Some time ago I implemented a routine in gdb's command language that mimics the line number calculation performed by Python's virtual machine. Not thinking, I wrote it like so:
define lineno set $__co = f->f_code set $__lasti = f->f_lasti set $__sz = ((PyStringObject *)$__co->co_lnotab)->ob_size/2 set $__p = (unsigned char *)((PyStringObject *)$__co->co_lnotab)->ob_sval set $__li = $__co->co_firstlineno set $__ad = 0 while ($__sz-1 >= 0) set $__sz = $__sz - 1 set $__ad = $__ad + *$__p set $__p = $__p + 1 if ($__ad > $__lasti) break end set $__li = $__li + *$__p set $__p = $__p + 1 end printf "%d", $__li end This is more-or-less a direct translation of what Python's C code does. Unfortunately, the C code uses the break statement. Not being at the top of my game at the time I forgot that "break" means something entirely different in GDB's command language than in C. What's the equivalent? Set a flag and test? What about an equivalent for C's continue stmt?
