Updated VC++ build system.
...
Silenced some VC warnings.
I'm getting linker errors, though: unresolved externals:
llvm::Split<class llvm::BasicBlock *,struct llvm::GraphTraits<class llvm::BasicBlock *> >(class llvm::DominatorTreeBase<class llvm::BasicBlock> &,class llvm::BasicBlock *)
and
llvm::Split<struct llvm::Inverse<class llvm::BasicBlock *>,struct llvm::GraphTraits<struct llvm::Inverse<class llvm::BasicBlock *> > >(class llvm::DominatorTreeBase<class llvm::BasicBlock> &,class llvm::BasicBlock *)
Where are these defined?

Add a new function tcExtract for extracting a bignum from an

arbitrary range of bits embedded in the middle of another bignum.
This kind of operation is desirable in many cases of software
floating point, e.g. converting bignum integers to floating point
numbers of fixed precision (you want to extract the precision most
significant bits).
Elsewhere, add an assertion, and exit the shift functions early if
the shift count is zero.

When clearing a SmallPtrSet, if the set had a huge capacity, but the

contents of the set were small, deallocate and shrink the set. This

some pathological cases. For example, this speeds up the verifier
from 0.3899s to 0.0763 (5.1x) on the testcase from PR1432 in a
release build.

Add some things needed by the llvm-gcc version supporting bit accurate integer
...
types:
1. Functions to compute div/rem at the same time.
2. Further assurance that an APInt with 0 bitwidth cannot be constructed.
3. Left and right rotate operations.
4. An exactLogBase2 function which requires an exact power of two or it
returns -1.

Make it illegal to set 0 bits in getHighBitsSet and getLowBitsSet. For that

they should have used the uint64_t constructor. This avoids causing
undefined results via shifts by the word size when the bit width is an
exact multiple of the word size.

In the getBitsSet function, don't optimize for a common case that is
...
already covered by getLowBitsSet (i.e. when loBits==0). Consequently, remove
the default value for loBits and reorder the arguments to the more natural
loBits, hiBits order. This makes it more clear that this function is for bit
groups in the middle of the bit width and not towards one end or the other.
