I don’t have a small MWE to generate it, but I occasionally see “deoptimized” in the menu of Cthulhu.jl, e.g.
Advanced: dump [P]arams cache.
%3 = invoke alias_continue(…,…,…)::Any
%4 = call #!(::Any)::Any
%25 = invoke push!(::typename(DiscretePathSearch.NodeHandle){…},::typename(DiscretePathSearch.NodeAugmentation){…})::Any
%31 = invoke throw_inexacterror(::Symbol,::Type{Int32},::Int64)::Union{}
%40 = invoke error(::String)::Union{}
%56 = invoke alias_tally!(…,…,…)::Any
%78 = call ArgumentError(::String)::Any
%115 = invoke throw_inexacterror(::Symbol,::Type{UInt64},::Int64)::Union{}
• %133 = deoptimized successors!(::typename(DiscretePathSearch.PathAndSummary){…},::typename(DiscretePathSearch.Algorithm){…})::Any
What does this mean? I tried searching for “deoptimized” (in Julia and in Cthulh) and I cannot even see what code emits it.
I opened an issue to document it, but figured I should ask here too, since its meaning is not Cthulhu specific
