2bd09db07f ADT: correctly report isMSVCEnvironment for windows itanium
The itanium environment on Windows uses MSVC and is a MSVC environment.  Report
this correctly.

dada992be7 Use size_type for operator[].
This matches std::vector and is more efficient as it avoids
truncations.

With this the text segment of opt goes from 19705442 bytes

d9078385de Ensure function_refs are copyable even from non-const references
A subtle bug was found where attempting to copy a non-const function_ref
lvalue would actually invoke the generic forwarding constructor (as it
was a closer match - being T& rather than the const T& of the implicit
copy constructor). In the particular case this lead to a dangling
function_ref member (since it had referenced the function_ref passed by
value to its ctor, rather than the outer function_ref that was still
alive)

SFINAE the converting constructor to not be considered if the copy
constructor is available and demonstrate that this causes the copy to
refer to the original functor, not to the function_ref it was copied
from. (without the code change, the test would fail as Y would be
referencing X and Y() would see the result of the mutation to X, ie: 2)

One of many steps to generalize subprogram emission to both the DWO and
non-DWO sections (to emit -gmlt-like data under fission). Once the
functions are pushed down into DwarfCompileUnit some of the data
structures will be pushed at least into DwarfFile so that they can be
unique per-file, allowing emission to both files independently.

771ac70aed Add an emplace(...) method to llvm::Optional<T>.
This can be used for in-place initialization of non-moveable types.
For compilers that don't support variadic templates, only up to four
arguments are supported. We can always add more, of course, but this
should be good enough until we move to a later MSVC that has full
support for variadic templates.

151f8cef74 APInt: Make self-move-assignment a no-op to fix stage3 clang-cl
It's not clear what the semantics of a self-move should be.  The
consensus appears to be that a self-move should leave the object in a
moved-from state, which is what our existing move assignment operator
does.

However, the MSVC 2013 STL will perform self-moves in some cases.  In
particular, when doing a std::stable_sort of an already sorted APSInt
vector of an appropriate size, one of the merge steps will self-move
half of the elements.

We don't notice this when building with MSVC, because MSVC will not
synthesize the move assignment operator for APSInt.  Presumably MSVC
does this because APInt, the base class, has user-declared special
members that implicitly delete move special members.  Instead, MSVC
selects the copy-assign operator, which defends against self-assignment.
Clang, on the other hand, selects the move-assign operator, and we get
garbage APInts.

8e704b16f1 [ADT] Add a remarkbly useful little helper routine to ArrayRef for
checking whether the ArrayRef is equal to an explicit list of arguments.

This is particularly easy to implement even without variadic templates
because ArrayRef happens to be homogeneously typed. As a consequence we
can use a "clever" wrapper type and default arguments to capture in
a single method many arguments as well as *how many* arguments the user
specified.

9231148e69 AArch64: remove arm64 triple enumerator.
Having both Triple::arm64 and Triple::aarch64 is extremely confusing, and
invites bugs where only one is checked. In reality, the only legitimate
difference between the two (arm64 usually means iOS) is also present in the OS
part of the triple and that's what should be checked.

We still parse the "arm64" triple, just canonicalise it to Triple::aarch64, so
there aren't any LLVM-side test changes.

d9ebc5991b ADT: Fix MapVector::erase()
Actually update the changed indexes in the map portion of `MapVector`
when erasing from the middle.  Add a unit test that checks for this.

Note that `MapVector::erase()` is a linear time operation (it was and
still is).  I'll commit a new method in a moment called
`MapVector::remove_if()` that deletes multiple entries in linear time,
which should be slightly less painful.

c8a1169c93 IR: Add COMDATs to the IR
This new IR facility allows us to represent the object-file semantic of
a COMDAT group.

COMDATs allow us to tie together sections and make the inclusion of one
dependent on another. This is required to implement features like MS
ABI VFTables and optimizing away certain kinds of initialization in C++.

This functionality is only representable in COFF and ELF, Mach-O has no
similar mechanism.

212e2b9c8d Reverting size_type for the containers from size_type to unsigned.
Various places in LLVM assume that container size and count are unsigned
and do not use the container size_type. Therefore they break compilation
(or possibly executation) for LP64 systems where size_t is 64 bit while
unsigned is still 32 bit.

If we'll ever that many items in the container size_type could be made
size_t for a specific containers after reviweing its other uses.

ed4e8a839f The count() function for STL datatypes returns unsigned, even where it's
only 1/0 result like std::set. Some of the LLVM ADT already return unsigned
count(), while others still return bool count().

In continuation to r197879, this patch modifies DenseMap, DenseSet, 
ScopedHashTable, ValueMap:: count() to return size_type instead of bool,
1 instead of true and 0 instead of false.

size_type is typedef-ed locally within each class to size_t.

78b4fd3a4b SmallVector: support resize(N) with move-only types
Unfortunately there's no way to elegantly do this with pre-canned
algorithms. Using a generating iterator doesn't work because you default
construct for each element, then move construct into the actual slot
(bad for copy but non-movable types, and a little unneeded overhead even
in the move-only case), so just write it out manually.

This solution isn't exception safe (if one of the element's ctors calls
we don't fall back, destroy the constructed elements, and throw on -
which std::uninitialized_fill does do) but SmallVector (and LLVM) isn't
exception safe anyway.

e570687bd8 Ensure SmallVector::insert doesn't overwrite the last element in the range with the already-moved-from value
This would cause the last element in a range to be in a moved-from state
after an insert at a non-end position, losing that value entirely in the
process.

