  21 # This file used to have two copies of the tests with different
  22 # compiler flags for hp-ux.  Instead, the user should set CXXOPTS
  23 # or run runtest with --target_board unix/gdb:debug_flags="..."
  24 # to choose the compiler flags.
  25 #
  26 # The interesting compiler flags are: "aCC +A -Wl,-a,-archive" .
  27 # Static-linked executables use a different mechanism to get the
  28 # address of the notification hook in the C++ support library.

 221 #

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