(Previous failures came from my messy codebase.) The current problem is some benchmarks are improved but some are degraded. The total scores are almost equal for with/without global propagation. The two most degraded benchmarks are crypto.aes and scimark.lu.small - degraded about 10%. I'm going to check whether the reason is increased compile time or not. > [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, H5826-V3.patch, H5826-V4.patch, H5826-V5.patch.zip, H5826-V6.zip, 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.
