            Bug ID: 265322
           Summary: [JSC] Wasm GC struct members should be naturally
                    aligned
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jgriego at igalia.com

At present, e.g. ref members can be placed anywhere within the JSWebAssemblyStruct::m_payload allocation; for concurrent JIT on 32-bit (and, AIUI, concurrent GC on 64-bit,) these need to be 8-byte aligned.

Also, I suspect aligning the scalar types could be a slight performance win on ARM.
