Not using the intrinsics for new llvm version is trivial, but we need to update our existing code (when intrinsics can't be used) to match what the auto-upgrader would do, otherwise we'll probably get really crappy code (at least I suspect in this case llvm won't recognize our patterns), which is of course the reason why we used intrinsics in the first place... (Can't really say I'm all that happy to see the intrinsics go, as the code to emulate it is rather complex with 8 instructions, thus blowing up IR size and likely compile time as well, but I guess that's life when compilers getting smarter...)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
