Did we ever figure out if it's possible to trick Hotspot into doing a JO instead of the raw bit-level operations? John/Christian/Tom: what would it take to get HS to "know" that we're doing an integer overflow-after-maths check and do the (faster?) JO? Rémi: For what it's worth, I did specialize +/- for 1 and 2 in the indy-based call protocols to avoid a full overflow check. - Charlie _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
