not yet clear why, but in the meantime work around the
problem by making less use of readnone/readonly info.

throw exceptions", just mark intrinsics with the nounwind
attribute. Likewise, mark intrinsics as readnone/readonly
and get rid of special aliasing logic (which didn't use
anything more than this anyway).

attributes. While there, I noticed that not all
attribute methods returned a pointer-to-constant,
so I fixed that.

the function type, instead they belong to functions
and function calls. This is an updated and slightly
corrected version of Reid Spencer's original patch.
The only known problem is that auto-upgrading of
bitcode files doesn't seem to work properly (see
test/Bitcode/AutoUpgradeIntrinsics.ll). Hopefully
a bitcode guru (who might that be? :) ) will fix it.

trivial difference in function attributes, allow calls to it to
be converted to direct calls. Based on a patch by Török Edwin.
While there, move the various lists of mutually incompatible
parameters etc out of the verifier and into ParameterAttributes.h.

any sense it is important that ParamAttr::None gets
treated the same as not supplying an attribute at
all. Rather than stripping ParamAttr::None out of
the list of attributes, assert if ParamAttr::None
is seen. Fix up the bitcode reader which liked to
insert ParamAttr::None all over the place. Patch
based on one by Török Edwin.

doing something - this needs to work for release builds
too. I chose to just abort rather than following the
fancy logic of abortIfBroken, because (1) it is a pain
to do otherwise, and (2) nothing is going to work if the
module is this broken.

ConstantVector or ConstantAggregateZero.

codegen support. This should have no effect on codegen
for other types. Debatable bits: (1) the use (abuse?)
of a set in SDNode::getValueTypeList; (2) the length of
getTypeToTransformTo, which maybe should be refactored
with a non-inline part for extended value types.

No compile-time support for constant operations yet,
just format transformations. Make readers and
writers work. Split constants into 2 doubles in
Legalize.

modified the function to expect zero-extended input. Make this
assumption explicit in the function name.

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

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

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.

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).

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.

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.)

This eliminates a conditional on that path, and ensures ICmpInst/FCmpInst
both have an out-of-line virtual method to home the class.
