2024-01-12Update copyright year range in header of all files managed by GDBAndrew Burgess1-1/+1
This commit is the result of the following actions: - Running gdb/copyright.py to update all of the copyright headers to include 2024, - Manually updating a few files the copyright.py script told me to update, these files had copyright headers embedded within the file, - Regenerating gdbsupport/Makefile.in to refresh it's copyright date, - Using grep to find other files that still mentioned 2023. If these files were updated last year from 2022 to 2023 then I've updated them this year to 2024. I'm sure I've probably missed some dates. Feel free to fix them up as you spot them.
2023-10-09gdb/testsuite: match complete lines in gdb.base/maint.expAndrew Burgess1-2/+2
This thread: https://inbox.sourceware.org/gdb-patches/20231003195338.334948-1-thiago.bauermann@linaro.org/ pointed out that within gdb.base/maint.exp, some regexps within a gdb_test_multiple were failing to match a complete line, while later regexps within the gdb_test_multiple made use of the '^' anchor, and so assumed that earlier lines had been completely matched and removed from expect's buffer. When testing with READ1 set this assumption was failing. Fix this by extending the offending patterns with a trailing '\r\n'. Tested-by: Thiago Jung Bauermann <thiago.bauermann@linaro.org>
2023-03-22gdb/testsuite: adjust test cases to previous "maintenance info line-table" ↵Simon Marchi1-4/+4
change Commit 904d9b02a185 ("gdb: make "maintenance info line-table" show relocated addresses again") changed the format of that command, but failed to adjust some test cases that relied on it. This patch fixes it. The failures fixed are: FAIL: gdb.base/maint.exp: maint info line-table w/o a file name FAIL: gdb.dwarf2/dw2-out-of-range-end-of-seq.exp: END with address 1 eliminated FAIL: gdb.dwarf2/dw2-ranges-base.exp: count END markers in line table Change-Id: I946580d5e100f1beeac99a9e90d7819c6bb4ac6c
2023-01-26Eliminate spurious returns from the test suiteTom Tromey1-1/+0
A number of tests end with "return". However, this is unnecessary. This patch removes all of these.
2023-01-01Update copyright year range in header of all files managed by GDBJoel Brobecker1-1/+1
This commit is the result of running the gdb/copyright.py script, which automated the update of the copyright year range for all source files managed by the GDB project to be updated to include year 2023.
2022-12-05gdb/testsuite: remove perror calls when failing to runSimon Marchi1-1/+1
I noticed that when running these two tests in sequence: Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.ada/arrayptr.exp ... ERROR: GDB process no longer exists ERROR: Couldn't run foo-all Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.ada/assign_1.exp ... The results in gdb.sum are: Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.ada/arrayptr.exp ... PASS: gdb.ada/arrayptr.exp: scenario=all: compilation foo.adb ERROR: GDB process no longer exists UNRESOLVED: gdb.ada/arrayptr.exp: scenario=all: gdb_breakpoint: set breakpoint at foo.adb:40 (eof) ERROR: Couldn't run foo-all Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.ada/assign_1.exp ... UNRESOLVED: gdb.ada/assign_1.exp: changing the language to ada PASS: gdb.ada/assign_1.exp: set convenience variable $xxx to 1 The UNRESOLVED for arrayptr.exp is fine, as GDB crashes in that test, while trying to run to main. However, the UNRESOLVED in assign_1.exp doesn't make sense, GDB behaves as expected in that test: (gdb) set lang ada^M (gdb) UNRESOLVED: gdb.ada/assign_1.exp: changing the language to ada print $xxx := 1^M $1 = 1^M (gdb) PASS: gdb.ada/assign_1.exp: set convenience variable $xxx to 1 The problem is that arrayptr.exp calls perror when failing to run to main, then returns. perror makes it so that the next test (as in pass/fail) will be recorded as UNRESOLVED. However, here, the next test (as in pass/fail) is in the next test (as in .exp). Hence the spurious UNRESOLVED in assign_1.exp. These perror when failing to run to X are not really useful, especially since runto records a FAIL on error, by default. Remove all the perrors on runto failure I could find. When there wasn't one already, add a return statement when failing to run, to avoid running the test of the test unnecessarily. I thought of adding a check ran between test (in gdb_finish probably) where we would emit a warning if errcnt > 0, meaning a test quit and left a perror "active". However, reading that variable would poke into the DejaGNU internals, not sure it's a good idea. Change-Id: I2203df6d06e199540b36f56470d1c5f1dc988f7b
2022-11-28gdb/testsuite: remove use of then keyword from gdb.base/*.expAndrew Burgess1-1/+1
The canonical form of 'if' in modern TCL is 'if {} {}'. But there's still a bunch of places in the testsuite where we make use of the 'then' keyword, and sometimes these get copies into new tests, which just spreads poor practice. This commit removes all use of the 'then' keyword from the gdb.base/ test script directory. There should be no changes in what is tested after this commit.
2022-07-15gdb/testsuite: modernize gdb.base/maint.expBruno Larsen1-101/+45
gdb.base/maint.exp was using several gdb_expect statements, probably because this test case predates the existance of gdb_test_multiple. This commit updates the test case to use gdb_test_multiple, making it more resilient to internal errors and such. The only gdb_expect left in the testcase is one that specifically looks for an internal error being triggered as a PASS.
2022-05-11[gdb/testsuite] Fix gdb.base/maint.exp on powerpc64leTom de Vries1-1/+3
On powerpc64le-linux, I ran into: ... FAIL: gdb.base/maint.exp: maint print objfiles: symtabs ... The problem is that: - the "Cooked index in use" line occurs twice in the gdb output: - once for exec maint, and - once for "Object file system-supplied DSO". - the matching of the second "Cooked index in use" also consumes the "Symtabs:" string, and consequently the corresponding clause does not trigger and $symtabs remains 0. Fix this by limiting the output of the command to the exec. Tested on x86_64-linux and powerpcle-linux.
2022-04-12Enable the new DWARF indexerTom Tromey1-3/+11
This patch finally enables the new indexer. It is left until this point in the series to avoid any regressions; in particular, it has to come after the changes to the DWARF index writer to avoid this problem. However, if you experiment with the series, this patch can be moved anywhere from the patch to wire in the new reader to this point. Moving this patch around is how I got separate numbers for the parallelization and background finalization patches. In the ongoing performance example, this reduces the time from the baseline of 1.598869 to 0.903534.
2022-01-01Automatic Copyright Year update after running gdb/copyright.pyJoel Brobecker1-1/+1

