Note that https://clang-analyzer.llvm.org/scan-build.html is another llvm-based static analyzer.

It does a more deep analysis into the control flow, whereas clang-tidy does (mostly?) comparatively simpler checks on the AST.

I only hear about PVS-Studio from their adticles that they agressively post to programming-related communities.

Clang has support for cross-compiling [1] without needing separate builds for each target so you should be able to use clang-analyzer and clang-tidy whit the right -target flag for your ARM platform.

Besides that, most bugs found by static analysis are platform independent so you should be able to use any static analyzer you get your hands on as long as your code is cross-platform.

You can also get run-time checks in libstdc++ and libc++ with -D_GLIBCXX_DEBUG -D_GLIBCXX_DEBUG_PEDANTIC and -D_LIBCPP_DEBUG=1.
