Eliot Miranda uploaded a new version of Tests to project The Trunk: http://source.squeak.org/trunk/Tests-eem.409.mcz
==================== Summary ====================
Name: Tests-eem.409 Author: eem Time: 19 March 2019, 11:38:09.260844 am UUID: 7ba5d6e0-5b70-462f-a1ee-c77ab5b74dc3 Ancestors: Tests-eem.408
DecompilerTests: Restrict the set of methods that are tested to thise in the base packages, excluding extensions from outside packages (this to eliminate errors due to _ assignment, etc). Beef up checkDecompileMethod: to deal with both OutOfScopeNotification and SyntaxErrorNotification when the decompiler wrongly converts a while loop into a to:do: when the index is used out of scope. Somehow the bytecode set affects which of these errors may be seen. Eliminate some cases that used to fail and no longer do (principally in ProtoObjectTest testIfNotNil et al). With these changes I see DecompilerTests all green in both 32-bit trunk and a trunk-derived 64-bit VMMaker image using SistaV1.
