non-template classes when computing the key function.

- The vtable for an instantiation of a class template has weak
linkage.
We could probably use available_externally linkage for vtables of
classes instantiated by explicit instantiation declarations (extern
templates), but GCC doesn't do this and I'm not 100% that the ABI
permits it.

Switch the initialization required by return statements over to the
...
new InitializationSequence. This fixes some bugs (e.g., PR5808),
changed some diagnostics, and caused more churn than expected. What's
new:
- InitializationSequence now has a "C conversion sequence" category
and step kind, which falls back to
- Changed the diagnostics for returns to always have the result type
of the function first and the type of the expression second.
CheckSingleAssignmentConstraints to peform checking in C.
- Improved ASTs for initialization of return values. The ASTs now
capture all of the temporaries we need to create, but
intentionally do not bind the tempoary that is actually returned,
so that it won't get destroyed twice.
- Make sure to perform an (elidable!) copy of the class object that
is returned from a class.
- Fix copy elision in CodeGen to properly see through the
subexpressions that occur with elidable copies.
- Give "new" its own entity kind; as with return values and thrown
objects, we don't bind the expression so we don't call a
destructor for it.
Note that, with this patch, I've broken returning move-only types in
C++0x. We'll fix it later, when we tackle NRVO.

Make copy assignment operator synthesis not explode for classes with complex
...
or non-record aggregate members.
It might be worth spending some time to optimize this code (and the parallel
code for copy constructors) to memcpy in larger chunks, rather than copying
one member at a time. Not sure exactly how beneficial that would be, but
it seems like could help for large classes with, for example, a vtable pointer
forcing the generation of a copy constructor.

Use the more general Evaluate infrastructure for folding constant DeclRefs
...
instead of checking explicitly for an EnumConstantDecl. This folds references

1. Slightly smaller emitted code from emitting a constant instead of a load,

2. Some code forgets to define static constant member variables; emitting a
load instead of the value in that case leads to a link error. (Such programs
are technically not well-formed, but in practice build with g++.)

All statements that involve conditions can now hold on to a separate

Also, since this change reworks the Action interface for
if/while/switch/for, use FullExprArg for the full expressions in those
expressions, to ensure that we're emitting

Introduce cleanup scopes for "if" statements in two places:
...
- Outside the "if", to ensure that we destroy the condition variable
at the end of the "if" statement rather than at the end of the
block containing the "if" statement.
- Inside the "then" and "else" branches, so that we emit then- or
else-local cleanups at the end of the corresponding block when the
block is not a compound statement.
To make adding these new cleanup scopes easier (and since
switch/do/while will all need the same treatment), added the
CleanupScope RAII object to introduce a new cleanup scope and make
sure it gets cleaned up.

may not co-exist with the new changes.
Doug, please look at a FIXME in PCHWriter.cpp/PCHReader.cpp.

need be considered for in a few Indexer/PCH test cases.

First part of changes to eliminate problems with cv-qualifiers and
...
sugared types. The basic problem is that our qualifier accessors
(getQualifiers, getCVRQualifiers, isConstQualified, etc.) only look at
the current QualType and not at any qualifiers that come from sugared
types, meaning that we won't see these qualifiers through, e.g.,
typedefs:
typedef const int CInt;
typedef CInt Self;
Self.isConstQualified() currently returns false!
Various bugs (e.g., PR5383) have cropped up all over the front end due
to such problems. I'm addressing this problem by splitting each
qualifier accessor into two versions:
- the "local" version only returns qualifiers on this particular
QualType instance
- the "normal" version that will eventually combine qualifiers from this
QualType instance with the qualifiers on the canonical type to
produce the full set of qualifiers.
This commit adds the local versions and switches a few callers from
the "normal" version (e.g., isConstQualified) over to the "local"
version (e.g., isLocalConstQualified) when that is the right thing to
do, e.g., because we're printing or serializing the qualifiers. Also,
switch a bunch of
Context.getCanonicalType(T1).getUnqualifiedType() == Context.getCanonicalType(T2).getQualifiedType()
expressions over to
Context.hasSameUnqualifiedType(T1, T2)

Unify the codepaths used to verify base and member initializers for explicitly

1. Less code.
2. Explicit and implicit constructors get the same diagnostics.

constructors. This allows handing some cases that previously weren't handled
correctly in IRGen without any additional code. Specifically, implicit default
constructors containing calls to constructors with default arguments are now
handled correctly.

