04f9674857 Add support for 'special' llvm globals like debug info and static ctors/dtors.

9601a86a64 Copysign needs to be expanded everywhere. Note that Alpha and IA64 should 
implement copysign as a native op if they have it.

551bf3f800 kill ADD_PARTS & SUB_PARTS and replace them with fancy new ADDC, ADDE, SUBC 
and SUBE nodes that actually expose what's going on and allow for
significant simplifications in the targets.

45090476be Sparc actually *DOES* have a directive for emitting zeros. In fact, it requires 
it, because this:

.bss
X:
.byte 0

results in the assembler warning: "initialization in bss segment".  Annoying.

6fa1f57c66 Fix SingleSource/Regression/C/2004-08-12-InlinerAndAllocas.c on Sparc. 
The ABI specifies that there is a register save area at the bottom of the
stack, which means the actual used pointer needs to be an offset from
the subtracted value.

69d39091fe Two changes: 
1. Treat FMOVD as a copy instruction, to help with coallescing in V9 mode
2. When in V9 mode, insert FMOVD instead of FpMOVD instructions, as we don't
   ever rewrite FpMOVD instructions into FMOVS instructions, thus we just end
   up with commented out copies!
This should fix a bunch of failures in V9 mode on sparc.

76afdc9a80 First step towards V9 instructions in the V8 backend, two conditional move 
patterns.  This allows emission of this code:

        move %icc, %i0, %i2
        or %g0, %i2, %i0
        restore %g0, %g0, %g0
        retl
        nop

instead of this:

t1:
        save -96, %o6, %o6
        subcc %i0, %i1, %l0
        be .LBBt1_2     !

.LBBt1_1:       !

.LBBt1_2:       !
        restore %g0, %g0, %g0
        retl
        nop

dea9528f7f When lowering SELECT_CC, see if the input is a lowered SETCC. If so, fold 
the two operations together.  This allows us to compile this:

void %two(int %a, int* %b) {
        %tmp.2 = seteq int %a, 0
        %tmp.0.0 = select bool %tmp.2, int 10, int 20
        store int %tmp.0.0, int* %b
        ret void
}

into:

two:
        save -96, %o6, %o6
        or %g0, 20, %l0
        or %g0, 10, %l1
        subcc %i0, 0, %l2

2b4ea795a2 Added field noResults to Instruction. 
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.

171049d10f * Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead. 
* Added a pseudo instruction (for each target) that represent "return void".
  This is a workaround for lack of optional flag operand (return void is not
  lowered so it does not have a flag operand.)

85e42b45ac Reserve G1 for frame offset stuff and use it to handle large stack frames. 
For example, instead of emitting this:

test:
        save -40112, %o6, %o6   ;; imm too large
        add %i6, -40016, %o0    ;; imm too large
        call caller
        nop
        restore %g0, %g0, %g0
        retl
        nop

emit this:

test:
        sethi 4194264, %g1
        or %g1, 848, %g1
        save %o6, %g1, %o6
        sethi 4194264, %g1
        add %g1, %i6, %g1
        add %i1, 944, %o0
        call caller
        nop
        restore %g0, %g0, %g0
        retl
        nop

which doesn't cause the assembler to barf.
