ysionneaushorne: hi :) Is there a documentation of openrisc relocs somewhere ?10:45
ysionneau(regarding uclibc thread)10:45
ZipCPUysionneau: Please stick around.  The channel is active, but only slowly so.  (Answers might take 12hrs or so)10:46
ysionneauZipCPU: thx I'll stick around, though in a few hours I'll be hiking around in Scotland for 2 weeks10:46
ysionneauso I guess I'll read the answer after that10:46
ZipCPUThere are logs too, in case you have to drop out10:46
ysionneauright, thanks, I use a bouncer so I guess that wont be necessary10:48
ZipCPUshorne has been the one answering questions, so I'll tag him now in case that helps10:48
ZipCPU(I don't actually know the answer ...)10:48
ysionneauhe just answered about this topic on the uclibc-ng mailing list today10:49
ysionneauanyway there is no urgency whatsoever10:49
ysionneauok I've got my answer, it is there:
ysionneauthat only describes the dynamic relocs though, not the static ones10:52
ysionneau(the ones that are present in .o but not in final linked elf)10:52
shorneysionneau: there is not much on openrisc relocs other than what is in binutils source16:45
shornenote, I was able to reproduce the issue with the uclibc build16:46
shorneAnd I could fix it by just deleting the code that uss __syscall_error in or1k_clone.S16:46
shornethe problem is only in there16:46
shornei.e. I did this patch16:46

shorneSo, the bad relocation is only in this 1 file.  I think i/we will need to fix that16:48
shorneNote, in the glibc port I am working on fixing up I dont get this issue and the code is the same pretty much:
