S/390: Disable relocation sort against code sections. When downgrading from GD to IE model we rewrite the call to __tls_get_offset to a 64 bit load instruction.

S390: Place "s390:31-bit" after default arch in 64-bit arch list 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.

PowerPC64 thread-safe stubs not needed for iplt 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.

S390: Support new vector register sections The IBM z13 has new 128-bit wide vector registers v0-v31, where v0-v15 include the existing 64-bit wide floating point registers. The Linux kernel presents the vector registers as two additional register sets, one for the right halves of v0-v15 and another one for the full registers v16-v31.

Properly place the NULL STT_FILE symbol revistited I was having a little closer look at what is going on here and noticed that HJ unconditionally emits a NULL STT_FILE symbol before emitting forced local symbols. That means we really don't need a second pass over forced local symbols. The only reason for two passes is when some forced local symbol can be emitted before the NULL STT_FILE. So I set about removing the second pass, updating the testsuite all over again. It's also unnecessary to emit the NULL STT_FILE when no previous file symbol has been emitted. bfd/ PR ld/17975 * elflink.c (struct elf_outext_info): Remove need_second_pass and second_pass.

PR ld/17973 LTO file syms LTO output objects have an STT_FILE symbol using the name of the file, a temporary file. This results in executables that can't be exactly reproduced, so the file name needs to be dropped. We don't want to lose all file symbols when linking a mix of lto and non-lto objects as a file symbol can be used to figure which source file generated a given local symbol. So lto output objects need to be marked. I chose to mark lto output objects with a new bfd flag. This flag is also used to fix a bug in the link-once handling; An object being loaded after "loading_lto_outputs" is set might be one extracted from an archive to satisfy new references from lto objects, not an lto object itself. The new flag is copied from archive to elements, and the same done for no_export. This fixes a bug in that --exclude-libs doesn't work with thin archives. I'm not completely happy with this part of the patch and may revist this to avoid the hack in _bfd_look_for_bfd_in_cache.

Correct PowerPC64 local-dynamic TLS linker optimization The linker hardcoded r3 into a local-dynamic to local-exec TLS optimization sequence. This is normally the case since r3 is required as a parameter to (the optimized out) __tls_get_addr call. However, it is possible for a compiler, LLVM in this case, to set up the parameter value in another register then copy it to r3 before the call. When fixing this problem, I noticed that ppc32 had another bug when optimizing away one of the TLS insns to a nop. The patch also tidies a mask used by global-dynamic to initial-exec TLS optimization, to just select the fields needed. Leaving the offset in the instruction wasn't a bug since it will be overwritten anyway. bfd/ * elf64-ppc.c (ppc64_elf_relocate_section): Correct GOT_TLSLD optimization.

PowerPC64 changes for xlc The changes to reorder sections for better relro protection on powerpc64, 3e2b0f31, 23283c1b, and 5ad18f16, run into a problem with xlc. xlc -qdatalocal puts global variables into .toc, which means that .toc must be writable.

Fallout from recent bfd_reloc_outofrange changes Commit ec93045b and cd21f5da introduced a large number of tic4x and tic54x regressions, due to the new checks being wrong for targets with octets_per_byte != 1. To fix that I introduced a new bfd_get_section_limit_octets and performed the check on octets rather than byte adresses, reducing the number of bfd_octets_per_byte calls. bfd_octets_per_byte is rather expensive.. I then wondered why the same bfd_reloc_outofrange check added to bfd_perform_relocation wasn't also added to bfd_install_relocation. The two functions are virtually identical and ought to remain that way. However, adding the same check to bfd_install_relocation resulted in ld-elf "FAIL Link eh-group.o to eh-group" on many ELF targets, including x64_64-linux. The reason being that eh-group.o has NONE relocs at the end of a section, and most targets give NONE relocs a non-zero size. So if we are to keep the new outofrange check it appears that NONE relocs must have a zero size. * bfd-in.h (bfd_get_section_limit_octets): New define, extracted from..
