Changelog:
- added base/ folder
- base/base.hpp defines the version number for all UI targets, all the
varint-types, and a hook() class for debugger functions (see below)
- fixed compatibility profile compilation
- removed within<> template from the SNES target
- the SNES core can be built without Game Boy support now, if you so
choose (my SNES debugger is not going to support debugging the GBZ80,
sorry.)
- added ui-debugger; not at all useful right now, will be a long while
to get something usable ready
So hook is a class wrapper around nall::function. It allows you to
invoke potentially empty functions (and as such, the return type must
have a trivial constructor.)
It also doesn't actually perform the test+invocation when DEBUGGER
(options=debugger) is not defined. So you should have no overhead in
regular builds.
The core classes now have a subclass with all the debugging hooks, so
you'll see eg:
void CPU::op_step() {
debugger.op_exec(regs.pc);
(this->*opcode_table[op_read()])();
}
Clear what it's doing, clear what it's for. A whole lot less work than
inheriting the whole CPU core and virtualizing the functions we want to
hook.
All the logic for what to do inside these callbacks will be handled by
individual debuggers, so they can have all the functionality they want.
