A definition kills its own incoming operand use · case 05
A definition kills its own incoming operand use.
Case contract
Return sorted live-in variables for one instruction: uses union (live-out minus definitions). Uses occur before this instruction writes definitions.
Why this case matters
A deterministic offline analysis model exposing a specific soundness or precision boundary; it does not implement a complete language analyzer.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
