Some of the systems the Small Device C compiler targets have just 60 B of RAM. And we are curetnly considering adding support for a multicore microcontroller, of which also variants with just 60 B of RAM exist. But even for the other architectures supported in SDCC, where devices tend to have much bigger RAM, in the range of 128B to even a few KB, wasting memory like that is not acceptable. Philipp
