   > Are there any ARM64/aarch64-specific patches that should be applied but   
   aren't in the current patch set?   
      
   No, all patches are unconditional.   
      
   > Is there a known issue with js_GetClassPrototype() on ARM64 with this   
   version of SpiderMonkey?   
      
   No, we haven't seen issues on other systems, and have been using this for   
   quite a while.   
      
   > The build uses `--with-system-nspr` — could there be an incompatibility   
   between system NSPR (from Debian) and the SpiderMonkey build on ARM64?   
      
   I would be very shocked, NSPR4 has been an exceptionally stable API for a very   
   long time. They do it right, and I trust them a lot.   
      
   > Could there be an issue with the libffi ARM64 calling conventions?   
      
   The build should be completely replacing the included libffi with the one in   
   `3rdp/dist` (v3.5.2) before the build. If looking at newer releases of libffi   
   suggests something has changed, you should be able to test by simply swapping   
   libffi.tgz out there.   
      
   I'll dig into this info, thanks for following up!
