The very first time this function is ever called its MINSIZE parameter is always 0 and the global LINE_SIZE is 1024. Prior to the above mentioned commits we spot that the line_state variables have not yet been initialised, and allocate them some new buffer, then we enter this loop: for (n = minsize; n < line_size; n++) { visible_line[n] = 0; invisible_line[n] = 1; } which would initialise everything from the incoming minimum up to the potentially extended upper line size. The problem is that the above patches added a new condition that would bump up the minsize like this: if (minsize <= _rl_screenwidth) /* XXX - for gdb */ minsize = _rl_screenwidth + 1; So, the first time this function is called the incoming MINSIZE is 0, the LINE_SIZE global is 1024, and if the _rl_screenwidth is 80, we see that MINSIZE will be pushed up to 80. We still notice that the line state is uninitialised and allocate some buffers, then we enter the initialisation loop: for (n = minsize; n < line_size; n++) { visible_line[n] = 0; invisible_line[n] = 1; } And initialise from 80 to 1023 i the newly allocated buffers, leaving 0 to 79 uninitialised. To confirm this is an issue, if we then look at rl_redisplay we see that a call to init_line_structures is followed first by a call to rl_on_new_line, which does initialise visible_line[0], but not invisible_line[0]. Later in rl_redisplay we have this logic: if (visible_line[0] != invisible_line[0]) rl_display_fixed = 0; The use of invisible_line[0] here will be undefined. Considering how this variable was originally initialised before the above patches, this patch modifies the initialisation loop in init_line_structures, to use the original value of MINSIZE. With this change the valgrind warning goes away. readline/ChangeLog: PR cli/24980 * display.c (init_line_structures): Initialise line_state using original minsize value.

2019-09-23PowerPC64 dynamic symbol tweaksAlan Modra2-33/+45
In check_relocs, bfd_link_pic true means ld is producing a shared library or a position independent executable. !bfd_link_pic means a fixed position (ie. static) executable since the relocatable linking case is excluded. So it is appropriate to continue using bfd_link_pic when testing whether non-pcrelative relocations should be dynamic, and !bfd_link_pic for the special case of ifunc in static executables. However, -Bsymbolic shouldn't affect PIEs (they are executables so none of their symbols should be overridden) and PIEs can support copy relocations, thus bfd_link_executable should be used in those cases rather than bfd_link_pic. I've also removed the test of ELIMINATE_COPY_RELOCS in check_relocs. We can sort out what to do regarding copy relocs later, which allows the code in check_relocs to be simplified. * elf64-ppc.c (ppc64_elf_check_relocs): Use bfd_link_executable in choosing between different actions for shared library and non-shared library cases. Delete ELIMINATE_COPY_RELOCS test. (dec_dynrel_count): Likewise. Account for ifunc special case. (ppc64_elf_adjust_dynamic_symbol): Copy relocs are for executables, not non-pic.

2019-09-20Remove Cell Broadband Engine debugging supportUlrich Weigand108-11285/+189
This patch implements removal of Cell/B.E. support, including - Support for the spu-*-* target - Support for native stand-alone SPU debugging - Support for integrated debugging of combined PPU/SPU applications - Remote debugging (gdbserver) support for all the above. The patch also removes the TARGET_OBJECT_SPU target object type, as this is available only on Cell/B.E. targets, including - Native Linux support - Core file support (including core file generation) - Remote target support, including removal of the qXfer:spu:read and qXfer:spu:write remote protocal packets and associated support in gdbserver. gdb/ChangeLog 2019-09-20 Ulrich Weigand <uweigand@de.ibm.com> * NEWS: Mention that Cell/B.E. debugging support was removed. * MAINTAINERS: Remove spu target. * config/djgpp/fnchange.lst: Remove entries for removed files. * Makefile.in (ALL_TARGET_OBS): Remove solib-spu.o, spu-multiarch.o, and spu-tdep.o.

2019-09-20Change TUI window commands to be case-sensitiveTom Tromey4-95/+77
The TUI window-related commands like "focus" are case insensitive. This is not the norm in gdb, and I don't see a good reason to have it here. This patch changes the TUI to be case sensitive, like the rest of gdb. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * NEWS: Mention case-sensitivity of TUI commands. * tui/tui-win.c (tui_set_focus_command): Now case-sensitive. (tui_set_win_height_command, parse_scrolling_args): Likewise. * tui/tui-layout.c (tui_layout_command): Now case-sensitive.
2019-09-20Use make_unique_xstrdup in TUITom Tromey3-2/+9
This changes a couple of spots in the TUI to use make_unique_xstrdup. This simplifies the code slightly. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-source.c (tui_source_window::set_contents): Use make_unique_xstrdup. * tui/tui-disasm.c (tui_disasm_window::set_contents): Use make_unique_xstrdup.
2019-09-20Remove separator comments from TUITom Tromey5-55/+7
This removes various separator comments from the TUI. These aren't used elsewhere in gdb, and they were incorrect in some cases as well. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-data.c: Remove separator comments. * tui/tui-layout.c: Remove separator comments. * tui/tui-win.c: Remove separator comments. * tui/tui-wingeneral.c: Remove separator comments.
2019-09-20Remove strcat_to_bufTom Tromey3-15/+5
An earlier patch in the series removed the last call to strcat_to_buf, so this patch removes the function entirely. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui.h (strcat_to_buf): Don't declare. * tui/tui.c (strcat_to_buf): Remove.
