Anders Carlsson f087c0c1c6 Add preliminary support for converting struct types. 
llvm-svn: 41145
 2007-08-17 22:00:32 +00:00
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 d79671fdf2 New file, just a placeholder for now.

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 02697701d9 Fix a bug handling function -> pointer decay and avoid emitting a noop 
bitcast.

Chris Lattner 87f4836184 now that implicit conversions are explicit, we can eliminate 
EmitUsualArithmeticConversions.

Chris Lattner 5ebb2fed89 now that implicit conversions are explicit, we can eliminate

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 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

 2007-08-03 15:52:31 +00:00
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

Chris Lattner 651f0e9c8f Add a hack (mirroring llvm-gcc) to pointer difference 
codegen to compile:

int test(int *A, int *B) {
  return A-B;
}

into:

_test:
        movl 4(%esp), %eax
        subl 8(%esp), %eax
        sarl $2, %eax
        ret

        subl 8(%esp), %eax
        movl %eax, %ecx
        sarl $31, %ecx
