Adjusted the pdfinfo field, to accommodate Google's bot. |

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(). |

This fixes the problem whereby the ZipCPU didn't properly access more than
5 word-sized function parameters. |

Minor updates to the orconf.pdf pre-conference slide. (Added the 'to be
revealed' line. |

Added details of LM32 to the (pre) ORConf survey slide in trunk/doc. |

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. |

Updated the spec to reflect changes in the CC register: the user break
flag, and the ability to command a clearing of the instruction cache. |

Bugfix version. This fixes a problem whereby function addresses with offsets
were not properly calculated, together with properly setting up pcrelative
offsets when using the move function together with a label. |

Added a test to make certain that the arithmetic right shift was properly
propagating the high order bit. (The test works under verilator, but didn't
initially work in Xilinx -- thus a difference between the two.) |

Updated with inputs from Hellwig Geisse regarding the details of the ECO32
CPU. |

Trimmed OR1K instruction set down from 219 instructions, to the minimum number
of 48. Thanks to Olof for helping identify the minimal set! |

Noted 64-bit integers are by extension, as are vector instructions. |

Logic updates, and bug fix corrections to bring this in line with the current
XuLA2-LX25 SoC version. (i.e., the XuLA version was debugged and improved,
this update pushes those improvements to the mainline.) |

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. |

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. |

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. |
