[jira] Created: (HARMONY-4702) [drlvm][jit][opt] type merge for
stack vars in prepass is too restrictive
[drlvm][jit][opt] type merge for stack vars in prepass is too restrictive
-------------------------------------------------------------------------
Key: HARMONY-4702
URL: https://issues.apache.org/jira/browse/HARMONY-4702
Project: Harmony
Issue Type: Bug
Components: DRLVM
Environment: All
Reporter: Pavel Ozhdikhin
VarIncarnations of stack variables of different types are not merged at joining edges, even if their types are compatible. This may lead to incorrect promotion of the stack var to variable at some CFG point and to the crash during the compilation. The bug was caught on a complex Jython scenario with dynamic class generation.
