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

 215 #    continue to throw out of main
 216 #

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