strings with the stuff that used to print to an ostream directly. We now NEVER build
up big strings, only to print them once they are formed.

extra copy into a register, reducing register pressure.

Fixes test case test/Programs/LLVMSource/2003-08-03-ReservedWordGlobal.ll.
Also: Refactor implicit-uses printing into its own method.
Remove a couple of unused variables.

* Emit .comm symbols when we can, this dramatically reduces the amount of gunk we have to print
* Print global variable identifiers next to initializer more nicely.

SlotCalculator in CWriter. (Unfortunately, all this means a lot of
X86/Printer's methods have to be de-constified again. Oh well.)

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::doFinalization() out in the cold. Now we pass in a TargetMachine
to Printer's constructor and get the TargetData from the TargetMachine.
Don't pass TargetMachine or MRegisterInfo objects around in the Printer.
Constify TargetData references.
X86.h: Update comment and prototype of createX86CodePrinterPass().
X86TargetMachine.cpp: Update callers of createX86CodePrinterPass().

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.

out the entire llvm disassembly for the function at global constant-output
time, which caused the assembler to barf in 164.gzip. This fixes that
particular problem (though 164.gzip has other problems with X86 llc.)

Fhourstones, McCat-vor, and many others...)
Printer.cpp: Print implicit uses for AddRegFrm instructions. Break gas
bug workarounds up into separate stanzas of code for each bug. Add new
workarounds for fild and fistp.
X86InstrInfo.def: Add O_ST0 implicit uses for more FP instrs where they
obviously apply. Also add PrintImplUses flags for FP instrs where they
are necessary for gas to understand the output.

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.

former is used).
Don't print < > around names. The assembler can't take it.
Print pseudoinstructions only as comments. The poor little assembler can't
take that, either.

" <SIZE> PTR " string when emitting assembly.
Target/X86/X86InstrInfo.def: Tidy up a bit:
Squashed everything down to 118 chars wide, wrapping lines so that
comment is at the same point on each line. Rename "NoImpRegs" as
"NoIR". (most instructions have NoImpRegs twice on a line, so this
saves 10 columns).
Also, annotate various instructions with flags for size of memory operand.
(MemArg16, MemArg32, MemArg64, etc.)
Target/X86/X86InstrInfo.h: Define flags for size of memory operand.

lib/Target/X86/InstSelectSimple.cpp: Explicitly specify some implicit uses.
Use MOVZX/MOVSX instead of MOV instructions with sign extend instructions.
Take out LEAVE instructions.
32-bit IDIV and DIV use CDQ, not CWQ (CWQ is a typo).
Fix typo in comment and remove some FIXME comments.
lib/Target/X86/Printer.cpp: Include X86InstrInfo.h and llvm/Function.h.
Add some simple code to Printer::runOnFunction to iterate over
MachineBasicBlocks and call X86InstrInfo::print().
lib/Target/X86/X86InstrInfo.def: Make some more instructions with
implicit defs "Void". Add more sign/zero extending "move" insns
(movsx, movzx).
lib/Target/X86/X86RegisterInfo.def: Add EFLAGS as a register.
