Warren Hunt 5d9eebfec6 [MS-ABI] Fixed __declspec(align()) on bitfields under #pragma pack.
When __declspec(align()) is applied to a bitfield it affects the 
alignment rather than the required alignment of the struct.  The major 
feature that this patch adds is that the alignment of the structure 
obeys the alignment of __declspec(align()) from the bitfield over the 
value specified in pragma pack.

Test cases are included.
The patch also includes some small cleanups in recordlayoutbuilder and 
some cleanups to some lit tests, including line endings (but no 
functionality change to lit tests)

David Blaikie 1ecafa8808 Simplify make_range by using move semantics
Move the iterators into the range the same way the range's ctor moves
them into the members.

Also remove some redundant top level parens in the return statement.

David Blaikie 8019bf815d Reimplement debug info compression by compressing the whole section, rather than a fragment.
To support compressing the debug_line section that contains multiple
fragments (due, I believe, to variation in choices of line table
encoding depending on the size of instruction ranges in the actual
program code) we needed to support compressing multiple MCFragments in a
single pass.

This patch implements that behavior by mutating the post-relaxed and
relocated section to be the compressed form of its former self,
including renaming the section.

This is a more flexible (and less invasive, to a degree) implementation
that will allow for other features such as "use compression only if it's
smaller than the uncompressed data".

Compressing debug_frame would be a possible further extension to this
work, but I've left it for now. The hurdle there is alignment sections -
which might require going as far as to refactor
MCAssembler.cpp:writeFragment to handle writing to a byte buffer or an
MCObjectWriter (there's already a virtual call there, so it shouldn't
add substantial compile-time cost) which could in turn involve
refactoring MCAsmBackend::writeNopData to use that same abstraction...
which involves touching all the backends. This would remove the limited
handling of fragment writing seen in
ELFObjectWriter.cpp:getUncompressedData which would be nice - but it's
more invasive.

I did discover that I (perhaps obviously) don't need to handle
relocations when I rewrite the fragments - since the relocations have
already been applied and computed (and stored into
ELFObjectWriter::Relocations) by this stage (necessarily, because we
need to have written any immediate values or assembly-time relocations
into the data already before we compress it, which we have). The test
case doesn't necessarily cover that in detail - I can add more test
coverage if that's preferred.

David Blaikie 4d3b043542 Revert debug info compression support.
To support compression for debug_line and debug_frame a different
approach is required. To simplify review, revert the old implementation
and XFAIL the test case. New implementation to follow shortly.

Reverts r205059 and r204958.

blessing, it will be replaced by the official version.

Kevin Enderby 488f20b64e For the ARM integrated assembler add checking of the
alignments on vld/vst instructions.  And report errors for
alignments that are not supported.

While this is a large diff and an big test case, the changes
are very straight forward.  But pretty much had to touch
all vld/vst instructions changing the addrmode to one of the
new ones that where added will do the proper checking for
the specific instruction.

FYI, re-committing this with a tweak so MemoryOp's default
constructor is trivial and will work with MSVC 2012. Thanks
to Reid Kleckner and Jim Grosbach for help with the tweak.

Adrian Prantl bad6b83506 Revert "Follow-up to r205973: change the return type to const MDNode*."
This reverts commit r205974, it turns out that this wasn't such a great idea

Enrico Granata bd4885f129 <rdar://problem/16540961>
The "unexpected value" message only matters to me, but is bound to make the experience more confusing for people when some uninitialized memory looks like an NSNumber and then can't be formatted properly, and that error comes out in the UI

Just drop the error message entirely - nobody but me cares

Eric Christopher cab9fae403 Add global static variables for anonymous union fields. This makes
sure that a debugger can find them when stepping through code,
for example from the included testcase:

   12     int test_it() {
   13       c = 1;
   14       d = 2;
-> 15       a = 4;
   16       return (c == 1);
   17     }
   18
(lldb) p a
(int) $0 = 2
(lldb) p c
(int) $1 = 2
(lldb) p d
(int) $2 = 2

and a, c, d are all part of the file static anonymous union:

static union {
  int c;
  int d;
  union {
    int a;
  };
  struct {
    int b;
  };
};
