Shark just JITted its first bytecode:

load i32* %local0               ; :15 [#uses=1]
inttoptr i32 %sp to i32*        ; :16 [#uses=1]
store i32 %15, i32* %16
%sp1 = sub i32 %sp, 4           ;  [#uses=2]

Ladies and gentlemen, it is aload_0!

Yesterday I had a mini-milestone in that I got enough bits and pieces written to have HotSpot call my JIT’s compile_method() method. The next trick will be to get a piece of code back into HotSpot without it being relocated on the way.

Of course, the zero interpreter doesn’t have profiling, so it only works if you force it with -Xcomp at the moment.

Also, I disabled InlineIntrinsics, which reminded me that there was some kind of fast accessor thing for JNI that I disabled in the original ppc port. I should fix that at some point.
