Is there a way to force array allocation to fill with a specific value, eg NaN? I often find myself debugging bugs that don’t appear when the array happens to be filled with zeros, so this would make these bugs reproducible. I was thinking just overloading the Array constructors might work, but per…

OK, I feel really dumb. This can be written much more concisely like this: using IRTools: @dynamo, IR, recurse!, xcall using IRTools.Inner: Variable, Statement _nan(T::Type{<:AbstractFloat}) = T(NaN) _nan(T) = T(false) debug_array(::Type{<:Array{T}}, ::UndefInitializer, dims...) where T = fill(_…

Make ` Array{T}(undef, ...) ` fill with a value for debugging?

Ah, now I see your problem. You could perhaps write a pass with IRTools.jl
