- Merge Assignment_3_Helper.{cpp,h,py} into AEReporter.{cpp,h,py}; Helper
files removed.
- Move harness-only state (analyzedNodes / assert_points / caseConfig /
cycleHeadToCycle*) and metric methods (getAnalyzedNodeCount,
getTotalNodeCount, getICFGCoverage, hasTargetReport, writeJsonSummary)
out of AbstractExecution into AEReporter; expose AbstractExecution::
getReporter() for the test driver. *cycleHeadToCycle was dead and is
dropped entirely.
- Drop Ass3StateManager class; fold the 11 state-manager primitives
(getAbsValue / updateAbsValue / loadValue / storeValue / getGepObjAddrs /
getGepElementIndex / getGepByteOffset / getAllocaInstByteSize) into
AbstractExecution; student code now calls them as bare methods.
- Replace the old OVERFLOW stub with the SAFE/UNSAFE_BUFACCESS and
SAFE/UNSAFE_PTRDEREF checkpoint stubs throughout (handleCallSite,
handleStubFunctions, handleCheckpointStubs, isExternalCallForAssignment,
ensureAllAssertsValidated). Checkpoints now record their call sites in
assert_points so coverage is verified.
- Replace the dynamic `_funcsInFlight` recursion guard in handleFunction
with the static `inSameCallGraphSCC` check in handleCallSite, mirroring
SVF's AbstractInterpretation::skipRecursiveCall.
- Update public test cases to match the new stub names: null_deref now
calls UNSAFE_PTRDEREF (was UNSAFE_LOAD); buf_overflow now declares its
out-of-bounds write with UNSAFE_BUFACCESS.
- Update file headers from "buffer overflow detection" to "bug detection".
