[Bug ld/17592] x86-64 linker generates wrong PLT for large model
https://sourceware.org/bugzilla/show_bug.cgi?id=17592 Michael Matz matz at suse dot de changed: What|Removed |Added CC||matz at suse dot de --- Comment #1 from Michael Matz matz at suse dot de --- Back in http://www.sourceware.org/ml/binutils/2006-03/msg00276.html I suggested to place .plt after .text so that PLT and GOT are nearer to each other. In that case the large PLT layout would only need to be used if there were more that 100 million PLT slots (and GOT entry). Nevertheless, for full large model support you're right, the large PLT layout needs to be implemented. -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils

[Bug ld/17592] x86-64 linker generates wrong PLT for large model
https://sourceware.org/bugzilla/show_bug.cgi?id=17592 --- Comment #2 from H.J. Lu hjl.tools at gmail dot com --- (In reply to Michael Matz from comment #1) Back in http://www.sourceware.org/ml/binutils/2006-03/msg00276.html I suggested to place .plt after .text so that PLT and GOT are nearer to each other. In that case the large PLT layout would only need to be used if there were more that 100 million PLT slots (and GOT entry). It is an interesting idea. If we place .plt just after .text, there may be readonly sections before .got, the distance between .plt and .got.plt can still be big. If we place .plt just before .got, the text segment will have text, readonly data and followed by text. Do we want to do that? -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils

[Bug ld/17590] Order of multiple defsym commands irrelevant
https://sourceware.org/bugzilla/show_bug.cgi?id=17590 Alan Modra amodra at gmail dot com changed: What|Removed |Added Status|NEW |RESOLVED CC||amodra at gmail dot com Resolution|--- |WONTFIX --- Comment #2 from Alan Modra amodra at gmail dot com --- What you're missing is that the linking process makes multiple passes over the linker script, and --defsym is effectively a tiny addition to the linker script. On the first pass you will get _three = _one and _one = _two. The next pass sets _threee to the new value of _one, ie _two. -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
Re: Duplicate FDEs in .eh_frame

I'm seeing this with gcc 4.8.3 + binutils 2.24 on Haiku, and thought I'd see if this is intentional before I try to come up with a reduced testcase on another platform, as I don't believe all of our patches have been upstreamed at this point. The FDEs in question have the exact same lowpc/highpc, CIE and call frame instructions, the only discernable difference is that they're located in completely different parts of the section. The cases I've seen involved C++ and ld -r. Binutils git master and binutils-2_25-branch should have the problem fixed.
