[llvm-dev] Dumping the static stack reservation sizes for functions

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:




Is there some existing way of getting this information emitted in an easily
parsable way (e.g. in CSV form) , or will I need to add the capability?
