8134321: tools/pack200/Pack200Test.java crashes in the VM PIT jdk9 b79 Summary: Code that capture field values of eliminated allocation at a safepoint when there's an arraycopy behind a Phi is broken Reviewed-by: kvn

8075805: Crash while trying to release CompiledICHolder Summary: Removed nmethod transition to zombie outside of sweeper. Added cleaning of ICs of unloaded nmethods. Reviewed-by: kvn, iveresov

8133842: aarch64: C2 generates illegal instructions with int shifts >=32 Summary: Fix logical operatations combined with shifts >= 32 Reviewed-by: kvn, aph, adinn

8131969: jit/FloatingPoint/gen_math/Loops05 assert(2 <= size && size <= 16) failed: update low bits table Summary: assert in register allocation code when vector Phi for a loop is processed because code assumes all inputs already processed Reviewed-by: kvn

8133984: print_compressed_class_space() is only defined in 64-bit VM Summary: define method's empty body in 32-bit VM. Reviewed-by: coleenp

8078743: AARCH64: Extend use of stlr to cater for volatile object stores Summary: The current use of stlr on AArch64 to implement volatile stores needs to be extended to cater for object stores. Reviewed-by: kvn, aph, enevill

8133352: aarch64: generates constrained unpredictable instructions Summary: Fix generation of unpredictable STXR Rs, Rt, [Rn] with Rs == Rt Reviewed-by: kvn, aph, adinn

8133935: aarch64: fails to build from source Summary: add inlucde of oops/oop.inline.hpp to fix build Reviewed-by: coleenp

8133625: src/share/vm/opto/compile.hpp:96: error: integer constant is too large for ‘long’ type Summary: Wrap constant causing the failure into into CONST64(). Update comments. Reviewed-by: kvn

8076373: In 32-bit VM interpreter and compiled code process NaN values differently Summary: Change interpreter to use XMM registers on x86_32 if they are available. Add stubs for methods transforming from/to int/long float/double. Reviewed-by: kvn, mcberg

8133456: HeapRegionManager::shrink_by() iterates suboptimally across regions Reviewed-by: brutisso, tbenson

8067336: Allow that PLAB allocations at the end of regions are flexible Summary: PLAB allocations may return a buffer that is between minimum size (current allocation) and the desired size. This allows removes a large amount of fragmentation at the end of regions. Reviewed-by: tbenson, mgerdin

8130910: hsperfdata file is created in wrong directory and not cleaned up if /tmp/hsperfdata_<username> has wrong permissions Summary: Add check for fchir() failure and disable shared PerfMemory in that case. Reviewed-by: dcubed, simonis, gthornbr Contributed-by: christoph.langer@sap.com

8133951: Zero interpreter asserts in stubRoutines.cpp Summary: Allow zero sized code buffer when checking if there's enough remaining size Reviewed-by: kvn

8067339: PLAB reallocation might result in failure to allocate object in that recently allocated PLAB Summary: Properly size the PLAB to make sure that the object to allocate always has enough space in it. Reviewed-by: mgerdin, brutisso

8073146: G1 merges thread local age tables too early with global age table Summary: Move merging of age and survivor table to the end of GC. Reviewed-by: mgerdin, david

8040162: Avoid reallocating PLABs between GC phases in G1 Summary: Allocate G1ParScanThreadState at the start of GC and only deallocate at the end of GC. This automatically keeps the current PLAB intact without flushing it (and loosing lots of memory) for every reallocation. Reviewed-by: david, mgerdin

8133530: Add JFR event for evacuation statistics Summary: Introduce two new JFR events for young/old generation allocation statistics based on previous changes. Reviewed-by: ehelin, mgerdin

8073013: Add detailed information about PLAB memory usage Summary: Track and provide information about direct allocation, region end waste and failure waste for G1. Reviewed-by: jmasa, david, ehelin, mgerdin

8133470: Uses of Atomic methods in plab.hpp should be moved to .inline.hpp file Summary: Fix include file dependencies according to general guidelines for plab.hpp Reviewed-by: ehelin, mgerdin
