Seems like it. I blew away and recreated the build tree, did a build with master, and then applied this pullreq with my usual process (so incremental build from there), and it was fine. Applied, thanks. Please update the changelog at https://wiki.qemu.org/ChangeLog/5.0 for any user-visible changes. -- PMM

I think your build dir is corrupted by a previous build. You should have old .o file without .d file, and thus the .o file is not refreshed (check the date of cpu_loop.o). We cannot cleanup that before starting the build. The purpose of the cleanup in configure was to avoid this kind of problem but I did it badly. If you want to check incremental build, cleanup your build dir, checkout v4.20 or master, build it, and then build the PR branch. it will work: it's tested. If you build 4.2.0, then master and then PR, the build dir will be corrupted by the build of master that removes the .d files without removing the .o files. So when you build the PR, cpu_loop.o file remains and is not rebuild with the new values in cpu.h. We can't do anything to avoid that now, except removing all .o files under *-linux-user... Sorry for the mess... Thanks, Laurent
