The compiler options

Fields

singlepass: bool

Use Singlepass compiler.

cranelift: bool

Use Cranelift compiler.

llvm: bool

Use LLVM compiler.

enable_verifier: bool

Enable compiler internal verification.

Available for cranelift, LLVM and singlepass.

compiler_debug_dir: Option<PathBuf>

Debug directory, where IR and object files will be written to.

Available for cranelift, LLVM and singlepass.

profiler: Option<Profiler>

Enable a profiler.

Available for cranelift, LLVM and singlepass.

_enable_pass_params_opt: bool

Deprecated option as m0 optimization always play role if we use a static memory

compiler_threads: Option<NonZero<usize>>

Sets the number of threads used to compile the input module(s).

features: WasmFeatures
