Re: [cc65] Debugging with VICE

Ok I'm not getting emails back from the list when I post, so hopefully
this comes through.  I'm trying to follow the rules.  =]

Well certainly the UI of NESICIDE could be adapted to be an IDE for
any emulated platform, and will run on any host platform that Qt
builds for [Linux, OSX, Windows, ...].  As I mentioned in a prior
reply the emulator is a .dll/.so with a fairly clean-cut API so really
all that would need to be done would be to replace the NES-emulation
core with a C=64-emulation core and adapt the necessary APIs to the
new core.

I've written a wrapper-layer around the CC65 dbginfo APIs for NESICIDE
that kind of helps 'wade through' the dbginfo data to retrieve what is
necessary to support things like being able to figure out machine
addresses from source file name and line number [for supporting
setting breakpoints] and to do the reverse [for tracing execution
while stepping].  At the moment that wrapper-layer uses Qt internals
such as QString and QStringList so it wouldn't be directly exportable
as a DLL to be used by Vice to get what it needs to get--but it
probably wouldn't take too long to rework it to use standard library
stuff instead of Qt stuff.

I just downloaded the snapshot and the dbinfo.c/.h are no different
than the one I'd been using since February.  I took a look and, no, I
have not yet added support for types [that'll come in handy for the
symbol watch window].  I haven't even added support yet for csym's.  I
should do that!
