Not sure which of those fixes were backported to gcc-5. Well, remember, I only went down with binutils / gcc versions because latest binutils/ld segfaults linking newer glibcs: https://twitter.com/renebln/status/984741114757439488 #2 in bfd_malloc at ../../bfd/libbfd.c:193 #3 in _bfd_elf_strtab_finalize at ../../bfd/elf-strtab.c:368 #4 in _bfd_elf_assign_file_positions_for_non_load at ../../bfd/elf.c:6318 #5 _bfd_elf_write_object_contents at ../../bfd/elf.c:6354 #6 in bfd_close at ../../bfd/… This is how I ended up downgrading binutils, glibc and gcc until I had a user-land that built, … (yes, I neglected t2/sparc* support the last years, sorry for that) > So, in case you are unable to track down the issue in the kernel, try a newer > toolchain and the latest version of binutils (2.30 + branch updates). Speaking of “updates”, if you have a patch for that segfault, … But today is your lucky, as my latest financing opensource work by YouTube videos (http://youtube.com/renerebe) shows some results, I now rebuild latest t2/svn:HEAD toolchain and re-build the Linux kernel for you (as the binutils/ld crash happened with glibc, I only need to toolchain for the kernel build): # scripts/Build-Target -cfg sparc64 -job 0-binutils == 13:34:33 =[0]=> Building develop/binutils [2.30 9.0-svn]. # scripts/Build-Target -cfg sparc64 -job 0-gcc == 13:36:00 =[0]=> Building develop/gcc [7.3.0 9.0-svn]. # scripts/Build-Target -cfg sparc64 -job 1-linux == 13:42:19 =[1]=> Building base/linux [4.16.3 9.0-svn]. Waiting for the kernel to finish on my more Epyc CPU and then rsync and reboot. So maybe less than an hour or so ;-) René -- ExactCODE GmbH, Lietzenburger Str. 42, DE-10789 Berlin http://exactcode.com | http://exactscan.com | http://ocrkit.com | http://t2-project.org | http://rene.rebe.de -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
