I pulled some files from a slightly more modern version of binutils from a Cavium SDK than ours and reduced differences to make the relevant parts of code match the older binutils API we provide, while still providing the newer opcode interface and a couple of nearby things. >> Is there specific functionality you need in GCC? > > Netlogic has some updates for GCC and binutils in its SDK.

If Netlogic can GPLv2 their specific changes or reimplement them relative to FreeBSD's toolchain, I think we would want to coordinate to get them into the tree. Our goal is generally to produce a fully-working self-hosting system out of the box. That may change at some point, especially if Warner's work on supporting external toolchains better pans out well, but I think for now it's a reasonable goal. Note that my understanding is that David O'Brien is working on bringing in the last GPLv2 binutils which will make the differences required for mips64r2 and Octeon substantially-smaller and I would hope for Netlogic processors as well. Thanks, Juli.
