Argyrios Kyrtzidis 735e92c29a [libclang] Introduce a new parsing option 'CXTranslationUnit_SingleFileParse' that puts preprocessor in a mode for parsing a single file only.
This is useful for parsing a single file, as a fast/inaccurate 'mode' that can still provide declarations from the file, like the classes and their methods.

Alexander Shaposhnikov 108ca94fa8 [clang] Fix format specifiers fixits
This diff fixes printf "fixits" in the case when there is 
a wrapping macro and the format string needs multiple replacements. 
In the presence of a macro there is an extra logic in EditedSource.cpp
to handle multiple uses of the same macro argument 
(see the old comment inside EditedSource::canInsertInOffset)
which was mistriggerred when the argument was used only once 
but required multiple adjustments), as a result the "fixit" 
was breaking down the format string
by dropping the second format specifier, i.e. 
Log1("test 4: %s %s", getNSInteger(), getNSInteger()) 
was getting replaced with 
Log1("test 4: %ld ", (long)getNSInteger(), (long)getNSInteger()) 
(if one removed the macro and used printf directly it would work fine).
In this diff we track the location where the macro argument is used and 
(as it was before) the modifications originating from all the locations 
except the first one are rejected, but multiple changes are allowed.

Test plan: make check-all

Serge Pavlov 79271ab154 Do not inherit default arguments for friend function in class template.
A function declared in a friend declaration may have declarations prior
to the containing class definition. If such declaration defines default
argument, the friend function declaration inherits them. This behavior
causes problems if the class where the friend is declared is a template:
during the class instantiation the friend function looks like if it had
default arguments, so error is triggered.

With this change friend functions declared in class templates do not
inherit default arguments. Actual set of them will be defined at the
point where the containing class is instantiated.

This change fixes PR12724.

Serge Pavlov 673f44c769 Improve diagnostics if friend function redefines file-level function.
Clang makes check for function redefinition after it merged the new
declaration with the existing one. As a result, it produces poor
diagnostics in the case of a friend function defined inline, as in
the code:
```
    void func() {}
    class C { friend void func() {} };
```
Error message in this case states that `inline declaration of 'func'
follows non-inline definition`, which is misleading, as `func` does
not have explicit `inline` specifier.

With this changes compiler reports function redefinition if the new
function is a friend defined inline and it does not have explicit
`inline` specifier.

Summary:
The thumb-mode target feature is used to force Thumb or ARM code
generation on a per-function basis. Explicitly adding +thumb-mode to
functions for thumbxx triples enables mixed ARM/Thumb code generation in
places where compilation units with thumbxx and armxx triples are merged
together (e.g. the IR linker or LTO).

For armxx triples, -thumb-mode is added in a similar fashion.

Richard Smith e6d4b773de Fix a couple of class template argument deduction crashes with libc++'s tuple.
RecursiveASTVisitor was not properly recursing through a
SubstTemplateTypeParmTypes, resulting in crashes in pack expansion where we
couldn't always find an unexpanded pack within a pack expansion.

We also have an issue where substitution of deduced template arguments for an
implicit deduction guide creates the "impossible" case of naming a
non-dependent member of the current instantiation, but within a specialization
that is actually instantiated from a different (partial/explicit)
specialization of the template. We resolve this by declaring that constructors
that do so can only be used to deduce specializations of the primary template.
I'm running this past CWG to see if people agree this is the right thing to do.

template is valid with or without it (with different meanings).

If we see "dependent.x<...", and what follows the '<' is a valid expression,
we must parse the '<' as a comparison rather than a template angle bracket.
When we later come to instantiate, if we find that the LHS of the '<' actually
names an overload set containing function templates, produce a diagnostic
suggesting that the 'template' keyword was missed rather than producing a
mysterious diagnostic saying that the function must be called (and pointing
at what looks to already be a function call!).

Summary:
This patch adds support for the target("arm") and target("thumb")
attributes, which can be used to force the compiler to generated ARM or
Thumb code for a function.

In LLVM, ARM or Thumb code generation can be controlled by the
thumb-mode target feature. But GCC already uses target("arm") and
target("thumb"), so we have to substitute "arm" with -thumb-mode and
"thumb" with +thumb-mode.

account for even more systems, just use [[RESOURCE_DIR]] like a number

Artem Dergachev 7c0ab86932 [analyzer] Don't add arrow to the inlined function's decl when it has no body.
In plist output mode with alternate path diagnostics, when entering a function,
we draw an arrow from the caller to the beginning of the callee's declaration.
Upon exiting, however, we draw the arrow from the last statement in the
callee function. The former makes little sense when the declaration is
not a definition, i.e. has no body, which may happen in case the body
is coming from a body farm, eg. Objective-C autosynthesized property accessor.
