Clang-tidy uses incorrect integer sizes when cross-compiling for baremetal arm #3061

Open glennvl opened 1 year ago

glennvl commented 1 year ago

Brief Issue Summary

When building for baremetal arm, clang-tidy shows warnings about size_t and unsigned long compatibilty. It appears that clang-tidy thinks the target system is 64-bit like the build system, while it is actually 32-bit.

Additional Information

The issue does not appear if set "C_Cpp.codeAnalysis.clangTidy.useBuildPath": true and manually add the compile commands location.

    "configurations": [
        {
            "name": "cmake",
            "compileCommands": "${workspaceFolder}/build/armv7hf-baremetal-gcc-debug/compile_commands.json",
            "configurationProvider": "ms-vscode.cmake-tools"
        }
    ],
    "version": 4

But the problem with this workaround is that the compile commands location depends on the cmake preset. So compileCommands would become ${command:cmake.buildDirectory}/compile_commands.json, which is not supported by c_cpp_properties.json.
