-//------------------------------ generate_exception_blob ---------------------------
-// creates exception blob at the end
-// Using exception blob, this code is jumped from a compiled method.
-// (see emit_exception_handler in sparc.ad file)
-//
-// Given an exception pc at a call we call into the runtime for the
-// handler in this method. This handler might merely restore state
-// (i.e. callee save registers) unwind the frame and jump to the
-// exception handler for the nmethod if there is no Java level handler
-// for the nmethod.
-//
-// This code is entered with a jmp.
-//
-// Arguments:
-//   O0: exception oop
-//   O1: exception pc
-//
-// Results:
-//   O0: exception oop
-//   O1: exception pc in caller or ???
-//   destination: exception handler of caller
-//
-// Note: the exception pc MUST be at a call (precise debug information)
