annotate src/os/solaris/dtrace/jvm_dtrace.h @ 5693:0356d95f01ba
While inlining, ensure proper anchoring of things that where anchored to the StartNode
Fix killCFG case where some dead nodes would not be removed, leading to later NullPointerExceptions
Fix Switch nodes simplification in case the node of the remaining successor changes because of deleting the other branches
Fix addDuplicates : do not patch inputs to the outer world if these inputs would point to an other graph
