The diagnostics are issued whenever the aligned functions are selected

If there is a user-defined function available somewhere else, option

This patch extends the `overloadable` attribute to allow for one
function with a given name to not be marked with the `overloadable`
attribute. The overload without the `overloadable` attribute will not
have its name mangled.
So, the following code is now legal:
void foo(void) __attribute__((overloadable));
void foo(int);
void foo(float) __attribute__((overloadable));
In addition, this patch fixes a bug where we'd accept code with
`__attribute__((overloadable))` inconsistently applied. In other words,
we used to accept:
void foo(void);
void foo(void) __attribute__((overloadable));
But we will do this no longer, since it defeats the original purpose of
requiring `__attribute__((overloadable))` on all redeclarations of a
function.
This breakage seems to not be an issue in practice, since the only code
I could find that had this pattern often looked like:
void foo(void);
void foo(void) __attribute__((overloadable)) __asm__("foo");
void foo(int) __attribute__((overloadable));
...Which can now be simplified by simply removing the asm label and
overloadable attribute from the redeclaration of `void foo(void);`

Prior to r297702, the starting position information was not being

The crash occurs when there is a template parameter list in a class that

class C0 {
public:
template<typename T, typename T1 = T // missing closing angle bracket
struct S0 {};
C0() : m(new S0<int>) {}

};
This happens because the parsed struct is added to the scope of the
enclosing class without having its access specifier set, which results
in an assertion failure in SemaAccess.cpp later.
This commit fixes the crash by adding the parsed struct to the enclosing
file scope and marking structs as invalid if they are defined in
template parameter lists.

2 | if (...) {
3 | return expr_which_might_evaluate_to_null();
4 | } else {
5 | return another_expr_which_might_evaluate_to_null();
6 | }
7 |} // <- The current diagnostic always points here!
runtime error: Null returned from Line 7, Column 2!
With this patch, the diagnostic would point to either Line 3, Column 5
or Line 5, Column 5.
This is done by emitting source location metadata for each return
statement in a sanitized function. The runtime is passed a pointer to
the appropriate metadata so that it can prepare and deduplicate reports.

(possible implicit) noexcept specifier
Throwing in the destructor is not good (C++11 change try to not allow see below).
But in reality, those codes are exist.
C++11 [class.dtor]p3:
A declaration of a destructor that does not have an exception-specification is
implicitly considered to have the same exception specification as an implicit
declaration.
With this change, the application worked before may now run into runtime
termination. My goal here is to emit a warning to provide only possible info to
where the code may need to be changed.
First there is no way, in compile time to identify the “throw” really throw out
of the function. Things like the call which throw out… To keep this simple,
when “throw” is seen, checking its enclosing function(only destructor and
dealloc functions) with noexcept(true) specifier emit warning.
Here is implementation detail:
A new member function CheckCXXThrowInNonThrowingFunc is added for class Sema
in Sema.h. It is used in the call to both BuildCXXThrow and
TransformCXXThrowExpr.
The function basic check if the enclosing function with non-throwing noexcept
specifer, if so emit warning for it.
The example of warning message like:
k1.cpp:18:3: warning: ''~dependent_warn'' has a (possible implicit) non-throwing
noexcept specifier. Throwing exception may cause termination.

-gz=none disable compression
-gz=zlib-gnu enable compression (deprecated GNU style zlib compression)
-gz=zlib enable compression (zlib based compression)
Although -Wa,-compress-debug-sections works, it should be discouraged
when using the driver to invoke the assembler. However, we permit the

*is* profile-guided optimization information, so the warning is misleading.
Furthermore, despite the warning, hotness was displayed based on the data in

add a test that verifies this.

declarations that are owned but unconditionally visible.
This allows us to set declarations as visible even if they have a local owning
module, without losing information. In turn, that means that our Objective-C
support can keep on incorrectly assuming the "hidden" bit on the declaration is
the whole story with regard to name visibility. This will also be useful once
we support the C++ Modules TS export semantics.
Objective-C name visibility is still incorrect in any case where the "hidden"
bit is not the complete story: for instance, in Objective-C++ the set of
visible categories will be wrong during template instantiation, and with local
submodule visibility enabled it will be wrong when building modules. Fixing that
will require a major overhaul of how visibility is handled for Objective-C (and

section. Additionally, it corrects the integer/int-pointer assignments. Unlike

While a function body is being parsed, the function declaration is not considered
as a definition because it does not have a body yet. In some cases it leads to
incorrect interpretation, the case is presented in
https://bugs.llvm.org/show_bug.cgi?id=14785:
```
template<typename T> struct Somewhat {
void internal() const {}
friend void operator+(int const &, Somewhat<T> const &) {}
};
void operator+(int const &, Somewhat<char> const &x) { x.internal(); }
```
When statement `x.internal()` in the body of global `operator+` is parsed, the type
of `x` must be completed, so the instantiation of `Somewhat<char>` is started. It
instantiates the declaration of `operator+` defined inline, and makes a check for
redefinition. The check does not detect another definition because the declaration
of `operator+` is still not defining as does not have a body yet.
To solves this problem the function `isThisDeclarationADefinition` considers
a function declaration as a definition if it has flag `WillHaveBody` set.

Summary:
Disable generation of counting-function attribute if no_instrument_function
attribute is present in function.
Interaction between -pg and no_instrument_function is the desired behavior
and matches gcc as well.
This is required for fixing a crash in Linux kernel when function tracing
is enabled.
Fixes PR33515.

In C++ all variables are in default address space. Previously change has been
made to cast automatic variables to default address space. However that is
not sufficient since all temporary variables need to be casted to default
address space.
This patch casts all temporary variables to default address space except those
for passing indirect arguments since they are only used for load/store.
This patch only affects target having non-zero alloca address space.
