VM Maker: VMMaker.oscog-cb.2117.mcz

commits-2
 
ClementBera uploaded a new version of VMMaker to project VM Maker:
http://source.squeak.org/VMMaker/VMMaker.oscog-cb.2117.mcz

==================== Summary ====================

Name: VMMaker.oscog-cb.2117
Author: cb
Time: 31 January 2017, 2:41:26.404463 pm
UUID: b56c34a6-88ae-4f17-930a-fc625b7ab100
Ancestors: VMMaker.oscog-eem.2116

Fixed a bug in read-only object where the attemptToAssign:withIndex: call-back would be called with a 1-based index by the interpreter and 0-based index by the JIT. Everybody now calls it with 1-based index.

=============== Diff against VMMaker.oscog-eem.2116 ===============

Item was changed:
  ----- Method: CoInterpreter>>ceCannotAssignTo:withIndex:valueToAssign: (in category 'trampolines') -----
  ceCannotAssignTo: immutableObject withIndex: index valueToAssign: valueToAssign
+ "index is unboxed and 0-based. The call-back expects 1-based value (to perform the operation with instVarAt:put:"
- "index is unboxed."