Eliminate QualifiedDeclRefExpr, which captured the notion of a
...
qualified reference to a declaration that is not a non-static data
member or non-static member function, e.g.,
namespace N { int i; }
int j = N::i;
Instead, extend DeclRefExpr to optionally store the qualifier. Most
clients won't see or care about the difference (since
QualifierDeclRefExpr inherited DeclRefExpr). However, this reduces the
number of top-level expression types that clients need to cope with,
brings the implementation of DeclRefExpr into line with MemberExpr,
and simplifies and unifies our handling of declaration references.
Extended DeclRefExpr to (optionally) store explicitly-specified
template arguments. This occurs when naming a declaration via a
template-id (which will be stored in a TemplateIdRefExpr) that,
following template argument deduction and (possibly) overload
resolution, is replaced with a DeclRefExpr that refers to a template
specialization but maintains the template arguments as written.

When building types from declarators, instead of building two types (one for
...
the DeclaratorInfo, one for semantic analysis), just build a single type whose
canonical type will reflect the semantic analysis (assuming the type is
well-formed, of course).
To make that work, make a few changes to the type system:
* allow the nominal pointee type of a reference type to be a (possibly sugared)
reference type. Also, preserve the original spelling of the reference type.
Both of these can be ignored on canonical reference types.
* Remove ObjCProtocolListType and preserve the associated source information on
the various ObjC TypeLocs. Preserve the spelling of protocol lists except in
the canonical form.
* Preserve some level of source type structure on parameter types, but
canonicalize on the canonical function type. This is still a WIP.
Drops code size, makes strides towards accurate source location representation,
slight (~1.7%) progression on Cocoa.h because of complexity drop.

1. CGF now has fewer bytes of state (one pointer instead of a vector).
2. The generated code is determinstic, instead of getting labels in

3. Clang now emits one 'indirect goto switch' for each function, instead
of one for each indirect goto. This fixes an M*N = N^2 IR size issue
when there are lots of address-taken labels and lots of indirect gotos.
4. This also makes the default cause do something useful, reducing the

Fix subtle bug in generating LLVM function declarations for builtin functions.
...
The decl wasn't being passed down, which meant that function attributes were not
being set correctly. This is particularly important for ARM, since it wants to
override the calling convention. Instead we would emit the builtin with the
wrong calling convention, and instcombine would come along and merrily shred all
the calls to it. :)

When a member reference expression includes a qualifier on the member
...
name, e.g.,
x->Base::f()
retain the qualifier (and its source range information) in a new
subclass of MemberExpr called CXXQualifiedMemberExpr. Provide
construction, transformation, profiling, printing, etc., for this new
expression type.
When a virtual function is called via a qualified name, don't emit a
virtual call. Instead, call that function directly. Mike, could you
add a CodeGen test for this, too?

Initial patch to support definitions of id and Class from headers in Objective-C code.
...
This currently breaks test/SemaObjC/id-isa-ref.m and issues some spurious warnings when you attempt to assign a struct objc_class* value to a Class variable. The test case probably should fail as it's written, because without the definition of Class the compiler should not assume struct objc_class* is a valid receiver type, but it's left broken because it would be nice if we could get that passing too for the special case of isa.

Fix for PR4721: adjust CodeGen and ASTContext so that we have a
...
consistent model for handling size expressions for VLAs.
The model is essentially as follows: VLA types own their associated
expression. In some cases, we need to create multiple VLA types to
represent a given VLA (for canonical types, or qualifiers on array types,
or type merging). If we need to create multiple types based off of
the same VLA declaration, we use the new refcounting functionality so they can
all own the expression. The VLASizeMap in CodeGenFunction then uses the size
expression to identify the group of VLA types based off of the same original
declaration.
I'm not particularly attached to the VLA types owning the expression,
but we're stuck with at least until someone comes up with a way
to walk the VLA expressions for a declaration.
I did the parallel fix in ASTContext for DependentSizedArrayType, but I
haven't really looked closely at it, so there might still be issues
there.
I'll clean up the code duplication in ASTContext in a followup commit.

Hey, I've decided I want a change to FileCheck, I need to ensure that
the group is together, nothing in between. Can we change it to check
the match line is from the line immediately following the last matched
line, if the source for the matched line is immediately after the
source for the previously matched line?
// CHECK: 1
// CHECK: 2
// CHECK: 3
// CHECK: 4
// CHECK: 5
// CHECK: 6
would require 1 2 and 3 to be continuous in the output, and 4 5 and 6
to be continuous.

