Patrick Palka	c4ef48c6b2	Asynchronously resize the TUI This patch teaches the TUI to resize itself asynchronously instead of synchronously. Asynchronously resizing the screen when the underlying terminal gets resized is the more intuitive behavior and is surprisingly simple to implement thanks to GDB's async infrastructure. The implementation is straightforward. TUI's SIGWINCH handler is just tweaked to asynchronously invoke a new callback, tui_async_resize_screen, which is responsible for safely resizing the screen. Care must be taken to not to attempt to asynchronously resize the screen while the TUI is not active. When the TUI is not active, the callback will do nothing, but the screen will yet be resized in the next call to tui_enable() by virtue of win_resized being TRUE. (So, after the patch there are still two places where the screen gets resized: one in tui_enable() and the other now in tui_async_resize_screen() as opposed to being in tui_handle_resize_during_io(). The one in tui_enable() is still necessary to handle the case where the terminal gets resized inside the CLI: in that case, the TUI still needs resizing, but it must wait until the TUI gets re-enabled.) gdb/ChangeLog: * tui/tui-io.c (tui_handle_resize_during_io): Remove this function.

Jose E. Marchesi	f6a88844c3	Factorize target program transformations in the GDB_AC_TRANSFORM macro. This patch introduces a new M4 macro GDB_AC_TRANSFORM to avoid repeating the common idiom which is the transformation of target program names, i.e. from gdb to sparc64-linux-gnu-gdb. It also makes gdb/configure.ac and gdb/testsuite/configure.ac to use the new macro. gdb/ChangeLog: 2015-02-18 Jose E.

Jose E. Marchesi	9aca2ff83e	New commands `enable probe' and `disable probe'. This patch adds the above-mentioned commands to the generic probe abstraction implemented in probe.[ch]. The effects associated to enabling or disabling a probe depend on the type of probe being handled, and is triggered by invoking two back-end hooks in `probe_ops'. In case some particular probe type does not support the notion of enabling and/or disabling, the corresponding fields on `probe_ops' can be initialized to NULL. This is the case of SystemTap probes. gdb/ChangeLog: 2015-02-17 Jose E.

Jose E. Marchesi	03e98035a2	Move `compute_probe_arg' and `compile_probe_arg' to probe.c This patch moves the `compute_probe_arg' and `compile_probe_arg' functions from stap-probe.c to probe.c. The rationale is that it is reasonable to assume that all backends will provide the `$_probe_argN' convenience variables, and that the user must be placed on the PC of the probe when requesting that information. The value and type of the argument can still be determined by the probe backend via the `pops->evaluate_probe_argument' and `pops->compile_to_ax' handlers. Note that a test in gdb.base/stap-probe.exp had to be adjusted because the "No SystemTap probe at PC" messages are now "No probe at PC". gdb/ChangeLog: 2015-02-17 Jose E. Marchesi <jose.marchesi@oracle.com> * probe.c (compute_probe_arg): Moved from stap-probe.c (compile_probe_arg): Likewise.

Jose E. Marchesi	6f9b84910f	Adapt `info probes' to support printing probes of different types. A "probe type" (backend for the probe abstraction implemented in probe.[ch]) can extend the information printed by `info probes' by defining additional columns. This means that when `info probes' is used to print all the probes regardless of their types, some of the columns will be "not applicable" to some of the probes (like, say, the Semaphore column only makes sense for SystemTap probes). This patch makes `info probes' fill these slots with "n/a" marks (currently it breaks the table) and not include headers for which no actual probe has been found in the list of defined probes. This patch also adds support for a new generic column "Type", that displays the type of each probe. SystemTap probes identify themselves as "stap" probes. gdb/ChangeLog: 2015-02-17 Jose E. Marchesi <jose.marchesi@oracle.com> * probe.c (print_ui_out_not_applicables): New function. (exists_probe_with_pops): Likewise.

Also invoke `print_ui_out_not_applicables' in order to match the column rows with the header when probes of several types are listed. Print the "Type" column. * probe.h (probe_ops): Added a new probe operation `type_name'. * stap-probe.c (stap_probe_ops): Add `stap_type_name'. (stap_type_name): New function.	12 years ago
Alan Modra	2ec55de302	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.

Patrick Palka	69efdff130	Remove superfluous function key_is_command_char() The function key_is_command_char() is simply a predicate that determines whether the function tui_dispatch_ctrl_char() will do anything useful. Since tui_dispatch_ctrl_char() performs the same checks as key_is_command_char() it is unnecessary to keep key_is_command_char() around. This patch removes this useless function and instead unconditionally calls tui_dispatch_ctrl_char() inside its only caller, tui_getc(). gdb/ChangeLog: * tui/tui-io.c (tui_getc): Don't call key_is_command_char.

