# 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
|
||
|
|
# --------------------------------------------------------
