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.

This is a refactoring. Instead of a plain unsigned value, use an enum bitfield. gdb/ChangeLog: 2019-12-20 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * dwarf2read.c (is_valid_DW_AT_calling_convention_for_subroutine): New function.

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. After the callee returns, invoke the destructor of the temporary. gdb/ChangeLog: 2019-12-20 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> PR gdb/25054 * infcall.c (call_function_by_hand_dummy): Update the argument- passing section for call-by-value parameters.

2019-12-20infcall, c++: collect more pass-by-reference informationTankut Baris Aktemur2-51/+248
Walk through a given type to collect information about whether the type is copy constructible, destructible, trivially copyable, trivially copy constructible, trivially destructible. The previous algorithm returned only a boolean result about whether the type is trivially copyable. This patch computes more info. Additionally, it utilizes DWARF attributes that were previously not taken into account; namely, DW_AT_deleted, DW_AT_defaulted, and DW_AT_calling_convention. gdb/ChangeLog: 2019-12-20 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * gnu-v3-abi.c (enum definition_style): New enum type.

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.

2019-12-20gdb: recognize new DWARF attributes: defaulted, deleted, calling conv.Tankut Baris Aktemur4-1/+111
Extend GDB's internal representation of types to include the DW_AT_calling_convention, DW_AT_defaulted, and DW_AT_deleted attributes that were introduced in DWARF5. These attributes will be helpful in a future patch about infcall'ing functions with call-by-value parameters. GDB will use the attributes to decide whether the type of a call-by-value parameter is implicitly pass-by-reference. gdb/ChangeLog: 2019-12-20 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * dwarf2read.c (dwarf2_add_member_fn): Read the DW_AT_defaulted and DW_AT_deleted attributes of a function.

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. This was the last caller of tui_show_source, so this is removed as well. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_show_source): Remove. * tui/tui.h (tui_show_source): Don't declare. * tui/tui-out.c (tui_ui_out::do_field_string): Don't call tui_show_source.

2019-12-20Fix "list" command in the TUITom Tromey4-44/+106
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.

2019-12-20Reimplement 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.

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.

This changes tui_source_window_base::set_contents to return bool, rather than tui_status. It also changes one implementation of set_contents to use early returns rather than a variable, which IMO makes it easier to follow. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <set_contents>: Return bool. * tui/tui-winsource.c (tui_source_window_base::update_source_window_as_is): Update. * tui/tui-source.h (struct tui_source_window) <set_contents>: Return bool. * tui/tui-source.c (tui_source_window::set_contents): Return bool.

2019-12-20Remove tui_source_window::show_symtab_sourceTom Tromey4-17/+11
tui_source_window::show_symtab_source is identical to update_source_window, so remove the former. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_update_source_windows_with_addr) (tui_update_source_windows_with_line): Call update_source_window. * tui/tui-source.h (struct tui_source_window) <show_symtab_source>: Don't declare. * tui/tui-source.c (tui_source_window::show_symtab_source): Remove.

2019-12-20Remove tui_show_disassemTom Tromey4-19/+16
tui_show_disassem is just a wrapper for the update_source_window method, and it only has a single caller. This removes the function and inlines the logic into that caller. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_update_source_windows_with_addr): Call update_source_window directly. * tui/tui-disasm.h (tui_show_disassem): Don't declare. * tui/tui-disasm.c (tui_show_disassem): Remove.

2019-12-20Remove some unnecessary focus switchesTom Tromey3-12/+6
A couple of lower-level utility functions can change the TUI focus. This seems incorrect to me -- focus switches should only be done either by explicit user request, or ass a side effect of changing the layout. 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 switch focus. * tui/tui-disasm.c (tui_show_disassem): Don't switch focus.

2019-12-20Simplify tui_source_window_base::maybe_update methodTom Tromey7-25/+35
tui_source_window_base::maybe_update takes a symtab_and_line, plus a separate line number and PC. Because a symtab_and_line already holds a line number and a PC, it is possible to remove these extra parameters. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <maybe_update>: Remove line_no and addr parameters. * tui/tui-stack.c (tui_show_frame_info): Set PC on sal.

2019-12-20Remove some TUI assertsTom Tromey2-6/+5
This removes a few asserts from the TUI. These asserts aren't useful, because they simply check an invariant that's already ensured by the type system. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_source_window_base::set_is_exec_point_at) (tui_source_window_base::update_breakpoint_info): Remove asserts.

2019-12-20Remove tui_show_disassem_and_update_sourceTom Tromey4-37/+12
tui_show_disassem_and_update_source only has a single caller. This patch simplifies that caller, by having it call tui_show_disassem, and then removes tui_show_disassem_and_update_source. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_update_source_windows_with_addr): Call tui_show_disassem. * tui/tui-disasm.h (tui_show_disassem_and_update_source): Don't declare. * tui/tui-disasm.c (tui_show_disassem_and_update_source): Remove.

2019-12-20Remove parameters from tui_show_sourceTom Tromey4-4/+10
tui_show_source does not need its parameters, so this removes them. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui.h (tui_show_source): Remove parameters. * tui/tui.c (tui_show_source): Remove parameters. * tui/tui-out.c (tui_ui_out::do_field_string): Update.

2019-12-20Change tui_update_locator_fullname to take a symtabTom Tromey6-13/+21
This changes tui_update_locator_fullname to take a symtab. This somewhat consolidates the "??" handling. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_show_source): Update. * tui/tui-winsource.c (tui_display_main): Update. * tui/tui-stack.h (tui_update_locator_fullname): Change parameter to symtab. * tui/tui-stack.c (tui_update_locator_fullname): Change parameter to symtab. * tui/tui-disasm.c (tui_show_disassem_and_update_source): Update.

2019-12-20Make isearch change readline prompt in TUITom Tromey2-10/+8
PR tui/23619 points out that isearch changes the prompt in the CLI gdb (and in Bash) -- but not in the TUI. This turns out to be easily fixed by removing tui_rl_saved_prompt and instead using the prompt that readline computes. This is stored in rl_display_prompt, which according to git was added in readline 6.2. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> PR tui/23619: * tui/tui-io.c (tui_rl_saved_prompt): Remove.
