I think those are all basic features that all major debuggers support, certainly gdb can do those including moving backwards (gdb calls it reverse debugging).

I think those are all basic features that all major debuggers support, certainly gdb can do those including moving backwards (gdb calls it reverse debugging). - Conditional breakpoints, break main.c:26 if a > 6 - Move instruction pointer, jump main.c:84 - Jump between threads, thread 123 - etc, etc. I've barely used Visual Studio, but I'm very familiar with windbg which uses the same debugger engine with a different UI.
