Performance is an issue, but the overhead of storing the > arguments on the stack is likely worth the added debug info. In this case you would probably have to modify the compiler to save all arguments. Another issue is actually finding the stackframe. For a debugger using debug information this is possible but short of that it's hard on MIPS to produce a meaningful backtrace. Or having something as complicate as on ia64 ... Ralf
