Wasm bytecode optimization methods, execution methods, computer devices, and storage media

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform operations comprising:
• reading and parsing first Wasm bytecode, to obtain a Wasm module object;
• creating a linear memory and filling the linear memory based on the Wasm module object obtained through parsing;
• executing a start function in the Wasm module object;
• compressing execution result data of the start function to obtain a compressed execution result;
• modifying the linear memory based on the compressed execution result;
• replacing a corresponding data segment in the Wasm module object with data in a modified linear memory;
• encoding a Wasm module obtained by replacing the data segment to obtain an encoded Wasm module;
• and
• storing the encoded Wasm module as second Wasm bytecode.

One or more non-transitory computer storage media storing computer program instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:

• reading and parsing first Wasm bytecode, to obtain a Wasm module object;
• creating a linear memory and filling the linear memory based on the Wasm module object obtained through parsing;
• executing a start function in the Wasm module object;
• compressing execution result data of the start function to obtain a compressed execution result;
• modifying the linear memory based on the compressed execution result;
• replacing a corresponding data segment in the Wasm module object with data in a modified linear memory;
• encoding a Wasm module obtained by replacing the data segment to obtain an encoded Wasm module;
• and
• storing the encoded Wasm module as second Wasm bytecode.
