  21 # tests for exception-handling support
  22 # Written by Satish Pai <pai@apollo.hp.com> 1997-07-23
  23 # Rewritten by Michael Chastain <mec.gnu@mindspring.com> 2004-01-08

  25 # This file used to have two copies of the tests with different
  26 # compiler flags for hp-ux.  Instead, the user should set CXXOPTS
  27 # or run runtest with --target_board unix/gdb:debug_flags="..."
  28 # to choose the compiler flags.
  29 #
  30 # The interesting compiler flags are: "aCC +A -Wl,-a-archive" .
  31 # Static-linked executables use a different mechanism to get the
  32 # address of the notification hook in the C++ support library.
  33
  34 # TODO: this file is not ready for production yet.  If you are working
  35 # on C++ exception support for gdb, you can take out the "continue"
  36 # statement and try your luck.  -- chastain 2004-01-09

 216 #    continue to throw out of main
 217 #

 219 # I do not know if this is because of a bug, or because the generated
 220 # code is optimized for a throw into the same function.
