Oh, thanks. Since then, I guess we should generate these .S files
when build instead of put them in the source code.

I will have a look at it.

In fact we treat MIPS r6 as total different architectures.
In future, we may replace the current r2 with r6, while never `update'.

Currently, we just make the source compatible.
