What about ECOFF and XCOFF? (Tru64 ?? AIX ??) And I'd assume PE/COFF still uses most of the same COFF sources too. (Or did you only meant COFF debug info? Dunno, it has vaguely worse support for C++ by default, so perhaps that's why.) But yeah, GCC and BinUtils seem to focus mostly on ELF these days (see Gold linker). It seems that two of those platforms (AIX, Windows) are second-tier for upcoming GCC 4.7. No surprise about missing Tru64 (third-tier?) there if it's unsupported (sadly), but even the build status reports success for it for 4.6.x, so that's good. In other words, COFF still exists, just off to the side a bit. And to be more explicit, even popular targets like Mac OS X (i686-apple-darwin) and Windows (i686-pc- cygwin, i686-mingw32) are second-tier (though I don't know if that's philosophical or maybe because they don't use ELF or ...). So it should be obvious that GNU has other platforms (e.g. Linux is used on 4 of 7 first-tier targets) as a bigger priority. http://gcc.gnu.org/gcc-4.7/criteria.html http://gcc.gnu.org/gcc-4.6/buildstat.html
