Also, add a FIXME for a bug in PostDomTree calculation I noticed while writing this,

of comparing begin() and end().

use APFloat for int-to-float/double; use
round-to-nearest for these (implementation-defined,
seems to match gcc).

Template-ize more of the DomTree internal implementation details.  Only the calculate() methods for DomTree and PostDomTree remain to be merged/template-ized.

for codegen and used by instcombine.

Convert DFSPass into a templated friend function, in preparation for making it common to DomTree and PostDomTree.

Also eliminated allocas from the Ocaml bindings for portability,

The two remaining unmerged parts are DFSPass, and the Calculate().

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.

this null/not-null logic should be factorized somewhere.

- 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.

LLVM now enforces the following prototypes for the write barriers:

<ty>* @llvm.gcread(<ty2>*, <ty>**)
void @llvm.gcwrite(<ty>*, <ty2>*, <ty>**)

And for @llvm.gcroot, the first stack slot is verified to be an alloca or a 
bitcast of an alloca.

Fixes test/CodeGen/Generic/GC/lower_gcroot.ll, which violated these.

Add a new DenseMapInfo::isEqual method to allow clients to redefine
the equality predicate used when probing the hash table.

double from some of the many places in the optimizers
it appears, and do something reasonable with x86
long double.
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).

Next round of x87 long double stuff.
Getting close now, basically works.

double interfaces where appropriate.
First bits of x86 long double constants handling 
(untested, probably does not work).

of their elements do not yield the same ParamAttrsList,
though they should.  On the other hand, everyone seems
to pass such vectors with elements ordered by increasing
index, so rather than sorting the elements simply assert
that the elements are ordered in this way.

Patch by Sterling Stein!

llvm-svn: 41758

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.)

Update GEP constructors to use an iterator interface to fix
GLIBCXX_DEBUG issues.
