Removed the (now unused) old GCC compiler, v5.3.0 |

Additional ZipCPU changes associated w 8b upgrade |

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

/zipcpu/trunk/sw/ |
192 |
Fixed a bug with constant alignment in the assembler. |

191 |
Updated toolchain, more information on the example debugger. |

188 |
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. |
dgisselq |
3030d 01h |
/zipcpu/trunk/sw/ |
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. |

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 |
3049d 04h |
/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. |
