Hmm scratch that... it fails in a number of linux-user only builds with: /usr/bin/ld: libqemu-aarch64_be-linux-user.fa.p/linux-user_aarch64_cpu_loop.c.o: in function `cpu_loop': /builds/stsquad/qemu/build/../linux-user/aarch64/cpu_loop.c:133: undefined reference to `do_common_semihosting' collect2: error: ld returned 1 exit status [651/2871] Compiling C object libqemu-alpha-linux-user.fa.p/target_alpha_translate.c.o ninja: build stopped: subcommand failed. As well as a chunk of the various cross builds, see: https://gitlab.com/stsquad/qemu/-/pipelines/229443833/failures On the next re-spin could you include Kito Cheng's patch for linux-user support and also drop the version numbering from the commit titles so I don't have to file them off again. Thanks, -- Alex Bennée
