Fixes powerpc64le ld segfaults when --emit-relocs is used. ELFv2 needs fewer relocs to annotate plt call stubs. I correctly allocated a smaller buffer and wrote the proper relocs, but stupidly bumped the reloc count as for ELFv1. * elf64-ppc.c (ppc_build_one_stub): Correct reloc count passed to get_relocs for ELFv2.

Issue a linker error if TLS sections are not adjacent Bad linker script may lead to TLS sections separated by non-TLS sections in output.

* elf64-ppc.c (STK_LINKER): Comment typo fix.
Check incompatible existing default symbol definition After resolving a versioned reference, foo@VER1, to a default versioned definition, foo@@VER1, from a shared object, we also merge it with the existing regular default symbol definition, foo. When foo is IFUNC and foo@@VER1 aren't, we will merge 2 incompatible definitions. This patch avoids merging foo@@VER1 definition with foo definition if one is IFUNC and the other isn't.

Revert the last change It has been fixed by commit 4199e3b8669d0a36448687850374fdc2ad7240b6 Author: Alan Modra <amodra@gmail.com> Date: Wed Jan 15 21:50:55 2014 +1030 non-PIC references to __ehdr_start in pie and shared Rather than hacking every backend to not discard dynamic relocations against an undefined hidden __ehdr_start, make it appear to be defined early. We want __ehdr_start hidden before size_dynamic_sections so that it isn't put in .dynsym, but we do need the dynamic relocations for a PIE or shared library with a non-PIC reference. Defining it early is wrong if we don't actually define the symbol later to its proper value. (In some cases we want to leave the symbol undefined, for example, when the ELF header isn't loaded, and we don't have this infomation available in before_allocation.) * elf32-i386.c (elf_i386_allocate_dynrelocs): Revert the last change. * elf64-x86-64.c (elf_x86_64_allocate_dynrelocs): Likewise.

Adjust LOAD segment to generate GNU_RELRO segment This patch fixes 2 GNU_RELRO segment bugs: 1. lang_size_sections didn't properly align base to the maximum alignment power of sections between DATA_SEGMENT_ALIGN and DATA_SEGMENT_RELRO_END. 2. ld failed to adjust LOAD segment to generate GNU_RELRO segment when LOAD segment doesn't fit GNU_RELRO segment. This is https://sourceware.org/bugzilla/show_bug.cgi?id=14207 We "fixed" ld by not generating GNU_RELRO segment. This patch adjusts LOAD segment to generate GNU_RELRO segment.
