PR12713 - crash on invalid due to unmatched parens in decltype

When template deduction fails on a derived class, try a template dedu…
…ction on

the base class.  If the base class deduction succeeds, use those results.  If
it fails, keep using the results from the derived class template deduction.

This prevents an assertion later where the type of deduction failure doesn't
match up with the template deduction info.

Dmitri Gribenko Force C89 for c-index-test.c
MSVC supports only C89, so it is important to keep c-index-test.c
buildable with C89.  However, Clang defaults to C99, so while building
Clang with Clang one can introduce C99 constructs into c-index-test.c
without noticing.

Thanks to Nakamura Takumi for helping with MSVC bits.

Benjamin Kramer Set TLSSupported to false on Haiku.
Haiku does not support this (yet). Leaving it set to true leads to
configure scripts detecting __thread being available and Clang emitting
code for it, resulting in binaries the runtime_loader will refuse to
load.

Fix a bug I found while preparing my devmtg talk: When passing NULL to a
function that takes a const Foo&, where Foo is convertible from a large number
of pointer types, we print ALL the overloads, no matter the setting of
-fshow-overloads.

There is potential follow-on work in unifying the "print candidates, but not
too many" logic between OverloadCandidateSet::NoteCandidates and
ImplicitConversionSequence::DiagnoseAmbiguousConversion.

[analyzer] When invalidating symbolic offset regions, take fields int…
…o account.

Previously, RegionStore was being VERY conservative in saying that because
p[i].x and p[i].y have a concrete base region of 'p', they might overlap.
Now, we check the chain of fields back up to the base object and check if
they match.

This only kicks in when dealing with symbolic offset regions because
RegionStore's "base+offset" representation of concrete offset regions loses
all information about fields. In cases where all offsets are concrete
(s.x and s.y), RegionStore will already do the right thing, but mixing
concrete and symbolic offsets can cause bindings to be invalidated that
are known to not overlap (e.g. p[0].x and p[i].y).
This additional refinement is tracked by <rdar://problem/12676180>.

Ted Kremenek Disable -Wimplicit-fallthrough when not using C++.
The rationale is that there is no good workflow to silence the warning
for specific cases, other than using pragmas.  This is because the
attribute to decorate an explicit fall through is only available
in C++11.

By that argument, this should probably also be disabled unless one
is using C++11, but apparently there is an explicit test case for
this warning when using C++98.  This will require further discussion
on cfe-commits.

djasper Fix binding of nodes in case of forEach..() matchers.
When recursively visiting the generated matches, the aggregated bindings need
to be copied during the recursion. Otherwise, we they might not be properly
overwritten (which is shown by the test), or there might be bound nodes present
that were bound on a different matching branch.

kind of warning.  For now, restrict this warning to C++11 (where an

the analyzer - when the runtime declaration is different from the static

Document this explicitly in the code (by adding a helper). Also, use
canonical Decls to avoid matching against the case where the definition
is different from found declaration.

Ted Kremenek Fix bad CFG construction bug when handling C++ 'try' statements.
This code assigned the last created CFGBlock* to the variable 'Block',
which is a scratch variable which is null'ed out after a block is
completed.  By assigning the last created block to 'Block', we start
editing a completed block, inserting CFGStmts that should be in
another block.  This was the case with 'try'.  The test case that
showed this had a while loop inside a 'try', and the logic before
the while loop was being included as part of the "condition block"
for the loop.  This showed up as a bogus dead store, but could
have lots of implications.

Turns out this bug was replicated a few times within CFG.cpp, so
I went and fixed up those as well.

Integer literal mangling does not actually depend on exact type of the literal.
This will simplify calling mangleIntegerLiteral when literal type is not known,

Also, call mangleNumber instead of directly printing mangled values of 0/1, to
avoid this knowledge from being in multiple places.

rjmccall Accept and pass arguments to __unknown_anytype in argument
positions of Objective-C methods.

