I have some uncommitted changes to the cast code that catch this sort of thing
at compile-time but I still need to do some other cleanup before I can enable
it.

This reverts r171041. This was a nice idea that didn't work out well.
Clang warnings need to be associated with warning groups so that they can
be selectively disabled, promoted to errors, etc. This simplistic patch didn't
allow for that. Enhancing it to provide some way for the backend to specify
a front-end warning type seems like overkill for the few uses of this, at
least for now.

Fix the 'operator==' and 'hasAttributes' queries to take into account
target-dependent attributes.

llvm-svn: 174481

This is useful when parsing an object that references multiple attribute groups.

N.B. If both builders have alignments specified, then they should match!

llvm-svn: 174480

The stuff we're handing are all enums (Attribute::AttrKind), integers and
strings. Don't convert them to Constants, which is an unnecessary step here. The
rest of the changes are mostly mechanical.

Rename the PARAMATTR_CODE_ENTRY to PARAMATTR_CODE_ENTRY_OLD. It will be replaced
by another encoding. Keep around the current LLVM attribute encoder/decoder
code, but move it to the bitcode directories so that no one's tempted to use
them.

Added instance variable/initializers/getter/setters for new keyword externally initialized to GlobalVariable. No *TRUE* functionality change.

I am going to add in the actual test cases with the actual functionality
changes in a later patch because I want to include some test cases.

To be clear when I say no *TRUE* functionality change I mean that this
patch (like it says in the title) only contains getters/setters and sets
up a default initial value of the instance variable to false so that
this patch does not affect any other uses of Global Variable.h.

The main lists of debug info metadata attached to the compile_unit had an extra
layer of metadata nodes they went through for no apparent reason. This patch
removes that (& still passes just as much of the GDB 7.5 test suite). If anyone
can show evidence as to why these extra metadata nodes are there I'm open to
reverting this patch & documenting why they're there.

Use the AttributeSet's iterators in AttrBuilder::hasAttributes() when
determining of the intersection of the AttrBuilder and AttributeSet is non-null.

llvm-svn: 174250

This Constant could be an aggregate to represent multiple values.

llvm-svn: 174228

llvm-svn: 174132

Use iterators instead of relying upon a bitmask of attributes to remove attributes from an AttrBuilder.

llvm-svn: 174123

llvm-svn: 174120

s/AttrBuilder::addAttributes/AttrBuilder::addAttribute/g because that's more descriptive of what it actually is.

llvm-svn: 174116

The AttrBuilder is for building a collection of attributes. The Attribute object
holds only one attribute. So it's not really useful for the Attribute object to
have a creator which takes an AttrBuilder.

This has two fallouts:

1. The AttrBuilder no longer holds its internal attributes in a bit-mask form.
2. The attributes are now ordered alphabetically (hence why the tests have changed).

llvm-svn: 174110

Attributes that are strings are typically target-dependent attributes. They are
of this form in the IR:

   "attr"
   "attr" = "val"

llvm-svn: 174090

That function doesn't make sense anymore because there's only one attribute per
Attribute object now.

llvm-svn: 174044

It broke many hosts to crash.

llvm-svn: 174035

The Attribute::hasAttributes() is kind of meaningless since an Attribute can
have only one attribute. And we would rather people use the 'operator=='
instead of Attribute::hasAttribute().

The AttrBuilder is there to build up multiple attributes. The Attribute class
represents only one attribute at a time. So remove this unnecessary builder
creator method.

llvm-svn: 174010

Several places were still treating the Attribute object as respresenting
multiple attributes. Those places now use the AttributeSet to represent
multiple attributes.

llvm-svn: 174003

for example, a one-past-the-end pointer from one global variable may
be equal to the base pointer of another global variable.
