You might not be aware, but we are since a while working on getting ia64 back into the Linux kernel and it is successfully maintained out of tree since nearly 3 mainline releases now. You can read up on our progress on [1] and [2] and after the release message for v6.9 on the LKML. [1]: https://lore.kernel.org/all/fe5f6e9b-02a2-42e9-8151-ae4b6fdba7e3@web.de/ [2]: https://lore.kernel.org/all/145da253-b3bc-43da-a262-a3ebdfbea5a2@web.de/ The HP Sim platform was also restored in the meantime, so people can test ia64 software on e.g. x86_64, up to mainline. See the Linux stable release (candidate) builds on [3] for example, all still maintained stable kernels work in Ski with HP Sim as platform. [3]: https://github.com/linux-ia64/linux-stable-rc/actions/runs/8995653713 Each mainline release (candidate) was/is also regularly cross-compiled with binutils 2.41/2.42 (since a while) and the latest gcc-14 (now gcc-15) snapshot since beginning of the year. The result was/is tested on the following real machines: * rx2620 (w/Montecito) * rx4640 (w/Madison) * rx2660 (w/Montecito) * rx6600 (w/Montvale) * rx2800 i2 (w/Tukwila) ...and of course also in Ski with the HP Sim platform. All that w/o any showstopping issues related to binutils or gcc. For the gcc cross-compiler LRA was also enabled recently, also w/o any negative effect on the resulting kernels. **** So is there something broken in binutils for ia64 that we don't know of maybe?
