    Description

      Currently missing in divL_eReg, modL_eReg rules. These rules perform the calls to SharedRuntime, and as such should handle register saves properly.

      I believe we see a crash where XMM-spilled register is corrupted by divL call.

      The effect was introduced by JDK-7077312. arm.ad already has a similar effect on similar nodes.
