[clang-tidy] Add a module for the Linux kernel.
Summary:
Now that clang is going to be able to build the Linux kernel again on
x86, and we have gen_compile_commands.py upstream for generating
compile_commands.json, clang-tidy can be used on the Linux kernel
source.
To that end, this commit adds a new clang-tidy module to be used for
checks specific to Linux kernel source. The Linux kernel follows its own
style of C, and it will be useful to separate those checks into their
own module.
This also adds an initial check that makes sure that return values from
the kernel error functions like PTR_ERR and ERR_PTR are checked. It also
makes sure that any functions that directly return values from these
functions are checked.

- New :doc:`linuxkernel-must-use-errs
|
|
|
|
|
<clang-tidy/checks/linuxkernel-must-use-errs>` check.
|
|
|
|
|
|
|
|
|
|
Checks Linux kernel code to see if it uses the results from the functions in
|
|
|
|
|
``linux/err.h``. Also checks to see if code uses the results from functions that
|
|
|
|
|
directly return a value from one of these error functions.
|
|
|
|
|
|
|
|
|
|
This is important in the Linux kernel because ``ERR_PTR``, ``PTR_ERR``,
|
|
|
|
|
``IS_ERR``, ``IS_ERR_OR_NULL``, ``ERR_CAST``, and ``PTR_ERR_OR_ZERO`` return
|
|
|
|
|
values must be checked, since positive pointers and negative error codes are
|
|
|
|
|
being used in the same context. These functions are marked with
|
|
|
|
|
``__attribute__((warn_unused_result))``, but some kernel versions do not have
|
|
|
|
|
this warning enabled for clang.

- New :doc:`google-upgrade-googletest-case

|
|
|
|
<clang-tidy/checks/google-upgrade-googletest-case>` check.
|
|
|
|
|
|
|
|
|
|
Finds uses of deprecated Googletest APIs with names containing ``case`` and
|
|
|
|
|
replaces them with equivalent APIs with ``suite``.

[clang-tidy] openmp-use-default-none - a new check
Summary:
Finds OpenMP directives that are allowed to contain `default` clause,
but either don't specify it, or the clause is specified but with the kind
other than `none`, and suggests to use `default(none)` clause.
Using `default(none)` clause changes the default variable visibility from
being implicitly determined, and thus forces developer to be explicit about the
desired data scoping for each variable.

[pp-trace] Delete -ignore and add a new option -callbacks
Summary:
-ignore specifies a list of PP callbacks to ignore. It cannot express a
whitelist, which may be more useful than a blacklist.
Add a new option -callbacks to replace it.
-ignore= (default) => -callbacks='*' (default)
-ignore=FileChanged,FileSkipped => -callbacks='*,-FileChanged,-FileSkipped'
-callbacks='Macro*' : print only MacroDefined,MacroExpands,MacroUndefined,...
