Abstract
Systems and methods for binary translation of executable code. An example binary translation method comprises: decoding a current source code fragment compatible with a source instruction set architecture (ISA); identifying a first source register referenced by the current source code fragment; determining that the first source register is not referenced by a register mapping table, wherein the register mapping table comprises a plurality of entries, each entry specifying a source register, a target register, and a weight value; identifying, among the plurality of mapping table entries, a mapping table entry comprising a highest weight value, wherein the identified mapping table entry specifies a second source register and a second target register; replacing, in the identified mapping table entry, an identifier of the second source register with an identifier of the first source register; and translating, using the mapping table entry, the current source code fragment into a target code fragment, wherein the target code fragment is compatible with a target ISA.
