With the changes in this repository, BigInts have support for bidirectionally converting to 64-bit integer WebAssembly values, which appears as
- Parameters and return values to exported WebAssembly functions
- Parameters and return values to host functions
- Imported and exported globals
BigInts can be read or written from WebAssembly memory using the BigInt proposal's BigInt64Array or BigUint64Array; no additional support is needed.
