2019-05-14[gdb/doc] Fix "maint info selftests" command index entryTom de Vries2-1/+6
Currently, the entry for the command "maint info selftests" in the Command, Variable, and Function Index is listed at '"', rather than next to the other "maint info" commands. Fix this by removing the superfluous quoting in the @kindex entry. gdb/doc/ChangeLog: 2019-05-14 Tom de Vries <tdevries@suse.de> * gdb.texinfo (Maintenance Commands): Remove superfluous quoting on command index entry for "maint info selftests".

2019-05-10Fix GDB build when using --disable-gdbmiSimon Marchi7-32/+39
Since commit b4be1b064860 ("Fix MI output for multi-location breakpoints") we get this error when building with --disable-gdbmi: CXXLD gdb /home/smarchi/src/binutils-gdb/gdb/breakpoint.c:6358: error: undefined reference to 'mi_multi_location_breakpoint_output_fixed(ui_out*)' This is due to breakpoint.c using a function defined in mi/mi-main.c, even though mi/mi-main.c isn't included in the build. To fix it, use the flags feature of ui_out. mi_ui_out has the new fix_multi_location_breakpoint_output flag set for versions >= 3. Also, move the global variable fix_multi_location_breakpoint_output to breakpoint.c, so it can be read there even when we build without MI. I renamed it to fix_multi_location_breakpoint_output_globally so it doesn't clash with the new enumerator. gdb/ChangeLog: * breakpoint.h (fix_multi_location_breakpoint_output_globally): New variable declaration. * breakpoint.c (fix_multi_location_breakpoint_output_globally): New variable. (print_one_breakpoint): Use ui_out::test_flags and new global variable to compute use_fixed_output. * mi/mi-main.h (mi_multi_location_breakpoint_output_fixed): Remove. * mi/mi-main.c (fix_multi_location_breakpoint_output): Remove. (mi_multi_location_breakpoint_output_fixed): Remove. (mi_cmd_fix_multi_location_breakpoint_output): Adjust to set the new variable. * mi/mi-out.c (mi_ui_out::mi_ui_out): Set fix_multi_location_breakpoint_output flag if version >= 3. * ui-out.h (enum ui_out_flag) <fix_multi_location_breakpoint_output>: New enumerator.
2019-05-10cc-with-tweaks: show dwz stderr and verify resultSimon Marchi2-2/+36
When running the gdb.base/index-cache.exp test case with the cc-with-dwz-m board, I noticed that the final executable didn't actually contain a .gnu_debugaltlink section with the name of the external dwz file: $ readelf --debug-dump=links testsuite/outputs/gdb.base/index-cache/index-cache * empty * Running dwz by hand, I realized it's because dwz complains that the output .debug_info section is empty and fails: $ gcc ~/src/binutils-gdb/gdb/testsuite/gdb.base/index-cache.c -g3 -O0 -o a && cp a b $ dwz -m foo a b dwz: foo: .debug_info section not present $ echo $? 1 This is because index-cache.c is trivial (just an empty main) and dwz doesn't find anything to factor out to the dwz file. [1] I think that cc-with-tweaks should fail in this scenario: if the user asks for an external dwz file to be generated (the -m flag), then it should be an error if cc-with-tweaks doesn't manage to produce an executable with the proper link to this external dwz file. Otherwise, the test runs with a regular non-dwzified executable, which gives a false sense of security about whether the feature under test works with dwzified executables. So this patch adds checks for that after invoking dwz. It also removes the 2>&1 to allow the error message to be printed like so: Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.base/index-cache.exp ... gdb compile failed, dwz: /home/smarchi/build/binutils-gdb/gdb/testsuite/outputs/gdb.base/index-cache/index-cache.dwz: .debug_info section not present - In the -m case (multi-file compression), we check if the expected output file exists. - In the -z case (single-file compression), we check if the file contents has changed. This should catch cases where dwz doesn't modify the file because it's not worth it. It was chosen not to check for dwz's exit code, as it is not very reliable up to dwz 0.12. With this patch, fewer tests will pass than before with the cc-with-dwz and cc-with-dwz-m boards, but those were false positives anyway, as the test ran with regular executables. [1] Note that dwz has been patched by Tom de Vries to work correctly in this case, so we can use dwz master to run the test: https://sourceware.org/git/?p=dwz.git;a=commit;h=08becc8b33453b6d013a65e7eeae57fc1881e801 gdb/ChangeLog: * contrib/cc-with-tweaks.sh: Validate dwz's work.
