windows-based hosts, where files are opened in text mode by default.

ad0ea2d430 Fix PR1146: parameter attributes are longer part of
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.

67135ebaff Added typedef "SerializedPtrID" to represent the pointer handle written to disk
instead of just using "unsigned".  This gives us more flexibility in changing
the definition of the handle later, and is more self-documenting.

Added tracking of block stack in the Deserializer.  Now clients can query
if they are still within a block using the methods GetCurrentBlockLocation()
and FinishedBlock().

76a0374b25 C bindings for libLLVMCore.a and libLLVMBitWriter.a.
- 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.

bed9dc423c Next round of APFloat changes.
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.)

bdad80977b Patch 10 for long double. Doing constants right needs expanding ConstantFP
to handle values bigger than double.  If we assume host==target and host
long double works correctly, this is not too bad, but we don't want to
have that limitation longterm.  I could implement accepting double
constants as long double or something like that, which would lead to
incorrect codegen with no errors; the more I think about that the worse
it seems.  Rather than do such a hack that would be backed out later,
I'm settling for giving reasonable error messages, for now.
