Issue #21371 has been reported by ioquatix (Samuel Williams). ---------------------------------------- Bug #21371: Proposal to Remove SPARC Architecture Support from Ruby https://bugs.ruby-lang.org/issues/21371 * Author: ioquatix (Samuel Williams) * Status: Open * Assignee: ioquatix (Samuel Williams) * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- 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/
