2019-06-04libctf: look for BSD versus GNU qsort_r signaturesNick Alcock10-85/+236
We cannot just look for any declaration of qsort_r, because some operating systems have a qsort_r that has a different prototype but which still has a pair of pointers in the right places (the last two args are interchanged): so use AC_LINK_IFELSE to check for both known variants of qsort_r(), and swap their args into a consistent order in a suitable inline function. (The code for this is taken almost unchanged from gnulib.) (Now we are not using AC_LIBOBJ any more, we can use a better name for the qsort_r replacement as well.) libctf/ * qsort_r.c: Rename to... * ctf-qsort_r.c: ... this.

2019-06-04libctf: fix the type of ctf_enum.cte_valueNick Alcock2-1/+5

2019-06-03Improve usability and/or readibility of help and apropos output.Philippe Waroquiers4-22/+69
The "help" command can output long list of command names or classes. Use the title style to style the command names or classes to make the output more readable. Similarly, change "apropos" command to also style the command names. It is sometimes unclear why "apropos REGEXP" lists some commands, and then the user has to manually do 'help command' for all commands listed by "apropos" to see more details about the matching commands. => Add an optional flag -v so that "apropos -v REGEXP": * outputs the full documentation of matching commands. * highlights the documentation parts matching REGEXP.
2019-06-03Add highlight style, title style, fputs_highlighted. Improve 'show style'Philippe Waroquiers5-34/+161
Have 'show style' and its subcommands using a style to style its output. This allows the GDB user or developer to use 'show style' to visually see with one command how all the current styles look like. Add 2 new styles highlight style, title style and fputs_highlighted function. Highlight style is used by fputs_highlighted to highlight the parts of its char *STR argument that match a HIGHLIGHT regexp. This (and the title style) will be used in a following patch.

2019-05-31Implement | (pipe) command.Philippe Waroquiers3-2/+116
The pipe command allows to run a GDB command, and pipe its output to a shell command: (gdb) help pipe Send the output of a gdb command to a shell command. Usage: | [COMMAND] | SHELL_COMMAND Usage: | -d DELIM COMMAND DELIM SHELL_COMMAND Usage: pipe [COMMAND] | SHELL_COMMAND Usage: pipe -d DELIM COMMAND DELIM SHELL_COMMAND Executes COMMAND and sends its output to SHELL_COMMAND. The -d option indicates to use the string DELIM to separate COMMAND from SHELL_COMMAND, in alternative to |. This is useful in case COMMAND contains a | character. With no COMMAND, repeat the last executed command and send its output to SHELL_COMMAND. (gdb) For example: (gdb) pipe print some_data_structure | grep -B3 -A3 something The pipe character is defined as an alias for pipe command, so that the above can be typed as: (gdb) | print some_data_structure | grep -B3 -A3 something If no GDB COMMAND is given, then the previous command is relaunched, and its output is sent to the given SHELL_COMMAND. This also defines convenience vars $_shell_exitcode and $_shell_exitsignal to record the exit code and exit signal of the last shell command launched by GDB e.g. by "shell", "pipe", ... gdb/ChangeLog 2019-05-31 Philippe Waroquiers <philippe.waroquiers@skynet.be> * cli/cli-cmds.c (pipe_command): New function.

2019-05-31Add previous_saved_command_line to allow a command to repeat a previous command.Philippe Waroquiers6-24/+125
Currently, a previous command can be repeated when the user types an empty line. This is implemented in handle_line_of_input by returning saved_command_line in case an empty line has been input. If we want a command to repeat the previous command, we need to save the previous saved_command_line, as when a command runs, the saved_command_line already contains the current command line of the command being executed. As suggested by Tom, the previous_saved_command_line is made static. At the same time, saved_command_line is also made static. The support functions/variables for the repeat command logic are now all located inside top.c. gdb/ChangeLog 2019-05-31 Philippe Waroquiers <philippe.waroquiers@skynet.be> * top.h (saved_command_line): Remove declaration. * top.c (previous_saved_command_line, previous_repeat_arguments): New variables.

2019-05-29Don't crash is dwarf_decode_macro_bytes's 'body' is NULL, even when '!is_define'Sergio Durigan Junior2-17/+22
Ref.: https://bugzilla.redhat.com/show_bug.cgi?id=1715008 On commit 7bede82892a06e6c26989803e70f53697392dcf9 ("Don't crash if dwarf_decode_macro_bytes's 'body' is NULL"), I was too strict when checking if 'body' is NULL: the check only comprised the case when 'is_define' is true. However, the corruption of .debug_macro by rpmbuild's "debugedit" also affects the case when 'is_define' is false, i.e., when the macro is being undefined. This commit improves the check and covers both cases now. This has been tested on Fedora 30 with a problematic debuginfo, and I don't see a segfault anymore.

