2015-03-24[AArch64] Refactor generation of 835769 workaround stubs.Marcus Shawcroft2-104/+41
This patch recognizes that we only need to perform one scan for the 835769 errata and that this scan can take place before we insert branch stubs. The erratum scan code is relocated and adjusted to create stub entries directly rather than populating an intermediate representation. Since stub entries are created immediately we can drop the adhoc stub size adjustment code and allow the generic stub sizing code to deal with 835769 stub entries. This patch restructures the code but does not change the workaround used to deal with erratum 83679, the exact placement of workaround stubs in the final image may change slightly after this patch due to stubs being created in a different order.
2015-03-24[AArch64] Use _bfd_aarch64_add_stub_entry_in_group.Marcus Shawcroft2-15/+10
Adjust the 835769 workaround code to use _bfd_aarch64_add_stub_entry_in_group rather than inspect the underlying section_group structure directly.

2015-03-14S/390: Disable relocation sort against code sections.Andreas Krebbel4-0/+21
When downgrading from GD to IE model we rewrite the call to __tls_get_offset to a 64 bit load instruction. This relies on the fact that the additional relocation for the call target has already been executed when doing the rewrite. f1018: e3 20 d0 00 00 04 lg %r2,0(%r13) f101e: c0 e5 00 00 00 00 brasl %r14,f101e <__res_init+0x1e> f101e: R_390_TLS_GDCALL __libc_resp f1020: R_390_PLT32DBL __tls_get_offset+0x2 0000000f1020 39f6c00000014 R_390_PLT32DBL 0000000000000000 __tls_get_offset + 2 0000000f101e 3afb700000026 R_390_TLS_GDCALL 0000000000000008 __libc_resp + 0 Due to the reloc sorting the order changed an the PLT32DBL reloc is executed after the rewrite and overwrites part of the load instruction with garbage. bfd/ 2015-03-14 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * elf-s390-common.c (elf_s390_elf_sort_relocs_p): Don't sort relocs against code sections. * elf32-s390.c: Define elf_backend_sort_relocs_p. * elf64-s390.c: Likewise.
