# This test validates that statistics generation does not force loading
|
|
# symbol tables. In order to avoid other sources of symbol loading we
|
|
# create the target without loading dependents and do not actually
|
|
# run it. Running the target is a problem because there are various
|
|
# instrumentation plugins (e.g. ASAN) that are always enabled and force
|
|
# symbol loading. If you see this test start to fail we may have added
|
|
# a new source of symbol loading unexpectedly.

# Build a simple test executable.