It is possible to recover a lot of type information about
Objective-C methods from the reflective metadata for their
implementations.  This information is not rich when it
comes to struct types, however, and it is not possible to
produce a type in the debugger's round-tripped AST which
will really do anything useful during type-checking.
Therefore we allow __unknown_anytype in these positions,
which essentially disables type-checking for that argument.
We infer the parameter type to be the unqualified type of
the argument expression unless that expression is an
explicit cast, in which case it becomes the type-as-written
of that cast.

Provide the correct mangling and linkage for certain unnamed nested c…

This corrects the mangling and linkage of classes (& their member functions) in
cases like this:

  struct foo {
    struct {
      void func() { ... }
    } x;
  };

we were accidentally giving this nested unnamed struct 'no' linkage where it
should've had the linkage of the outer class. The mangling was incorrecty too,
mangling as TU-wide unnamed type mangling of $_X rather than class-scoped
mangling of UtX_.

This also fixes -Wunused-member-function which would incorrectly diagnose
'func' as unused due to it having no linkage & thus appearing to be TU-local
when in fact it might be correctly used in another TU.

Similar mangling should be applied to function local classes in similar cases
but I've deferred that for a subsequent patch.

Suppress elided variadic macro argument extension diagnostic for macr…
…os using

the related comma pasting extension.

In certain cases, we used to get two diagnostics for what is essentially one
extension.  This change suppresses the first diagnostic in certain cases
where we know we're going to print the second diagnostic.  The
diagnostic is redundant, and it can't be suppressed in the definition
of the macro because it points at the use of the macro, so we want to
avoid printing it if possible.

The implementation works by detecting constructs which look like comma
pasting at the time of the definition of the macro; this information
is then used when the macro is used.  (We can't actually detect
whether we're using the comma pasting extension until the macro is
actually used, but we can detecting constructs which will be comma
pasting if the varargs argument is elided.)

[analyzer] Make sure calls in synthesized functions have valid path l…
…ocations.

We do this by using the "most recent" good location: if a synthesized
function 'A' calls another function 'B', the path notes for the call to 'B'
will be placed at the same location as the path note for calling 'A'.

Similarly, the call to 'A' will have a note saying "Entered call from...",
and now we just don't emit that (since the user doesn't have a body to look
at anyway).

Previously, we were doing this for the "Calling..." notes, but not for the
"Entered call from..." or "Returning to caller". This caused a crash when
the path entered and then exiting a call within a synthesized body.

[analyzer] Mark symbol values as dead in the environment.
This allows us to properly remove dead bindings at the end of the top-level
stack frame, using the ReturnStmt, if there is one, to keep the return value
live. This in turn removes the need for a check::EndPath callback in leak
checkers.

This does cause some changes in the path notes for leak checkers. Previously,
a leak would be reported at the location of the closing brace in a function.
Now, it gets reported at the last statement. This matches the way leaks are
currently reported for inlined functions, but is less than ideal for both.

[analyzer] Report leaks at the closing brace of a function body.
This fixes a few cases where we'd emit path notes like this:

  +---+
 1|   v
  p = malloc(len);
  ^   |2
  +---+

In general this should make path notes more consistent and more correct,
especially in cases where the leak happens on the false branch of an if
that jumps directly to the end of the function. There are a couple places
where the leak is reported farther away from the cause; these are usually
cases where there are several levels of nested braces before the end of
the function. This still matches our current behavior for when there /is/
a statement after all the braces, though.

[analyzer] Fix a use-after-free introduced in r168019.
In code like this:

void foo() {
     bar();
     baz();
}

...the location for the call to 'bar()' was being used as a backup location
for the call to 'baz()'. This is fine unless the call to 'bar()' is deemed
uninteresting and that part of the path deleted.

(This looks like a logic error as well, but in practice the only way 'baz()'
could have an invalid location is if the entire body of 'foo()' is
synthesized, meaning the call to 'bar()' will be using the location of the
call to 'foo()' anyway. Nevertheless, the new version better matches the
intent of the code.)

Richard Smith A step towards sorting out handling of triviality of special members …
…in C++11.

