2019-08-30Remove NULL checks from box_winTom Tromey2-19/+21
box_win can't be called with a NULL window, or with an invisible window. So, the NULL checks in that function can be removed. gdb/ChangeLog 2019-08-30 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (box_win): Assume win_info and win_info->handle cannot be NULL.
2019-08-30Simplify register displayTom Tromey4-58/+63
This patch starts with the observation that the code in tui_data_window::display_registers_from can all be replaced with a call to resize. To make this work propertly, it also changes tui_display_register to be the "rerender" method on tui_data_item_window. The refresh_window method is needed due to the use of nested windows here. The ncurses man page makes it sound like this is not very well supported; and experience bears this out: negelecting the touchwin call in this path will cause the register window to blank when switching focus. gdb/ChangeLog 2019-08-30 Tom Tromey <tom@tromey.com> * tui/tui-regs.h (struct tui_data_item_window) <rerender, refresh_window>: Declare. * tui/tui-regs.c (tui_data_window::display_registers_from): Call resize. (tui_data_item_window::rerender): Rename from tui_display_register. (tui_data_item_window::refresh_window): New method. * tui/tui-layout.c (tui_gen_win_info::resize): Do nothing on no-op.
2019-08-30Private data members in tui_data_windowTom Tromey4-7/+20
This changes tui_data_window so that the data members are private. This required the addition of a simple accessor method in one case. gdb/ChangeLog 2019-08-30 Tom Tromey <tom@tromey.com> * tui/tui-regs.h (struct tui_data_window) <regs_content, regs_column_count, current_group>: Move later. Now private. <get_current_group>: New method. * tui/tui-regs.c (tui_reg_command): Update. * tui/tui-layout.c (tui_set_layout): Update.
2019-08-30Remove some calls in tui_data_windowTom Tromey2-7/+9
This patch removes a call to erase_data_content in refresh_all and then removes some other calls that are more clearly unnecessary once one follows calls from that point. gdb/ChangeLog 2019-08-30 Tom Tromey <tom@tromey.com> * tui/tui-regs.c (tui_data_window::display_registers_from_line) (tui_data_window::rerender): Don't call check_and_display_highlight_if_needed. (tui_data_window::refresh_all): Remove call to erase_data_content.
2019-08-30Remove some checks of .empty()Tom Tromey2-111/+104
A few methods in tui_data_window check whether the contents are empty; but all the callers already check this, so these calls can be removed. gdb/ChangeLog 2019-08-30 Tom Tromey <tom@tromey.com> * tui/tui-regs.c (tui_data_window::last_regs_line_no) (tui_data_window::display_registers_from) (tui_data_window::display_reg_element_at_line) (tui_data_window::display_registers_from_line): Remove checks of "empty".
2019-08-30Remove tui_data_window::display_all_dataTom Tromey3-20/+11
tui_data_window::rerender clears the data item windows, and then calls display_all_data. However, that method only does anything if the contents are not empty. So, display_all_data can be renamed and the wrapper removed. gdb/ChangeLog 2019-08-30 Tom Tromey <tom@tromey.com> * tui/tui-regs.h (struct tui_data_window) <display_all_data>: Don't declare. * tui/tui-regs.c (tui_data_window::show_registers): Call rerender. (tui_data_window::rerender): Rename from display_all_data. (tui_data_window::rerender): Remove old implementation.
2019-08-30Remove NO_DATA_STRINGTom Tromey3-2/+7
NO_DATA_STRING shouldn't be used. It's referenced in a single spot, in tui_data_window::display_all_data. This patch removes the use and replaces it with the more correct text. A later patch (though not in this series) will remove this call entirely, when it's more obviously correct to do so. gdb/ChangeLog 2019-08-30 Tom Tromey <tom@tromey.com> * tui/tui-regs.c (tui_data_window::display_all_data): Change text. * tui/tui-data.h (NO_DATA_STRING): Remove define.
2019-08-29Run argv0-symlink.exp only on native target and local host.Sandra Loosemore2-0/+22
This testcase was originally for PR gdb/15415, a problem with the "run" command expanding symlinks in the name of the program being run. It does not correctly distinguish between files on build, host, and target, and it is not clear if it would be testing anything useful in configurations where "run" is not being used. 2019-08-29 Sandra Loosemore <sandra@codesourcery.com> * gdb.base/argv0-symlink.exp: Run only on native target and local host.
