Details
The interpreter is not properly negating a float4(0f) but will properly negate a float4(-0f)
Code:
var flt4zero:float4 = new float4(0f);
print(1/flt4zero.x);
flt4zero = -flt4zero;
print(1/flt4zero.x);
var neg_flt4zero:float4 = new float4(-0f);
print(1/neg_flt4zero.x);
neg_flt4zero = -neg_flt4zero;
print(1/neg_flt4zero.x);
Output with -Dinterp:
float4
Infinity
Infinity
-Infinity
Infinity
Expected Output and output when using -Ojit:
float4
Infinity
-Infinity
-Infinity
Infinity

Fixed this, but it's now a bug in ASC (doesn't recognize the difference between float4(0f) and float4(-0f) )

Is there an asc bug entered for this? If not I will enter one.

nope; it's only in the latest ASC, I think.
