Ooops, I'd prefer rather not to. And think I have some objections:) a) I think the increased resource usage will be seen as a major regression for users - migrating from earlier versions of SDCC to 2.9.x versions (with one of these memory models). Expect postings like: "using latest version of SDCC significantly increased code size" - migrating from small memory models to one of the larger models will result in an disproportionate code memory increase being seen. - migrating from other compilers towards SDCC. Note, for the other compiler the source might fit into small memory model while SDCC might require large model so the size difference can be so Huge as to be discouraging. "the evaluation version of the commercial compiler allowed only 4 kByte code. To see whether SDCC would be an option I threw the code at SDCC, couldn't use the small memory there and ended up with x kByte - giving up." b) Additionally I do not like the thought of functionality being changed just because the memory model is switched (should be as orthogonal to anything as can be). "... switched to small memory model and my floating point application ..." c) Plus there is a reasonably friendly printf output: "<no float>" in case of the non-floating point version of printf being used for floats. (we hardly can warn the other way round) Could there be a compiler option like -lPleaseLinkFloatingPointPrintf which would we could point users seeing "<no float>" to? No perceived regression, just an easy to communicate convenience feature added?