2019-08-29Fix PR win32/24284: tcp_auto_retry doesn't work in MinGWBernhard Wodok2-0/+17
This was reported by Bernhard Wodok, along with a patch to fix the issue. I adjusted the patch a bit, and I'm submitting the patch on his behalf. According to Bernhard, the issue can be reproduced by doing: 1. start gdb 2. enter 'target remote :2345' 3. observe that it throws a "connection refused" error immediately instead of waiting and throwing a timeout error I.e., I believe it can be reproduced by our current tests, which is why I'm not proposing any extra tests here (well, I don't use nor have any Windows system to test this, so...). The problem happens because, on ser-tcp:wait_for_connect, we call 'gdb_select' passing 0 as its first argument, which, when using MinGW, ends up using the 'gdb_select' version from mingw-hdep.c, and when the first argument is 0 this means that WaitForMultipleObjects will be called with 0 as its first argument as well. According to the MS API docs, this is forbidden: https://docs.microsoft.com/en-us/windows/win32/api/synchapi/nf-synchapi-waitformultipleobjects The proposed fix is simple: we just call Sleep when N == 0 (and when TIMEOUT is non-NULL), and return 0. It makes sense to me. Both Bernhard and Paul Carroll confirmed that the fix works. I'm Cc'ing Bernhard in case you have any questions about the patch.

2019-08-28gdb/fortran: Don't include module symbols when searching for typesAndrew Burgess5-2/+26
Currently the 'info types' command will return symbols that correspond to Fortran modules. This is because the symbols are created with domain MODULE_DOMAIN and address_class LOC_TYPEDEF. The address_class LOC_TYPEDEF is the same address_class used for type symbols which is why the modules show up when listing types. This commit explicitly prevents symbols in the MODULE_DOMAIN from appearing when we search for symbols in the TYPES_DOMAIN, this prevents the Fortran module symbols from appearing in the output of 'info types'. gdb/ChangeLog: * symtab.c (search_symbols): Don't include MODULE_DOMAIN symbols when searching for types. gdb/testsuite/ChangeLog: * gdb.fortran/info-types.exp: Add module. * gdb.fortran/info-types.f90: Update expected results.
2019-08-28gdb/fortran: Implement la_print_typedef for FortranAndrew Burgess8-1/+111
Implement an la_print_typedef method for Fortran, this allows 'info types' to work for Fortran. The implementation is just copied from ada_print_typedef (with the appropriate changes). To support the testing of this patch I added a new proc, fortran_character1, to lib/fortran.exp which returns a regexp to match a 1-byte character type. The regexp returned is correct for current versions of gFortran. All of the other regexp are guesses based on all of the other support procs in lib/fortran.exp, I haven't tested them myself. gdb/ChangeLog: * f-lang.c (f_language_defn): Use f_print_typedef. * f-lang.h (f_print_typedef): Declare. * f-typeprint.c (f_print_typedef): Define. gdb/testsuite/ChangeLog: * gdb.fortran/info-types.exp: New file. * gdb.fortran/info-types.f90: New file. * lib/fortran.exp (fortran_character1): New proc.

2019-08-26[gdb, c++] Improve error message when using libstdcxx without SDT probesTom de Vries4-2/+56
When using catch catch/rethrow/catch, a libstdcxx with SDT probes is required for both the regexp argument, and the convenience variable $_exception ( https://sourceware.org/gdb/current/onlinedocs/gdb/Set-Catchpoints.html ). Currently, when using these features with a libstdcxx without SDT probes, we get the cryptic error message: ... not stopped at a C++ exception catchpoint ...

