2019-09-24[gdb/tdep] Handle mxcsr kernel bug on Intel Skylake CPUsTom de Vries1-0/+6
On my openSUSE Leap 15.1 x86_64 Skylake system with the default (4.12) kernel, I run into: ... FAIL: gdb.base/gcore.exp: corefile restored all registers ... The problem is that there's a difference in the mxcsr register value before and after the gcore command: ... - mxcsr 0x0 [ ] + mxcsr 0x400440 [ DAZ OM ] ... This can be traced back to amd64_linux_nat_target::fetch_registers, where xstateregs is partially initialized by the ptrace call: ... char xstateregs[X86_XSTATE_MAX_SIZE]; struct iovec iov; amd64_collect_xsave (regcache, -1, xstateregs, 0); iov.iov_base = xstateregs; iov.iov_len = sizeof (xstateregs); if (ptrace (PTRACE_GETREGSET, tid, (unsigned int) NT_X86_XSTATE, (long) &iov) < 0) perror_with_name (_("Couldn't get extended state status")); amd64_supply_xsave (regcache, -1, xstateregs); ... after which amd64_supply_xsave is called. The amd64_supply_xsave call is supposed to only use initialized parts of xstateregs, but due to a kernel bug on intel skylake (fixed from 4.14 onwards by commit 0852b374173b "x86/fpu: Add FPU state copying quirk to handle XRSTOR failure on Intel Skylake CPUs") it can happen that the mxcsr part of xstateregs is not initialized, while amd64_supply_xsave expects it to be initialized, which explains the FAIL mentioned above. Fix the undetermined behaviour by initializing xstateregs before calling ptrace, which makes sure we get a 0x0 for mxcsr when this kernel bug occurs, and which also happens to fix the FAIL. Furthermore, add an xfail for this FAIL which triggers the same kernel bug: ... FAIL: gdb.arch/amd64-init-x87-values.exp: check_setting_mxcsr_before_enable: \ check new value of MXCSR is still in place ... Both FAILs pass when using a 5.3 kernel instead on the system mentioned above. Tested on x86_64-linux. gdb/ChangeLog: 2019-09-24 Tom de Vries <tdevries@suse.de> PR gdb/23815 * amd64-linux-nat.c (amd64_linux_nat_target::fetch_registers): Initialize xstateregs before ptrace PTRACE_GETREGSET call. gdb/testsuite/ChangeLog: 2019-09-24 Tom de Vries <tdevries@suse.de> PR gdb/24598 * gdb.arch/amd64-init-x87-values.exp: Add xfail.

2019-09-23Make ada_decode not use a static bufferChristian Biesinger1-0/+16
This makes it safer to use in general, and also allows using it on a background thread in the future. Inspired by tromey's patch at: https://github.com/tromey/gdb/commit/1226cbdfa436297a5dec054d94592c45891afa93 (however, implemented in a different way) gdb/ChangeLog: 2019-09-23 Christian Biesinger <cbiesinger@google.com> * ada-exp.y (write_object_remaining): Update. * ada-lang.c (ada_decode): Return a std::string instead of a char* and eliminate the static buffer.

2019-09-21gdb: change "nonzero" to "true" in commentsSimon Marchi1-0/+5
These int fields have been converted to bool, so their doc should say "true" and not "nonzero". gdb/ChangeLog: * breakpoint.h (bp_location) <inserted, permanent, duplicate>: Change "nonzero" to "true" in documentation.
2019-09-20Replace solib_global_lookup with gdbarch_iterate_over_objfiles_in_search_orderChristian Biesinger1-0/+17
All implementations of either function use it for the same purpose (except Darwin, which is a no-op): to prefer a symbol in the current objfile over symbols with the same name in other objfiles. There does not seem to be a reason to have both mechanisms for that purpose. gdb/ChangeLog: 2019-09-20 Christian Biesinger <cbiesinger@google.com> * solib-darwin.c (darwin_lookup_lib_symbol): Remove. (_initialize_darwin_solib): Don't set darwin_so_ops.lookup_lib_global_symbol. * solib-svr4.c (set_solib_svr4_fetch_link_map_offsets): Call set_gdbarch_iterate_over_objfiles_in_search_order.

