- Maps to LangOptions.Exceptions
- Currently always off, should autoselect based on language.
Update CodeGen to set unwind attribute on functions definitions based
on LangOptions.Exceptions.
- Still need to set attributes appropriately on calls.

- Kill unnecessary #includes in .cpp files. This is an automatic
sweep so some things removed are actually used, but happen to be
included by a previous header. I tried to get rid of the obvious
examples and this was the easiest way to trim the #includes in one
fell swoop.
- We now return to regularly scheduled development.

- Drop {Decl.h,DeclObjC.h,IdentifierTable.h} from Expr.h
- Moved Sema::getCurMethodDecl() out of line (dependent on
ObjCMethodDecl via dyn_cast).

temporarily, I assumed GetAddrForConstantString literal was being
used consistently but it doesn't look like it is.
Factored out a CodeGenModule::getStringForStringLiteral which handles
extracting a std::string for the bytes of a StringLiteral, padded to
match the type.
Update EmitLValue to use getStringForStringLiteral, this was
previously not padding strings correctly. Good thing we only emit
strings in 4 different places!

scimark2 on Darwin.
- Added Sema support for asm-label on variables, which I forgot before.
- Update CodeGen to use GlobalDeclMap to determine if static Decls
require emission (instead of LLVM module name lookup). Important
since the Decl name and the LLVM module name can differ.

having multiple bindings from all the possible decls which
conceptually map to the same global).
- This eliminates CodeGen depending on the LLVM module for name
lookup.
- This also eliminates the need for ReplaceMapValuesWith (hurrah).
- This handles lookups for FunctionDecls correctly in the presence of
aliases, this was previously broken.
- WIP: Can still clean up & unify variable and function emission.

move getAsArrayType into ASTContext instead of being a method on type.
This is required because getAsArrayType(const AT), where AT is a typedef
for "int[10]" needs to return ArrayType(const int, 10).
Fixing this greatly simplifies getArrayDecayedType, which is a good sign.

- There is an miscompilation issue remaining due to a poor
interaction between the delayed emission of static functions and
the emission of constructors, but that already existed prior to
this change.

instead of mapping the decl to a bitcast of the global to the correct
type.
- GetAddrOf{Function,GlobalVar} introduce the bitcast on every use now.
- This solves a problem where a dangling pointer could be introduced
by the RAUW done when replacing a forward or tentative
definition. See testcase for more details.
- Fixes <rdar://problem/6108358>

- No (intended) functionality change.
- Primary purpose is to clearly separate (lazy) construction of
globals that are a forward declaration or tentative definition from
those that are the final definition.
- Lazy construction is now encapsulated in
GetAddrOf{Function,GlobalVar} while final definitions are
constructed in EmitGlobal{Function,Var}Definition.
- External interface for dealing with globals is now limited to
EmitGlobal and GetAddrOf{Function,GlobalVar}.
- Also updated helper functions dealing with statics, annotations,
and ctors to be private.

recurse on any ScopedDecl.

much closer to passing the gcc struct layout tests.
It might be possible to refactor this a bit, but I'm not sure there's
actually enough common code for that to be useful.
To get the calling convention completely correct, a bit of
platform-specific code is necessary even for x86-Linux. On x86-Linux, the
alignment of function parameters is extremely strange; as far as I can tell,
it's always 4 except for SSE vectors or structs containing SSE vectors. I'm
continuing to investigate this.

associated declaration. This is a prerequisite to handling
general union initializations; for example, an array of unions involving
pointers has to be turned into a struct because the elements can have
incompatible types.
I refactored the code a bit to make it more readable; now, the logic for
definitions is all in EmitGlobalVarInit.
The second parameter for GetAddrOfGlobalVar is now dead; I'll remove it
separately.
By itself, this patch should not cause any visible changes.

required for correctness in cases of copying a struct to itself or to
an overlapping struct (itself for cases like *a = *a, and overlapping
is possible with unions).
Hopefully, this won't end up being a perf issue; LLVM *should* be able
to optimize memmove to memcpy in a lot of cases, and for small copies
the generated code *should* be mostly comparable. (In reality, LLVM
is currently horrible at optimizing memmove, but that's a bug, not a
fundamental issue.)
gcc currently generates wrong code; that's

use its own enum for visibility types instead of using
llvm::GlobalValue::VisibilityTypes. These changes eliminate
dependencies in the AST library on LLVM's VMCore library.

as far as I can tell, and it fixes code like test/CodeGen/functions.c.
(Whatever performance effect it might have, crashing on a
construct like this isn't really acceptable; I've run into this
multiple times.)

This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it).

remaining open issues I've communicated to him:
1) self can be assigned to, and his patch didn't handle it correctly.
2) CollectObjCIvarTypes is N^2 (because each subclass reprocesses
all parent class ivars) and flattens classes. If A derives from B,
and both have an int, I'd expect to get { {i32}, i32}, not { i32, i32}.
David, please review.

lib dir and move all the libraries into it. This follows the main
llvm tree, and allows the libraries to be built in parallel. The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in. This speeds
up parallel builds, particularly incremental ones.
