If linux insists on not using libgcc, See e.g: "http://www.ussg.iu.edu/hypermail/linux/kernel/0009.2/0655.html"; for a rationale behind that. > it should provide: > > > After your change Linux has unresolved references to external __ashldi3(), > > __ashrdi3() and __lshrdi3() functions at the final link. > > ...these functions itself. Well, other targets, like the i386 (which didn't even have a 64-bit variation till recently), do not force Linux to go through such contortions. I can't see a reason why MIPS should be different -- it's not any harder to implement shifts for this processor than for an average other platform. Anyway, the patch works for me and it has been published so that others can use it, thus I have no incentive to do anything else, sorry. Maciej
