# tests for exception-handling support
# Written by Satish Pai <pai@apollo.hp.com> 1997-07-23
# Rewritten by Michael Chastain <mec.gnu@mindspring.com> 2004-01-08
# This file used to have two copies of the tests with different
# compiler flags for hp-ux. Instead, the user should set CXXOPTS
# or run runtest with --target_board unix/gdb:debug_flags="..."
# to choose the compiler flags.
#
# The interesting compiler flags are: "aCC +A -Wl,-a,-archive" .
# Static-linked executables use a different mechanism to get the
# address of the notification hook in the C++ support library.
# TODO: this file is not ready for production yet. If you are working
# on C++ exception support for gdb, you can take out the "continue"
# statement and try your luck. -- chastain 2004-01-09
# TODO: this file has many absolute line numbers.
# Replace them with gdb_get_line_number.

# continue to throw out of main

# The problem is that "re-throw" does not show a throw; only a catch.
# I do not know if this is because of a bug, or because the generated
# code is optimized for a throw into the same function.
