Evgeniy Stepanov 93db40a147 Always_inline codegen rewrite.
Current implementation may end up emitting an undefined reference for
an "inline __attribute__((always_inline))" function by generating an
"available_externally alwaysinline" IR function for it and then failing to
inline all the calls. This happens when a call to such function is in dead
code. As the inliner is an SCC pass, it does not process dead code.

Libc++ relies on the compiler never emitting such undefined reference.

With this patch, we emit a pair of
1. internal alwaysinline definition (called F.alwaysinline)
2a. A stub F() { musttail call F.alwaysinline }
  -- or, depending on the linkage --
2b. A declaration of F.

The frontend ensures that F.inlinefunction is only used for direct
calls, and the stub is used for everything else (taking the address of
the function, really). Declaration (2b) is emitted in the case when
"inline" is meant for inlining only (like __gnu_inline__ and some
other cases).

This approach, among other nice properties, ensures that alwaysinline
functions are always internal, making it impossible for a direct call
to such function to produce an undefined symbol reference.

This patch is based on ideas by Chandler Carruth and Richard Smith.

David Majnemer 69c3ddc44a [MS ABI] Select an inheritance model in template arguments
We used to only select an inheritance model if the pointer to member was

N.B.  This bug was exposed by making member pointers report true for
isIncompleteType but has been latent since the member pointer scheme's
inception.

Devin Coughlin 0123af994e [analyzer] Add -analyzer-config option for function size the inliner considers as large
Add an option (-analyzer-config min-blocks-for-inline-large=14) to control the function
size the inliner considers as large, in relation to "max-times-inline-large". The option
defaults to the original hard coded behaviour, which I believe should be adjustable with
the other inlining settings.

The analyzer-config test has been modified so that the analyzer will reach the
getMinBlocksForInlineLarge() method and store the result in the ConfigTable, to ensure it
is dumped by the debug checker.

Vedant Kumar db609471ce [CodeGen] Teach SimplifyPersonality about the updated LandingPadInst
When uses of personality functions were moved from LandingPadInst to
Function, we forgot to update SimplifyPersonality(). This patch corrects
that.

Note: SimplifyPersonality() is an optimization which replaces
personality functions with the default C++ personality when possible.
Without this update, some ObjC++ projects fail to link against C++
libraries (seeing as the exception ABI had effectively changed).

Aaron Ballman b85be665b0 Fixed HasDeclarationMatcher to properly convert all types into decls where possible. Added objcObjectPointerType(), objcInterfaceDecl(), templateTypeParmType(), injectedClassNameType(), and unresolvedUsingTypenameDecl(). Updated documentation for pointerType() to call out that it does not match ObjCObjectPointerType types. Changed pointsTo() to handle ObjCObjectPointerType as well as PointerType.
While this may seem like a lot of unrelated changes, they all relate back to fixing HasDeclarationMatcher.

This now allows us to write a matcher like:

varDecl(hasType(namedDecl(hasName("Foo"))))

that matches code using typedefs, objc interfaces, template type parameters, injected class names, or unresolved using typenames.

Alexey Bataev 2377fe95c6 [OPENMP] Outlined function for parallel and other regions with list of captured variables.
Currently all variables used in OpenMP regions are captured into a record and passed to outlined functions in this record. It may result in some poor performance because of too complex analysis later in optimization passes. Patch makes to emit outlined functions for parallel-based regions with a list of captured variables. It reduces code for 2*n GEPs, stores and loads at least.
Codegen for task-based regions remains unchanged because runtime requires that all captured variables are passed in captured record.

Hopefully I got it right this time: lifetime of initializer list ends

John McCall 7f416cc426 Compute and preserve alignment more faithfully in IR-generation.
Introduce an Address type to bundle a pointer value with an
alignment.  Introduce APIs on CGBuilderTy to work with Address
values.  Change core APIs on CGF/CGM to traffic in Address where
appropriate.  Require alignments to be non-zero.  Update a ton
of code to compute and propagate alignment information.

As part of this, I've promoted CGBuiltin's EmitPointerWithAlignment
helper function to CGF and made use of it in a number of places in
the expression emitter.

The end result is that we should now be significantly more correct
when performing operations on objects that are locally known to
be under-aligned.  Since alignment is not reliably tracked in the
type system, there are inherent limits to this, but at least we
are no longer confused by standard operations like derived-to-base
conversions and array-to-pointer decay.  I've also fixed a large
number of bugs where we were applying the complete-object alignment
to a pointer instead of the non-virtual alignment, although most of
these were hidden by the very conservative approach we took with
member alignment.