2019-08-26Use raw strings on gdb.python/py-xmethods.exp (and fix Python 3.8's ↵Sergio Durigan Junior2-18/+23
"SyntaxWarning: invalid escape sequence") The way unrecognized escape sequences are handled has changed in Python 3.8: users now see a SyntaxWarning message, which will eventually become a SyntaxError in future versions of Python: (gdb) source /blabla/gdb.python/py-xmethods/py-xmethods.py /blabla/gdb.python/py-xmethods/py-xmethods.py:204: SyntaxWarning: invalid escape seque nce \+ 'operator\+', /blabla/gdb.python/py-xmethods/py-xmethods.py:211: SyntaxWarning: invalid escape seque nce \+ 'operator\+\+', One of our testcases, gdb.python/py-xmethods.exp, contains strings in the form of "operator\+". This is not recognized by Python, but is still needed by the testsuite to work properly. The solution is simple: we just have to make sure these strings are marked as raw (i.e, r""). This is what this patch does. I took the opportunity to also convert other strings to raw, which, in two cases, allowed the removal of an extra backslash. I tested this using Python 3.7 and Python 3.8, and everything works fine. I think I could push this as obvious, but decided to send it to gdb-patches just in case. gdb/testsuite/ChangeLog: 2019-08-26 Sergio Durigan Junior <sergiodj@redhat.com> * gdb.python/py-xmethods.exp: Use raw strings when passing arguments to SimpleXMethodMatcher.

2019-08-23Fix bug in nios2 prologue analysis.Sandra Loosemore2-3/+10
The nios2 prologue analyzer was mistakenly using an unsigned int field to represent a 32-bit signed value.

This patch fixes test failures in gdb.base/large-frame.exp and gdb.dwarf2/dw2-ref-missing-frame.exp.

Fix this by sorting the glob result. Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2019-08-21 Tom de Vries <tdevries@suse.de> * gdb.base/gdb-caching-proc.exp: Sort files.
2019-08-20Change some tui_data_window methods to be privateTom Tromey2-30/+39
Turning various calls into methods has made it possible to now change some tui_data_window methods to be private. 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-regs.h (struct tui_data_window) <last_regs_line_no, line_from_reg_element_no, first_reg_element_no_inline, display_all_data, delete_data_content_windows, erase_data_content>: Now private.
2019-08-20Remove some defines from tui-data.hTom Tromey3-7/+12
This removes the HILITE and NO_HILITE defines from tui-data.h, in favor of simply passing a bool to box_win. 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (box_win): Change type of highlight_flag. (tui_unhighlight_win, tui_highlight_win) (tui_win_info::make_window): Update. * tui/tui-data.h (HILITE, NO_HILITE): Remove.
2019-08-20Move some defines to tui-stack.cTom Tromey3-11/+21
Some #defines in tui-data.h are only used in tui-stack.c, so move them there. 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-data.h (PROC_PREFIX, LINE_PREFIX, PC_PREFIX) (MIN_LINE_WIDTH, MIN_PROC_WIDTH, MAX_TARGET_WIDTH) (MAX_PID_WIDTH): Move to tui-stack.c. * tui/tui-stack.c (PROC_PREFIX, LINE_PREFIX, PC_PREFIX) (MIN_LINE_WIDTH, MIN_PROC_WIDTH, MAX_TARGET_WIDTH) (MAX_PID_WIDTH): Move from tui-data.h.
2019-08-20Change tui_make_window to be a methodTom Tromey9-35/+49
I combined several small changes into one patch here. I believe I started by noticing that the "title" is not needed by tui_gen_win_info and could be self-managing (i.e. std::string). Moving this revealed that "can_box" is also a property of tui_win_info and not tui_gen_win_info; and this in turn caused the changes to tui_make_window and box_win. 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.h (tui_make_window): Don't declare. * tui/tui-wingeneral.c (box_win): Change type of win_info. (box_win): Update. (tui_gen_win_info::make_window): Rename from tui_make_window. (tui_win_info::make_window): New method. (tui_gen_win_info::make_visible): Update. * tui/tui-source.c (tui_source_window::set_contents): Update. * tui/tui-regs.c (tui_data_window::show_register_group): Update. (tui_data_window::display_registers_from): Update. * tui/tui-layout.c (tui_gen_win_info::resize): Update. * tui/tui-data.h (struct tui_gen_win_info) <make_window>: Declare. <can_box>: Remove. <title>: Remove. (struct tui_win_info) <make_window>: Declare. <can_box>: Now virtual. <title>: New member. * tui/tui-data.c (~tui_gen_win_info): Don't free title. * tui/tui-command.c (tui_cmd_window::resize): Update.
