...ement. But how does the optimizer "know" this without being Java specific? It seems like LLVM will have to have some built-in notion of a "null pointer" generated exception. Similarly for divide by zero, e.g.: void bar(int x) { if (x != 0) this.y = 100/x; // no ArithmeticException possible here } How will the optimizer "know" the exception can't happen? ------ Another random question: can a global variable be considered variable in one function but constant in another? Motivation: Java's "first active use" requirement for class initializ...

This is the direction that we plan to go, when someone is interested enough to implement it. There are some rough high-level notes about this idea here:

...eld1 and x.field2 will involve getelementptr instructions, we can have some logic in an optimization pass to prove what you are saying: if x is null then only the first memop through a getelementptr on x will trap. > void bar(int x) { > if (x != 0) > this.y = 100/x; // no ArithmeticException possible here > } > > How will the optimizer "know" the exception can't happen? This should be pretty straight forward to implement as well (by writing the proper optimization pass). > ------ > > Another random question: can a global variable be considered va...

I also misunderstood :) So, in this case, the problem is that your version of openjdk is probably not supported. In fact, we only support the version 7u23 of openjdk :) You can find this version here: http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html#jdk-7u25-oth-JPR Currently, I'm modifying the internal design of vmkit and I'm not working

I guess I mispoke, I checked out the source from http://llvm.org/svn/llvm-project/vmkit/trunk. I thought this was vmkit2. I guess I was just referring to vmkit then.
