The PT_DYNAMIC segment was being hard coded to have read, write, and execute permission regardless of the underlying PT_LOAD segment permissions. Deleting this code allows the default linker behavior which is to set the dynamic segment to the same permissions as the sections that make it up. This change alters one existing test case to check the segment flags for PT_DYNAMIC. bfd/ChangeLog * elfxx-mips.c(_bfd_mips_elf_modify_segment_map): Deleted hard coding of PT_DYNAMIC segment flags. ld/testsuite/ChangeLog * ld-mips-elf/pic-and-nonpic-3a.sd: Check DYNAMIC segment flags.

Fix bad interaction between --relax and tls optimisation Adding long-branch stubs for __tls_get_addr calls that are optimised away is silly. It also causes assertion failures on newer object files that use R_PPC_TLSGD and R_PPC_TLSLD marker relocs, and half-optimised (ie. broken) code for older object files.

powerpc relax_section and section contents cache This patch provides a means for backend relax_section support to increase the size of a section without needing to reallocate section contents. This helps reduce memory usage when the added space does not need to be written in relax_section, as is the case for powerpc. Writing the stubs later means a few tweaks are needed in the powerpc relocate_section function, but also removes some code duplication since the extra ld -r relocs can be written there too. * elf-bfd.h (struct elf_backend_data): Add caches_rawsize. * elfxx-target.h (elf_backend_caches_rawsize): Define.

ppc476 icache bug workaround This implements a work-around for an icache bug on 476 that can cause execution of stale instructions when control falls through from one page to the next.

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.
