And much more prone to multiplication. Take MIPS, for example. We only need one cross-compiler to build MIPS kernels, since you can switch the compiler between variants of BE/LE, 32/64 and suchlike. Take FRV as another example: you only need the one compiler to build both MMU and NOMMU kernels. However, each combination of variants (eg: MIPS-32BE) requires a separate userspace libraries, headers, etc. David -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
