While investigating another issue, I noticed that `MaybeReexec()` never actually "re-executes via `execv()`" anymore. `DyldNeedsEnvVariable()` only returned true on macOS 10.10 and below. Usually, I try to avoid "unnecessary" cleanups (it's hard to be certain that there truly is no fallout), but I decided to do this one because: * I initially tricked myself into thinking that `MaybeReexec()` was relevant to my original investigation (instead of being dead code). * The deleted code itself is quite complicated. * Over time a few other things were mushed into `MaybeReexec()`: initializing `MonotonicNanoTime()`, verifying interceptors are working, and stripping the `DYLD_INSERT_LIBRARIES` env var to avoid problems when forking. * This platform-specific thing leaked into `sanitizer_common.h`. * The `ReexecDisabled()` config nob relies on the "strong overrides weak pattern", which is now problematic and can be completely removed. * `ReexecDisabled()` actually hid another issue with interceptors not working in unit tests. I added an explicit `verify_interceptors` (defaults to `true`) option instead. Differential Revision: https://reviews.llvm.org/D129157 |
