We have a embedded software project running on 80C51. We meet tight code size issue to fit in 64KB. We wants to use optimize option in C compiler. But when we add ot(6,size) in makefile, the DOS promopt us some source code is :Program too big to fit. So we can not use it now.
The Keil C51 is V7.02, runing in Windows XP SP2, DOS prompt memory deepth is 32KB.
Does anyone knows about this?
