7005241: C1: SEGV in java.util.concurrent.LinkedTransferQueue.xfer() with compressed oops Summary: Implementation of the CAS primitive for x64 compressed oops was incorrect. It kills rscratch2 register (r11), which is allocatable in C1. Also, we don't need to restore cmpval as it's never used after that, so we need only one temporary register, which can be scratch1.

6961690: load oops from constant table on SPARC Summary: oops should be loaded from the constant table of an nmethod instead of materializing them with a long code sequence. Reviewed-by: never, kvn

7003554: (tiered) assert(is_null_object() || handle() != NULL) failed: cannot embed null pointer Summary: C1 with profiling doesn't check whether the MDO has been really allocated, which can silently fail if the perm gen is full. The solution is to check if the allocation failed and bailout out of inlining or compilation. Reviewed-by: kvn, never
