Ted Kremenek c81614d5d1 Modified ArraySubscriptExpr to have accessors getLHS and getRHS in addition 
to getBase and getIdx.  getBase and getIdx now return a "normalized" view
of the expression (e.g., always "A[4]" instead of possibly "4[A]").  getLHS
and getRHS return the expressions with syntactic fidelity to the original
source code.

Also modified client code of ArraySubscriptExpr, including the AST dumper
and pretty printer, the return-stack value checker, and the LLVM code
generator.

Chris Lattner 6278e6ac30 start splitting out aggregate value computation from EmitExpr into EmitAggExpr. 
aggregate value and scalar expression computation are very different, this
gets them away from each other.  This causes a temporary regression on some
complex number examples.

Chris Lattner 8eab8ff127 fix a codegen bug handling ocuvector element exprs. 
llvm-svn: 40995
 2007-08-10 17:10:08 +00:00
Chris Lattner 90d9120453 implement initial codegen for aggregate return functions. This implements 
codegen for:

_Complex double bar(int);
void test(_Complex double*);

void test2(int c) {
  _Complex double X;
  X = bar(1);
  test(&X);
}

Chris Lattner 81a9688e93 Implement codegen for __builtin_choose_expr. For example: 
struct X { int A; };

void foo() {
  struct X s;
  int i;
  i = __builtin_choose_expr(0, s, i);
}

compiles to:

        %tmp = load i32* %i             ; <i32> [#uses=1]
        store i32 %tmp, i32* %i

wow :)

Chris Lattner 3a44aa7461 implement codegen for multidest ocuvector expressions, like: 
vec2.yx = vec2; // reverse

vec2.x = f;

Chris Lattner fb837dccac In the common case where we are shuffling a vector, emit an 
llvm vector shuffle instead of a bunch of insert/extract operations.
For:   vec4 = vec4.yyyy;  // splat

Emit:
        %tmp1 = shufflevector <4 x float> %tmp, <4 x float> undef, <4 x i32> < i32 1, i32 1, i32 1, i32 1 > 

instead of:

        %tmp1 = extractelement <4 x float> %tmp, i32 1          
        %tmp2 = insertelement <4 x float> undef, float %tmp1, i32 0             
        %tmp3 = extractelement <4 x float> %tmp, i32 1          
        %tmp4 = insertelement <4 x float> %tmp2, float %tmp3, i32 1             
        %tmp5 = extractelement <4 x float> %tmp, i32 1          
        %tmp6 = insertelement <4 x float> %tmp4, float %tmp5, i32 2             
        %tmp7 = extractelement <4 x float> %tmp, i32 1          
        %tmp8 = insertelement <4 x float> %tmp6, float %tmp7, i32 3

Chris Lattner 73ab9b3c14 implement lvalue to rvalue conversion for ocuvector components. We can now compile stuff 
like this:

typedef __attribute__(( ocu_vector_type(4) )) float float4;
float4 test1(float4 V) {
  return V.wzyx+V;
}

to:
_test1:
        pshufd  $27, %xmm0, %xmm1
        addps   %xmm0, %xmm1
        movaps  %xmm1, %xmm0
        ret

and:

_test1:
        mfspr r2, 256
        oris r3, r2, 4096
        mtspr 256, r3
        li r3, lo16(LCPI1_0)
        lis r4, ha16(LCPI1_0)
        lvx v3, r4, r3
        vperm v3, v2, v2, v3
        vaddfp v2, v3, v2
        mtspr 256, r2
        blr
