Hi Chris,

n2 := self unsignedLongAt: index+4 bigEndian: true.

These are obviously bigEndian now, nto litte-endian.

Does this mean Smalltalk order (or now Squeak order) has changed?

This is not for general purpose.  The method is part of VMMaker.  Let's take it to vm-dev. 
It's a simple mistake.  If you look at long64At:put: you'll see the comment is correct:

long64At: index put: val
"I store 64-bit integers in Smalltalk (little-endian) order."
self unsignedLongAt: index put: (val bitAnd: 16rFFFFFFFF) bigEndian: false.
self unsignedLongAt: index+4 put: (val bitShift: -32) bigEndian: false.

Thanks for finding this!


best, Eliot