2019-09-20Change TUI window commands to be case-sensitiveTom Tromey1-0/+7
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 Tromey1-0/+7
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 Tromey1-0/+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 Tromey1-0/+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.
2019-09-20Rename a private data member in tui_source_windowTom Tromey1-0/+8
This renames tui_source_window::fullname to add the "m_" prefix, as it is a private data member. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-source.h (struct tui_source_window) <m_fullname>: Rename from "fullname". * tui/tui-source.c (tui_source_window::set_contents) (tui_source_window::location_matches_p) (tui_source_window::maybe_update): Update.
2019-09-20Rename private data members of tui_data_windowTom Tromey1-0/+20
As Pedro suggested, this patch renames the private data members of tui_data_window to use the "m_" prefix. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-regs.h (struct tui_data_window) <get_current_group>: Update. <m_regs_content, m_regs_column_count, m_current_group>: Add "m_" prefix. * tui/tui-regs.c (tui_data_window::last_regs_line_no) (tui_data_window::line_from_reg_element_no) (tui_data_window::first_reg_element_no_inline) (tui_data_window::show_registers) (tui_data_window::show_register_group) (tui_data_window::display_registers_from) (tui_data_window::display_registers_from_line) (tui_data_window::first_data_item_displayed) (tui_data_window::delete_data_content_windows) (tui_data_window::erase_data_content) (tui_data_window::do_scroll_vertical) (tui_data_window::refresh_window) (tui_data_window::check_register_values): Update.
2019-09-20Change members of tui_locator_window to std::stringTom Tromey1-0/+11
This changes two members of tui_locator_window to have type std::string. This removes a static limit. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-stack.h (MAX_LOCATOR_ELEMENT_LEN): Remove define. (struct tui_locator_window) <full_name, proc_name>: Now std::string. * tui/tui-stack.c (tui_locator_window::make_status_line) (tui_locator_window::set_locator_fullname) (tui_locator_window::set_locator_info): Update. * tui/tui-source.c (tui_source_window::set_contents) (tui_source_window::showing_source_p): Update.
2019-09-20Remove a call to tui_locator_win_info_ptrTom Tromey1-0/+5
Commit e594a5d1 ("Turn two locator functions into methods") turned set_locator_fullname into a method on tui_locator_window. I missed it at the time, but this change allows for the removal of a call to tui_locator_win_info_ptr. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-stack.c (tui_locator_window::set_locator_fullname): Don't call tui_locator_win_info_ptr.
2019-09-20Don't call refresh in tui_resize_allTom Tromey1-0/+4
There's no reason to call refresh in tui_resize_all. This call flushes the curses window contents to the terminal -- but, because we're about the resize all the windows, we're going to be sending more data to the terminal momentarily. This patch removes the call. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-win.c (tui_resize_all): Don't call refresh.
2019-09-20Set TUI locator height to 1Tom Tromey1-0/+8
The TUI has long had code to resize the locator, using 2 as the height. However the code has "1" in a comment, like: locator->resize (2 /* 1 */ , This patch fixes the resizing code to set the height to 1. Doing this revealed what was probably the reason for setting the height to 2 in the first place: this caused the locator window to scroll. However, this is easily handled by calling scrollok on the locator window. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-win.c (tui_resize_all, tui_adjust_win_heights): Use 1 as height for locator. * tui/tui-stack.c (tui_locator_window::rerender): Call scrollok. * tui/tui-layout.c (show_source_disasm_command, show_data) (show_source_or_disasm_and_command): Use 1 as height for locator.
2019-09-20Change "win_resized" to boolTom Tromey1-0/+11
This changes the "win_resized" global to be a bool and then updates the uses. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_enable): Update. * tui/tui-win.c (tui_sigwinch_handler, tui_async_resize_screen): Update. * tui/tui-data.h (tui_win_resized, tui_set_win_resized_to): Update. * tui/tui-data.c (win_resized): Now bool. (tui_win_resized): Return bool. (tui_set_win_resized_to): Accept a bool.
