Is it possible to enable OVERLAYING just for some given procedures and disable for all others?
"Since I use function pointers heavily, I've already disabled overlaying fully." Note that you don't have to disable overlaying to use function pointers. The problem with function pointers in C51 is that the Linker can't work out the call-tree automatically - but you can still specify it manually, which will then let the Linker do the overlaying! See App Note 129, Function Pointers in C51 and http://www.keil.com/support/docs/210.htm