2021-12-09[gdb/testsuite] Fix gdb.base/maint.exp with -readnowTom de Vries1-4/+4
With test-case gdb.base/maint.exp and target board -readnow, I run into: ... FAIL: gdb.base/maint.exp: maint info line-table w/o a file name ... The problem is that this and other regexps anchored using '^': ... -re "^$gdb_prompt $" { ... don't trigger because other regexps don't consume the entire preceding line. This is partly due to the addition of the IS-STMT column. Fix this by making the regexps consume entire lines. Tested on x86_64-linux with native and target board readnow, as well as check-read1 and check-readmore.
2021-12-03gdb/testsuite: fix two "maint info line-table"-related testsSimon Marchi1-0/+4
Commit 92228a334ba2 ("gdb: small "maintenance info line-table" readability improvements") change the output format of "maint info line-table" slightly, adding some empty lines between each line-table. This causes two tests to start failing, update them to account for those empty lines. Change-Id: I9d33a58fce3e860ba0554b25f5582e8066a5c519
2021-11-04gdb: introduce "set index-cache enabled", deprecate "set index-cache on/off"Simon Marchi1-3/+3
The "set index-cache" command is used at the same time as a prefix command (prefix for "set index-cache directory", for example), and a boolean setting for turning the index-cache on and off. Even though I did introduce that, I now don't think it's a good idea to do something non-standard like this. First, there's no dedicated CLI command to show whether the index-cache is enabled, so it has to be custom output in the "show index-cache handler". Also, it means there's no good way a MI frontend can find out if the index-cache is enabled. "-gdb-show index-cache" doesn't show it in the MI output record: (gdb) interpreter-exec mi "-gdb-show index-cache" ~"\n" ~"The index cache is currently disabled.\n" ^done,showlist={option={name="directory",value="/home/simark/.cache/gdb"}} Fix this by introducing "set/show index-cache enabled on/off", regular boolean setting commands. Keep commands "set index-cache on" and "set index-cache off" as deprecated aliases of "set index-cache enabled", with respectively the default arguments "on" and "off". Update tests using "set index-cache on/off" to use the new command. Update the regexps in gdb.base/maint.exp to figure out whether the index-cache is enabled or not. Update the doc to mention the new commands. Change-Id: I7d5aaaf7fd22bf47bd03e0023ef4fbb4023b37b3
2021-08-01[gdb/testsuite] Fix gdb.base/maint.exp with cc-with-gdb-indexTom de Vries1-13/+21
With target board cc-with-gdb-index we run into: ... FAIL: gdb.base/maint.exp: maint print statistics ... The output that is checked is: ... Statistics for 'maint':^M Number of "minimal" symbols read: 53^M Number of "full" symbols read: 40^M Number of "types" defined: 60^M Number of symbol tables: 7^M Number of symbol tables with line tables: 2^M Number of symbol tables with blockvectors: 2^M Number of read CUs: 2^M Number of unread CUs: 5^M Total memory used for objfile obstack: 20320^M Total memory used for BFD obstack: 4064^M Total memory used for string cache: 4064^M ... and the regexp doesn't match because it expects the "Number of read/unread CUs" lines in a different place. Fix this by updating the regexp. Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2021-08-01 Tom de Vries <tdevries@suse.de> * gdb.base/maint.exp: Update "maint print statistics" to match output with target board cc-with-gdb-index.
2021-04-27Fix timeout with maint print objfilesLuis Machado1-3/+0
I'm seeing timeouts from gdb.rust/traits.exp when we attempt to print things with "maint print objfiles". This happens for two reasons: 1 - GDB does not explicitly split each entry into its own line, but rather relies on the terminal's width to insert line breaks. 2 - When running the GDB testsuite, such width may be unlimited, which will prevent GDB from inserting any line breaks. As a result, the output may be too lengthy and will come in big lines. Tweak the support library to match the patterns line-by-line, which gives us more time to match things. Also fix GDB's output to print one entry per line, regardless of the terminal width. A similar approach was used in another testcase using the same command (commit eaeaf44cfdc9a4096a0dd52fa0606f29d4bfd48e). With the new line breaks, we don't need a particular pattern, so clean up that test as well. gdb/ChangeLog: 2021-04-27 Luis Machado <luis.machado@linaro.org> * psymtab.c (psymbol_functions::dump): Output newline. * symmisc.c (dump_objfile): Likewise. gdb/testsuite/ChangeLog: 2021-04-27 Luis Machado <luis.machado@linaro.org> * gdb.base/maint.exp: Drop a pattern that is not needed. * lib/gdb.exp (readnow): Match line-by-line.
2021-03-20Move psymtab statistics printing to psymtab.cTom Tromey1-1/+1
This moves all the psymtab statistics printing code form symmisc.c to psymtab.c. This changes the formatting of the output a little, but considering that it is a maint command (and, I assume, a rarely used one), this seems fine to me. This change helps further dissociate the psymtab from the objfile. In the end there will be no direct connect -- only via the quick_symbol_functions interface. gdb/ChangeLog 2021-03-20 Tom Tromey <tom@tromey.com> * dwarf2/read.c (dwarf2_base_index_functions::print_stats): Add print_bcache parameter. * symfile-debug.c (objfile::print_stats): Add print_bcache parameter. * quick-symbol.h (struct quick_symbol_functions) <print_stats>: Add print_bcache parameter. * symmisc.c (print_symbol_bcache_statistics, count_psyms): Move code to psymtab.c.

