With this patch</div><div>I've alleviated my concerns with forcing cross module behavior for all users of JIT. However this introduces some </div><div>new semantics, and kind of circumvents the EngineBuilder API. More important though, I have not addressed</div><div>any concern about using stub functions in eager compilation mode. I don't yet understand this concern since</div><div>these stubs are compile time only, and it seems that the pending function system inherently uses stubs. Anyway</div><div>I'm sure my understanding will get fixed soon enough. :-) The new code is NOT commented.</div><div><br></div><div>This patch was NOT attached to <span class="Apple-style-span" style="font-family: sans-serif; -webkit-border-horizontal-spacing: 1px; -webkit-border-vertical-spacing: 1px; "><a href="http://llvm.org/bugs/show_bug.cgi?id=2606" style="color: rgb(102, 51, 102); ">2606</a>.
