Owen Anderson 20a631fde7 Refactor TargetMachine, pushing handling of TargetData into the target-specific subclasses. This has one caller-visible change: getTargetData() now returns a pointer instead of a reference.
This fixes PR 759.

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 326870b40b Codegen insertelement with constant insertion points as scalar_to_vector
and a shuffle.  For this:

void %test2(<4 x float>* %F, float %f) {
        %tmp = load <4 x float>* %F             ; <<4 x float>> [#uses=2]
        %tmp3 = add <4 x float> %tmp, %tmp              ; <<4 x float>> [#uses=1]
        %tmp2 = insertelement <4 x float> %tmp3, float %f, uint 2               ; <<4 x float>> [#uses=2]
        %tmp6 = add <4 x float> %tmp2, %tmp2            ; <<4 x float>> [#uses=1]
        store <4 x float> %tmp6, <4 x float>* %F
        ret void
}

we now get this on X86 (which will get better):

_test2:
        movl 4(%esp), %eax
        movaps (%eax), %xmm0
        addps %xmm0, %xmm0
        movaps %xmm0, %xmm1
        shufps $3, %xmm1, %xmm1
        movaps %xmm0, %xmm2
        shufps $1, %xmm2, %xmm2
        unpcklps %xmm1, %xmm2
        movss 8(%esp), %xmm1
        unpcklps %xmm1, %xmm0
        unpcklps %xmm2, %xmm0
        addps %xmm0, %xmm0
        movaps %xmm0, (%eax)
        ret

instead of:

_test2:
        subl $28, %esp
        movl 32(%esp), %eax
        movaps (%eax), %xmm0
        addps %xmm0, %xmm0
        movaps %xmm0, (%esp)
        movss 36(%esp), %xmm0
        movss %xmm0, 8(%esp)
        movaps (%esp), %xmm0
        addps %xmm0, %xmm0
        movaps %xmm0, (%eax)
        addl $28, %esp
        ret

Evan Cheng 78e3d565af INSERT_VECTOR_ELT lowering bug:
store vector to $esp
  store element to $esp + sizeof(VT) * index
  load  vector from $esp
The bug is VT is the type of the vector element, not the type of the vector!

Chris Lattner 6be79823e7 * Add supprot for SCALAR_TO_VECTOR operations where the input needs to be
promoted/expanded (e.g. SCALAR_TO_VECTOR from i8/i16 on PPC).
* Add support for targets to request that VECTOR_SHUFFLE nodes be promoted
  to a canonical type, for example, we only want v16i8 shuffles on PPC.
* Move isShuffleLegal out of TLI into Legalize.
* Teach isShuffleLegal to allow shuffles that need to be promoted.
