Jim Laskey dce07568f2 Alignment of globals has not been quite right. Needed to drop the pointer type
to get the alignment of the element type.

Nate Begeman 4ca2ea5b43 JumpTable support! What this represents is working asm and jit support for
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.

Chris Lattner aa23fa9f43 Implement smart printing of inline asm strings, handling variants and

int %test(int %A, int %B) {
  %C = call int asm "xyz $0, $1, $2", "=r,r,r"(int %A, int %B)
  ret int %C
}

we now emit:

_test:
        or r2, r3, r3
        or r3, r4, r4
        xyz r2, r2, r3  ;; look here

Nate Begeman 41b1cdc771 Teach the SelectionDAG ISel how to turn ConstantPacked values into
constant nodes with vector types.  Also teach the asm printer how to print
ConstantPacked constant pool entries.  This allows us to generate altivec
code such as the following, which adds a vector constantto a packed float.

LCPI1_0:  <4 x float> < float 0.0e+0, float 0.0e+0, float 0.0e+0, float 1.0e+0 >
        .space  4
        .space  4
        .space  4
        .long   1065353216      ; float 1
        .text
        .align  4
        .globl  _foo
_foo:
        lis r2, ha16(LCPI1_0)
        la r2, lo16(LCPI1_0)(r2)
        li r4, 0
        lvx v0, r4, r2

        vaddfp v0, v1, v0
        stvx v0, r4, r3
        blr

For the llvm code:

void %foo(<4 x float> * %a) {
entry:
  %tmp1 = load <4 x float> * %a;
  %tmp2 = add <4 x float> %tmp1, < float 0.0, float 0.0, float 0.0, float 1.0 >

Chris Lattner 55a6d9067b add support for .asciz, and enable it by default. If your target assemblerdoesn't support .asciz, just set AscizDirective to null in your asmprinter.
This compiles C strings to:

l1__2E_str_1:                           ; '.str_1'
        .asciz  "foo"

instead of:

Duraid Madina 73a316d712 add support for prefix/suffix strings to go around GlobalValue(s)

this changes nothing, except the IA64 backend which can use this to write:

Chris Lattner 145569b076 Print GEP offsets as signed values instead of unsigned values. On X86, this

getelementptr (int* %A, int -1)

assembler much happier.

with emitting .xwords when not on an 8-byte boundary (.xword 0 is not the

just emit bytes like the old V9 asmprinter did.
