Name: Tests-eem.408 Author: eem Time: 19 March 2019, 9:29:58.589612 am UUID: 98f708d3-76ec-4f02-9db0-8472e0e09a25 Ancestors: Tests-pre.407
Fix a couple of failing Compiler tests. testPCPreviousTo must be made aware of extensions, for the SistaV1 bytecode set. testMaxLiteralsWithClassReferenceInClosure must adapt to the much greater number of literals available in the SistaV1 set.
