Is your "complete system data from multiple platforms" from JS apps?

Let's also not confuse "a sufficiently smart compiler..." with real-world observed performance :)

BTW data layout transformations like compressed fields would also be useful on 32-bit. The vast majority of object graphs would be happy with 16 or even 8-bit identifiers, not to mention JS numbers which are all 64-bit floats even on 32-bit platforms.

Let's also not confuse differences caused by 32 bit engines having more developers with differences caused by the platform.
