2020-01-03Ensure GDB warnings are styled.Philippe Waroquiers6-9/+35
While handling the comments of Tom related to [RFC] Have an option to tell GDB to detect and possibly handle mismatched exec-files. https://sourceware.org/ml/gdb-patches/2019-12/msg00621.html I saw that GDB warnings are produced ignoring the given styles. This patch: * ensures that style markups are properly handled by "warning". * changes 'set/show data-directory' so that file style is used in warnings and in 'show message' * changes all other messages in top.c to use file style when appropriate. * Uses the above data-directory changes in gdb.base/style.exp 2020-01-03 Philippe Waroquiers <philippe.waroquiers@skynet.be> * ui-file.c (stdio_file::can_emit_style_escape) (tee_file::can_emit_style_escape): Ensure style is used also on gdb_stderr when gdb_stderr is a tty supporting styling, similarly to gdb_stdout. * main.c (set_gdb_data_directory): Use file style to output the warning that the given pathname is not a directory. * top.c (show_history_filename, gdb_safe_append_history) (show_gdb_datadir): Use file style. 2020-01-03 Philippe Waroquiers <philippe.waroquiers@skynet.be> * gdb.base/style.exp: Test that warnings are styled.

2019-12-29Fix setting breakpoints or stepping on line 65535Bernd Edlinger5-6/+57
This removes code that was present from the very first git revisison 7b4ac7e1ed2c4616bce56d1760807798be87ac9e from 1988. It was in the gdb/dbxread.c at the time (and makes more sense for dbx line info format since line numbers are 16-bit entities in that debug format and debugging files with more than 65535 lines would not work anyway) but moved from there to gdb/buildsym.c which is used for dwarf line info as well, and excluding an arbitrary line number does certainly not make sense nowadays.

2019-12-27[PATCH] Adjust test gdb.ada/ptype_tagged_param.exp for when GNAT runtime ↵Simon Marchi4-4/+71
does not have debug info This test verifies that GDB correctly identifies the run-time type of "s" as being the type "Circle". However, that can only be done correctly if the GNAT runtime has been compiled and shipped with debug information, so that GDB can poke in its internal data structures. Currently the test fails when when running against a GNAT runtime without debug info. This is the case, for example, on Arch Linux using the distribution package. This patch adds a helper in lib/ada.exp to check whether the GNAT runtime has debug info or not. It then uses it in gdb.ada/ptype_tagged_param.exp to expect a different result, depending on whether we have debug info or not in the runtime. At first, I made it so we would XFAIL the test, in the absence of debug info, but then I thought that we might as well test for the output we expect in the absence of debug info instead. gdb/testsuite/ChangeLog: * lib/ada.exp (gnat_runtime_has_debug_info): New proc. * lib/gnat_debug_info_test.adb: New file. * gdb.ada/ptype_tagged_param.exp: Use gnat_runtime_has_debug_info, expect a different output if runtime does not have debug info.

2019-12-21Fix disabling of solib probes when LD_AUDITingGeorge Barrett2-1/+26
The SVR4 solib event handler determines whether an event is related to a non-base link namespace by comparing the event's debug struct address to the debug struct address of the initial program image. However, this can fail when using LD_AUDIT as audit libraries are loaded before the loader has initialised the initial program image's debug struct. When the event handler fails to find the debug struct, the probe-based debugger interface is disabled and a warning is flagged to the user. This commit adds a fallback test to help determine whether an event is for a foreign link namespace when the debug struct isn't available. gdb/ChangeLog: 2019-12-15 George Barrett <bob@bob131.so> * solib-svr4.c (svr4_handle_solib_event): Add fallback link namespace test for when the debug struct isn't available.

2019-12-20testsuite, cp: increase the coverage of testing pass-by-ref argumentsTankut Baris Aktemur5-86/+799
Extend testcases for GDB's infcall of call-by-value functions that take aggregate values as parameters. In particular, existing test has been substantially extended with class definitions whose definitions of copy constructor, destructor, and move constructor functions are a combination of (1) explicitly defined by the user, (2) defaulted inside the class declaration, (3) defaulted outside the class declaration, (4) deleted (5) not defined in the source. For each combination, a small and a large class is generated as well as a derived class and a container class. Additionally, the following manually-written cases are provided: - a dynamic class (i.e. class with a virtual method) - classes that contain an array field - a class whose copy ctor is inlined - a class whose destructor is deleted - classes with multiple copy and/or move ctors Test cases check whether GDB makes the right decision to pass an object by value or implicitly by reference, whether really a copy of the argument is passed, and whether the copy constructor and destructor of the clone of the argument are invoked properly. The input program pass-by-ref.cc is generated in the test's output directory. The input program pass-by-ref-2.cc is manually-written. Tests have been verified on the X86_64 architecture with GCC 7.4.0, 8.2.0, and 9.2.1. gdb/testsuite/ChangeLog: 2019-12-20 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * gdb.cp/pass-by-ref.cc: Delete.

