...fied the object layout (in MMTkObject.h?), it probably means that you use a different object layout? What kind of modifications have you introduced? Because if you have changed the object layout of Java objects, it can potentially impact all the code of J3 and VMKit...

Hi, I am wondering how I can get the JIT'd llvm IR during VMKit execution. I am stuck in precompiling phase (when loading library classes), and I am facing various problems. If I can log the JIT'd llvm IR (from Java bytecode), that would be convenient. I turned on --enable-debug, but it doesn't seem very helpful at this stage. Any other suggestion is welcome. Thanks very much.

Hi, I replaced the MMTk code with a C-version MMTk code (I have been working on such AOT compiler for a while). The compiler should deal with most of the MMTk code base correctly - at least I get marksweep running with a tiny client). So I am trying to put the C version MMTk back with VmKit. I tried not to change much existing code except where necessary, such as name mangling and MMTkObject

Hi, I am interested to know how to get the most optimised IR (the compiler won't do any higher level opt but only translates it down to MC). I tried to emit LLVM IR in clang by using '-S -O3 -emit-llvm'. Then I tried to use 'opt' to optimise it, but it seems to produce the same code. Can I assume that LLVM will not do any code transformation on this level of IR but
