Add support for the llvm.unwind intrinsic, which we codegen to just do an abort
...
until we implement unwinding.
Add support for the invoke instruction, which codegens just like a call with
a branch after it.
The end effect of this change is that programs using the invoke instruction,
but never unwinding, will work fine. Programs that unwind will abort until
we get unwind support.

other things, but only if the LLVM code shared data structures with native code.

Constify most methods. We could have constified doInitialization and

doFinalization too except that would have made them shadow, not override,
the parent class :-P.
Allow *any* constant cast expression between pointers and longs,
or vice-versa, or any widening (not just same-size) conversion that
isLosslesslyConvertibleTo approves. This fixes oopack.

Printer.cpp: Ditch addRequired/getAnalysis, because they leave

Don't pass TargetMachine or MRegisterInfo objects around in the Printer.

Add, rewrite, and/or reformat many comments.
...
Stop passing ostreams around: we already have one perfectly good ostream
and we can all share it.
Stop stashing a pointer to TargetData in the Pass object, because that will
lead to a crash if there are no functions in the module (ouch!) Instead,
use addRequired() and getAnalysis(), like we always should have done.
Move the check for ConstantExpr up before the check for isPrimitiveType,
because we need to be able to catch e.g. ubyte (cast bool false to ubyte),
whose type is primitive but which is nevertheless a ConstantExpr, by calling
our specialized handler instead of the AsmWriter. This would result in
assembler errors when we would try to output something like ".byte (cast
bool false to ubyte)".
GC some unused variable declarations.

Avoid a fall-through in the (stubby) treatment of the longjmp intrinsic
call which causes llc & lli to core-dump.
Add a sort-of treatment of cast double to ulong. I am not really sure
what a user should expect to see upon casting a negative FP value to
unsigned long long. But with what is given here, I was able to write
a program that could cast -123.456 to ulong and back and get -123.0,
which seems like a step in the right direction. GCC seems to give you
0. I don't know if I'd consider that useful.
These cases were coming up in GNU coreutils-5.0.

Nice tasty llc fixes. These should fix LLC for x86 for everything in
...
SingleSource except oopack and Oscar. (Sorry, Oscar.)
include/llvm/Target/TargetInstrInfo.h: Remove virtual print method. Add
accessors for ImplicitUses/Defs.
lib/Target/TargetInstrInfo.cpp: Remove virtual print method. If you
really wanted this, just use MI->print(O, TM); instead...
lib/Target/X86:
FloatingPoint.cpp: ...like this.
X86InstrInfo.h: Remove virtual print method. Define the PrintImplUses
target-specific flag bit.
X86InstrInfo.def: Add the PrintImplUses flag to all the instructions
which implicitly use CL, because the assembler needs to see the CL in
order to generate the right instruction.
Printer.cpp: Ditch fnIndex at Chris's request. Now we use CurrentFnName
to name constants in the constant pool for each function instead. This
avoids keeping state between runOnMachineFunction() invocations, which
is a no-no. Having MangledGlobals be global is a bogon I'd like to get
rid of too, but making it a static member of Printer causes link errors
(why???).
Make NumberForBB into a member of Printer instead of a global, too.
Make printOp and printMemReference into methods of Printer.
X86InstrInfo::print is now Printer::printMachineInstruction, because
TargetInstrInfo::print is history. (Because of this, we have to qualify
the names of some TargetInstrInfo methods we call.)
Print out the ImplicitUses field of any instruction we print that has
the PrintImplUses bit set.
