Added FP math support to support library
Uses code lifted from old version of GNU libc, no adaptation needed
NEEDS testing! |

Modified 'hello' to use new support code
NOTE: the 'OPCODE EMULATOR' mentioned below is the TRAP HANDLER
The SW opcode emulation has been working for months |

Updated simulation script for 'hello' sample: now uses function call log.
It is useless in this demo, but it shows how to use it. |

Modified simulator, added some debug functionality:
- Optional emulation of some MIPS32r2 opcodes
- Function call trace log using map file (crude implementation)
Plus a few small bug fixes |

Added (very early draft, very incomplete) reserved opcode trap handler.
Updated opcode tester to test some emulated mips32 opcodes using the trap handler. |
