            Bug ID: 239264
           Summary: [JSC] Minimize the prologue and epilogue of leaf
                    routines
           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: rmorisset at apple.com

I think that we currently always generate the same prologue and epilogue, regardless of whether or not that function calls anything or not.
We can probably omit some of that code for functions that call nothing, which I would expect would be a win at least for some Wasm code.
