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.

features: Features

triple: Option<String>

cpu_name: Option<String>

cpu_features: Option<String>

backend_specific_config: Option<BackendCompilerConfig>
