Hi all,
Please review this patch to add support for large bitmaps in the SA.
http://cr.openjdk.java.net/~stefank/8218743/webrev.01/
https://bugs.openjdk.java.net/browse/JDK-8218743
I've added a minimal interface (at, atPut, clear) that uses longs
instead of ints, and changed MarkBits to use this interface.
I've implemented a segmented bitmap that, currently, all GCs use when
asked for a bitmap in MarkBits. Later ZGC will provide its own
discontiguous bitmap, implementing the new interface, but that will be
sent out as a separate RFE.
I've tested this with a temporary patch that lowers the segment size
and implements a jtreg test:
http://cr.openjdk.java.net/~stefank/8218743/webrev.test.01
I ran through the all the tests in serviceability/sa with both these
patches.
Thanks,
StefanK
