Jerry D 0 siblings, 2 replies; 9+ messages in thread From: Tobias Burnus @ 2023-11-16 13:01 UTC (permalink / raw) To: gcc-patches, fortran [-- Attachment #1: Type: text/plain, Size: 1306 bytes --] 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? Tobias PS: I find it funny that -std=c23, -std=c++23 and -std=f2023 will get added in the same GCC release. PPS: I did not bother adding .f23 as file extension; I believe that also .f18 is unsupported. ----------------- Siemens Electronic Design Automation GmbH; Anschrift: Arnulfstraße 201, 80634 München; Gesellschaft mit beschränkter Haftung; Geschäftsführer: Thomas Heurung, Frank Thürauf; Sitz der Gesellschaft: München; Registergericht München, HRB 106955 [-- Attachment #2: std-f2023.diff --] [-- Type: text/x-patch, Size: 152253 bytes --] Fortran: Accept -std=f2023 support, update line-length for Fortran 2023 This patch accepts -std=f2023, uses it by default and bumps for the free-source form the line length to 10,000 and the statement length alias number of continuation lines to unlimited. gcc/fortran/ChangeLog: * gfortran.texi (_gfortran_set_options): Document GFC_STD_F2023. * invoke.texi (std,pedantic,Wampersand,Wtabs): Add -std=2023. * lang.opt (std=f2023): Add. * libgfortran.h (GFC_STD_F2023, GFC_STD_OPT_F23): Add. * options.cc (set_default_std_flags): Add GFC_STD_F2023.

According to the standard one can have 999999 lines with only "&" and then an ";", but then only 100 lines with 10000 characters. There is a similar wording for fixed-form which you overlooked: 6.3.3.5 Fixed form statements Fortran 2023: "A statement shall not have more than one million characters" Please adjust the fixed-form limits in your patch. If you think that we need testcases for fixed-form, add them, or forget them.

I have the following comments: - there are existing testcases continuation_5.f, continuation_6.f, thus I suggest to rename your new continuation_{5,6}.f90 to continuation_17.f90+ . - I don't understand your new testcase line_length_14.f90 . This is supposed to test -std=gnu, but then -std=gnu is not a standard but a moving target, which is why you had to adjust existing testcases. So what does it buy us beyond line_length_1{2,3}.f90 ? > Tobias > > PS: I find it funny that -std=c23, -std=c++23 and -std=f2023 will get > added in the same GCC release. :-) > PPS: I did not bother adding .f23 as file extension; I believe that also > .f18 is unsupported. I never use extensions other than .f90 for portable code. With the above fixed, I am fine with your patch.

I can confirm this. I tried to get it working in scanner.cc but due to the re-parsing it is quite difficult to get it right; the main problem is that we keep reparsing code ("gfc_current_locus = old_loc"), such that a simple count will be wrong. → Now tracked at https://gcc.gnu.org/PR112586 > According to the standard one can have 999999 lines with only > "&" and then an ";", but then only 100 lines with 10000 characters. I believe a single '&' is not valid, you either need '&&' or something else + '&'; thus, you can have only half a million lines + 1. In the code, I still use 1,000,000 but now with a comment. > There is a similar wording for fixed-form which you overlooked: Ups - fixed. > If you think that we need testcases for fixed-form, add them, > or forget them.

We are rather inconsistent whether we enumerate <file>.f{,90} together or separately; as the suffix is shown, either works. > > - I don't understand your new testcase line_length_14.f90 . > This is supposed to test -std=gnu, but then -std=gnu is not a > standard but a moving target, which is why you had to adjust > existing testcases. > So what does it buy us beyond line_length_1{2,3}.f90 ? Well, it ensures that the warning is not only shown for -std=f2023 but also for -std=f2028 and (current -std=gnu). In general, I think it is useful to check the lower and the upper bound. I have now removed it - as it is unlikely that we would regress on such changes. >> PPS: I did not bother adding .f23 as file extension; I believe that also >> .f18 is unsupported. > I never use extensions other than .f90 for portable code. Likewise - especially as '.f95' starts out as Fortran code that complies to -std=f95 but slowly Fortran 2003 or later code creeps in. I think that's fine but then one can also directly use .f90. (Most code does so.) Unless there are follow up comments, I will commit it later today. Thanks for the comments! Tobias PS: I fixed the wording issue in the subject line of the email and header. I first wrote 'support' but that sounded a bit as if F2023 is supported. Hence, I wrote 'Accept' and did not remove 'support'. ----------------- Siemens Electronic Design Automation GmbH; Anschrift: Arnulfstraße 201, 80634 München; Gesellschaft mit beschränkter Haftung; Geschäftsführer: Thomas Heurung, Frank Thürauf; Sitz der Gesellschaft: München; Registergericht München, HRB 106955 [-- Attachment #2: std-f2023-v3.diff --] [-- Type: text/x-patch, Size: 115483 bytes --] Fortran: Accept -std=f2023, update line-length for Fortran 2023 This patch accepts -std=f2023, uses it by default and bumps for the free-source form the line length to 10,000 and the statement length alias number of continuation lines to unlimited. gcc/fortran/ChangeLog: * gfortran.texi (_gfortran_set_options): Document GFC_STD_F2023. * invoke.texi (std,pedantic,Wampersand,Wtabs): Add -std=2023. * lang.opt (std=f2023): Add. * libgfortran.h (GFC_STD_F2023, GFC_STD_OPT_F23): Add. * options.cc (set_default_std_flags): Add GFC_STD_F2023.

You are right: a single '&' is not valid. 6.3.2.4 also has: "When used for continuation, the “&” is not part of the statement" And 6.3.2.5 (also 6.3.3.4): "The “;” is not part of the statement". So a million "&"-continued lines is possible in free form. For fixed form, 6.3.3.1 has: "If a source line contains only characters of default kind, it shall contain exactly 72 characters; otherwise, its maximum number of characters is processor dependent." I wonder what I should make out of this... > In the code, I still use 1,000,000 but now with a comment. Yeah, for the time being this is the most reasonable solution. Let's claim that the 10^6 line limit is the new GNU standard ;-) Cheers, Harald ^ permalink raw reply [flat|nested] 9+ messages in thread

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, Jerry ^ permalink raw reply [flat|nested] 9+ messages in thread
