◆ MacroUsageCheck()

Member Function Documentation

◆ registerPPCallbacks()

void clang::tidy::cppcoreguidelines::MacroUsageCheck::registerPPCallbacks ( CompilerInstance &  Compiler)
overridevirtual

Override this to register PPCallbacks with Compiler.

This should be used for clang-tidy checks that analyze preprocessor- dependent properties, e.g. the order of include directives.

Reimplemented from clang::tidy::ClangTidyCheck.

Definition at line 71 of file MacroUsageCheck.cpp.

◆ storeOptions()

void clang::tidy::cppcoreguidelines::MacroUsageCheck::storeOptions ( ClangTidyOptions::OptionMap Options)
overridevirtual

Should store all options supported by this check with their current values or default values for options that haven't been overridden.

The check should use Options.store() to store each option it supports whether it has the default value or it has been overridden.

Reimplemented from clang::tidy::ClangTidyCheck.

◆ warnMacro()

void clang::tidy::cppcoreguidelines::MacroUsageCheck::warnMacro ( const MacroDirective *  MD,
StringRef  MacroName 
)

A variadic macro is function-like at the same time. Therefore variadic macros are checked first and will be excluded for the function-like diagnostic.

◆ warnNaming()

void clang::tidy::cppcoreguidelines::MacroUsageCheck::warnNaming ( const MacroDirective *  MD,

)