Add member template 'Type::getAs<T>', which converts a Type* to a respective T*.
...
This method is intended to eventually replace the individual
Type::getAsXXXType<> methods.
The motivation behind this change is twofold:
1) Reduce redundant implementations of Type::getAsXXXType() methods. Most of
them are basically copy-and-paste.
2) By centralizing the implementation of the getAs<Type> logic we can more
smoothly move over to Doug Gregor's proposed canonical type smart pointer
scheme.
Along with this patch:
a) Removed 'Type::getAsPointerType()'; now clients use getAs<PointerType>.
b) Removed 'Type::getAsBlockPointerTypE()'; now clients use getAs<BlockPointerType>.

This patch includes a conceptually simple, but very intrusive/pervasive change.
...
The idea is to segregate Objective-C "object" pointers from general C pointers (utilizing the recently added ObjCObjectPointerType). The fun starts in Sema::GetTypeForDeclarator(), where "SomeInterface *" is now represented by a single AST node (rather than a PointerType whose Pointee is an ObjCInterfaceType). Since a significant amount of code assumed ObjC object pointers where based on C pointers/structs, this patch is very tedious. It should also explain why it is hard to accomplish this in smaller, self-contained patches.
This patch does most of the "heavy lifting" related to moving from PointerType->ObjCObjectPointerType. It doesn't include all potential "cleanups". The good news is additional cleanups can be done later (some are noted in the code). This patch is so large that I didn't want to include any changes that are purely aesthetic.
By making the ObjC types truly built-in, they are much easier to work with (and require fewer "hacks"). For example, there is no need for ASTContext::isObjCIdStructType() or ASTContext::isObjCClassStructType()! We believe this change (and the follow-up cleanups) will pay dividends over time.
Given the amount of code change, I do expect some fallout from this change (though it does pass all of the clang tests). If you notice any problems, please let us know asap! Thanks.

De-ASTContext-ify DeclContext.
...
Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating".

Remove the ASTContext parameter from the attribute-related methods of Decl.

This commit touches a lot of files since call sites for these methods are everywhere.
I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it.

Key decisions about 'bool' vs '_Bool' to be based on a new flag in langoptions.
...
This is simple enough, but then I thought it would be nice to make PrintingPolicy
get a LangOptions so that various things can key off "bool" and "C++" independently.
This spiraled out of control. There are many fixme's, but I think things are slightly
better than they were before.
One thing that can be improved: CFG should probably have an ASTContext pointer in it,
which would simplify its clients.

Improve code generation for function template specializations:
...
- Track implicit instantiations vs. the not-yet-supported explicit
specializations
- Give implicit instantiations of function templates (and member
functions of class templates) linkonce_odr linkage.
- Improve name mangling for function template specializations,
including the template arguments of the instantiation and the return
type of the function.
Note that our name-mangling is improved, but not correct: we still
don't mangle substitutions, although the manglings we produce can be
demangled.

Fixup debug information for the location information for __block

A typical utterance would be:

%0 = load i8** %forwarding ; <i8*> [#uses=1]

%x = getelementptr %0* %1, i32 0, i32 4 ; <i32*> [#uses=1]
%2 = bitcast i32* %x to { }* ; <{ }*> [#uses=1]
call void @llvm.dbg.declare({ }* %2, { }* bitcast (%llvm.dbg.variable.type* @llvm.dbg.variable to { }*))

initial support for ObjC exceptions with the GNU runtime:

"This patch is a first pass at adding support for exceptions for the GNU runtime. There are a few limitations at present:
- @synchronized() is not yet supported at all. gcc currently emits calls to runtime library functions that don't exist for this directive.
- Only id @catch statements are currently working. This is enough for NS_DURING and friends, but I need to spend more time reading the output from gcc -S to work out how it finds the class pointer to make arbitrary class type catch statements work.
- I've tested it with a few common cases[1] and the clang test suite (which doesn't test exceptions for the GNU runtime, but shows I haven't broken anything else), but there are probably a lot of cases I've missed."

Fix the field count in interface record layout (it was incorrectly

compensating for super classes). This was making the reported class
sizes for empty classes very, very wrong.
- Also, we now report the size info for an empty class like gcc (as
the offset of the start, not as 0, 0).

field at end of struct, for example).

"Fix" a problem with debug info in the presence of always_inline
...
function calls. For a program like this:
#include <stdio.h>
static __inline__ __attribute__((always_inline))
int bar(int x) { return 4; }
int main() {
int X = bar(4);
printf("%d\n", X);
}
clang was not outputing any debug info for the body of main(). This is
because the backend is getting confused by the region_start/end that clang
is emitting for block scopes. For now, just disable these (matching llvm-gcc),
this stuff is in progress of rework anyway.

