other than PPC64. Instead of fixing it, just remove it and fix all the
places that use it to use TargetData::getPointerSize() instead, as there
aren't very many. Most of the references were in DwarfWriter.cpp.

It includes:
- location and of each safe point in machine code (identified by a
label)
- location of each root within the stack frame (identified by an
offset), including the metadata tag provided to llvm.gcroot in
the user program
- size of the stack frame (for collectors which want to cheat on
stack crawling :)
- and eventually will include liveness
It is to be populated by back-ends during code-generation.
CollectorModuleMetadata aggregates this information across the
entire module.

instruction creation. No support yet for instruction introspection.
Also eliminated allocas from the Ocaml bindings for portability,
and avoided unnecessary casts.

Fixup operator == to make this work, and add a resize method to DenseMap
so we can resize our hashtable once we know how big it should be.

change is not useful in and of itself, but it lays the groundwork for combining
the dominator and postdominator implementations.
Also, factor a few methods that are common to DominatorTree and PostDominatorTree
into DominatorTreeBase. Again, this will make merging the two calculation methods
simpler in the future.

is effectively a new codegen mode.
Change addLegalFPImmediate to permit float and
double variants to do different things.
Adjust callers.

bit width instead of number of words allocated, which
makes it actually work for int->APF conversions.
Adjust callers. Add const to one of the APInt constructors
to prevent surprising match when called with const
argument.

returned a reference type. This patch allows operator*() to return a
non-reference type while still maintaining the old behavior when it
does return a reference type.
This patch was motivated when I tried to use "df_iterator" (see
llvm/ADT/DepthFirstIterator.h) as a "node_iterator", as df_iterator
does not return a reference type and thus we would get a compilation
error when trying to take the address of a temporary.

of exception handling emission -- so there's no need to cache it.

- The naming prefix is LLVM.
- All types are represented using opaque references.
- Functions are not named LLVM{Type}{Method}; the names became
unreadable goop. Instead, they are named LLVM{ImperativeSentence}.
- Where an attribute only appears once in the class hierarchy (e.g.,
linkage only applies to values; parameter types only apply to
function types), the class is omitted from identifiers for
brevity. Tastes like methods.
- Strings are C strings or string/length tuples on a case-by-case
basis.
- APIs which give the caller ownership of an object are not mapped
(removeFromParent, certain constructor overloads). This keeps
keep memory management as simple as possible.
For each library with bindings:
llvm-c/<LIB>.h - Declares the bindings.
lib/<LIB>/<LIB>.cpp - Implements the bindings.
So just link with the library of your choice and use the C header
instead of the C++ one.

GCC optimizes away things like ptr < NULL to false. To "fix" this,

Make APInt::dump() public, remove newline, use it to
dump ConstantSDNode's.
Allow APFloats in FoldingSet.
Expand X86 backend handling of long doubles (conversions
to/from int, mostly).

Use APFloat in UpgradeParser and AsmParser.
Change all references to ConstantFP to use the
APFloat interface rather than double. Remove
the ConstantFP double interfaces.
Use APFloat functions for constant folding arithmetic
and comparisons.
(There are still way too many places APFloat is
just a wrapper around host float/double, but we're
getting there.)
