Robin,
I did a diff of the mmtk/vm directory. It looks like nothing really
changed
in the vm interface code which is good. Am I understanding this right??
That sounds about right. And (famous last words) I think the interface
will probably remain stable for a while now.
I did notice a change in utility/scan/mmtype.java.
getSlot(ObjectReference,
int) returns addr.plus(VM.ARRAY_BASE_OFFSET).... instead of
...plus(arrayOffset)...
I actually stumbled on this bug during bringup. I replaced
...plus(arrayOffset)... with ...plus(12)... Its a hack. But now it looks
like I simply set ARRAY_BASE_OFFSET to 12 during <clinit>. Does this seem
right??
That's the intent, yes. Each VM provides its array base offset as a
constant.
cheers
