Method and apparatus for optimising computer program code |
| 摘要 |
A method and apparatus for optimizing computer program code. The method comprises identifying at least one set of candidate instructions within the computer program code, each candidate instruction comprising an instruction for writing a constant value to memory and the at least one set comprising a plurality of candidate instructions. The method further comprises computing an aggregate constant value for the at least one set of candidate instructions, and replacing the at least one set of candidate instructions with at least one instruction for writing the aggregate constant value to memory. |

1. A method of optimising computer program code, the method comprising:
identifying at least one set of candidate instructions within the computer program code, each candidate instruction comprising an instruction for writing a constant value to memory and the at least one set comprising a plurality of candidate instructions; checking the validity of aggregating candidate instructions by checking whether the candidate instructions have volatile operands: computing an aggregate constant value for the at least one set of candidate instructions in response to the candidate instructions not having volatile operands; and replacing the at least one set of candidate instructions with at least one instruction for writing the aggregate constant value to memory. |
