Shoaib Meenai d806af3499 [CMake] Use PRIVATE in target_link_libraries for executables
We currently use target_link_libraries without an explicit scope
specifier (INTERFACE, PRIVATE or PUBLIC) when linking executables.
Dependencies added in this way apply to both the target and its
dependencies, i.e. they become part of the executable's link interface
and are transitive.

Transitive dependencies generally don't make sense for executables,
since you wouldn't normally be linking against an executable. This also
causes issues for generating install export files when using
LLVM_DISTRIBUTION_COMPONENTS. For example, clang has a lot of LLVM
library dependencies, which are currently added as interface
dependencies. If clang is in the distribution components but the LLVM
libraries it depends on aren't (which is a perfectly legitimate use case
if the LLVM libraries are being built static and there are therefore no
run-time dependencies on them), CMake will complain about the LLVM
libraries not being in export set when attempting to generate the
install export file for clang. This is reasonable behavior on CMake's
part, and the right thing is for LLVM's build system to explicitly use
PRIVATE dependencies for executables.

Unfortunately, CMake doesn't allow you to mix and match the keyword and
non-keyword target_link_libraries signatures for a single target; i.e.,
if a single call to target_link_libraries for a particular target uses
one of the INTERFACE, PRIVATE, or PUBLIC keywords, all other calls must
also be updated to use those keywords. This means we must do this change
in a single shot. I also fully expect to have missed some instances; I
tested by enabling all the projects in the monorepo (except dragonegg),
and configuring both with and without shared libraries, on both Darwin
and Linux, but I'm planning to rely on the buildbots for other
configurations (since it should be pretty easy to fix those).

Even after this change, we still have a lot of target_link_libraries
calls that don't specify a scope keyword, mostly for shared libraries.
I'm thinking about addressing those in a follow-up, but that's a
separate change IMO.

Aaron Ballman d3d78b903a Add a new clang-tidy module for Fuchsia as an umbrella to diagnose issues with the Fuschia and Zircon coding guidelines (https://fuchsia.googlesource.com/zircon/+/master/docs/cxx.md). Adds the first of such checkers, which detects when default arguments are declared in a function declaration or when default arguments are used at call sites.

This allows to detect possible fixes using the parallelised run-clang-tidy.py

Yan Wang 36206206cd [clang-tidy][Part1] Add a new module Android and three new checks.
Summary:
A common source of security bugs is code that opens a file descriptors without using the O_CLOEXEC flag.  (Without that flag, an opened sensitive file would remain open across a fork+exec to a lower-privileged SELinux domain, leaking that sensitive data.).

Add a new Android module and one checks in clang-tidy.
-- open(), openat(), and open64() should include O_CLOEXEC in their flags argument. [android-file-open-flag]

Jakub Kuderski a7410fdbee [clang-tidy] run-clang-tidy.py: check if clang-apply-replacements succeeds
Summary:
When running run-clang-tidy.py with -fix it tries to apply found replacements at the end.
If there are errors running clang-apply-replacements, the script currently crashes or displays no error at all.

This patch checks for errors running clang-apply-replacements the same way clang-tidy binary is handled.

Another option would be probably checking for clang-apply-replacements (when -fix is passed) even before running clang-tidy.
