Verify that function has been compiled?

Hi all,

In order to decrease a GC pressure during training of machine learning models, we override the default julia allocator for arrays, such that these arrays are created inside the pre- allocated buffer, which is scrapped after each iteration. It seems to work for us rather good, but I am afraid this solution to be a bit fragile. For example I do not know, how this might interfere with Julia compiler, if I by accident hit a function which needs to be compiled ( our data are not tensors and they can come in many types due to missing values). I would like to therefore ask, if there is a some way to verify, that Julia has already seen this function with such combination of arguments.

Thanks for the answer,
Tomas

MethodAnalysis allows you to ask these kinds of questions. You can search for MethodInstances (which are the result of running type-inference) or CodeInstances (which are the result of complete compilation).
