Have any tool can check bottleneck of AOCL?

I want use lookup table to enhance performance. Like the following example,

myCos = cos(); ---------Converted into--------> myCos = checkLutCos();

Change original cosine function into check Lut, but “Performance does not improve”,

Even if Converted cos() into constant zero

myCos = cos(); ---------Converted into--------> myCos = 0;

also not improve

So I think this cosine function isn't in bottleneck.Have any tools can see bottleneck of AOCL?

    I don't have a tool, but I just take loads of measurements, changing types, changing implementations and than comparing those to see which is faster or uses less resources. Though if someone does have a tool, I would like to know about it as wel.
