Expand description

Options that affect how optimization passes behave.

The Binaryen source code has more extensive documentation of these options than is reproduced here.

Fields§

§validate: bool

Validate both the unoptimized module and the optimized module.

Default: true.

§validate_globally: bool

Validate globally, not just locally.

Default: true.

§optimize_level: OptimizeLevel

The amount of optimization to apply.

The default depends on how OptimizationOptions is constructed.

§shrink_level: ShrinkLevel

The amount of effort to put into reducing module size.

The default depends on how OptimizationOptions is constructed.

§traps_never_happen: bool

Assume traps never happen at runtime.

Default: false.

§low_memory_unused: bool

Assume that the low 1K of memory is not valid for application use.

Default: false.

§fast_math: bool

Do faster floating point math by breaking official IEEE semantics.

Default: false.

§zero_filled_memory: bool

Assume imported memory is zeroed.

Default: false.

§debug_info: bool

Preserve debug info.

Default: false.

§arguments: HashMap<String, String>

Additional pass-specific arguments.
