Hi, I'm trying to implement fixnums ( http://blogs.oracle.com/jrose/entry/fixnums_in_the_vm ).
Task seems to be relatively easy. However, I don't know OpenJDK internals at all, so I'm asking for your help. First thing I'm trying to do is to override Integer.valueOf on 64-bit JVM. So, Integer.valueOf is already an intrinsic. I created class MakeIntFixnumNode extends Node, and I added code to library_call.cpp that converts Integer.valueOf call to MakeIntFixnumNode. And that's all. I stuck :) Have any suggestions? Am I moving in the right direction? Which parts of code should I patch? Another question: are there any documents, blogs, articles describing hotspot internals? -- Stepan _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
