Added a test to see if the compiler properly handles a large number of
arguments. Further, the sibcall enabled compiler now correcly makes a
sibcall from the end of txreg(). |

An updated version of the intensive CPU test. This one runs from C, and
requires a UART port and a PIC, but can run quite successfully on multiple
SoCs that have been built with the ZipCPU internal to them. |

Now supports building a simulator that can load ELF files, such as GCC and/or
binutils will produce. |

Improved debug trace quality, for finding bugs after the fact. |

Added timing checks on the busy and valid signals: either one of the two is
valid, or the whole is idle. |

Updated to match the new/updated multiply instructions. Of course, this is
still hand optimized and not compiled--so it's not really a true and proper
test (yet), but ... it's what I have. |

abort if not. |

Working updates, to keep this up to date with the RTL code. |

Fixed some nasty early branching bugs. Adjusted the Makefile to declare that
cpudefs.h was automatically generated from cpudefs.v, and made sure that
zipbones included the cpudefs.v so it could get the DEBUG_SCOPE define.
In addition, the test.S was updated to test long jumps, the early branching
bug we found, and all three early branching instructions: ADD #x,PC, LOC(PC),PC,
and LDI #x,PC. |

Adjusted the operator input line to reflect actual logic inputs, rather
than the registered inputs which may have been out of date. (Indeed, they
were out of date for the bug I was chasing and fixed ...) |

Removed the requirement to have the dev.scope.cpu hardware defined outside
of the Zip CPU (it was defined in another project). This was causing a bus
error in the simulator (which it should have), but taking it out fixes things
in the simulator (while removing capability from one special piece of H/W). |

The biggest change here was to zippy_tb, to make it more similar to the debugger
and to make it work with VLIW-type instructions. |

well as two new testing assembly files. |

This implements the "new Instruction Set" architecture for the Zip CPU. It's
a massive change set, that touches just about everything but probably not
enough of everything. Please see the spec.pdf for a description of this
new architecture. |

Some bug fixes to the dhrystone benchmark, and some compile time defines for
the test bench processor. Of the most important note is the fix to detect
lockups on the debug/wishbone bus--that has been a real help in getting the
ZipCPU installed and the debugger working on the various boards I'm working
with. (i.e., it's helped me find and figure out why/when things haven't worked)
Of other note is the new 'G' key in the testbench code, to cause the test
bench to run without user interaction until the next keystroke. This is
very valuable in long programs, as it makes getting to/from breakpoints
easier (i.e. you don't have to wait as long, hit 'G', breathe, hit 'space'
and you're there). |

the bus from the CPU, as well as the test file that proved they worked. |

*Lots* of changes to increase processing speed and remove pipeline stalls.
Removed the useless flash cache, replacing it with a proper DMA controller.
"make test" in the main directory now runs a test program in Verilator and
reports on the results. |