2019-09-20Use "bool" in tui_data_window::show_register_groupTom Tromey1-0/+7
This changes tui_data_window::show_register_group to use "bool" rather than "int". gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-regs.h (struct tui_data_window) <show_register_group>: Change type of "refresh_values_only". * tui/tui-regs.c (tui_data_window::show_register_group): Change type of "refresh_values_only".
2019-09-20Simplify TUI disassemblyTom Tromey1-0/+7
This simplifies TUI disassembly somewhat, by removing manual memory management. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-disasm.c (struct tui_asm_line) <addr_string, insn>: Now std::string. (tui_disassemble): Add "pos" parameter. (tui_disasm_window::set_contents): Simplify.
2019-09-20Simplify tui_source_window_base::show_source_contentTom Tromey1-0/+8
tui_source_window_base::show_source_content is not used outside the class any more, so this makes it private. Examining the callers shows that it can't be called without source contents, so it can be simplified as well. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <show_source_content>: Now private. * tui/tui-winsource.c (tui_source_window_base::show_source_content): Don't handle empty content case.
2019-09-20Remove some explicit re-rendering from the TUITom Tromey1-0/+6
A couple of spots in tui-layout.c still call the show_source_content method. However, now that re-rendering is done by the resize method, these calls are no longer needed. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-layout.c (show_source_disasm_command) (show_source_or_disasm_and_command): Don't call show_source_content.
2019-09-20Change tui_make_status_line to be a methodTom Tromey1-0/+8
This changes tui_make_status_line to be a method on tui_locator_window. This is a minor cleanup. This also changes the new method to use the locator's width, rather than the terminal width. This is important if we ever want to allow windows to be made more narrow. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-stack.h (struct tui_locator_window) <make_status_line>: Declare. * tui/tui-stack.c (tui_locator_window::make_status_line): Rename from tui_make_status_line. (tui_locator_window::rerender): Update.
2019-09-20Change tui_make_status_line to return std::stringTom Tromey1-0/+5
This changes tui_make_status_line to return std::string. This cleans it up a bit, and removes some explicit memory management. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-stack.c (tui_make_status_line): Return std::string. (tui_locator_window::rerender): Update.
2019-09-20Move "fullname" to tui_source_windowTom Tromey1-0/+12
The "fullname" field in tui_source_window_base is only used by one subclass.

2019-09-19[gdb] Catch exception when constructing the highlighterTom de Vries1-0/+6
Currently in source_cache::ensure we catch the exception that triggers when highlighter->highlight is called: ... try { std::istringstream input (contents); std::ostringstream output; highlighter->highlight (input, output, lang_name, fullname); ... and the file used earlier in the construction of the highlighter: ... highlighter = new srchilite::SourceHighlight ("esc.outlang"); ... is missing. The fact that this exception triggers when highlighter->highlight is called is an implementation artefact of libsource-highlight.so though, and this could be different for older or newer versions. Make things more robust by also catching exceptions thrown during construction of the highlighter. This makes the handling on master equivalent with what has been committed for 8.3.1. Tested on x86_64-linux. gdb/ChangeLog: 2019-09-19 Tom de Vries <tdevries@suse.de> PR gdb/25009 * source-cache.c (source_cache::ensure): Catch exception thrown during construction of the highlighter.
2019-09-19bfd_section_* macrosAlan Modra1-0/+23
This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete.

2019-09-18Give a name to the TUI SingleKey keymapTom Tromey1-0/+7
Readline 8.0 has a feature that lets an application name a keymap. This in turn makes it simpler for users to bind keys in keymaps in their .inputrc. This patch gives a name to the TUI SingleKey keymap, so that additional bindings can be made there. For example: $if gdb set keymap SingleKey "X": "echo hello\\n\n" $endif The call to rl_initialize, in tui_initialize_readline, had to be removed so that .inputrc was not read too early. Note that Readline explicitly documents that this call is not needed. gdb/ChangeLog 2019-09-18 Tom Tromey <tom@tromey.com> * NEWS: Add entry. * tui/tui.c (tui_initialize_readline): Set name of keymap.

