Reland "Enable simulating errors to test fuzzer reliability"
This is a reland of 4ad08c82 The reland organizes the different error types in separate functions for separate call stacks. Error simulation is also guarded by a minimum file size to prevent Clusterfuzz from getting stuck with its bad-build check. Original change's description: > Enable simulating errors to test fuzzer reliability > > This adds a d8 flag --simulate-errors, which on shutdown will cause > certain errors. This enables testing the reliability of sanitizers. > > This will cause a fatal error, a dcheck (if available) or a > violation that can be detected with one of the following sanitizers: > ASAN, UBSAN, MSAN, CFI. > > The same flag used in differential fuzzing will cause an error > subsumed with the error state "fake_difference". > > Bug: chromium:1152412 > Change-Id: I4b36c6fe716797004d634263617d22ca67b05600 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2554999 > Commit-Queue: Michael Achenbach <machenbach@chromium.org> > Reviewed-by: Clemens Backes <clemensb@chromium.org> > Cr-Commit-Position: refs/heads/master@{#71430} Bug: chromium:1152412 Change-Id: I604258b4c1ebd215c26b1de6b2822663f857bf64 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2565125 Commit-Queue: Michael Achenbach <machenbach@chromium.org> Reviewed-by: Clemens Backes <clemensb@chromium.org> Cr-Commit-Position: refs/heads/master@{#71538}
