For out-of-bounds checking of static 96e566bc5SRichardarrays, see the `-Warray-bounds` Clang diagnostic. 106e566bc5SRichard 11*0f1f1d45SPiotr ZegarThis rule is part of the `Bounds safety (Bounds 2) 12*0f1f1d45SPiotr Zegar<https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Pro-bounds-arrayindex>`_ 13*0f1f1d45SPiotr Zegarprofile from the C++ Core Guidelines. 146e566bc5SRichard 156e566bc5SRichardOptionally, this check can generate fixes using ``gsl::at`` for indexing. 166e566bc5SRichard 176e566bc5SRichardOptions 186e566bc5SRichard------- 196e566bc5SRichard 206e566bc5SRichard.. option:: GslHeader 216e566bc5SRichard 226e566bc5SRichard The check can generate fixes after this option has been set to the name of 236e566bc5SRichard the include file that contains ``gsl::at()``, e.g. `"gsl/gsl.h"`. 246e566bc5SRichard 256e566bc5SRichard.. option:: IncludeStyle 266e566bc5SRichard 276e566bc5SRichard A string specifying which include-style is used, `llvm` or `google`.
