05b15fb075 TargetCacheInfo has been removed; its only uses were to propagate a constant
(16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's
dcache has 32-byte lines, so I'm not sure where the 16 came from. However, in
the interest of not breaking things any more than they already are, I'm going
to leave the constant alone.

c0b9dc5be7 Change MachineBasicBlock's vector of MachineInstr pointers into an
ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
MachineBasicBlock. It also allows for constant time splicing of
MachineInstrs into or out of MachineBasicBlocks.

07ad64231f Eliminate the isStringCompatible function, using ConstantArray::isString.
It's not clear why the code was looking for signed chars < 0, but it can't
matter to the assembler anyway, so the check goes away.  This also fixes
compatibility with arrays of [us]byte that have constantexprs in them.

Also slightly restructure some code to be cleaner.

4d7af65903 Change interface of MachineOperand as follows:
a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse()
    b) add isUse(), isDef()
    c) rename opHiBits32() to isHiBits32(),
              opLoBits32() to isLoBits32(),
              opHiBits64() to isHiBits64(),
              opLoBits64() to isLoBits64().

This results to much more readable code, for example compare
"op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used
very often in the code.

6275a04768 Substantially re-organized this file:
* There is now only one pass to print out assembly instead of two
* It is a FunctionPass
* The Module-level printing of globals is now in doFinalization() method of the
  FunctionPass
* The code has been reformatted to follow LLVM coding standards
* Some comments, not all, were doxygenified
* Last but not least, the function to create an instance of this pass is also no
  longer a method in the UltraSparc class.

printing out Sparc assembly. In fact, they should share all this code anyway.

72666e6c30 Add all arithmetic operators to ConstantExprToString().
Note that some generated operators (like &, | or ^) may
not be supported by the assembler -- but if they've got
this far, it's better to generate them and let the assembler decide.

b15f8d446a Several fixes to handling of int CC register:
(1) An int CC live range must be spilled if there are any interferences,
    even if no other "neighbour" in the interf. graph has been allocated
    that reg. yet.  This is actually true of any class with only one reg!

(2) SparcIntCCRegClass::colorIGNode sets the color even if the LR must
    be spilled so that the machine-independent spill code doesn't have to
    make the machine-dependent decision of which CC name to use based on
    operand type: %xcc or %icc.  (These are two halves of the same register.)

(3) LR->isMarkedForSpill() is no longer the same as LR->hasColor().
    These should never have been the same, and this is necessary now for #2.

(4) All RDCCR and WRCCR instructions are directly generated with the
    phony number for %ccr so that EmitAssembly/EmitBinary doesn't have to
    deal with this.

bb6b121689 Allow emission of names that start with an underscore. This is needed to
interface with code that uses symbols in the ansi-c protected namespace.  In
most cases this comes from system header files, such as stdio.h.  In particular,
without this change, a reference to the __iob symbol is mangled into ll_iob,
which is not resolved by libc.

fee76265ff Several major fixes, particularly in emitting constant aggregates:
(1) Padding bytes between structure fields (for alignment) were never
    being emitted into the constant pool so the layout did not match!
(2) In printing constants, structures containing structures or arrays
    were never handled.
(3) Support new model for external/uninitialized/initialized globals.
    Uninitialized globals are no longer emitted since they are external.
    Initialized globals may go either in .bss or in .data.
