Revision: 1.3
Committed: 2003-09-07T14:33:54Z (21 years, 2 months ago) by gbeauche
Content type: text/plain
Branch: MAIN
Changes since 1.2: +31 -1 lines
Log Message: 
- Integrate new NativeOp instructions to be used as trampolines to call
  native functions from ppc code.
- Little endian fixes in emul_op.cpp
- Add new 'gpch' 750 patch to workaround crash with MacOS 8.6
- Don't crash in Process Manager on reset/shutdown with MacOS 8.6
- We also have an experimental interrupt thread in emulation mode
