From: "kddnewton (Kevin Newton) via ruby-core" Date: 2024-01-08T14:59:21+00:00 Subject: [ruby-core:116070] [Ruby master Misc#20156] C99 updates Issue #20156 has been updated by kddnewton (Kevin Newton). I was going based on https://github.com/ruby/ruby/wiki/C99-Usage-Guidelines. Maybe this documentation needs to be updated. > b75828fdfadaff6c5e09e42be32dff1216ed8fb1 says: >> Fix compile error with Oracle Solaris Studio 12.4 on Solaris 10. > No problem with Oracle SS 12.5? The title of that commit is `Support C89 if possible`. @ngoto was that necessary for actual C99 compilers or only to support old out-of-date compilers? > _MSC_VER 1800 seems VS2013, so we might have been able to drop this condition already. Yes I think this is true. > We use our custom snprintf not only for old platforms, but also to avoid locales. I see, thanks for the clarification. ---------------------------------------- Misc #20156: C99 updates https://bugs.ruby-lang.org/issues/20156#change-106068 * Author: kddnewton (Kevin Newton) * Status: Open * Priority: Normal ---------------------------------------- Now that we require Visual Studio 2015 and Oracle Developer Studio 12.5, we can do a couple of things to clean up: * We should be able to remove our custom `stdbool.h` (added in VS2015 and Oracle SS 12.3) * Remove our usage of `__restrict` for Windows (added in VS2015) * Remove our custom `va_copy` (added in VS2015) Just notating, a couple of things that we _can_ use now: * snprintf * size_t printf format specifier (%z) I'm happy to do this work, but I wanted to open this ticket in case there is something besides Visual Studio or Oracle Solaris Studio that I would have missed for one of our compilation targets. Are there any other targets that do not fully implement C99? -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/postorius/lists/ruby-core.ml.ruby-lang.org/
