* Properly place the NULL STT_FILE symbolusers/hjl/pr17975H.J. Lu2015-02-1519-75/+70

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In C, we can forward declare static structure instances. That doesn't work in C++ though. C++ treats these as definitions. So then the compiler complains about symbol redefinition, like: src/gdb/elfread.c:1569:29: error: redefinition of ‘const sym_fns elf_sym_fns_lazy_psyms’ src/gdb/elfread.c:53:29: error: ‘const sym_fns elf_sym_fns_lazy_psyms’ previously declared here The intent of static here is naturally to avoid making these objects visible outside the compilation unit. The equivalent in C++ would be to instead define the objects in the anonymous namespace. But given that it's desirable to leave the codebase compiling as both C and C++ for a while, this just makes the objects extern. (base_breakpoint_ops is already declared in breakpoint.h, so we can just remove the forward declare from breakpoint.c) gdb/ChangeLog: 2015-02-11 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> * breakpoint.c (base_breakpoint_ops): Delete. * dwarf2loc.c (dwarf_expr_ctx_funcs): Make extern. * elfread.c (elf_sym_fns_gdb_index, elf_sym_fns_lazy_psyms): Make extern. * guile/guile.c (guile_extension_script_ops, guile_extension_ops): Make extern. * ppcnbsd-tdep.c (ppcnbsd2_sigtramp): Make extern. * python/py-arch.c (arch_object_type): Make extern. * python/py-block.c (block_syms_iterator_object_type): Make extern. * python/py-bpevent.c (breakpoint_event_object_type): Make extern. * python/py-cmd.c (cmdpy_object_type): Make extern. * python/py-continueevent.c (continue_event_object_type) * python/py-event.h (GDBPY_NEW_EVENT_TYPE): Remove 'qual' parameter.

* Wrap BFD headers in extern "C"Pedro Alves2015-02-1111-0/+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".
* Fix adjust_pc_after_break, remove still current thread checkPedro Alves2015-02-115-2/+155
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On decr_pc_after_break targets, GDB adjusts the PC incorrectly if a background single-step stops somewhere where PC-$decr_pc has a breakpoint, and the thread that finishes the step is not the current thread, like: ADDR1 nop <-- breakpoint here ADDR2 jmp PC IOW, say thread A is stepping ADDR2's line in the background (an infinite loop), and the user switches focus to thread B. GDB's adjust_pc_after_break logic confuses the single-step stop of thread A for a hit of the breakpoint at ADDR1, and thus adjusts thread A's PC to point at ADDR1 when it should not, and reports a breakpoint hit, when thread A did not execute the instruction at ADDR1 at all. The test added by this patch exercises exactly that. I can't find any reason we'd need the "thread to be examined is still the current thread" condition in adjust_pc_after_break, at least nowadays; it might have made sense in the past. Best just remove it, and rely on currently_stepping(). Here's the test's log of a run with an unpatched GDB: 35 while (1); (gdb) PASS: gdb.threads/step-bg-decr-pc-switch-thread.exp: next over nop next& (gdb) PASS: gdb.threads/step-bg-decr-pc-switch-thread.exp: next& over inf loop thread 1 [Switching to thread 1 (Thread 0x7ffff7fc2740 (LWP 29027))](running) (gdb) PASS: gdb.threads/step-bg-decr-pc-switch-thread.exp: switch to main thread Breakpoint 2, thread_function (arg=0x0) at ...src/gdb/testsuite/gdb.threads/step-bg-decr-pc-switch-thread.c:34 34 NOP; /* set breakpoint here */ FAIL: gdb.threads/step-bg-decr-pc-switch-thread.exp: no output while stepping gdb/ChangeLog: 2015-02-11 Pedro Alves <pedro@codesourcery.com> * infrun.c (adjust_pc_after_break): Don't adjust the PC just because the event thread is not the current thread. gdb/testsuite/ChangeLog: 2015-02-11 Pedro Alves <pedro@codesourcery.com> * gdb.threads/step-bg-decr-pc-switch-thread.c: New file. * gdb.threads/step-bg-decr-pc-switch-thread.exp: New file.
