Getting rid of generic *-*-aout* and *-*-coff*, where there are corresponding ELF targets for the same CPU, is what I was suggesting might be considered (and has not attracted any comments on the general idea). This is not the same as getting rid of COFF and a.out altogether, because of various other targets using those formats. It is of course the case that various features in GCC work better with ELF and DWARF than other formats (and LTO is being written to use libelf at present, for example, although I imagine it may be extended to support other file formats with the same raw data embedded in them in due course). -- Joseph S.