2019-08-20Remove tui_data_window::display_regsTom Tromey3-7/+7
There's no need for tui_data_window::display_regs any more (if there ever was). All the paths through data window construction will end up setting this to true. This patch removes the member. 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-regs.h (struct tui_data_window) <display_regs>: Remove. * tui/tui-regs.c (tui_data_window::show_registers): Update. (tui_data_window::check_register_values): Update.
2019-08-20Remove indirection from tui_data_window::regs_contentTom Tromey3-34/+38
tui_data_window::regs_content is currently a vector of unique_ptr. However, due to the way this is managed now, there is no need to keep the pointers -- it can simply be a vector of the objects themselves. This patch removes this extra layer of indirection. 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-regs.h (struct tui_data_window): Use DISABLE_COPY_AND_ASSIGN. <regs_content>: Change type, removing unique_ptr. <tui_data_window>: Add move constructor. * tui/tui-regs.c (tui_data_window::show_registers) (tui_data_window::show_register_group) (tui_data_window::display_registers_from) (tui_data_window::display_registers_from) (tui_data_window::first_data_item_displayed) (tui_data_window::delete_data_content_windows) (tui_data_window::rerender, tui_data_window::refresh_window) (tui_data_window::check_register_values): Update.
2019-08-20Add two methods to tui_data_windowTom Tromey4-35/+43
This changes tui_show_registers and tui_show_register_group to be methods on tui_data_window. 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-regs.h (struct tui_data_window) <show_registers, show_register_group>: Declare. (tui_show_register_group): Don't declare. * tui/tui-regs.c (tui_data_window::show_registers): Rename from tui_show_registers. (tui_data_window::show_register_group): Rename from tui_show_register_group. (tui_data_window::check_register_values, tui_reg_command): Update. * tui/tui-layout.c (tui_set_layout): Update.
2019-08-20Change tui_check_register_values to be a methodTom Tromey4-20/+28
This changes tui_check_register_values to be a method on tui_data_window. An additional check in tui_register_changed is needed, because TUI_DATA_WIN could be NULL at this point. 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-regs.h (struct tui_data_window) <check_register_values>: Declare. (tui_check_register_values): Don't declare. * tui/tui-regs.c (tui_data_window::check_register_values): Rename from tui_check_register_values. * tui/tui-hooks.c (tui_register_changed): Update.
2019-08-20Rearrange tui-regs.c some moreTom Tromey2-23/+20
This moves tui_reg_layout later in tui-regs.c, closer to where it is used. It also changes tui_show_registers not to enable the TUI or change the layout -- this is already done by this point by all the callers. 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-regs.c (tui_reg_layout): Move later. (tui_show_registers): Don't enable TUI mode or change layout.
2019-08-20Change tui_data_item_window::content to be a unique_xmalloc_ptrTom Tromey5-36/+33
This changes tui_data_item_window::content to be a unique_xmalloc_ptr and fixes up the fallout. It also removes a parameter from tui_expand_tabs, as it was only ever given one value. This also removes some tab-handling code from tui_data_window::display_registers_from. Because the content can only be set by tui_register_format, and because that calls tui_expand_tabs, it's not possible to see a tab here. gdb/ChangeLog 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-regs.h (struct tui_data_item_window) <~tui_data_item_window>: Remove. <content>: Now a unique_xmalloc_ptr. * tui/tui-regs.c (tui_register_format): Return a unique_xmalloc_ptr. (tui_get_register): Update. (~tui_data_item_window): Remove. (tui_data_window::display_registers_from, tui_display_register): Update. * tui/tui-io.h (tui_expand_tabs): Update. * tui/tui-io.c (tui_expand_tabs): Return a unique_xmalloc_ptr. Remove "col" parameter.
2019-08-20Remove tui_data_item_window::valueTom Tromey3-2/+6
The field tui_data_item_window::value is not used, so remove it. gdb/ChangeLog 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-regs.h (struct tui_data_item_window) <value>: Remove field. * tui/tui-regs.c (~tui_data_item_window): Update.
2019-08-20Minor rearrangement in tui-regs.cTom Tromey2-53/+53
This moves a couple of functions earlier in tui-regs.c. Previously they were in the "command" section of the file, but really they belong in the "window implementation" section. gdb/ChangeLog 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-regs.c (tui_register_format, tui_get_register): Move earlier.
