[jira] Commented: (HARMONY-3371) [drlvm][jit] Race condition at
vm\jitrino\src\jet\compiler.cpp
[ https://issues.apache.org/jira/browse/HARMONY-3371?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12480713 ]
Alex Astapchuk commented on HARMONY-3371:
-----------------------------------------
This particular notice is false alarm.
initProfilingData(unsinged* ) is only invoked from Compiler::compile()
to write into Compiler::compile()'s *local* variable.
There is no race here.

> There are thread unsafe access that result in race condition that occur during concurrent execution of enum JIT_Result Jitrino::Jet::Compiler::compile function.
> Write -> Write data-race
> Memory write at "compiler.cpp":119 conflicts with a prior memory write at "compiler.cpp":119 (L119: initProfilingData(&compile_flags))
