Read-Only Author David Fussell Posted 11-Apr-2003 07:49 Toolset C51	Relocating library program segments David Fussell In an attempt to free some code space, I'm considering the wisdom of relocating some library program segments from the common code area into one of my two banks. I'm a bit reluctant to do this for library functions (PRINTF, etc), but I'm assuming that any directive relocating these program segments is detected at link time, so the appropriate bank switch code will be inserted around calls to these functions as necessary. I appreciate the slight performance 'hit' resulting from this action, but needs must etc... Is this a wise thing to consider?

Read-Only Author David Fussell Posted 9-Feb-2004 08:12 Toolset C51	RE: Relocating library program segments David Fussell I'd look at the map file to obtain segment names etc, and use either the CODE directive to move them around in the 'common area', or alternatively, for banking, via the approprite 'BANK' directive.
