7012642: G1: JumbleGC002 test aborts with segmentation violation due to uncaught stack overflow Summary: With recent G1 allocation path changes, the value of StackShadowPages in fast debug builds of the JVM, is no longer large enough to prevent the JVM C++ code from touching the stack guard pages. Increase the value of StackShadowPages to a suitable value. Reviewed-by: ysr, tonyp, coleenp

tonyp [Wed, 19 Jan 2011 09:35:17 -0500] rev 7920
7011379: G1: overly long concurrent marking cycles Summary: This changeset introduces filtering of SATB buffers at the point when they are about to be enqueued. If this filtering clears enough entries on each buffer, the buffer can then be re-used and not enqueued. This cuts down the number of SATB buffers that need to be processed by the concurrent marking threads. Reviewed-by: johnc, ysr