Side note: move_backward is subtle. It copies [A, B) to C-1 and down.
(the fact that it decrements both the second and third iterators before
the first movement is the subtle part... kind of surprising, anyway)

ee8af3e2a0 Recommit r208506: DebugInfo: Include lexical scopes in inlined subroutines.
This was reverted in r208642 due to regressions surrounding file changes
within lexical scopes causing inlining information to be lost.

The issue was in LexicalScopes::getOrCreateInlinedScope, where I was
previously testing "isLexicalBlock" which is false for
"DILexicalBlockFile" (a scope used to represent changes in the current
file name) and assuming it was then a function (breaking out of the
inlined scope path and reaching for the parent non-inlined scopes). By
inverting the condition and testing for "isSubprogram" the correct
behavior is attained.

(also found some weirdness in Clang, see r208742 when reducing this test
case - the resulting test case doesn't apply with the Clang fix, but
I've added a more realistic test case to inline-scopes.ll which does
reproduce the issue and demonstrate the fix)

When we were moving from a larger vector to a smaller one but didn't
need to re-allocate, we would move-assign over uninitialized memory in
the target, then move-construct that same data again.

beee61d3e6 [ADT] Add a generic iterator utility for adapting iterators much like
Boost's iterator_adaptor, and a specific adaptor which iterates over
pointees when wrapped around an iterator over pointers.

This is the result of a long discussion on IRC with Duncan Smith, Dave
Blaikie, Richard Smith, and myself. Essentially, I could use some subset
of the iterator facade facilities often used from Boost, and everyone
seemed interested in having the functionality in a reasonably generic
form. I've tried to strike a balance between the pragmatism and the
established Boost design. The primary differences are:

1) Delegating to the standard iterator interface names rather than
   special names that then make up a second iterator-like API.
2) Using the name 'pointee_iterator' which seems more clear than
   'indirect_iterator'. The whole business of calling the '*p' operation
   'pointer indirection' in the standard is ... quite confusing. And
   'dereference' is no better of a term for moving from a pointer to
   a reference.

Hoping Duncan, and others continue to provide comments on this until
we've got a nice, minimal abstraction.

2ea701e67a Canonicalise Windows target triple spellings
Construct a uniform Windows target triple nomenclature which is congruent to the
Linux counterpart.  The old triples are normalised to the new canonical form.
This cleans up the long-standing issue of odd naming for various Windows
environments.

There are four different environments on Windows:

MSVC: The MS ABI, MSVCRT environment as defined by Microsoft
GNU: The MinGW32/MinGW32-W64 environment which uses MSVCRT and auxiliary libraries
Itanium: The MSVCRT environment + libc++ built with Itanium ABI
Cygnus: The Cygwin environment which uses custom libraries for everything

The following spellings are now written as:

4eb048a6f1 Support: split object format out of environment
This is a preliminary setup change to support a renaming of Windows target
triples.  Split the object file format information out of the environment into a
separate entity.  Unfortunately, file format was previously treated as an
environment with an unknown OS.  This is most obvious in the ARM subtarget where
the handling for macho on an arbitrary platform switches to AAPCS rather than
APCS (as per Apple's needs).

7225e27b4c [Modules] Move ValueMap to the IR library. While this class does not
directly care about the Value class (it is templated so that the key can
be any arbitrary Value subclass), it is in fact concretely tied to the
Value class through the ValueHandle's CallbackVH interface which relies
on the key type being some Value subclass to establish the value handle
chain.

Ironically, the unittest is already in the right library.

an *indirect* call overhead for every evaluation of the predicate, and

With C++11 we finally have a standardized way to specify atomic operations. Use

26abef7b5a [C++11] Add an iterator_range class template. This is modeled on the
proposed std::iterator_pair which was in committee suggested to move
toward std::iterator_range. There isn't a formal paper yet, but there
seems little disagreement within the committee at this point so it seems
fine to provide our own version in the llvm namespace so we can easily
build range adaptors for the numerous iterators in LLVM's interfaces.

Note that I'm not really comfortable advocating a crazed range-based
migration just yet. The range stuff is still in a great deal of flux in
C++ and the committee hasn't entirely made up its mind (afaict) about
how it will work. So I'm mostly trying to provide the minimal
functionality needed to make writing easy and convenient range adaptors
for range based for loops easy and convenient. ;]

Subsequent patches will use this across the fundamental IR types, where
there are iterator views.

bad91954cf StringRef: Extend constexpr capabilities and introduce ConstStringRef
(1) Add llvm_expect(), an asserting macro that can be evaluated as a constexpr
    expression as well as a runtime assert or compiler hint in release builds. This
    technique can be used to construct functions that are both unevaluated and
    compiled depending on usage.

(2) Update StringRef using llvm_expect() to preserve runtime assertions while
    extending the same checks to static asserts in C++11 builds that support the
    feature.

(3) Introduce ConstStringRef, a strong subclass of StringRef that references
    compile-time constant strings. It's convertible to, but not from, ordinary
    StringRef and thus can be used to add compile-time safety to various interfaces
    in LLVM and clang that only accept fixed inputs such as diagnostic format
    strings that tend to get misused.
