</span>Target-independent bitcode exists in the form of things like SPIR and PNaCl. These all have a DataLayout. The IR already implicitly depends on some of these things (e.g. pointer size), making it explicit doesn't break things.<br></blockquote><div><br></div><div>Correct.</div><div><br></div><div>+1 on Chandler's proposal from PNaCl's perspective.</div></div></div></div>
