I add SSE support for FreeBSD 4.0-RELEASE and 5.0-CURRENT. Some more
work is needed everything to go well, but it works functionally now.
The patches and documents are avaiable at:
http://home.jp.freebsd.org/~issei/sse/sse.html
Limitations:
- Multiprocessor system is not supported.
- There is no exception handler to deal with SSE Exceptions.
- No spaces are available for SSE registers in struct fpregs. So, we
cannot record SSE registers when dumping core, nor access to SSE
registers via procfs.
Comments, bug reports etc. are welcome.
Issei.-
