PUBLIC COMMENTS Fixed 6831323: Use v8plus as minimum required hardware for current Hotspot sources Problem: Current Hotspot sources use v8plus instructions so it can't be compiled with -xarch=v8. Solution: Use -xarch=v8plus as default for 32-bits VM. I also fixed the compiler version warning when building VM for jdk 1.6 with SS11 compilers.