Pedro Alves	f8e5e23e3d	TUI: resize windows to new terminal size before displaying them If the user: #1 - disables the TUI #2 - resizes the terminal #3 - and then re-enables the TUI the next wgetch() returns KEY_RESIZE. This indicates to the ncurses client that ncurses detected that the terminal has been resized. We don't handle KEY_RESIZE anywhere, so it gets passed on to readline which interprets it as a multibyte character, and then the end result is that the first key press after enabling the TUI is misinterpreted. We shouldn't really need to handle KEY_RESIZE (and not all ncurses implementations have that). We have our own SIGWINCH handler, and, when we re-enable the TUI, we explicitly detect terminal resizes and resize all windows. The reason ncurses currently does detects a resize is that something within tui_enable forces a refresh/display of some window before we get to do the actual resizing. Setting a break on ncurses' 'resizeterm' function helps find the culprit(s): (top-gdb) bt #0 resizeterm (ToLines=28, ToCols=114) at ../../ncurses/base/resizeterm.c:462 #1 0x0000003b42812f3f in _nc_update_screensize (sp=0x2674730) at ../../ncurses/tinfo/lib_setup.c:443 #2 0x0000003b0821cbe0 in doupdate () at ../../ncurses/tty/tty_update.c:726 #3 0x0000003b08215539 in wrefresh (win=0x2a7bc00) at ../../ncurses/base/lib_refresh.c:65 #4 0x00000000005257cb in tui_refresh_win (win_info=0xd73d60 <_locator>) at /home/pedro/gdb/mygit/src/gdb/tui/tui-wingeneral.c:60 #5 0x000000000052265b in tui_show_locator_content () at /home/pedro/gdb/mygit/src/gdb/tui/tui-stack.c:269 #6 0x00000000005273a6 in tui_set_key_mode (mode=TUI_COMMAND_MODE) at /home/pedro/gdb/mygit/src/gdb/tui/tui.c:321 #7 0x00000000005278c7 in tui_enable () at /home/pedro/gdb/mygit/src/gdb/tui/tui.c:494 #8 0x0000000000527011 in tui_rl_switch_mode (notused1=1, notused2=1) at /home/pedro/gdb/mygit/src/gdb/tui/tui.c:108 That is, tui_enable calls tui_set_key_mode before we've resized all windows, and that refreshes a window as side effect.

Cary Coutant	e9c1bdad26	Fix --dynamic-list so that symbols not in the list are still exported. In PR 13577, the complaint was that -Bsymbolic was overriding the binding behavior for symbols listed in the --dynamic-list by setting the DT_SYMBOLIC tag in the dynamic table. In reading the Gnu ld manual, I decided that --dynamic-list should be mutually exclusive of -Bsymbolic, and modified gold so that --dynamic-list would treat symbols listed as preemptible, and all other symbols as internally bound. I was wrong. PR 16992 shows that with --dynamic-list (and not -Bsymbolic), a symbol not listed in the dynamic list is being internally bound within the shared library, but because it's still in the dynamic symbol table, we expose it to a COPY relocation, and things go really bad from there. (I can reproduce the same failure, simply by turning on -Bsymbolic-functions with the Gnu linker. Even though the symbol is bound internally, it's still exported to the dynamic symbol table, and is exposed to a COPY relocation.) I've backed out part of the fix for PR 13577, and -Bsymbolic (or -Bsymbolic-functions) can now be used with --dynamic-list, but if the two are used together, we do not set DT_SYMBOLIC or DF_SYMBOLIC (this matches Gnu ld behavior). We now treat symbols listed in the dynamic list as premptible, but we do not automatically treat symbols not listed there as non-premptible. gold/ PR gold/13577 PR gold/16992 * layout.cc (Layout::finish_dynamic_section): Don't set DT_SYMBOLIC or DF_SYMBOLIC if --dynamic-list option is used. * options.cc (General_options::finalize): --dynamic-list is not mutually exclusive with -Bsymbolic. * symtab.h (Symbol::is_preemptible): Don't exclude dynamic symbols not listed in --dynamic-list. * testsuite/Makefile.am (dynamic_list_lib2.so): Add -Bsymbolic-functions. * testsuite/Makefile.in: Regenerate.	12 years ago

Alan Modra	ce875075f9	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.
