[PATCH 4/4] check-block: Enable iotests with SafeStack |
Date: |
Wed, 29 Apr 2020 15:44:20 -0400 |
SafeStack is a stack protection technique implemented in llvm. It is
enabled with a -fsanitize flag.
iotests are currently disabled when any -fsanitize option is used.
Since SafeStack is useful on production environments, and its
implementation may break the binary, filter it out when the check is
performed, so that if SafeStack was the only -fsanitize option, iotests
are still performed.
