The Trunk: KernelTests-ul.400.mcz

commits-2
Nicolas Cellier uploaded a new version of KernelTests to project The Trunk:
http://source.squeak.org/trunk/KernelTests-ul.400.mcz

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

Name: KernelTests-ul.400
Author: ul
Time: 14 April 2021, 12:14:51.757056 pm
UUID: 6234d088-bf14-4d00-8734-dde043b756ba
Ancestors: KernelTests-nice.399

WriteBarrierTest changes:
- removed symbol mutator methods
        - both #testMutateByteSymbolUsingPrivateAtPut and #testMutateWideSymbolUsingPrivateAtPut reference a non-existent #privateAt:put: method, and make the accessed symbol permanently writeable
        - with the removal of #pvtAt:put: from ByteSymbol and WideSymbol, the tests seem to be unnecessary (see Collections-ul.939)
- fix copy-paste error in #testMutateObjectInstVarUsingBasicAtPut: test #basicAt:put: instead of #at:put:
- avoid having MirrorPrimitives in Undeclared by removing direct references to it in WriteBarrierTest. Perhaps MirrorPrimitives should be moved to the Trunk from VMMaker


- use temporaries in CompiledMethodComparisonTest >> #testHash to improve legibility
