| Author comments: | Deoptimisation can lead to a SIGBUS on 64-bit server VMs on SPARC and to an incorrect result on 32-bit server VMs on SPARC due to a regression introduced by the change: "6420645: Create a vm that uses compressed oops for up to 32gb heapsizes" (http://hg.openjdk.java.net/jdk7/jdk7/hotspot/rev/ba764ed4b6f2). Further investigation showed that change 6420645 is not really the root cause of this error but only reveals a problem with the float register encodings in sparc.ad which was hidden until now. |
