| # 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. |
| # RUN: %clang_host -g %S/Inputs/main.c -o %t-main.exe |
| |
| # When we enable symbol preload and dump stats there should be a non-zero |
| # time for parsing symbol tables for the main module. |
