After get sw_64 pc, it is much slower than I guess (it is much slower
than my intel x86_64 laptop which was made in 2007-2008). So I have to
use tcg backend instead of tci.

Will qemu upstream accept alpha tcg backend to master tree? If possible
I can do it in my working time (after simply trying, I am sure, alpha
tcg backend can not work if only simply merge and let it pass building).

By the way, for me, I have to process alpha/sw_64 tcg backend firstly,
then process softmmu + linux-user.


Welcome any ideas, suggestions, and completions.

Thanks.
