• Add __builtin_elementwise_popcount builtin for integer types only.
• Add __builtin_elementwise_fmod builtin for floating point types only.
• Add __builtin_elementwise_minimum and __builtin_elementwise_maximum builtin for floating point types only.
• The builtin type alias __builtin_common_type has been added to improve the performance of std::common_type.

PVS-Studio 7.34: support for Apple Silicon ARM64, CodeChecker

by Aleksandra Uvarova

From the article:

New diagnostic rules. C, C++:

• V1116. Creating an exception object without an explanatory message may result in insufficient logging.
• V1117. The declared function type is cv-qualified. The behavior when using this type is undefined.
• V2022. Implicit type conversion from integer type to enum type.
• V5014. OWASP. Cryptographic function is deprecated. Its use can lead to security issues. Consider switching to an equivalent newer function.
