about dalvik's gc

[marianne]

Hi, All:
After reading almost all the source code about dalvik GC recently, I
am concerned that, though the GC uses the mark-sweep algorithm,
there is an object header defined in struct DvmHeapChunk which
contains the information of object generation , cited as follows:

typedef struct DvmHeapChunk {
#if WITH_OBJECT_HEADERS
......
u2 birthGeneration;
u2 markCount;
u2 scanCount;
u2 oldMarkGeneration;
u2 markGeneration;
u2 oldScanGeneration;
u2 scanGeneration;
.....

I also noticed that, the "birthGeneration" is actually
useless in this mark-sweep algorithm.
Does this imply that you are planning to improve the
current GC to a generational mark-sweep garbage collector?:-)
I hope my question is not reckless :P
Thank you for your help.

Yes, the Dalvik GC is heavily being worked on as we speak. Of course, I can't give any ETA about availability of the next version.
