when BYTES_IN_COPY == 8 then aligned32Copy in org.jikesrvm.runtime.Memory can incorrectly copy 8 bytes (4bytes + 4 bytes) when src is 4 byte aligned. The attached patch adds a series of assertions that verify the assumptions described in the Javadoc and an explicit check for if numBytes == 0
ia32 with SSE2 enabled
As noted by Daniel there is a commented out call to aligned32Copy at line 319 in Memory.java, uncommenting this call and removing the rest of this method passes the pre-commit tests but more validation (and probably an entire regression run) is needed.
Commited fix in r16017.
bulk close of all resolved issues in preparation for 3.1.3 release.
