> It all looks reasonable, but I'm still not clear on the connection between CCallingConventionRequiresIntsAsLongs and signx in move32_64.  Do they cover different paths, so both are needed, or does CCallingConventionRequiresIntsAsLongs mean that move32_64 is used less often?

It’s my understanding that they do cover different paths. The mov32_64 change is used for native java method calls and CCallingConventionRequiresIntsAsLongs covers calls to the runtime from a compiled java method.
