version 0.3:
|
||||
|
||||
- initial support for ARM emulation
|
||||
- added fnsave, frstor, fnstenv, fldenv FPU instructions
|
||||
- added FPU register save in signal emulation
|
||||
- ARM port
|
||||
- Sparc and Alpha ports work on the regression test
|
||||
- generic ioctl number conversion
|
||||
- fixed ioctl type conversion
