e35b8fabc4 * Simplify printConstantValueOnly by moving the tail padding stuff directly
into the struct case.
* Extend printConstantValueOnly to print .zero's if the initializer is zero
* Delete dead isConstantFunctionPointerRef function
* Emit the appropriate assembly for the various linkage types!

a735c79a1b Factory methods for FunctionPasses now return type FunctionPass *.
Revert (to v1.55) one of the hunks of Chris's change that messed up the
 %-register workaround.

84e5185cbd Add a new -enable-cygwin-compatible-output argument, which make the output more
consumably by the cygwin assembler.  This is really just a nasty hack until we
get real target triple support.

e599cf3856 Print % signs before register names; turn off "noprefix" mode in gas output.
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.

96704b97ca * Sort #includes, remove dupliates
* Use .zero to emit padding between struct elements
* 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.

4449b3c963 I think local symbols in X86 GAS have to start with .L, not just
.; so I have changed the basic block markers to start with .L.  I also
broke up a >80char line.

dc07ea6681 Use unified CWriter-X86/Printer name mangler. Do not bother using
SlotCalculator in CWriter.  (Unfortunately, all this means a lot of
X86/Printer's methods have to be de-constified again.  Oh well.)

4afe7aea5f 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.

5674309dc1 Printer.cpp: Ditch addRequired/getAnalysis, because they leave
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().

9de468d398 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.

89ce6ca0a6 If we have a constant pointer reference to a function, we were printing
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.)

efd836df31 Fix some serious floating-point bugs (fixes test cases such as Oscar,
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.

6f2c46cd52 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.

beb320af87 Add Initialization and Finalization methods for the Printer pass,
to print various things on a module-by-module basis (currently, only the
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.

dbc34a2a95 Target/X86/Printer.cpp: Add sizePtr function, and use it instead of
" <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.
 (MemArg16, MemArg32, MemArg64, etc.)
