This is workaround to not emit instructions that are broken with current version of QEMU used in CI job. Fixes SIGBUS on valid code when executed in QEMU caused by issue with CVTPS2PD instruction. QEMU issue: https://gitlab.com/qemu-project/qemu/-/issues/1377 QEMU fix: https://gitlab.com/qemu-project/qemu/-/commit/abd41884c530aa025ada253bf1a5bd0c2b808219 Should be resolved after QEMU update to 8.2.0: cross-platform-actions/action#78

Yes. We tried to update to QEMU 8.1, but that broke OpenBSD. Hopefully 8.2 works better. |

We use QEMU emulation for stability, because xhyve hypervisor was failing half of the time last time we tried it. I've seen in recent release notes that there seems to be mitigation in place, so we might revisit that, but that's for another day.
For now I would like to request QEMU update to latest stable (8.2.0) as recently we hit the code which crashes QEMU. We get SIGBUS on valid code, see https://github.com/mpv-player/mpv/actions/runs/7377653152/job/20071858642
After painful debugging, because I couldn't reproduce locally, it seems to be CVTPS2PD instruction that fails. And sure enough after quick search the issue we see likely has been fixed in the recent stable release of QEMU (8.2.0)
