Updated binutils. This fixes problems with linking global variables, fixes
the map file report, adjusts the LJMP instruction disassembly to display the
resulting address, as well as in general fixing up link problems when
sizeof(byte) is 32-bits. |

A bug fix, applies to when there are more than 9 interrupt lines into the CPU. |

Fixes a bug that killed make binutils before the build-gas directory
was created. |

Bug fix: the Makefile wasn't building gcc, and the binutils would not allocate
space for common variables or zero'd (bss) variables properly. Several binutils
bugs were fixed to get variables to be allocated properly. Those are
reflected in this updated patch. |

Bug fix compiler update! This fixes a lot of the bugs associated with the
previous compiler release. |

The makefile no longer requires (or supports) building the obsolete machine
code test file optest. |

This file is now marked as obsolete. |

Just to clarify expectations ... this makefile hardly builds anything. |

Adding a missing file. |

Updated to allow building without the sources for the graphics used in the
document. |

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. |

A barely functional, but somewhat working, version of GCC to check in.
If the Lord is willing, it should be accompanied by a newlib port soon.
That port should move the GCC status from barely functional but somewhat
working to functional and working, although not (yet) complete. |

Updated bugfix version of the binutils patch, and a first patch of GCC.
The GCC patch is undergoing ongoing and active development. It is also known to
continue to contain active bugs. (It's not done yet.) |

Adjusted the "BREAK" instruction so that it will now disassemble properly
with an operand. This was necessary to create a (trap_if ...) instruction
for the GCC compiler. |

Some changes to support early branching: branches are now ADD #x,PC instructions
instead of MOV #x(PC),PC--providing greater range to the CPU. When that range
is insufficient, ZPARSER now recognizes long jump instructions coded as
LOD (PC),PC followed by the jump address. (This change was made necessary by
the need to build an assembler/linker that could create instructions that would
jump to any address in the 32-bit address space. In short, a part of the
ongoing GCC upgrade and rework.) |

Added big-endian versus little-endian functionality. You can now specify which
your input file is as a command line parameter, and zdump will properly
disassemble the file. |

Added justed longjump instructions from the previous (not used, broken)
functionality to the new LOD (PC),PC functionality. |
