On most operating systems, the x16 and x17 registers are not special, so there is no benefit, and only a code size cost, to constraining AUT to only using them. Therefore, adjust the backend to only use the AUT pseudo (renamed AUTx16x17 for clarity) on Darwin platforms, or if traps are requested. All other platforms use the unconstrained variant of the instruction for selection. _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
