Issue #19353 has been updated by jeremyevans0 (Jeremy Evans).

The sparc64 backend for clang is not yet mature (last I checked), so this would make it so Ruby 3.3+ would be unlikely to be supported on OpenBSD/sparc64 (at least, until the clang sparc64 backend matures).  I would like to keep support for gcc 4.2.1 if possible, but I certainly understand if support has to be dropped.

Since writing this, we've found out that we can compile Ruby 3.2 on OpenBSD/sparc64 using the system compiler (gcc 4.2.1), but compiling gems with C extensions fails with the system compiler and we have to use an ports compiler (gcc 8.x I think).  This wasn't the case for Ruby 3.1. Considering this, I withdraw my objection to dropping gcc < 6 support, since we can switch to compiling Ruby itself with the ports compiler on OpenBSD/sparc64.

We test those old compilers using Ubuntu bionic. This OS is reaching its EOL.
Making them available would become harder.

I would like to drop supporting them.  Any opinions?
