Re: Need help on reducing linker issue
Hi Alan, this linker version is part of a 3rd party development suite, so for myself it's not easy to only update the linker. Can you remember if there was some kind of reproduction scenario at that time? greetings, Roger 2010/11/22 Alan Modra amo...@gmail.com On Mon, Nov 22, 2010 at 02:34:29PM +0100, Roger Jeurninck wrote: the version which we use is 2.17.

For x86, datarel offsets are supposed to be relative to .got.plt rather than .got. On ia64, datarel is relative to __gp. Do you have an idea where this is specified? I've only found Table 11.6 in the LSB 4.0.0: http://refspecs.freestandards.org/LSB_4.0.0/LSB-Core-generic/LSB-Core-generic/dwarfext.html which says DW_EH_PE_datarel0x30Value is relative to the beginning of the .got or .eh_frame_hdr section. A spec which says `do A or B' with no indication when to do one or the other seems like a joke to me. I've looked into the architecture extensions for advise, but found nothing. I ran into this when trying to get the libgcc unwinder to work with dl_iterate_phdr on Solaris 11. While the function works, Sun ld interpreted DW_EH_PE_datarel relative to .eh_frame_hdr on i386 (apart from other problems). It would be good to have a spec to point to for this, rather than saying `GCC has been doing this' instead. Thanks.

A datarel value is relative to this base address. Except to muddy the waters further, DW_EH_PE_datarel when used in .eh_frame_hdr takes its base to be the address of the .eh_frame_hdr section! -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils

We have a documented use case that, ELF side, works exactly as intended, and a software that tries to use the documented syntax but fails. We also have Chrom(e|ium)OS going toward a hack (creating an UNVERSIONED version to attach to those symbols) just to be able to compile it. From my point of view, the right choice on the link editor side is to emit the correct ELF file (rather than stop on a corner case), and then report/track down the issue on ld.so side to ensure that it links as intended. This avoids having nasty hacks in place for fuse, and behaves as the documentation says it should. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils
