1690965 - Extend wasm exception handling to full instruction set in proposal

Status: RESOLVED FIXED

(Core :: JavaScript: WebAssembly, enhancement, P3)

Description

[Asumu Takikawa]

The initial baseline compiler implementation of wasm exception handling in bug 1335652 was missing the following instructions from the current proposal: catch_all, unwind, rethrow, and delegate. This bug is for tracking improvements to extend the implementation to the full proposal.
