Bill Wendling 69833b61ac The exception handling function info should be reset for each new
function. The information isn't used heavily -- it's only used at the end
of exception handling emission -- so there's no need to cache it.

Gordon Henriksen 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.

Bill Wendling 067f1d8e95 Objective-C was generating EH frame info like this:
"_-[NSString(local) isNullOrNil]".eh = 0
        .no_dead_strip  "_-[NSString(local) isNullOrNil]".eh

The ".eh" should be inside the quotes.

Devang Patel 267c07b51f Do not eliminate loop when it is invalid to do so. For example,
for(int i = 0; i < N; i++) {
	if ( i == XYZ) {
		A;
	else
		B;
	}
	C;
	D;
}

Gordon Henriksen a2f3e13cf4 Fix for PR1633: Verifier doesn't fully verify GC intrinsics
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.

Dale Johannesen ff7e443792 Remove RSTRegClass case from loadRegFromStackSlot
and storeRegToStackSlot.  Evan and I concluded this
should never be needed and it appears to be true.
(It if is needed, adjustment would be needed for
long double to work.)

Devang Patel 77ae4d358f This is not ideal but unbreaks build failure.
APInt::dump() is inside #ifndef NDEBUG, however SelectionDAG dump() routines are not.

Dan Gohman 863bdc332d Emit integer x<1 as x<=0, as comparisons with zero (now includeing

Dan Gohman 51d1929b9e Use "test reg,reg" in place of "cmp reg,0" for 64-bit operands. This was
previously only done for 32-bit and smaller operands.

Bill Wendling e5615156cc Only emit the personality function as a global value if the backend actually
supports it. This solves this error on the Darwin x86-64 platform:

Dale Johannesen 98d3a08d8f Remove the assumption that FP's are either float or
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.

to/from int, mostly).