2019-05-10Document lazy computation for pretty-printer "children" methodTom Tromey2-0/+11
I found out recently that some users didn't know that the Python pretty-printers "children" method should compute its result lazily. This has been a good idea since the earliest days, but wasn't mentioned in the docs. This patch adds some text to this effect. gdb/doc/ChangeLog 2019-05-10 Tom Tromey <tromey@adacore.com> * python.texi (Pretty Printing API): Mention lazy computation for "children".

2019-05-10Minor "catch" documentation improvementsTom Tromey2-8/+14
This patch makes a few minor improvements to the catchpoint documentation: * "catch exception" and "catch handlers" now mention the argument in the @item. * "catch exception unhandled" is moved to be closer to "catch exception", rather than after "catch handlers". * "catch load" and "catch unload" now wrap the argument in @var. gdb/doc/ChangeLog 2019-05-10 Tom Tromey <tromey@adacore.com> * gdb.texinfo (Set Catchpoints): Add text for parameter to "catch exception" and "catch handlers". Move "catch exception unhandled" text. Use @var for "catch load" and "catch unload"
2019-05-10Two minor constificationsTom Tromey5-4/+14
I noticed a couple of spots where a "char *" was used where a "const char *" made more sense. This patch fixes both of them. Tested by rebuilding. gdb/ChangeLog 2019-05-10 Tom Tromey <tromey@adacore.com> * thread.c (print_thread_info): Make "requested_threads" const. * gdbthread.h (print_thread_info): Make "requested_threads" const. * ada-tasks.c (print_ada_task_info): Make "taskno_str" const. * ada-lang.h (print_ada_task_info): Make "taskno_str" const.

This fixes a latent bug in swap_terminal_info, which previously said: terminal_info *info_a = (terminal_info *) inferior_data (a, inflow_inferior_data); terminal_info *info_b = (terminal_info *) inferior_data (a, inflow_inferior_data); ... both of which examine 'a'. gdb/ChangeLog 2019-05-08 Tom Tromey <tom@tromey.com> * inflow.c (struct terminal_info): Add destructor and initializers. (inflow_inferior_data): Change type. (~terminal_info): Rename from inflow_inferior_data_cleanup. (get_inflow_inferior_data, inflow_inferior_exit) (swap_terminal_info, _initialize_inflow): Update.