2021-02-11gdb/testsuite: split 'maint info sections' tests to a new fileAndrew Burgess1-87/+0
The next couple of patches are going to add more tests for the 'maint info sections' command. Rather than try to jam these tests into the already quite long gdb.base/maint.c, this commit moves all of the tests for 'maint info sections' into a new file. I've updated the tests to make use of some newer testsuite constructs, like -wrap and $gdb_test_name for gdb_test_multiple, but otherwise the tests should not have changed with this commit. gdb/testsuite/ChangeLog: * gdb.base/maint-info-sections.exp: New file, content is moved from gdb.base/maint.exp and cleaned up to use latest testsuite techniques. * gdb.base/maint.exp: Tests moved out to gdb.base/maint-info-sections.exp.

2020-04-17Replace most calls to help_list and cmd_show_listTom Tromey1-3/+3
Currently there are many prefix commands that do nothing but call either help_list or cmd_show_list. I happened to notice that one such call, for "set print type", used the wrong command list parameter, causing incorrect output. Rather than fix this bug in isolation, I decided to eliminate this possibility by adding two new ways to add prefix commands, which simply route the call to help_list or cmd_show_list, as appropriate. This makes it impossible for a mismatch to occur. In some cases, a bit of output was removed; however, I don't think this output in general was very useful. It seemed redundant with what's already printed by help_list. A representative example is this hunk, removed from ada-lang.c: - printf_unfiltered (_(\ -"\"set ada\" must be followed by the name of a setting.\n")); This simplified the CLI style set/show commands quite a bit, and allowed the deletion of a macro. This also cleans up some unusual code in windows-tdep.c. Tested on x86-64 Fedora 30.

