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

Now automatically builds the toolchain by default. |

Added the divide unit to the list of ZipCPU dependencies. |

Fixed a compiler warning for an unused result. |

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. |

Adds internal link functionality to the specification document format. |

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. |

Minor formatting change. |

Minor changes. |

149 |
Updated the Makefile documentation and the all target. |

Minor changes to get LONG_MPY working, and adjust the documentation. |

Cleans up div_tb a bit, causing it to write SUCCESS out if successful and
abort if not. |

Fixes a problem where the assembler complained the compiler was trying to
move .org backwards. This is now fixed. |

This fixes the pipelined memory problem that was introduced a while back to
fix ... pipelined memory conflicts. This appears to maintain the success
of the fix, while recovering the pipeline memory performance that was had
before. |

Makes the auto-reload capability a configuration option, and fills out the
reset so that it is properly implemented. |

This section belatedly adjusts the zasm assembler so that it can handle
the LONG_MPY changes that have taken place. However, the test.S assembler
test script is still not properly testing the multiplies--at least it will
succeed on everything else. |

Bug fix--fixes some problems with conditional execution, as well as removing
an unnecessary peephole optimization. |

2905d 07h |

141 |
Fixes two bugs: one causing merged strings in the read only string section to
be referenced at the wrong address, and the second which caused the assembler
to fail at SYMBOL-OFFSET references. |

Minor changes, but fixes build of zippy_tb.cpp. |
dgisselq |
2907d 20h |

Changes necessary to document the changed instruction set: LDIHI became MPY,
and MPYU and MPYS became MPYUHI and MPYSHI respectively. See the specification
for more details. |
dgisselq |

This updates the CPU multiply instruction into a set of three instructions.
MPY is a 32x32-bit multiply instruction, returning the low 32-bit result,
MPYUHI returns the upper 32-bits assuming the result was unsigned and MPYSHI
returns the upper 32-bits assuming the result was signed. |

This should (again) fix the bug of trying to build optest.cpp. |

Oops --- missed a couple HOST_WIDE_INT values in a printf. This casts them
to (long), so that we can work on both PC's and ARMs. |
dgisselq |
2924d 11h |
/zipcpu/ |
135 |
Replaced all occurrences of INTVAL(...) on printf lines with (long)INTVAL(...).
This should fix the problems zip-gcc was having while running on the ARM. |

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

2925d 08h |

Changes preceding an instruction set update, which will change the multiply
operation from a 16x16 bit multiply to three types of 32x32-bit multiplies. |

Lots of minor bug fixes. |

Fixed a variable use before declaration error. |

Simplified the lock logic, and removed it when pipelining was not defined. This
also means the file is now dependent upon cpudefs.v. In another change, brev
was modified so as not to update the flags. This makes it useable with GCC
as a potential move or load immediate instruction. |
