18# tests for exception-handling support

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.

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
