|
- Apply default optimizations and write to a given file:
|
|
|
|
|
|
|
|
|
|
`wasm-opt -O {{input.wasm}} -o {{output.wasm}}`
|
|
|
|
|
|
|
|
|
|
- Apply all optimizations and write to a given file (takes more time, but generates optimal code):
|
|
|
|
|
|
|
|
|
|
`wasm-opt -O4 {{input.wasm}} -o {{output.wasm}}`
|
|
|
|
|
|
|
|
|
|
- Optimize a file for size:
|
|
|
|
|
|
|
|
|
|
`wasm-opt -Oz {{input.wasm}} -o {{output.wasm}}`
|
|
|
|
|
|
|
|
|
|
- Print the textual representation of the binary to console:
|
|
|
|
|
|
|
|
|
|
`wasm-opt {{input.wasm}} --print`
|
