2015-02-26PowerPC64 thread-safe stubs not needed for ipltAlan Modra2-6/+17
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.

Adds support to the assembler to write out data for tracking the use of .org and .align directives. This data is collected within the assembler and written out to a section ".avr.prop" (if there's anything to write out). This patch does not add any tests. The next patch in this series will add a better mechanism for visualising the contents of .avr.prop which will make writing tests much easier. This patch also does not make any use of this collected data, that will also come along in a later patch; the intended consumer is the linker, during linker relaxation this information will be used to ensure that the .org and .align directives are honoured. bfd/ChangeLog: * elf32-avr.h (AVR_PROPERTY_RECORD_SECTION_NAME): Define.

2015-02-20S390: Support new vector register sectionsAndreas Arnez3-0/+70
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.

2015-02-18Properly place the NULL STT_FILE symbol revistitedAlan Modra4-41/+45
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.

2015-02-14PR ld/17973 LTO file symsAlan Modra7-40/+87
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.

2015-02-11Merge linker plugin handling into BFD plugin supportH.J. Lu4-7/+87
Linker plugin_maybe_claim is the interface of linker plugin support. This patch extracts linker plugin_maybe_claim into plugin_object_p and makes it available to BFD via a new function: void register_ld_plugin_object_p (const bfd_target *(*) (bfd *)); bfd_plugin_object_p calls plugin_object_p registered by linker first. It adds an enum bfd_plugin_format field and a pointer to plugin dummy BFD so that plugin_object_p stores plugin dummy BFD to allow plugin_maybe_claim to retrieve it later. bfd/ PR ld/17878 * bfd.c (bfd_plugin_format): New.

2015-02-11Wrap BFD headers in extern "C"Pedro Alves11-0/+72
These were the BFD changes needed for building a C++ GDB with --enable-targets=all, on x86_64 Fedora 20. For libbfd.h and libcoff.h, this does same as already done when generating bfd.h: open extern "C" in the -in.h header, and close it from the Makefile. bfd/doc/ChangeLog: 2015-02-11 Pedro Alves <palves@redhat.com> * Makefile.am (libbfd.h, libcoff.h): Close extern "C" scope. * Makefile.in: Regenerate. bfd/ChangeLog: 2015-02-11 Pedro Alves <palves@redhat.com> * libbfd-in.h [__cplusplus]: Open extern "C" scope. * libcoff-in.h [__cplusplus]: Open extern "C" scope. * libbfd.h: Regenerate. * libcoff.h: Regenerate. * elf-bfd.h [__cplusplus]: Wrap in extern "C". * mach-o.h [__cplusplus]: Wrap in extern "C". * som.h [__cplusplus]: Wrap in extern "C".
