Updated toolchain, more information on the example debugger. |

/zipcpu/trunk/sw/gcc-zippatch.patch |

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

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

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

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. |

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. |

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. |

Lots of changes and bugfixes. The disassembler produces more readable output.
The assembler and linker will no longer automatically use LDIHI--in preparation
for switching to LONG_MPY. LDIHI/LDILO pairs have been changed to BREV/LDILO
pairs. Within the compiler, conditional moves have been rebuilt. They're not
perfect yet, but they are better. Lots of peephole optimizations, etc. |

This patch contains minor updates. Two are important to mention: 1) It turns
the compare optimizations back on within the zip.md file, and 2) it fixes an
internal compiler fault that was causing the compiler to such up all of my
memory in an infinite recursion. |

Lots of changes, lots of bugfixes--both to the compiler as well as to the
assembler. (Ex: the assembler will now properly execute a LDI _sym+5,R0).
Many compiler optimizations have been turned off, however. They will probably
be turned back on in the near future--once I get this version proven without
them. |

This represents a major rewrite of the machine definition file, gcc/config/zip/
zip.md. In particular, the architecture has been changed from a "cc0"
architecture to one with a specific CC_REG and CCmode. Instructions in the
machine definition file must now explicitly set this register with their
results. The result is better condition code handling, better usage of the
conditional execution modes of certain instructions, and even some decent
optimizations. |

Bug fixes: This adds the zip_ucc() instruction as a builtin, fixes the zip_cc()
builtin (both are now unspec_volatile) together with fixing the *_context(int*)
builtins so that they use five registers, never four. Further, this fixes the
negative stack space offset bug. Many of the GCC files now have Zip debugging
hooks within them as well, to simplify further debugging of the compiler. |

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

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.) |
