# tests for exception-handling support
# Written by Satish Pai <pai@apollo.hp.com> 1997-07-23

# This file is part of the gdb testsuite

# Note: These tests are geared to the HP aCC compiler,
# which has an idiosyncratic way of emitting debug info
# for exceptions -- it uses a callback mechanism, which
# is different from the way g++ records exception info
# for debugging

# The tests are in two parts; the first part deals with
# statically linked (archive-bound) executables, and the
# second part repeats those tests with dynamically linked
# (shared bound) executables.  (In the latter case we use
# a different mechanism to get the address of the notification
# hook in the C++ support library.) The tests themselves are
# the same in both parts.
# 
# IMPORTANT:
# ---------
# IF YOU CHANGE A TEST IN ONE PART MAKE SURE YOU CHANGE IT
# --------------------------------------------------------
# IN THE OTHER PART TOO!