2019-05-29Fix crash in cp_print_value_fieldsTom Tromey5-7/+90
PR c++/20020 concerns a crash in cp_print_value_fields. The immediate cause is that cp_print_value_fields does not handle the case where value_static_field fails. This is fixed in this patch by calling cp_print_static_field from the "try" block. Digging a bit deeper, the error occurs because GCC does not emit a DW_AT_const_value for a static constexpr member appearing in a template class. I've filed a GCC bug for this.

Implements "is_generic" and renames "is_generic_elf" to "uses_genelf", then uses these procs in lots of ld tests. moxie-elf -FAIL: ld-elf/orphan3 mt-elf -FAIL: ld-elf/merge s12z-elf -FAIL: ld-discard/extern s12z-elf -FAIL: ld-discard/start s12z-elf -FAIL: ld-discard/static s12z-elf -FAIL: PR ld/21703 s12z-elf -FAIL: PR ld/21703 -r s12z-elf -FAIL: Symbol flags copy s12z-elf -FAIL: ld-elf/group1 s12z-elf -FAIL: ld-elf/group3b s12z-elf -FAIL: ld-elf/group8a s12z-elf -FAIL: ld-elf/group8b s12z-elf -FAIL: ld-elf/group9a s12z-elf -FAIL: ld-elf/group9b s12z-elf -FAIL: ld-elf/linkonce2 s12z-elf -FAIL: ld-elf/merge2 s12z-elf -FAIL: ld-elf/merge3 s12z-elf -FAIL: ld-elf/pr12851 s12z-elf -FAIL: ld-elf/pr17550c s12z-elf -FAIL: ld-elf/pr17550d s12z-elf -FAIL: ld-elf/pr22677 s12z-elf -FAIL: ld-elf/pr22836-1a s12z-elf -FAIL: ld-elf/pr22836-1b s12z-elf -FAIL: ld-elf/warn1 s12z-elf -FAIL: ld-elf/warn3 binutils/ * testsuite/lib/binutils-common.exp (run_dump_test): Support tcl procedures for xfail args. ld/ * testsuite/lib/ld-lib.exp (run_ld_link_tests): Support procedure calls in optional "xfail" args.

2019-05-29Add "set print finish"Tom Tromey9-5/+87
A user wanted to be able to disable the display of the value when using "finish" -- but still have the value entered into the value history in case it was useful later on. Part of the rationale here is that sometimes the value might be quite large, or expensive to display (in their case this was compounded by a rogue pretty-printer). This patch implements this idea. gdb/ChangeLog 2019-05-29 Tom Tromey <tromey@adacore.com> * NEWS: Add entry. * infcmd.c (print_return_value_1): Handle finish_print option.

2019-05-28Remove find_old_style_renaming_symbolTom Tromey4-187/+22
We found a case where a "bt" was very slow with Ada code. Profiling with callgrind showed this to be primarily due to calls to find_old_style_renaming_symbol. Because new-style renaming symbols were implemented in 2007, it seems safe enough to remove this old code. A "-batch -ex bt" test on a large Ada program improves from: 13.23user 0.57system 0:13.82elapsed 99%CPU (0avgtext+0avgdata 571408maxresident)k to 4.25user 0.48system 0:04.74elapsed 99%CPU (0avgtext+0avgdata 559844maxresident)k with this patch. Tested on x86-64 Fedora 29.

2019-05-28binutils: CTF support for objdump and readelfNick Alcock10-27/+480
This introduces CTF support for objdump and readelf. objdump has the following new arguments: --ctf=SECTION: display CTF in the given SECTION --ctf-parent=SECTION: name of CTF section that is the parent of this section readelf has the above, and these two as well: --ctf-symbols=SECTION: name of symbol table section (optional) --ctf-strings=SECTION: name of string table section (optional) (objdump can always use BFD machinery to determine the applicable string and symbol tables automatically, so these arguments are unnecessary.) Nearly all the work is done by the ctf_dump machinery in libctf: most of the remaining work is option-processing and section-reading, and thus is different for objdump and readelf: the minimal amount of similar code remaining is, in my view, too small to share, particularly given that objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it doesn't have a bfd. I am not particularly satisfied with the way resources are freed in either of these (I was forced to do it at the top level, for lack of anywhere else to free resources allocated during option processing), but I can't see any better way to do it without introducing new infrastructure for no other purpose. There are essentially arbitrary ordering changes to the Makefile.in's order of libtool-related stuff that I can't get rid of, but they have no semantic effect. (It is possible that some hunks of these changes could be dropped, but that seems a bit risky to me.) binutils/ * objdump.c (ctf-api.h): New include. (dump_ctf_section_info): New variable.