2019-09-17gdb: Look for compilation directory relative to directory search pathMike Gulick1-0/+7
The 'directory' command allows the user to provide a list of filesystem directories in which to search for source code. The directories in this search path are used as the base directory for the source filename from the debug information (DW_AT_name). Thus the directory search path provides alternatives to the existing compilation directory from the debug information (DW_AT_comp_dir). Generally speaking, DW_AT_name stores the filename argument passed to the compiler (including any directory components), and DW_AT_comp_dir stores the current working directory from which the compiler was executed. For example: $ cd /path/to/project/subdir1 $ gcc -c a/test.c -g The corresponding debug information will look like this: DW_AT_name : a/test.c DW_AT_comp_dir : /path/to/project/subdir1 When compiling with the -fdebug-prefix-map GCC option, the compilation directory can be arbitrarily rewritten. In the above example, we may rewrite the compilation directory as follows: $ gcc -c a/test.c -g -fdebug-prefix-map=/path/to/project= In this case, the corresponding debug information will look like: DW_AT_name : a/test.c DW_AT_comp_dir : /subdir1 This prevents GDB from finding the corresponding source code based on the debug information alone. In some cases, a substitute-path command can be used to re-map a consistent prefix in the rewritten compilation directory to the real filesystem path. However, there may not be a consistent prefix remaining in the debug symbols (for example in a project that has source code in many subdirectories under the project's root), thereby requiring multiple substitute-path rules. In this case, it is easier to add the missing prefix to the directory search path via the 'directory' command. The function find_and_open_source currently searches in: SEARCH_PATH/FILENAME where SEARCH_PATH corresponds to each individual entry in the directory search path (which is guaranteed to contain the compilation directory from the debug information, as well as the current working directory). FILENAME corresponds to the source filename (DW_AT_name), which may have directory components in it. In addition, GDB searches in: SEARCH_PATH/FILE_BASENAME where FILE_BASENAME is the basename of the DW_AT_name entry. This change modifies find_and_open_source to additionally search in: SEARCH_PATH/COMP_DIR/FILENAME where COMP_DIR is the compilation directory from the debug symbols. In the example given earlier, running: (gdb) directory /path/to/project will now allow GDB to correctly locate the source code from the debug information. gdb/ChangeLog: * source.c (prepare_path_for_appending): New function. (openp): Make use of new function. (find_and_open_source): Search for the compilation directory and source file as a relative path beneath the directory search path. gdb/doc/ChangeLog: * gdb.texinfo (Source Path): Additional text to better describe how the source path directory list is used when searching for source files. gdb/testsuite/ChangeLog: * gdb.base/source-dir.exp: Add extra test for mapped compilation directory.
2019-09-17gdb: Catch exceptions when accessing source cacheAndrew Burgess1-0/+6
The source_cache::get_line_charpos function can currently throw an exception if the source file is missing, which doesn't match the expected behaviour documented in the functions header file. The documented behaviour is to return false on failure, and this is how the function appears to be used throughout GDB. I spotted this in the 'info source' command, currently for a missing source file you'll see something like this: (gdb) info source Current source file is /path/to/src/file.c Compilation directory is /path/to/build/ /path/to/src/file.c: No such file or directory. (gdb) After this patch we see this: (gdb) info source Current source file is /path/to/src/file.c Compilation directory is /path/to/build/ Source language is c. Producer is COMPILER VERSION AND FLAGS. Compiled with DWARF 2 debugging format. Does not include preprocessor macro info. We don't currently indicate that the source file can't be found, and maybe that would be something worth adding in the future. gdb/ChangeLog: * source-cache.c (source_cache::get_line_charpos): Catch exceptions and return false, this matches the behaviour documented in the header file. gdb/testsuite/ChangeLog: * gdb.base/list-missing-source.exp: New file.
2019-09-17(Ada) do not print Ada task names in quotes in "info tasks" outputJoel Brobecker1-0/+4
A recent change enhanced a couple of notifications about Ada tasks to include the task's name in addition to the task's number. That change also modified the output of the "info tasks" when printing the detailed information of one given task. I believe this change was unintentionally left over from the initial version after it was decided that quoting the task's name should not be done. This patch therefore undoes this part of the patch. gdb/ChangeLog: * ada-tasks.c (info_task): Remove quoting of the task's name. Tested on x86_64-linux, with both the official testsuite as well as AdaCore's testsuite.
