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.

2015-03-04S390: Place "s390:31-bit" after default arch in 64-bit arch listAndreas Arnez2-37/+33
On 64-bit platforms GDB did not include "s390:31-bit" in its list of architecture names. This patch fixes that. To determine the list of architecture names for S390, gdbarch_printable_names() walks through the linked list of BFD arches starting with the default S390 arch, which is "s390:64-bit" on 64-bit platforms. But since "s390:64-bit" was at the end of that list, the 31-bit architecture was not reached. The patch swaps the elements of that list on 64-bit platforms. bfd/ChangeLog: * cpu-s390.c (N): New macro. (bfd_s390_31_arch): New. Define only if default target word size is 64 bits. Otherwise define... (bfd_390_64_arch): ...this. Make static. (bfd_s390_arch): Define according to the default target word size. Let the 'next' field point to the alternate arch.

I was looking at a current glibc using objdump today and saw an odd plt call stub. 0000000000044d80 <00000033.plt_call.__strchrnul>: 44d80: f8 41 00 28 std r2,40(r1) 44d84: e9 82 8c f8 ld r12,-29448(r2) 44d88: 7d 89 03 a6 mtctr r12 44d8c: e8 42 8d 00 ld r2,-29440(r2) 44d90: 28 22 00 00 cmpldi r2,0 44d94: 4c e2 04 20 bnectr+ 44d98: 48 13 84 f0 b 17d288 <realloc@plt> What? It doesn't branch to __strchrnul@plt on finding a zero r2? Turns out this isn't a real problem since the stub is for loading an ifunc, so will not be lazily resolved and thus r2 will never be zero. Of course, that means the thread-safety check is unnecessary. I also tweak the special __tls_get_addr_opt call stub here, to restore r2 immediately after the call. Not doing that might affect eh_frame unwinding. * elf64-ppc.c (plt_stub_size, build_plt_stub): Don't build thread-safe stubs for iplt. (build_tls_get_addr_stub): Restore r2 immediately after call.
