Stephen Anthony e61caf069b Fix warnings under gcc and clang, both in normal compilation and R77 mode. 2019-03-09 19:40:45 -03:30
Stephen Anthony abc3b3a32b Fix warnings generated by clang 8. 
- Several more still exist, and are mostly related to C-style code
- It has long been my intent to remove as much C-style code as possible

Darrell Spice, Jr 490724c079 Updated BUS to new spec 
The Harmony/Melody BUS driver is undergoing a major revision to add support for the new JMP FASTJUMP feature.  This update implements the changes, as well as the fast jump feature which isn't yet in the HMdriver.  It also implements the load/save state support as well as the BUS debugger widget.

A few minor updates to CDF were also done.

Note that this update breaks compatibility with the previous BUS demos.
 2017-05-07 14:43:54 -05:00
Stephen Anthony fd4122e017 Re-abled state loading/saving. 
There's still a few final items to fix, but it's 99% complete.
 2017-03-25 17:58:58 -02:30
Stephen Anthony 95c7b30a45 Some updates to the last BUS/CDF commit: 
- update some code to the '5.0' way of doing things
  - allow compilation in Linux
  - whitespace/tab fixes to match main codebase
  - add some extra comments
  - test compile under gcc 6 and clang 5, and fix some warnings
 2017-03-24 18:02:08 -02:30
Darrell Spice, Jr 6227186feb Preliminary support for BUS and CDF 
Preliminary support for new Harmony/Melody drivers BUS and CDF.  Work remains for the 3-Voice Audio, Digital Sample playback, and some additional revisions to the debugger widgets.

Unknown 97a229dd92 ARM Timer 1 support 
Implemented ARM Timer 1 support in Thumbulator.  Revised DPC+ to use it.

Stephen Anthony abb7097cb7 Removed $Id$ stuff from codebase, since it's Subversion-specific. 
Whitespace cleanup and update copyright to 2017.

stephena 40cfd6a475 Cleaned up usage of 'using namespace ...'. I'm currently teaching that using 
that approach is a bad idea (and using Stella as example code), so it doesn't
make sense to not do something as it's being taught; the correct way.

stephena aa5691af8a OK, it looks like I'm back to Stella development, after a several month 
break.  First thing to do is update the year.  Happy new year to anyone
reading these commit logs.

stephena 95fe213f3a Consolidated the code for converting integers to strings in various 
bases into a Common::Base class.  Previously, this functionality was
spread across several classes, and used different approaches to formatting.
While the code still mixes C++ streams and C-style sprintf's, at least
it will now be easier to modify it all in one place.

Related to the above, added ability to use upper or lower case
characters for HEX output in the debugger.  This is toggled by the
new debugger prompt command 'uhex', which is also tied to a new
commandline argument, 'dbg.uhex'.

stephena f003bd31bd Changed disassemble and debug checks from run-time to compile-time 
for Thumb ARM emulation.  On my (quite fast) system, this results in 4%
less CPU usage, so it should be much better on slower systems.

stephena 2145c38087 Fixed bugs in DPC+ scheme; reset wasn't actually resetting the 
Harmony RAM, and state saving wasn't working at all.
