If a function was tagged with how many registers it required then those registers could be reused at its next invocation. Instead, in an attempt to optimize via inlining, that barrier is lost and register allocation and freeing is far messier to track. Indeed, that it compiles quickly with one invocation provides evidence that register use tracking is the issue... that and over inlining of functions.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
