Description
The dead store elimination removes statements from for-loops which are actually critical, which causes the compiler to silently change the behaviour of algorithms. Calling generateSeparateCode on InstSection in the attached file causes the last statement in the for-loop (when_stmt_opt := SOME(when_stmt);) in InstSection.instStatement to be removed.
This is done in Patterm.statementFindDeadStore.

It doesn't make sense to keep closed ticket in the "Future" milestone that were simply forgotten to assign to the correct milestone in the past.
