  • The removal of FinalizerBase and consolidation into KickOff for both thread types is clear dead code deletion. Please ensure relevant tests cover the finalizer thread behavior to verify that exception handling and thread kickoff work as expected.
void ManagedThreadBase::KickOff(ADCallBackFcnType pTarget, LPVOID args)

src/coreclr/vm/excep.cpp:4541

  • The call to DefaultCatchHandler has been modified to remove the 'isThreadBaseFilter' and 'sendAppDomainEvents' parameters. Ensure that this change aligns with the new function interface and that the expected exception event handling behavior is maintained.
DefaultCatchHandler(pParam->pExceptionInfo, NULL, useLastThrownObject, TRUE /* sendWindowsEventLog */);

src/coreclr/vm/ceeload.cpp:489

  • The removal of the DACCESS_COMPILE guard around the initialization of m_pJitInlinerTrackingMap is observed. Confirm that this change is intentional and that it does not affect builds targeting DACCESS.
#if !defined(DACCESS_COMPILE)

src/coreclr/vm/appdomain.hpp:1148

  • Changing the signature of OnUnhandledException from returning BOOL to void is a breaking change. Verify that all call sites have been updated to accommodate the new signature and that behavior remains consistent.

This was always called with swallowing = true, so the rest of this method is dead code. The small piece from the above (ExceptionIsAlwaysSwallowed check) was folded into the caller.

src/coreclr/vm/threads.cpp:7158

  • The removal of FinalizerBase and consolidation into KickOff for both thread types is clear dead code deletion. Please ensure relevant tests cover the finalizer thread behavior to verify that exception handling and thread kickoff work as expected.
void ManagedThreadBase::KickOff(ADCallBackFcnType pTarget, LPVOID args)

src/coreclr/vm/excep.cpp:4541

  • The call to DefaultCatchHandler has been modified to remove the 'isThreadBaseFilter' and 'sendAppDomainEvents' parameters. Ensure that this change aligns with the new function interface and that the expected exception event handling behavior is maintained.
DefaultCatchHandler(pParam->pExceptionInfo, NULL, useLastThrownObject, TRUE /* sendWindowsEventLog */);

src/coreclr/vm/ceeload.cpp:489

  • The removal of the DACCESS_COMPILE guard around the initialization of m_pJitInlinerTrackingMap is observed. Confirm that this change is intentional and that it does not affect builds targeting DACCESS.
#if !defined(DACCESS_COMPILE)

src/coreclr/vm/appdomain.hpp:1148

  • Changing the signature of OnUnhandledException from returning BOOL to void is a breaking change. Verify that all call sites have been updated to accommodate the new signature and that behavior remains consistent.
static void OnUnhandledException(OBJECTREF *pThrowable);

This was always called with swallowing = true, so the rest of this method is dead code. The small piece from the above (ExceptionIsAlwaysSwallowed check) was folded into the caller.