2019-05-08When debugging a mixed Ada/C program using this scenario:Xavier Roirand8-31/+207
- set print frame-arguements all - an Ada function named pck.call_me calls a C function named break_me - you put a breakpoint in break_me and the program reaches this breakpoint. Now display the backtrace: (gdb) bt #0 break_me () at [...] #1 0x000000000040243e in pck.call_me ( s={P_ARRAY = 0x7fffffffe21c, P_BOUNDS = 0x41e6e8}) at [...] whereas we should expect: (gdb) bt #0 break_me () at [...] #1 0x000000000040243e in pck.call_me (s="test") at [...] The problem is that GDB prints the S parameter in the pck.call_me Ada function using the current language, so the C one, because the program is stopped in a C function, whereas it should use the pck.call_me frame one. This behavior is ok when user manually changes the language but it's not the right one when language is auto. This patch fixes this problem so now when using auto language, all Ada frame arguments are printed using Ada like syntax when the frame is part of Ada code, even if the program is stopped in a frame using a different language. If the user explicitly sets a language (using "set language ...") then no change here, all the Ada frame arguments are printed using this language. gdb/ChangeLog: * ada-valprint.c (ada_val_print_gnat_array): Remove language parameter and use Ada language definition instead. (ada_val_print_ptr): Remove unused language parameter. (ada_val_print_num): Remove language parameter and use Ada language definition instead. (ada_val_print_enum, ada_val_print_flt): Remove unused language parameter. (ada_val_print_struct_union, ada_val_print_ref): Remove language parameter and use Ada language definition instead. (ada_val_print_1): Update all ada_val_print_xxx calls. Remove language parameter. (ada_val_print): Update ada_val_print_1 call. gdb/testsuite/ChangeLog: * gdb.ada/frame_arg_lang.exp: New testcase. * gdb.ada/frame_arg_lang/bla.adb: New file. * gdb.ada/frame_arg_lang/pck.ads: New file. * gdb.ada/frame_arg_lang/pck.adb: New file. * gdb.ada/frame_arg_lang/foo.c: New file. Tested on x86_64-linux, no regressions.
2019-05-08Change some remote.c globals to "static"Tom Tromey2-3/+9
I noticed a three globals in remote.c that could be static. This patch makes this change. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * remote.c (remote_hw_watchpoint_limit) (remote_hw_watchpoint_length_limit, remote_hw_breakpoint_limit): Now static.
2019-05-08Move "watchdog" to remote.cTom Tromey4-28/+34
The "watchdog" global is only used in remote.c, so this patch moves it there and makes it static. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * maint.c (_initialize_maint_cmds): Move initialization code to remote.c. (watchdog, show_watchdog): Move to remote.c. * remote.c (watchdog, show_watchdog): Move from maint.c. Make "watchdog" static. (_initialize_remote): Move initialization code from maint.c. * defs.h (watchdog): Don't declare.
2019-05-08Move interpreter_p declaration to main.hTom Tromey5-3/+12
This moves the interpreter_p declaration from defs.h to main.h. I think this makes more sense, as it is defined in main.c. Also, this declaration was in the wrong place -- between a comment and the things the comment described. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * tui/tui-interp.c: Include main.h. * interps.c: Include main.h. * main.h (interpreter_p): Declare. * defs.h (interpreter_p): Don't declare.
2019-05-08Don't declare read_unsigned_leb128 in defs.hTom Tromey4-4/+9
I noticed that read_unsigned_leb128 is declared in defs.h. There's no reason this should be here, so this patch moves it to dwarf2read.h. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * dwarf2loc.c: Include dwarf2read.h. * defs.h (read_unsigned_leb128): Don't declare. * dwarf2read.h (read_unsigned_leb128): Declare.
2019-05-08Fix build problem in fputs_maybe_filteredTom Tromey2-1/+6
When merging commit 99f20f ("Fix style bug when paging") to master, I had to make some changes to get it to compile again. Unfortunately, I must not have added these to the index at the correct time, because they were not committed. This patch fixes the problem. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * utils.c (fputs_maybe_filtered): Call can_emit_style_escape as a method.
2019-05-08Fix style bug when pagingTom Tromey2-3/+26
Philippe pointed out a styling bug that would occur in some conditions when paging: https://sourceware.org/ml/gdb-patches/2019-04/msg00101.html I was finally able to reproduce this, and this patch fixes the bug. The problem occurred when text overflowed the line, causing a pagination prompt, but when no wrap column had been set. In this case, the current style was reset to show the prompt, but then not reset back to the previously applied style before emitting the rest of the line. The fix is to record the applied style in this case, and re-apply it afterward -- but only if the pager prompt was emitted, something that the existing style.exp pointed out on the first, more naive, version of the patch. Tested on x86-64 Fedora 29. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * utils.c (fputs_maybe_filtered): Reset style after paging, even when no wrap column is set.
