  • Method for improving execution performance of multiply-add instruction during compiling
    Patent number: 9081561
    Abstract: The present invention relates to a method for improving execution performance of multiply-add instructions during compiling, comprising the following steps of: compiling a source code by a compiler to acquire internal representation; optimizing; generating a machine code on the basis of a target processor, and allocating a physical register to a pseudo-register in the machine code; and improving results of register allocation to multiply-accumulate instructions. The method for improving execution performance of multiply-add instructions during compiling provided by the present invention has the following advantages: the compiler is allowed to realize procedure optimization by acquiring the optimal MAC (multiply-accumulate) instruction use gain.
