GDB/LLDB in order to find out all function's arguments in 'bt' output requires binary to be compiled without most optimizations. I use following debug-proven optimization level: -O2 for Release and -O0 for Debug builds. Xcode defaults to non debug friendly setting -Os.

I am trying to debug a hang in our kext. I have been using gdb and the kgmacro command showallstacks to get a dump of all the stacks in the kernel. Using the output from showallstacks and the gdb list command, I can map the return address in every frame in every stack to a location in the source code (as long as it's in our driver).

What I would like to do is get a listing of each threads stack which included the parameters for each call. I would like something similar to the backtrace command, but for all stacks. Is this possible in gdb? Is it possible to get a list of the parameters for all the calls on a particular stack?

Thanks,
