If it was previously enabled on 32-bit and was possible to successfully build & use, then it needs to go through the deprecation process - we can't just rip out features with no prior warning. In any case this recently merged: commit 6d701c9bac1d3571e9ad511e01b27df7237f0b13 Author: Richard Henderson Date: Mon Jan 27 16:22:24 2025 -0800 meson: Deprecate 32-bit host support We deprecated i686 system mode support for qemu 8.0. However, to make real cleanups to TCG we need to deprecate all 32-bit hosts. so 32-bit host support in general is nearing end of life. Given that, I don't think we need to further limit 32-bit host for individual features, just let it die all at once.
