IIRC this often appeared in matrix transpose code - movlhps / movhlps being replaced by unpcklpd / unpckhpd is the one I seem to remember. > > Overall - a massive improvement - thank you! > _______________________________________________ > LLVM Developers mailing list > LLVMdev at cs.uiuc.edu <mailto:LLVMdev at cs.uiuc.edu> http://llvm.cs.uiuc.edu <http://llvm.cs.uiuc.edu...