2020-03-15[gdb/testsuite] Fix check-read1 FAIL with gdb.base/maint.expTom de Vries1-26/+19
When running test-case gdb.base/maint.exp with check-read1, I run into: ... FAIL: gdb.base/maint.exp: (timeout) maint print objfiles ... The FAIL happens because command output contains long lines like this: ... file1 at $hex, file2 at $hex, ..., $file$n at $hex, ... F.i., such a line for libc.so.debug contains 82000 chars. Fix this this by reading long lines bit by bit. Also, replace the testing of the command output formulated using a gdb_send combined with gdb_expect-in-a-loop, with a regular gdb_test_multiple with exp_continue. Tested on x86_64-linux, with make targets check and check-read1. gdb/testsuite/ChangeLog: 2020-03-15 Tom de Vries <tdevries@suse.de> * gdb.base/maint.exp: Use exp_continue in long lines for "maint print objfiles".

2020-01-24gdb: Include end of sequence markers in the line tableAndrew Burgess1-6/+14
In this commit: commit d9b3de22f33e400f7f409cce3acf6c7dab07dd79 Date: Wed May 27 14:44:29 2015 -0700 Add struct to record dwarf line number state machine. I believe an unintended change was made to how we store the DWARF line table, the end of sequence markers between sequences of lines were lost from the line table. This commit fixes this small oversight and restores the end of sequence markers. Given that we've survived this long without noticing is clearly an indication that this isn't that serious, however, a later patch that I am developing would benefit from having the markers in place, so I'd like to restore them. Having the markers also means that the output of 'maintenance info line-table' now more closely reflects the DWARF line table. I've taken this opportunity to improve how 'maintenance info line-table' displays the end of sequence markers - it now uses the END keyword, rather than just printing an entry with line number 0. So we see this: INDEX LINE ADDRESS 0 12 0x00000000004003b0 1 17 0x00000000004003b0 2 18 0x00000000004003b0 3 END 0x00000000004003b7 4 5 0x00000000004004a0 5 6 0x00000000004004a0 6 END 0x00000000004004a7 Instead of what we would have seen, which was this: INDEX LINE ADDRESS 0 12 0x00000000004003b0 1 17 0x00000000004003b0 2 18 0x00000000004003b0 3 0 0x00000000004003b7 4 5 0x00000000004004a0 5 6 0x00000000004004a0 6 0 0x00000000004004a7 I've added a small test that uses 'maintenance info line-table' to ensure that we don't regress this again. gdb/ChangeLog: * dwarf2read.c (lnp_state_machine::record_line): Include end_sequence parameter in debug print out. Record the line if we are at an end_sequence marker even if it's not the start of a statement. * symmisc.c (maintenance_print_one_line_table): Print end of sequence markers with 'END' not '0'. gdb/testsuite/ChangeLog: * gdb.base/maint.exp: Update line table parsing test. * gdb.dwarf2/dw2-ranges-base.exp: Add new line table parsing test.

The above commit mentions using this test: make check-gdb RUNTESTFLAGS="CFLAGS_FOR_TARGET='-pie' gdb.base/compare-sections.exp" And this still passes after this commit.

2019-06-06Add timestamps to "maint time" outputTom Tromey1-2/+5
Currently "maint time" will print the amount of time a command took. Sometimes, though, it's useful to have a timestamp as well -- for example if one is correlating a gdb log with some other log. This patch adds a timestamp to the start and end of each command when this setting is in effect. This also removes a "//" comment and changes scoped_command_stats to use DISABLE_COPY_AND_ASSIGN; two minor things I noticed while working on the patch. Tested on x86-64 Fedora 29. gdb/ChangeLog 2019-06-06 Tom Tromey <tromey@adacore.com> * maint.h (class scoped_command_stats): Use DISABLE_COPY_AND_ASSIGN. <print_time>: New method. * maint.c (scoped_command_stats, ~scoped_command_stats): Call print_time.

