My compiler (which is not gcc) happens to generate stabs. So I have to do it 
with stabs. Currently the compiler misuses a N_ROSYM to pass frame info to 
its debugger. However, gdb does not like this.

Are there other targets where a stab is used for frame information?

The instruction format of the debug target is so complex that decoding the 
prologue is not a real option.

Cheers,
Jan
