I'm debugging a flaw in qemu-mipsel when I noticed that while gdb is finding the sources, it isn't claiming they are under /usr/src/debug. I looked for the debug file under /usr/lib/debug and all I see are these: -rw-r--r-- 1 root root 687536 Jan 12 12:43 /usr/lib/debug/usr/bin/qemu-ga.debug -rw-r--r-- 1 root root 261872 Nov 24 15:20 /usr/lib/debug/usr/bin/qemu-img-xen.debug -rw-r--r-- 1 root root 248984 Nov 24 15:20 /usr/lib/debug/usr/bin/qemu-nbd-xen.debug -rw-r--r-- 1 root root 1777104 Nov 24 15:20 /usr/lib/debug/usr/libexec/xen/bin/qemu-dm.debug Of course this made me wonder where I was getting my debug info from and it would seem that /usr/bin/qemu-mipsel (a.k.a. "/usr/bin/qemu-mipsel-static" on other distros) is not stripped and strings reveals it hasn't been debugedit-ed. (gdb) where #0 target_cpu_copy_regs (env=env@entry=0x62667b48, regs=regs@entry=0x7fffffffd830) at /tmp/portage/app-emulation/qemu-3.1.0-r1/work/qemu-3.1.0/linux-user/mips/cpu_loop.c:779 #1 0x000000006001625f in main (argc=<optimized out>, argv=0x7fffffffde98, envp=<optimized out>) at /tmp/portage/app-emulation/qemu-3.1.0-r1/work/qemu-3.1.0/linux-user/main.c:809 Is part of this intentional behaviour? i.e., is this debug info not copied and stripped because we know it will generally be copied into chroots? If this is the case, can we not run debugedit on it so that it will point to the proper sources? # emerge --info app-emulation/qemu Portage 2.3.51 (python 3.6.5-final-0,

The current behavior you are experiencing is a combination of RESTRICT=strip and the fact that we apparently currently ignore CFLAGS/LDFLAGS during build. I will push qemu-4.0.0 soon that should hopefully fix all of these issues.
