Compilers

This post was originally written on Codeforces; relevant discussion can be found here. As of May 2024, the bug has been fixed in GCC 14, but has not been ported to Codeforces yet.

Namely, any pragma that is of the form #pragma GCC target(...) would NOT work with this new compiler. The issue is well-known by people who use up-to-date compilers but there has not been much progress towards a fix. ...

This post was initially meant to request updates to the C compiler on Codeforces (given the large number of posts complaining about “mysterious” issues in their submissions in C). While writing it, I realized that the chances of the said updates would be higher if I mentioned a few reasons why people would like to code in C instead of C++ (some of the reasons are not completely serious, as should be evident from the context). ...

However, I believe many of them don’t fully understand what they’re doing or how pragmas work; the only thing people seem to think is that “add pragmas -> code go brr”. ...
