Isn't that what multilib is for? On a related note, I wish GCC had a "no-float" option that could be used in place of soft-float. It would be ABI-compatible with either soft or hard float, because it doesn't use float at all (GCC would raise an error if you try). > last i looked, some of the math functions in arm's libgcc depended on C > library functions (like raise() and abort()). this is the kind of stuff Jean > is trying to avoid. It seems pretty reasonable for U-Boot to provide functions like raise()/abort() that take the place of a hardware exception, and display an error message. -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
