implementing step over, dwarf

Question

Hi,

Im working on a source level debugger. The debug info available in elf format. How could be 'step over' implemented? The problem is at 'Point1', anyway I can wait for the next source line (reading it from the .debug_line table).

Thanks

if (a == 1)
 x = 1; //Point1
else if (a == 2)
 x = 1;

z = 1;
