# Test -symbol-info-functions, -symbol-info-variables, and

# -symbol-info-types.
|
|
#
|
|
# These tests can generate large amounts of output, which can cause gdb to be
|
|
# slow in two different ways:
|
|
# - it takes long before the command starts producing output
|
|
# - it takes long to print all the output
|
|
# We can prevent timeouts due to the latter using exp_continue, but for
|
|
# the former that doesn't work. There we use with_timeout_factor instead.
