* Enable the already-passing `bulk-memoryoperations/imports.wast` test * Implement support for the `memory.init` instruction and passive data This adds support for passive data segments and the `memory.init` instruction from the bulk memory operations proposal. Passive data segments are stored on the Wasm module and then `memory.init` instructions copy their contents into memory. * Implement the `data.drop` instruction This allows wasm modules to deallocate passive data segments that it doesn't need anymore. We keep track of which segments have not been dropped on an `Instance` and when dropping them, remove the entry from the instance's hash map. The module always needs all of the segments for new instantiations. * Enable final bulk memory operations spec test This requires special casing an expected error message for an `assert_trap`, since the expected error message contains the index of an uninitialized table element, but our trap implementation doesn't save that diagnostic information and shepherd it out.
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.
