This allows us to detect when stack walking has failed to walk the whole stack, and we are potentially missing on-stack roots, and therefore it would be unsafe to do a GC because we could free objects too early, leading to use-after-free. When we detect this scenario, we skip the GC.
This is the wasmtime-runtime crate, which contains wasm runtime library
support, supporting the wasm ABI used by wasmtime-environ,
wasmtime-jit, and wasmtime-obj.
This crate does not make a host vs. target distinction; it is meant to be compiled for the target.
Most users will want to use the main wasmtime crate instead of using this
crate directly.
