Description

opened on Sep 1, 2025

The host function definition region is not often used, and we hope it will be used less going forward as we move toward more use of IDL/deciding interfaces at compilation time. The use in hyperlight-wasm module mode can be replaced by a host function call, which does not require statically deciding on a dedicated memory region size.

    This was done in #453 and brought back in #600. Could be a useful reference

    Closing this issue since we did this in hyperlight core; see hyperlight-wasm#388 for the downstream issue.
