Introduction ¶

This document contains the release notes for the Extra Clang Tools, part of the Clang release 10.0.0. Here we describe the status of the Extra Clang Tools in some detail, including major improvements from the previous release and new feature work. All LLVM releases may be downloaded from the LLVM releases web site.

For more information about Clang or LLVM, including information about the latest release, please see the Clang Web Site or the LLVM Web Site.

Note that if you are reading this file from a Subversion checkout or the main Clang web page, this document applies to the next release, not the current one. To see the release notes for a specific release, please see the releases page.

clang-doc now generates documentation in HTML format.

New bugprone-dynamic-static-initializers check.

Finds instances where variables with static storage are initialized dynamically in header files.
New bugprone-infinite-loop check.

Finds obvious infinite loops (loops where the condition variable is not changed at all).
New bugprone-not-null-terminated-result check

Finds function calls where it is possible to cause a not null-terminated result. Usually the proper length of a string is strlen(str) + 1 or equal length of this expression, because the null terminator needs an extra space. Without the null terminator it can result in undefined behaviour when the string is read.
New cppcoreguidelines-init-variables check.
New darwin-dispatch-once-nonstatic check.

Finds declarations of dispatch_once_t variables without static or global storage.
New google-upgrade-googletest-case check.

Finds uses of deprecated Googletest APIs with names containing case and replaces them with equivalent APIs with suite.
Improved hicpp-signed-bitwise check.

The check now supports the IgnorePositiveIntegerLiterals option.
New linuxkernel-must-use-errs check.

Checks Linux kernel code to see if it uses the results from the functions in linux/err.h.
New llvm-prefer-register-over-unsigned check.

Finds historical use of unsigned to hold vregs and physregs and rewrites them to use Register
New objc-missing-hash check.

Finds Objective-C implementations that implement -isEqual: without also appropriately implementing -hash.
New performance-trivially-destructible check.

Finds types that could be made trivially-destructible by removing out-of-line defaulted destructor declarations.
Improved bugprone-posix-return check.

Now also checks if any calls to pthread_* functions expect negative return values.
The ‘objc-avoid-spinlock’ check was renamed to darwin-avoid-spinlock
New readability-redundant-access-specifiers check.

Finds classes, structs, and unions that contain redundant member access specifiers.
