[PATCH] [MIPS] Remove unnecessary moves around DSP multiply-accumulate instructions

2020-02-06 Thread Mihailo Stojanovic
Unnecessary moves around dpadd and dpsub are caused by different pseudos being assigned to the input-output operands which correspond to the same register. Just like for the MSA multiply-accumulate instructions, this forces the same pseudo to the input-output operands, which removes unnecesary mov