2019-08-20Remove NULL check from tui_reg_commandTom Tromey2-3/+5
tui_reg_command has an unnecessary NULL check. The preceding call to tui_reg_layout will ensure the window exists. This patch removes the check. gdb/ChangeLog 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-regs.c (tui_reg_command): Remove NULL check.
2019-08-20Some i18n fixes for the TUITom Tromey5-6/+11
The TUI has a few #defines that hold user-visible strings. As these are only used in a single spot, this patch removes the defines, preferring direct use of the string where needed. Furthermore, now the strings are wrapped in _(), which is friendlier for i18n purposes. gdb/ChangeLog 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-source.h (struct tui_source_window): Update. * tui/tui-regs.c (tui_show_registers): Update. * tui/tui-disasm.h (struct tui_disasm_window): Update. * tui/tui-data.h (NO_SRC_STRING, NO_DISASSEM_STRING) (NO_REGS_STRING): Remove defines.
2019-08-20[gdb/testsuite] Clean up stale exec in gdb_compile_pascalTom de Vries2-0/+7
When running a pascal test with the stabs target board: ... $ test=gdb.pascal/case-insensitive-symbols.exp $ cd build/gdb/testsuite $ make check RUNTESTFLAGS="$test --target_board=stabs" ... we get: ... nr of untested testcases 1 nr of unsupported tests 1 ... due to: ... Error: Illegal parameter: -gstabs+^M Error: /usr/bin/ppcx64 returned an error exitcode^M ... OTOH, when running the same pascal test without the stabs target board: ... $ make check RUNTESTFLAGS="$test" ... we get: ... nr of expected passes 20 ... But when subsequently again running with the stabs target board: ... $ make check RUNTESTFLAGS="$test --target_board=stabs" ... we now get: ... nr of expected passes 20 ... The problem is that gdb_compile_pascal determines success based on existence of the exec after compilation: ... if ![file exists $destfile] { unsupported "Pascal compilation failed: $result" return "Pascal compilation failed." } ... without removing the exec before compilation, which allows a stale exec to make it seem as if compilation has succeeded. Fix this by removing the stale exec before compilation. gdb/testsuite/ChangeLog: 2019-08-20 Tom de Vries <tdevries@suse.de> * lib/pascal.exp (gdb_compile_pascal): Remove $destfile before compilation.
2019-08-20Improve remote attach round-trips without btraceConrad Meyer2-0/+10
For remotes which do not support btrace at all, we can save several round trips for each thread. This is especially significant when your remote is a kernel with 100s or 1000s of threads and latency is intercontinental. Previously, with target, remote, and infrun debugging enabled, one might see: Sending packet: $Hg18aee#43...Ack Packet received: OK Sending packet: $Hg186f7#eb...Ack Packet received: OK remote:target_xfer_partial (24, , 0x805454000, 0x0, 0x0, 4096) = -1, 0 repeated for all non-exited threads. Afterwards, if the remote does not specify 'qXfer:btrace-conf:read+' in qSupported stub features, these unnecessary thread switches are avoided. gdb/ChangeLog: * remote.c (remote_target::remote_btrace_maybe_reopen): Avoid unnecessary thread walk if remote doesn't support the packet.
2019-08-19Fix indentation in value_has_fieldTom Tromey2-1/+5
value_has_field had a mis-indented line. This fixes it. gdb/ChangeLog 2019-08-19 Tom Tromey <tromey@adacore.com> * python/py-value.c (value_has_field): Fix indentation.
2019-08-19Fix Fortran regression with variables in nested functionsTom Tromey4-11/+31
Sergio pointed out that commit commit aa3b6533 ("Allow nested function displays") regressed a few gdb.fortran tests. I was able to reproduce these failures with gcc head. The bug is that some spots calling contained_in will in fact do the wrong thing if nested functions are considered as contained. In the particular case of the Fortran regression, it was the call in block_innermost_frame, being called from get_hosting_frame -- in this case, the caller is specifically trying to avoid the nested case. This patch fixes the problem by adding an "allow_nested" parameter to contained_in, essentially reverting the change for most callers. gdb/ChangeLog 2019-08-19 Tom Tromey <tromey@adacore.com> * printcmd.c (do_one_display, info_display_command): Update. * block.h (contained_in): Return bool. Add allow_nested parameter. * block.c (contained_in): Return bool. Add allow_nested parameter.
