Issue #21371 has been updated by mame (Yusuke Endoh). FYI, Ruby has a Solaris platform maintainer, @ngoto. https://github.com/ruby/ruby/blob/87d340f0e129ecf807e3be35d67fda1ad6f40389/d... He still has access to Solaris/SPARC machines. And he is active enough that he worked on getting Ruby to compile on Solaris just five months ago. https://bugs.ruby-lang.org/issues/20963 ---------------------------------------- Misc #21371: Proposal to Remove SPARC Architecture Support from Ruby https://bugs.ruby-lang.org/issues/21371#change-113435 * Author: ioquatix (Samuel Williams) * Status: Assigned * Assignee: ngoto (Naohisa Goto) ---------------------------------------- We propose removing support for the SPARC architecture from Ruby. SPARC has seen little to no community usage in recent years, and its continued presence in the codebase, particularly through special cases like `rb_sparc_flush_register_windows` adds complexity without clear benefit. Removing SPARC support will reduce maintenance overhead and simplify Ruby’s internals. ## Proposal We propose removing all SPARC-specific code from the Ruby source tree, including `rb_sparc_flush_register_windows` and related build system conditionals. This change would be noted in the release documentation and targeted for inclusion in Ruby 4.0. -- https://bugs.ruby-lang.org/
