File aarch64-dynamic-placement.patch of Package cross-sparc-binutils
2013-07-02 Marcus Shawcroft <marcus.shawcroft@arm.com> * elf64-aarch64.c (aarch64_elf_create_got_section): New. (elf64_aarch64_check_relocs): Use aarch64_elf_create_got_section. (elf64_aarch64_create_dynamic_sections): Do not define _GLOBAL_OFFSET_TABLE_; call aarch64_elf_create_got_section. ld/testsuite/ * ld-aarch64/gc-plt-relocs.d: Adjust expected .got offsets. * ld-aarch64/tls-desc-ie.d: Likewise. * ld-aarch64/emit-relocs-311.d: Adjust expected symbol. * ld-aarch64/tls-relax-all.d: Likewise. * ld-aarch64/tls-relax-gd-ie.d: Likewise. * ld-aarch64/tls-relax-gdesc-ie.d: Likewise. * ld-aarch64/tls-relax-gdesc-ie-2.d: Likewise. 2013-07-02 Marcus Shawcroft <marcus.shawcroft@arm.com> * ld-aarch64/emit-relocs-309-low.d: Adjust .text address. * ld-aarch64/emit-relocs-309-up.d: Adjust .got address. * ld-aarch64/emit-relocs-312.d: Adjust offsets into .got. * ld-aarch64/tls-relax-all.d: Likewise. * ld-aarch64/gc-got-relocs.d: Adjust expected .got content. * ld-aarch64/gc-tls-relocs.d: Likewise. * ld-aarch64/tls-relax-gd-ie.d: Likewise. * ld-aarch64/tls-relax-gdesc-ie-2.d: Likewise. * ld-aarch64/tls-relax-gdesc-ie.d: Likewise. 2013-06-27 Marcus Shawcroft <marcus.shawcroft@arm.com> * elf64-aarch64.c (elf64_aarch64_check_relocs): Reserve one slot in sgot. (elf64_aarch64_finish_dynamic_sections): Place the &_DYNAMIC reference in sgot[0] rather than sgotplt[0].
