The usage of clang-tidy, is pretty simple, you set the list of checks you want, the header on which you want to have warnings reported and the list of source files to analyse: clang-tidy -checks='*' -header-filter="^include" -p . I like this one because it forces me to fix warnings. Depending on use case, it may simply help with readability of the code, or in some cases, point to potential bugs which remain unnoticed due to implicit conversions. You can configure it when  clang-tidy is a clang-based C++ “linter” tool. Comments. ○ clang-cl is a cl.exe compatible driver mode for clang. Clang diagnostics are treated in a similar way as check diagnostics. Diagnostic flags in Clang, warning: 'objc_independent_class' attribute may be put on Objective-C object pointer type only; attribute is warning: uninitialized variable in a constexpr  The uninitialized warning is done by a simple analysis of the source, is there an assignment before the first use? workaround exists .

Clang definitely can't compile UE on Windows at the moment, and I don't think it ever has been able to in the past [edit: this is incorrect, see DarkVeil's post from 01-05-2015 above - around UE 4.7 it was possible to compile in monolithic debug mode with Clang 3.7]. Here is code that handles this case:  In clang we can ignore warnings as described here. To discover the Clang diagnostics benefits, let’s compile a minimal C++ source code with both Visual C++ and Clang, and compare between the warnings reported. The following sections list the warnings introduced by each version of Visual C++ that you can suppress by using the /Wv compiler option. -O2 Moderate level of optimization which enables most optimizations. A few years after this site's launch in June 2014, the Clang project added a comprehensive list of diagnostics to their documentation, making this project unnecessary.. When targeting Windows with the MSVC-compatible clang-cl driver, some of the details are different. @Antoine's answer (and the other question linked) accurately describe the LLVM optimizations that are enabled, but there are a few other Clang-specific options (i.e., those that affect lowering to the AST) that affected by the -O[0|1|2|3|fast] flags. Diagnostic text: warning: implicit truncation from C  the compiler warns about implicit conversion (using -Wall and -std=c++14) as following: warning: implicit conversion from 'const long' to 'int' changes value from 4294967296 to 0 [-Wconstant-conversion] which is ok. The converter is also capable of transforming iterator loops which use rbegin and rend for looping backwards over a container. ... Edit Web IDE.
