  "message": "Better debugging support\n\nNow builds 64b with debugging support, and on x86, it retains the original 64b\nobject.  Once we objcopy, we lose the ability to use some debugging tools, such\nas addr2line.\n\nThis retains the 64bit original version of the kernel, which will be large if\nyou use a big KFS.  But no one should be doing that anymore.  If you do, you\ncan comment out the cp in k/a/x/Makefile (but don\u0027t commit it).\n\nWith this change, you can do things such as:\n\n$ x86_64-ros-addr2line -e obj/kern/akaros-kernel-64b\nffffffffc0321cef\n/usr/local/google/home/brho/akaros/ros-kernel/kern/src/process.c:551\n^C\n\n$ gdb obj/kern/akaros-kernel-64b\nReading symbols\nfrom akaros-kernel-64b...done.\n(gdb) list *0xffffffffc200d030\n0xffffffffc200d030 is in abort_all_sysc (kern/src/kthread.c:739).\n734/* This will abort any abortabls at the time the call was started.
