[Crash-utility] given a makedumpfile processed coredump, generate a symbolic backtrace containing the same info as a standard gdb backtrace

Hi all, I've got a coredump file processed by makedumpfile (non-elf) and am trying to get a backtrace with all the line numbers, argument values, and argument types like a normal gdb backtrace with debug info (yes, I have a vmlinux built with debuginfo). gdb refuses to load the core dump (no big supprise there). crash loads it but it's builtin backtrace doesn't appear to use debug info, and as a result doesn't give me arguments + types. Doing "gdb bt" complains about not having a stack. Any advise? I see a few paths forward: - somehow get crash's gdb to understand where the stack is - hack gdb to load the non-elf coredump - modify makedumpfile to allow it to convert the non-elf coredump back to elf. Thanks.
