I would like to be able to emit a list of functions by name and their fixed stack reservation size information, so that a programmer can gauge how much stack they are likely to need in tightly constrained embedded systems. Despite the rich number of options, the only option I can find that is even relatively close is: -warn-stack-size=<uint> Is there some existing way of getting this