Don't allow clients to traverse into superclass synthesized properties
...
via CollectObjCIvars.
- In places where we need them, we should have the implementation and
access the properties through it.
This is a fairly substantial functionality change:
1. @encode no longer encodes synthesized ivars, ever.
2. The ivar layout bitmap no longer encodes information for
synthesized ivars in superclasses. Well, actually I had already
broken that, but it is intentional now.
We are now differing substantially from llvm-gcc and gcc
here. However, in my opinion this fundamentally *must* work if
non-fragile classes are to work. Without this change, the result of
@encode and the ivar layout depend on the order that the
implementation is seen in a file (if it is in the same file with its
superclass). Since both scenarios should work the same, our behavior
is now consistent with gcc behavior as if an implementation is never
seen following an implementation of its superclass.
Note that #2 is only a functionality change when (A) an
implementation appears in the same translation unit with the
implementation of its superclass, and (B) the superclass has
synthesized ivars. My belief is that this situation does not occur in
practice.
I am not yet sure of the role/semantics of @encode when synthesized
ivars are present... it's use is fairly unsound in a non-fragile world.

Rework the shadow struct that is layed out for Objective-C classes.
- Superclasses are now always laid out in their shadow structure at
the first field.
- Prior to this, the entire class heirarchy was flattened into a
single structure which meant that alignment, padding, and bitfields
were incorrect (the ASTRecordLayout was correct however, which
meant our debug info didn't coincide with ivar offsets, for
example).
- This is still very suboptimal (for example, ivar are looked up
recursively, but I believe the ivar layout itself is now at least
close to correct.

Don't convert interface types (to structs) as part of CodeGenTypes.
...
- This has pros and cons, but for now the pros seem to significantly
outway the con.
The con is that we will always need to cast in the runtime
implementation to a struct type, if we wish to access an interface
directly.
The pros are:
- Avoid the cost of generating types which are used. Most
manipulation of Objective-C objects is done through messages, and
only the implementation of a class will directly access
memory. Previously, we would convert the type even if it only
appear as a function parameter, for example.
- We don't need to worry about incomplete types, and
UpdateCompletedType for interfaces is gone.
- It becomes easier to narrow the interface to the shadow struct for
Objective-C interfaces (so it can be eliminated).
Currently the runtimes still use the CodeGenTypes machinery to
generate the LLVM structure they need via ConvertTagDecl, but this can
eventually be replaced.

Rework the shadow struct that is layed out for Objective-C classes.
...
- Superclasses are now always laid out their shadow structure at the
first field.
- Prior to this, the entire class heirarchy was flattened into a
single structure which meant that alignment, padding, and bitfields
weren't packed correctly (the ASTRecordLayout was correct however,
which meant our debug info didn't coincide with ivar offsets, for
example).
- This is still very suboptimal, but I believe the ivar layout itself
is now at least close to correct.

Refactor how attributes are set on values.
...
- Pull out SetCommonAttributes, which handles the things common to
aliases, methods, functions, and variables.
- Pull out SetLLVMFunctionAttributesForDefinition, which handles the
LLVM attributes which we only want to apply to a definition (like
noinline and alwaysinline).
- Kill SetGVDeclarationAttributes (inlined into SetFunctionAttributes
and specialized).
- Kill SetFunctionAttributesForDefinition (inlined into sole caller).
- Inline SetGVDefinitionAttributes into SetMethodAttributes and
specialize.
- Rename SetGVDefinitionAttributes to SetFunctionDefinitionAttributes.

have made a mistake.

- Exposed quite a few Sema issues and a CodeGen crash.
- See FIXMEs in test case, and in SemaDecl.cpp (PR3983).
I'm skeptical that __private_extern__ should actually be a storage
class value. I think that __private_extern__ basically amounts to
extern A __attribute__((visibility("hidden")))
and would be better off handled (a) as that, or (b) with an extra bit
in the VarDecl.

Make debug info work when using -save-temps.
...
- This is pretty ugly, but the most obvious solution. Chime in if you
have a nicer one.
- The problem is that with -save-temps, clang-cc has no idea what the
name of the original input file is. However, the user expects to be
able to set breakpoints based on the input file name.
- We support this by providing a new option -main-file-name (similar
to -dumpbase used by gcc) which allows the driver to pass in the
original file name.
- <rdar://problem/6753383> building with clang using --save-temps
gets the compile unit name from the .i file...

- Changed method names to match gcc (categories names still aren't

(I suspect this can still be trimmed).
- Don't use asm-prefix extension for _objc_empty_{cache,vtable} (not
needed).
- Hide EH type class info with -fvisibility=hidden
- Change setGlobal[Option]Visibility to not change the visibility of
functions with internal linkage.
