The interface can be rather minimal, if I recall correctly. But I guess nobody has looked into this since? The interface is indeed rather minimal, it basically only allows setting and removal of breakpoints and memory reading (and writing) (1). But GDB still expects an architecture it can

2012-06-13 Thread Bill Welliver
I noticed that folks have been working on code generation lately. Any chance it might be possible to implement some of the opcodes required to get debugging working (step, break, etc)? I seem to recall someone indicating it wasn't a terribly difficult task, but it's clearly beyond my

Actually, a much better solution would be to implement the JIT-debug info generation supported by gdb (including variable mapping etc). This should make it possible to simply debug using gdb, with symbols. This can be done using a plugin with GDB 7.5+ (I think)

That would probably help with viewing of stacktraces and variable data, but wouldn't opcodes still be needed to actually control stepping and breakpoints in the app itself? I guess it's possibly worth mentioning that I have a long-standing bounty available for tasks that lead to viable
