Why -fno-asm? Half the point of using gcc for me is to be able to use inline asm, rather than the bizarre .il stuff Sun's CC forces on you. > If it's Sun's cc, then different options apply.

For Sun's CC, there are 2 flavors of flags required: "old": -xarch=amd64 -Di86pc -Wu,-xmodel=kernel "new": -m64 -xarch=sse2a -Di86pc -xmodel=kernel Where "old" means versions < 5.9 Drew _______________________________________________ networking-discuss mailing list [email protected]
