Currently, the asm output file for MIPS has no rev info.
It can make some trouble, for example:
assembler is mips1 by default,
gcc is fpxx by default.
To assemble the output of gcc -S, we have to pass -mips2
to assembler.
The same situation is for some CPU has extension insn.
Octeon is an example.
So we can just add ".set arch=octeon".
If an ASE is enabled, .module ase will also be used.
