However, if I remember correctly, on MIPS, function arguments are passed in registers, not on the stack. This could explain why gdb is not able to show the arguments in backtraces. The http://linux.junsun.net/porting-howto/porting-howto.html webpage also says: « Sometimes if you break on a function, you cannot see the correct value in variables and cannot do back-tracing. This is probably because certain registers are still not initialized [HELP: because kernel is compiled with -O2 flag?]. Step into the function a couple of lines, and you should see the variable and back-tracing fine. » Anyway, you'd better asking on the Linux-MIPS mailing-list rather than relying on my early-in-the-morning suppositions.
