  21 # tests for exception-handling support
  22 # Written by Satish Pai <pai@apollo.hp.com> 1997-07-23
  23
  24 # This file is part of the gdb testsuite
  25
  26 # Note: These tests are geared to the HP aCC compiler,
  27 # which has an idiosyncratic way of emitting debug info
  28 # for exceptions -- it uses a callback mechanism, which
  29 # is different from the way g++ records exception info
  30 # for debugging
  31
  32 # The tests are in two parts; the first part deals with
  33 # statically linked (archive-bound) executables, and the
  34 # second part repeats those tests with dynamically linked
  35 # (shared bound) executables.  (In the latter case we use
  36 # a different mechanism to get the address of the notification
  37 # hook in the C++ support library.) The tests themselves are
  38 # the same in both parts.
  39 #
  40 # IMPORTANT:
  41 # ---------
  42 # IF YOU CHANGE A TEST IN ONE PART MAKE SURE YOU CHANGE IT
  43 # --------------------------------------------------------
  44 # IN THE OTHER PART TOO!
