Evan Cheng 0076ca0da9 - When expanding a bit_convert whose src operand is also to be expanded and 
its expansion result type is equal to the result type of the bit_convert,
e.g. (i64 bit_convert (f64 op)) if FP is not legal
returns the result of the expanded source operand.
- Store f32 / f64 may be expanded to a single store i32/i64.

in some cases.

Chris Lattner a571d211ae testcase for a regression introduced by the recent cast patch 
llvm-svn: 32419
 2006-12-11 00:12:07 +00:00
Chris Lattner 216c3028e6 * Eliminate calls to CastInst::createInferredCast. 
* Add support for promoting unions with fp values in them.  This produces
   our new int<->fp bitcast instructions, implementing
   Transforms/ScalarRepl/union-fp-int.ll

As an example, this allows us to compile this:

union intfloat { int i; float f; };
float invsqrt(const float arg_x) {
    union intfloat x = { .f = arg_x };
    const float xhalf = arg_x * 0.5f;
    x.i = 0x5f3759df - (x.i >> 1);
    return x.f * (1.5f - xhalf * x.f * x.f);
}

into:

_invsqrt:
        movss 4(%esp), %xmm0
        movd %xmm0, %eax
        sarl %eax
        movl $1597463007, %ecx
        subl %eax, %ecx
        movd %ecx, %xmm1
        mulss LCPI1_0, %xmm0
        mulss %xmm1, %xmm0
        movss LCPI1_1, %xmm2
        mulss %xmm1, %xmm0
        subss %xmm0, %xmm2
        movl 8(%esp), %eax
        mulss %xmm2, %xmm1
        movss %xmm1, (%eax)
        ret

instead of:

_invsqrt:
        subl $4, %esp
        movss 8(%esp), %xmm0
        movss %xmm0, (%esp)
        movl (%esp), %eax
        movl $1597463007, %ecx
