I've used @code_warntype everywhere I can think to and I've only found one
Core.box. The @code_warntype looks like this
Variables:
#self#::#innerloop#3133{#bellman_obj}
state::State{IdioState,AggState}
EVspline::Dierckx.Spline1D
model::Model{CRRA_Family,AggState}
policy::PolicyFunctions{Array{Float64,6},Array{Int64,6}}
OO::NW
#3130::##3130#3134{State{IdioState,AggState},Dierckx.Spline1D,Model{CRRA_Family,AggState},PolicyFunctions{Array{Float64,6},Array{Int64,6}},NW,#bellman_obj}
Body:
begin
#3130::##3130#3134{State{IdioState,AggState},Dierckx.Spline1D,Model{CRRA_Family,AggState},PolicyFunctions{Array{Float64,6},Array{Int64,6}},NW,#bellman_obj}
= $(Expr(:new,
##3130#3134{State{IdioState,AggState},Dierckx.Spline1D,Model{CRRA_Family,AggState},PolicyFunctions{Array{Float64,6},Array{Int64,6}},NW,#bellman_obj},
:(state), :(EVspline), :(model), :(policy), :(OO),
:((Core.getfield)(#self#,:bellman_obj)::#bellman_obj)))
SSAValue(0) =
#3130::##3130#3134{State{IdioState,AggState},Dierckx.Spline1D,Model{CRRA_Family,AggState},PolicyFunctions{Array{Float64,6},Array{Int64,6}},NW,#bellman_obj}
(Core.setfield!)((Core.getfield)(#self#::#innerloop#3133{#bellman_obj},:obj)::CORE.BOX,:contents,SSAValue(0))::##3130#3134{State{IdioState,AggState},Dierckx.Spline1D,Model{CRRA_Family,AggState},PolicyFunctions{Array{Float64,6},Array{Int64,6}},NW,#bellman_obj}
return SSAValue(0)
end::##3130#3134{State{IdioState,AggState},Dierckx.Spline1D,Model{CRRA_Family,AggState},PolicyFunctions{Array{Float64,6},Array{Int64,6}},NW,#bellman_obj}
I put the CORE.BOX in all caps near the bottom.
I have no idea if this is actually a problem. The return type is stable.
Also, this function appears in an outer loop.
What I noticed putting a @time in places is that in 0.5, occasionally calls
to my nonlinear equation solver take a really long time, like here:
