wasm-opt: Apply all optimizations and write to a given file (takes more time, but generates optimal code).

wasm-opt

$ wasm-opt -O4 ${input-wasm} -o ${output-wasm}

try on your machine

This command is using the wasm-opt tool to optimize a WebAssembly (Wasm) binary file. Here's a breakdown of each component:

wasm-opt: This is the command for running the wasm-opt tool. It is used to optimize and transform WebAssembly modules.
-O4: This flag specifies the level of optimization to be performed. In this case, -O4 indicates the highest level of optimization.
${input-wasm}: This is a placeholder for the input Wasm binary file. The command assumes that you would replace ${input-wasm} with the actual path or name of your input Wasm file.
-o: This option specifies the output file name.
${output-wasm}: This is a placeholder for the output Wasm binary file. Like the input Wasm file, you would replace ${output-wasm} with the desired name or path for the optimized output file.

In summary, the command takes an input WebAssembly binary file, applies the highest level of optimization with the -O4 flag, and generates an optimized Wasm binary file with the specified output name or path.