Also, because IRGen now reliably asserts on zero alignments, we
should no longer be subject to an absurd but frustrating recurring
bug where an incomplete type would report a zero alignment and then
we'd naively do a alignmentAtOffset on it and emit code using an
alignment equal to the largest power-of-two factor of the offset.

We should also now be emitting much more aggressive alignment
attributes in the presence of over-alignment.  In particular,
field access now uses alignmentAtOffset instead of min.

Several times in this patch, I had to change the existing
code-generation pattern in order to more effectively use
the Address APIs.  For the most part, this seems to be a strict
improvement, like doing pointer arithmetic with GEPs instead of
ptrtoint.  That said, I've tried very hard to not change semantics,
but it is likely that I've failed in a few places, for which I
apologize.

ABIArgInfo now always carries the assumed alignment of indirect and
indirect byval arguments.  In order to cut down on what was already
a dauntingly large patch, I changed the code to never set align
attributes in the IR on non-byval indirect arguments.  That is,
we still generate code which assumes that indirect arguments have
the given alignment, but we don't express this information to the
backend except where it's semantically required (i.e. on byvals).
This is likely a minor regression for those targets that did provide
this information, but it'll be trivial to add it back in a later
patch.

I partially punted on applying this work to CGBuiltin.  Please
do not add more uses of the CreateDefaultAligned{Load,Store}
APIs; they will be going away eventually.

Hal Finkel 0e2b975eb6 Don't crash on a self-alias declaration
We were crashing in CodeGen given input like this:

  int self_alias(void) __attribute__((weak, alias("self_alias")));

such a self-alias is invalid, but instead of diagnosing the situation, we'd
proceed to produce IR for both the function declaration and the alias. Because
we already had a function named 'self_alias', the alias could not be named the
same thing, and so LLVM would pick a different name ('self_alias1' for example)
for that value. When we later called CodeGenModule::checkAliases, we'd look up
the IR value corresponding to the alias name, find the function declaration
instead, and then assert in a cast to llvm::GlobalAlias. The easiest way to prevent
this is simply to avoid creating the wrongly-named alias value in the first
place and issue the diagnostic there (instead of in checkAliases). We detect a
related cycle case in CodeGenModule::EmitAliasDefinition already, so this just
adds a second such check.

Even though the other test cases for this 'alias definition is part of a cycle'
diagnostic are in test/Sema/attr-alias-elf.c, I've added a separate regression
test for this case. This is because I can't add this check to
test/Sema/attr-alias-elf.c without disturbing the other test cases in that
file. In order to avoid construction of the bad IR values, this diagnostic
is emitted from within CodeGenModule::EmitAliasDefinition (and the relevant
declaration is not added to the Aliases vector). The other cycle checks are
done within the CodeGenModule::checkAliases function based on the Aliases
vector, called from CodeGenModule::Release.  However, if there have been errors
earlier, HandleTranslationUnit does not call Release, and so checkAliases is
never called, and so none of the other diagnostics would be produced.

Fixes PR23509.

  even if we could provide an answer to
    __builtin_object_size(&foo, N);
  We now provide the same answer for both of the above examples in all
  cases.

- For type=1|3, we now support subobjects with unknown bases, as long
  as the designator is valid.

Thanks to Richard Smith for the review + design planning.

Ed Schouten e8eab68b55 Put ext_implicit_lib_function_decl in ImplicitFunctionDeclare.
If we build with -Werror=implicit-function-declaration, only implicit
function declarations of non-library functions throw compiler errors.
For library functions, we only produce a warning. There is no way to
promote both of these cases to an error without promoting other
warnings.

It makes little sense to introduce an additional compiler flag just to
control this specific warning. In my opinion it should just be part of
the same group.

Summary:
Dtor sanitization handled amidst other dtor cleanups,
between cleaning bases and fields. Sanitizer call pushed onto
stack of cleanup operations.

Reviewers: eugenis, kcc

Differential Revision: http://reviews.llvm.org/D12022

Refactoring dtor sanitizing emission order.

- Support multiple inheritance by poisoning after
 member destructors are invoked, and before base
 class destructors are invoked.
- Poison for virtual destructor and virtual bases.
- Repress dtor aliasing when sanitizing in dtor.
- CFE test for dtor aliasing, and repression of aliasing in dtor
 code generation.
- Poison members on field-by-field basis, with collective poisoning
 of trivial members when possible.
- Check msan flags and existence of fields, before dtor sanitizing,
 and when determining if aliasing is allowed.
- Testing sanitizing bit fields.

