Lots of GCC bugs fixed, some new features added, longs should work now. The
build scripts have also been updated and simplified. |

192 |
Fixed a bug with constant alignment in the assembler. |

Updated toolchain, more information on the example debugger. |

Adjusted the opcodes to match the binutils port: added RTN instructions, and
allowed BREAK instructions to include an immediate--to be interpreted by the
debugger. |

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

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.) |

Fixed a compiler warning for an unused result. |

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

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. |

2948d 22h |
/zipcpu/trunk/sw |

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. |

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 |
2968d 02h |
/zipcpu/trunk/sw |
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. |

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. |

Lots of changes preparing the assembly for an instruction set change. While
implemented, they are still commented out via #ifdef LONG_MPY. By defining
LONG_MPY, this new change set will take place. |

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. |
