| // Ensure that we do not export any weak symbols from the dylibs. |
| // |
| // Weak symbols require additional work from the loader to resolve the symbol at |
| // load time and can cause ODR violations as well as unexpected symbol |
| // satisfaction because the weak symbol may be used from a separate module. |
| |
| // NOTE: this test is fragile. It is dependent on the specifics of the GNU C++ |
| // runtime. The C++ headers from the runtime explicitly force the weak symbols |
| // to be publicly visible without allowing the user to control the visibility. |
| // We explicitly filter out the ones that we see being leaked after manually |
| // validating that they are being leaked because of the forceful nature of |
| // libstdc++. |
