Actually no. Go compiler already has "stack promotion" (using "escape analysis"). TOC is in addition to that and I think it's intended to cover the cases not covered by "stack promotion" for example Function A calls Function B which allocates some memory and returns it to Function A which "consumes it" before returning. In this case the allocation can't be promoted to stack because B returns and its stack gets destroyed.. but the allocated memory can still be safely released when Function A returns.
