 // The result_register() for mips is the 'v0' register, which is defined
 // by the ABI to contain function return values. However, the first
 // parameter to a function is defined to be 'a0'. So there are many
 // places where we have to move a previous result in v0 to a0 for the
 // next call: mov(a0, v0). This is not needed on the other architectures.
