Still having trouble reproducing the issue. I don't have an arch system so I used Docker. Would you be willing to check whether the Dockerfile represents a close enough match to your build process?
Also, if you can think of anything particularly unique about your configuration, maybe I can try to come closer to reproducing this with some of those critical factors. ** Attachment added: "Dockerfile" https://bugs.launchpad.net/qemu/+bug/1916394/+attachment/5472325/+files/Dockerfile -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1916394 Title: [git] Cannot build qemu: FAILED: target/hexagon/semantics_generated.pyinc Status in QEMU: New Bug description: Hello.
