I'm going to look into the patch to check whether it could be implemented in peephole or some other common pass. > [drlvm][jit][opt][performance] Magic for java.math.Multiplication.unsignedMultAdd2 > ---------------------------------------------------------------------------------- > > Key: HARMONY-5826 > URL: https://issues.apache.org/jira/browse/HARMONY-5826 > Project: Harmony > Issue Type: Improvement > Components: DRLVM > Reporter: Aleksey Shipilev > Attachments: H5826-V2.patch, vm-jit-math-unsignedMultAdd2-magic-rc1.patch > > > Implementation of magic for java.math.Multiplication.unsignedMultAdd2, extracted in HARMONY-5825. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
