SDCC for the 8051 only works with the assembler and linker that come with it, sorry. It needs a separate assembler and linker and AFAIK there is no other free/open source option available. > I just learned that the SiLabs > environment (IDE) without which it's apparently a pain to use their MCU's, > relies upon OMF files produced by SDCC tools, among others.

But the assembler/linker combination can also output OMF files without being called by SDCC. And thus the SiLabs IDE can download and debug the output. The SiLabs IDE can download only HEX- files (which have no debug information) and OMF-files (which do). If your favourite assembler (with or without linker) can generate OMF files, the IDE should be able to load and debug them. The only real issue I can think of would be the endianness for displaying multibyte variables. Both big-endian and little-endian are supported so choose a compiler setting with compatible endianness.
