Jonas Toth 5c0f66b1fe [clang-tidy] fix check_clang_tidy to forbid mixing of CHECK-NOTES and CHECK-MESSAGES
Summary:
The check_clang_tidy.py script would allow mixing of `CHECK-NOTES` and `CHECK-MESSAGES` but running `FileCheck` for that would implicitly fail, because `CHECK-NOTES` bails out if there is a warning.

That means a clang-tidy test can not mix these constructs to check warnings with `CHECK-MESSAGES` and notes with `CHECK-NOTES`. The script gives now a clear error if that happens.

Roman Lebedev 70fcafc096 [clang-tidy] check_clang_tidy.py: support CHECK-NOTES prefix
Summary:
Currently, there is two configured prefixes: `CHECK-FIXES` and `CHECK-MESSAGES`
`CHECK-MESSAGES` checks that there are no test output lines with `warning:|error:`, which are not explicitly handled in lit tests.
However there does not seem to be a nice way to enforce for all the `note:` to be checked.
This was useful for me when developing D36836.

Zinovy Nis eba2857bed [clang-tidy] Customize FileCheck prefix in check_clang-tidy.py
The patch introduces a new command line option '-check-suffix' for check_clang_tidy.py 
to allow multiple %check_clang_tidy% in a single test file.

Sample:

// RUN: %check_clang_tidy -check-suffix=FLAG-1 %s misc-unused-using-decls %t -- -- <options-set-1>
// RUN: %check_clang_tidy -check-suffix=FLAG-2 %s misc-unused-using-decls %t -- -- <options-set-2> 
...
+// CHECK-MESSAGES-FLAG-1: :[[@LINE-4]]:10: warning: using decl 'B' is unused [misc-unused-using-decls]
+// CHECK-MESSAGES-FLAG-2: :[[@LINE-7]]:10: warning: using decl 'A' is unused [misc-unused-using-decls]
+// CHECK-FIXES-FLAG-1-NOT: using a::A;$
+// CHECK-FIXES-FLAG-2-NOT: using a::B;$

Haojian Wu 9e0f7f1a23 Support Objective-C/C++ source files in check_clang_tidy.py
check_clang_tidy.py currently only handles C and C++ source files.

This extends the logic to also handle Objective-C (.m) and
Objective-C++ (.mm) files.

However, by default, clang compiles .m/.mm files using Objective-C 1.0
syntax. Objective-C 2.0 has been the default in Xcode for about 10
years, and Objective-C Automatic Reference Counting (ARC) for about 6
years, so this enables both by default.

(Clients which actually want to test clang-tidy checks for Objective-C
 1.0 or non-ARC files can pass custom flags to check_clang_tidy.py
 after --, which will disable the Objective-C 2.0 and ARC flags).

I did not add logic to handle running clang-tidy on Objective-C header
files alone; they also use the .h file extension, so we'd need to
look inside their contents.

I included a new test to confirm the new behavior.

Depends On D38963

Haojian Wu a08422e0e4 New -assume-filename=param to check_clang_tidy.py (like clang-format)
Summary:
Currently, check_clang_tidy.py includes logic to select default
clang flags based on the extension of the source filename passed
as the first argument.

Since the source filename might be a temporary or test file with an
arbitrary extension unrelated to the file type, this adds the ability
to override the logic the same way `clang-format`'s -assume-filename=
parameter does.

I included a test with a nonstandard file extension. I confirmed
when I modified the warning message that the new test failed,
and that it passed again when I restored the warning message.

Ran tests with:

% cmake -G Ninja /path/to/llvm
% ninja check-clang-tools

Alexander Kornienko e04dd2525c [clang-tidy] Python scripts shebang fixes
Summary:
This patch fixes shebang lines in Python script files.

Most Python scripts in LLVM & Clang are using this shebang line.

[[ https://mail.python.org/pipermail/tutor/2007-June/054816.html | Here]] is an explanaiton of why such line should be used instead of what is currently in these few files.

non-standard locations for builtin includes.

Summary:
Add check_clang_tidy.py script that is functionally identical to the

I've verified that the script works on linux. Would be nice if folks using
Windows could test the patch before I break windows bots ;)
