The compiler options

Fields

singlepass: bool

Use Singlepass compiler.

cranelift: bool

Use Cranelift compiler.

llvm: bool

Use LLVM compiler.

experimental_artifact: bool

Use the experimental artifact format.

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).

enable_nan_canonicalization: bool

Enable NaN canonicalization during compilation to produce deterministic canonical quiet NaNs (QNaNs) across architectures.

disable_non_volatile_memops: bool

Disable LLVM non-volatile memory operations.

Available for LLVM.

enable_experimental_unaligned_memory_accesses: bool

Allow unaligned memory accesses.

This feature is experimental and currently supports only Cranelift scalar types and Singlepass on RISC-V for integral types.

features: WasmFeatures
