Hello whomever you are, The code is bigger because SDCC is made by a few hobbyists, not by trained professionals who can spend all day working on it.
The iram-size is 256 bytes on the DS89C430. So remove the option and keep the default. The ram-size is 1kB but if you don't want to use / initialize it use --no-xinit- opt. Intel hex files (.ihx) do not contain debugging information. For that you need to use the .cdb file or the OMF file without extension. Not only is function inlining not supported, it even generates errors as can be seen in this bug report: http://sourceforge.net/tracker/index.php?func=detail&aid=1478649&group_i d=599&atid=100599 But function inlining is not in general good for optimized size, it's mostly good for speed. > Hi list.