Separate out the notions of 'has a trivial special member' and 'has a
non-trivial special member', and use them appropriately. These are not
opposites of one another (there might be no special member, or in C++11 there
might be a trivial one and a non-trivial one). The CXXRecordDecl predicates
continue to produce incorrect results, but do so in fewer cases now, and
they document the cases where they might be wrong.

No functionality changes are intended here (they will come when the predicates
start producing the right answers...).

Fix PR14321, a crash when Clang is built with GCC 4.7 at -O1 or greater.
GCC 4.7 reuses stack slots fairly aggressively, which exposes more temporary
lifetime bugs.

No new test, this was caught by the existing CodeGenCXX/mangle-ms-templates.cpp.

djasper Fix partial-match-bind-behavior with forEachDescendant() matchers.
The problem is that a partial match of an (explicit or implicit) allOf matcher
binds results, i.e.

recordDecl(decl().bind("x"), hasName("A"))

can very well bind a record that is not named "A". With this fix, the common
cases of stumbling over this bug are fixed by the BoundNodesMap overwriting the
results of a partial match. An error can still be created with a weird
combination of anyOf and allOf (see inactive test). We need to decide whether
this is worth fixing, as the fix will have performance impact.

common LexStringLiteral function.  In doing so, some consistency problems have
been ironed out (e.g. where the first token in the string literal was lexed

LexStringLiteral is complemented by a FinishLexStringLiteral function which
can be used in the situation where the first token of the string literal has
already been lexed.

Chandler Carruth Completely re-work how the Clang driver interprets PIC and PIE options.
There were numerous issues here that were all entangled, and so I've
tried to do a general simplification of the logic.
1) The logic was mimicing actual GCC bugs, rather than "features". These
   have been fixed in trunk GCC, and this fixes Clang as well. Notably,
   the logic was always intended to be last-match-wins like any other
   flag.
2) The logic for handling '-mdynamic-no-pic' was preposterously unclear.
   It also allowed the use of this flag on non-Darwin platforms where it
   has no actual meaning. Now this option is handled directly based on
   tests of how llvm-gcc behaves, and it is only supported on Darwin.
3) The APIs for the Driver's ToolChains had the implementation ugliness
   of dynamic-no-pic leaking through them. They also had the
   implementation details of the LLVM relocation model flag names
   leaking through.
4) The actual results of passing these flags was incorrect on Darwin in
   many cases. For example, Darwin *always* uses PIC level 2 if it uses
   in PIC level, and Darwin *always* uses PIC on 64-bit regardless of
   the flags specified, including -fPIE. Darwin never compiles in PIE
   mode, but it can *link* in PIE mode.
5) Also, PIC was not always being enabled even when PIE was. This isn't
   a supported mode at all and may have caused some fallout in builds
   with complex PIC and PIE interactions.

The result is (I hope) cleaner and clearer for readers. I've also left
comments and tests about some of the truly strage behavior that is
observed on Darwin platforms. We have no real testing of Windows
platforms and PIC, but I don't have the tools handy to figure that out.
Hopefully others can beef up our testing here.

Unfortunately, I can't test this for every platform. =/ If folks have
dependencies on these flags that aren't covered by tests, they may
break. I've audited and ensured that all the changes in behavior of the
existing tests are intentional and good. In particular I've tried to
make sure the Darwin behavior (which is more suprising than the Linux
behavior) also matches that of 'gcc' on my mac.

Chandler Carruth Fix the '-fuse-init-array' option to actually be an option.
Previously, this flag to CC1 was never exposed at the clang driver
layer, and if you happened to enable it (by being on Android or GCC 4.7
platform), you couldn't *disable* it, because there was no 'no' variant.
The whole thing was confusingly implemented.

Now, the target-specific flag processing gets the driver arg list, and
we use standard hasFlag with a default based on the GCC version and/or
Android platform. The user can still pass the 'no-' variant to forcibly
disable the flag, or pass the positive variant to clang itself to enable
the flag.

The test has also been substantially cleaned up and extended to cover
these use cases.
