Configuration data for the compiler

Fields

symbol_map: Option<HashMap<u32, String, RandomState>>

Symbol information generated from emscripten; used for more detailed debug messages

memory_bound_check_mode: MemoryBoundCheckMode

How to make the decision whether to emit bounds checks for memory accesses.

enforce_stack_check: bool

Whether to generate explicit native stack checks against stack_lower_bound in InternalCtx.

Usually it's adequate to use hardware memory protection mechanisms such as mprotect on Unix to prevent stack overflow. But for low-level environments, e.g. the kernel, faults are generally not expected and relying on hardware memory protection would add too much complexity.

track_state: bool

Whether to enable state tracking. Necessary for managed mode.

full_preemption: bool

Whether to enable full preemption checkpoint generation.

This inserts checkpoints at critical locations such as loop backedges and function calls, allowing preemptive unwinding/task switching.

When enabled there can be a small amount of runtime performance overhead.

nan_canonicalization: bool

Always choose a unique bit representation for NaN. Enabling this makes execution deterministic but increases runtime overhead.

enable_verification: bool

Turns on verification that is done by default when debug_assertions are enabled (for example in 'debug' builds). Disabling this flag will make compilation faster in debug mode at the cost of not detecting bugs in the compiler.

These verifications are disabled by default in 'release' builds.