2019-12-20infcall: handle pass-by-reference arguments appropriatelyTankut Baris Aktemur2-3/+132
If an aggregate argument is implicitly pass-by-reference, allocate a temporary object on the stack, initialize it via the copy constructor (if exists) or trivially by memcpy'ing. Pass the reference of the temporary to the callee function.

The previous algorithm returned only a boolean result about whether the type is trivially copyable. This patch computes more info.

2019-12-20infcall, c++: allow more info to be computed for pass-by-reference valuesTankut Baris Aktemur9-40/+131
In C++, call-by-value arguments that cannot be trivially copied are implicitly passed by reference. When making an infcall, GDB needs to find out if an argument is pass-by-reference or not, so that the correct semantics can be followed. This patch enriches the information computed by the language ops for pass-by-reference arguments. Instead of a plain binary result, the computed information now includes whether the argument is - copy constructible - destructible - trivially copyable - trivially copy constructible - trivially destructible This information is stored in a struct named 'language_pass_by_ref_info'. This patch paves the way for GDB's infcall mechanism to call the copy ctor and the destructor of a pass-by-ref argument appropriately. gdb/ChangeLog: 2019-12-20 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * language.h (struct language_pass_by_ref_info): New struct.

2019-12-20Don't call tui_show_source from tui_ui_outTom Tromey4-18/+8
This removes the call to tui_show_source from tui_ui_out. This always seemed like a hack, and now that the TUI is using the proper observers, it seems not to be needed. The rest of the logic remains, unfortunately, because it is needed to suppress some gdb output in the TUI case. We could probably find a nicer way to do this (maybe a ui_out_flag), but I haven't attempted this.

PR tui/18932 notes that "list" no longer works in the TUI. At some point in the past, it switched the TUI source window to show the specified source; but now this source briefly flashes before the TUI reverts to showing the current stack frame's source. This patch fixes this bug by introducing a new observer that notices when the user selected context has changed. Then, the existing before-prompt observer is updated to request the correct update: either one based on the current stack frame, or one based on the user's source symtab_and_line. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> PR tui/18932: * tui/tui-hooks.c (tui_refresh_frame_and_register_information): Rename parameters.

2019-12-20Add observable to watch current source symtabTom Tromey4-37/+89
This patch adds an observable, so that a later patch can change the TUI to notice when the user has selected a new source symtab, say via "list". gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * source.c (struct current_source_location) <set, symtab, line>: New methods. <m_symtab, m_line>: Rename.

2019-12-20Don't call set_current_source_symtab_and_line from TUITom Tromey2-7/+6
update_source_window_as_is calls set_current_source_symtab_and_line, but I don't think there is any reason it should be doing this. This patch removes the call. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_source_window_base::update_source_window_as_is): Don't call set_current_source_symtab_and_line.

2019-12-20Remove a call to update_exec_infoTom Tromey2-4/+6
tui_show_frame_info calls update_exec_info after calling erase_source_content, but there's no need to do this, as erase_source_content already clears the exec info. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-stack.c (tui_show_frame_info): Don't call update_exec_info.

2019-12-20Display "main" on initial TUI startupTom Tromey4-1/+11
I noticed that even when there's a symbol file, "tui enable" won't show "main" by default. I think it should, and this patch fixes this. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_enable): Call tui_display_main. gdb/testsuite/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * gdb.tui/list.exp: Check for source on initial listing.

2019-12-20Reimplement tui_get_begin_asm_addressTom Tromey2-14/+22
tui_get_begin_asm_address looks for the inferior's "main" to display it. I think this is incorrect in two ways. First, it should probably instead use the user's most recent source context, if one has been set. Second, it uses a hard-coded list of "main" names, but gdb already has a better approach to handling this. This patch fixes both of these problems. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-disasm.c (tui_get_begin_asm_address): Use get_current_source_symtab_and_line, and main_name.

2019-12-20Simplify tui_update_source_windows_with_lineTom Tromey4-31/+17

2019-12-20Simplify tui_update_source_windows_with_addrTom Tromey2-13/+9
After the previous changes, tui_update_source_windows_with_addr simply updates each source-like window separately, passing the same data to each. So, it can be simplified by using a loop instead. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_update_source_windows_with_addr): Simplify.

2019-12-20Use symtab_and_line when updating TUI windowsTom Tromey7-81/+88
This changes a few TUI source window methods to take a symtab_and_line rather than separate symtab and tui_line_or_address parameters. A symtab_and_line already incorporates the same information, so this seemed simpler. Also, it helps avoid the problem that the source and disassembly windows need different information -- both forms are present in the SAL. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <set_contents, update_source_window_as_is, update_source_window>: Take a sal, not a separate symtab and tui_line_or_address. * tui/tui-winsource.c (tui_source_window_base::update_source_window) (tui_source_window_base::update_source_window_as_is): Take a sal, not a separate symtab and tui_line_or_address.
