// jmpuwind.s
//
// Abstract:
//
// This module implements the MIPS specific routine to jump to the runtime
// time library unwind routine.

// David N. Cutler (davec) 12-Sep-1990
//
// Environment:
//
// Any mode.

// __C_ExecuteExceptionFilter (
// PEXCEPTION_POINTERS ExceptionPointers,
// EXCEPTION_FILTER ExceptionFilter,
// ULONG EstablisherFrame
// )
//
// Routine Description:
//
// This function sets the static link and transfers control to the specified
// exception filter routine.
//
// Arguments:
//
// ExceptionPointers (a0) - Supplies a pointer to the exception pointers
// structure.
//
// ExceptionFilter (a1) - Supplies the address of the exception filter
// routine.
//
// EstablisherFrame (a2) - Supplies the establisher frame pointer.
//
// Return Value:
//
// The value returned by the exception filter routine.

//
// This function sets the static link and transfers control to the specified
// termination handler routine.
//
// Arguments:
//
// AbnormalTermination (a0) - Supplies a boolean value that determines
// whether the termination is abnormal.
//
// TerminationHandler (a1) - Supplies the address of the termination handler
// routine.

//
// Routine Description:
//
// This function transfer control to unwind. It is used by the MIPS
// compiler when a goto out of the body or a try statement occurs.
//
// Arguments:
//
// EstablishFrame (a0) - Supplies the establisher frame point of the
// target of the unwind.
//
// TargetPc (a1) - Supplies the target instruction address where control
// is to be transfered to after the unwind operation is complete.
//
// Return Value:
//
// None.