Oliver Stannard dc2854c2f1 [ARM] Allow passing/returning of __fp16 arguments
The ACLE (ARM C Language Extensions) 2.0 allows the __fp16 type to be
used as a functon argument or return type (ACLE 1.1 did not).

The current public release of the AAPCS (2.09) states that __fp16 values
should be converted to single-precision before being passed or returned,
but AAPCS 2.10 (to be released shortly) changes this, so that they are
passed in the least-significant 16 bits of either a GPR (for base AAPCS)
or a single-precision register (for AAPCS-VFP). This does not change how
arguments are passed if they get passed on the stack.

This patch brings clang up to compliance with the latest versions of
both of these specs.

We can now set the __ARM_FP16_ARGS ACLE predefine, and we have always
been able to set the __ARM_FP16_FORMAT_IEEE predefine (we do not support
the alternative format).

Alexey Bataev 6b8046addf [OPENMP 4.1] Parsing/sema analysis for extended format of 'if' clause.
OpenMP 4.1 added special 'directive-name-modifier' to the 'if' clause.
Format of 'if' clause is as follows:
```
if([ directive-name-modifier :] scalar-logical-expression)
```

The restriction rules are also changed.
1. If any 'if' clause on the directive includes a 'directive-name-modifier' then all 'if' clauses on the directive must include a 'directive-name-modifier'.
2. At most one 'if' clause without a 'directive-name-modifier' can appear on the directive.
3. At most one 'if' clause with some particular 'directive-name-modifier' can appear on the directive.

'directive-name-modifier' is important for combined directives and allows to separate conditions in 'if' clause for simple sub-directives in combined directive. This 'directive-name-modifier' identifies the sub-directive to which this 'if' clause must be applied.

Original commit message:

[modules] Rework serialized DeclContext lookup table management. Instead of
walking the loaded ModuleFiles looking for lookup tables for the context, store
them all in one place, and merge them together if we find we have too many
(currently, more than 4). If we do merge, include the merged form in our
serialized lookup table, so that downstream readers never need to look at our
imports' tables.

This gives a huge performance improvement to builds with very large numbers of
modules (in some cases, more than a 2x speedup was observed).

Rafael Espindola c53c5b13be Stop hardcoding GCC paths in crt/ld.so lookup.
This patch refactors the code to use the GCC installation detector
(modified so that it works in Solaris), and uses
ToolChain::GetFilePath everywhere once it works.

David Majnemer 0035052729 [MS ABI] Correctly mangle classes without names for linkage purposes
A class without a name for linkage purposes gets a name along the lines
of <unnamed-type-foo> where foo is either the name of a declarator which
defined it (like a variable or field) or a
typedef-name (like a typedef or alias-declaration).

We handled the declarator case correctly but it would fall down during
template instantiation if the declarator didn't share the tag's type.
We failed to handle the typedef-name case at all.

Instead, keep track of the association between the two and keep it up to
date in the face of template instantiation.

Yaron Keren 43e184ee0c Make test resistant to false matches of numbered (unnamed) labels inside other numbers.
In release builds labels are numbers. Matching just the number may result
in false matches where the label is contained in other numbers, such as
14 inside [114 x i8]. A stricter match requiring start of line or > character
before the label avoids these false matches.

This replaces the filtered generic iterator with a type-specfic one based

Devin Coughlin 35d5dd2986 [analyzer] When memcpy'ing into a fixed-size array, do not invalidate entire region.
Change the analyzer's modeling of memcpy to be more precise when copying into fixed-size
array fields. With this change, instead of invalidating the entire containing region the
analyzer now invalidates only offsets for the array itself when it can show that the
memcpy stays within the bounds of the array.

This addresses false positive memory leak warnings of the kind reported by
krzysztof in https://llvm.org/bugs/show_bug.cgi?id=22954

Hans Wennborg 6eaa8323a8 Allow TLS vars in dllimport/export functions; only inline dllimport functions when safe (PR24593)
This patch does two things:

1) Don't error about dllimport/export on thread-local static local variables.
   We put those attributes on static locals in dllimport/export functions
   implicitly in case the function gets inlined. Now, for TLS variables this
   is a problem because we can't import such variables, but it's a benign
   problem becase:

2) Make sure we never inline a dllimport function TLS static locals. In fact,
   never inline a dllimport function that references a non-imported function
   or variable (because these are not defined in the importing library). This
   seems to match MSVC's behaviour.