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
2018-08-07Add DWARF index cacheSimon Marchi1-0/+24
New in v3: - Remove things related to the dwarf-5 format. - Fix compilation on mingw (scoped_mmap.c). GDB can generate indexes for DWARF debug information, which, when integrated in the original binary, can speed up loading object files. This can be done using the gdb-add-index script or directly by the linker itself. However, not many people know about this. And even among those who do, because it requires additional steps, I don't know a lot of people who actually go through that trouble. To help make using the DWARF index more transparent, this patch introduces a DWARF index cache. When enabled, loading an index-less binary in GDB will automatically save an index file in ~/.cache/gdb. When loading that same object file again, the index file will be looked up and used to load the DWARF index. You therefore get the benefit of the DWARF index without having to do additional manual steps or modifying your build system. When an index section is already present in the file, GDB will prefer that one over looking up the cache. When doing my edit-compile-debug cycle, I often debug multiple times the same build, so the cache helps reducing the load time of the debug sessions after the first one. - The saved index file is exactly the same as the output of the "save gdb-index" command. It is therefore the exact same content that would be found in the .gdb_index or .debug_names section. We just leave it as a standalone file instead of merging it in the binary. - The cache is just a directory with files named after the object file's build-id. It is not possible to save/load the index for an object file without build-id in the cache. - The cache uses the gdb index format. The problem with the dwarf-5 format is that we can generate an addendum to the .debug_str section that you're supposed to integrate to the original binary. This complicates a little bit loading the data from the cached index files, so I would leave this for later. - The size taken up by ~/.cache/gdb is not limited. I was thinking we could add configurable limit (like ccache does), but that would come after. Also, maybe a command to flush the cache. - The cache is disabled by default. I think once it's been out there and tested for a while, it could be turned on by default, so that everybody can enjoy it. - The code was made to follow the XDG specification: if the XDG_CACHE_HOME environment variable, it is used, otherwise it falls back to ~/.cache/gdb. It is possible to change it using "set index-cache directory". On other OSes than GNU/Linux, ~/.cache may not be the best place to put such data. On macOS it should probably default to ~/Library/Caches/... On Windows, %LocalAppData%/... I don't intend to do this part, but further patches are welcome. - I think that we need to be careful that multiple instances of GDB don't interfere with each other (not far fetched at all if you run GDB in some automated script) and the cache is always coherent (either the file is not found, or it is found and entirely valid). Writing the file directly to its final location seems like a recipe for failure. One GDB could read a file in the index while it is being written by another GDB. To mitigate this, I made write_psymtabs_to_index write to temporary files and rename them once it's done. Two GDB instances writing the index for the same file should not step on each other's toes (the last file to be renamed will stay). A GDB looking up a file will only see a complete file or no file. Also, if GDB crashes while generating the index file, it will leave a work-in-progress file, but it won't be picked up by other instances looking up in the cache. gdb/ChangeLog: * common/pathstuff.h (get_standard_cache_dir): New. * common/pathstuff.c (get_standard_cache_dir): New. * build-id.h (build_id_to_string): New. * dwarf-index-common.h (INDEX4_SUFFIX, INDEX5_SUFFIX, DEBUG_STR_SUFFIX): Move to here. * dwarf-index-write.c (INDEX4_SUFFIX, INDEX5_SUFFIX, DEBUG_STR_SUFFIX): Move from there.

2018-07-26gdb: Add switch to disable DWARF stack unwindersAndrew Burgess1-0/+4
Add a maintenance command to disable the DWARF stack unwinders. Normal users would not need this feature, but it is useful to allow extended testing of fallback stack unwinding strategies, for example, prologue scanners. This is a partial implementation of the idea discussed in pr gdb/8434, which talks about a generic ability to disable any frame unwinder. Being able to arbitrarily disable any frame unwinder would be a more complex patch, and I was unsure how useful such a feature would really be, however, I can see (and have) a real need to disable DWARF unwinders. That's why this patch only targets that specific set of unwinders. If in the future we find ourselves adding more switches to disable different unwinders, then we should probably move to a more generic solution, and remove this patch. gdb/ChangeLog: * dwarf2-frame-tailcall.c (tailcall_frame_sniffer): Exit early if DWARF unwinders are disabled. * dwarf2-frame.c: Add dwarf2read.h include. (dwarf2_frame_sniffer): Exit early if DWARF unwinders are disabled. (dwarf2_frame_unwinders_enabled_p): Define. (show_dwarf_unwinders_enabled_p): New function.

2018-06-01Remove TYPE_TAG_NAMETom Tromey1-1/+1
TYPE_TAG_NAME has been an occasional source of confusion and bugs. It seems to me that it is only useful for C and C++ -- but even there, not so much, because at least with DWARF there doesn't seem to be any way to wind up with a type where the name and the tag name are both non-NULL and different. So, this patch removes TYPE_TAG_NAME entirely. This should save a little memory, but more importantly, it simplifies this part of gdb. A few minor test suite adjustments were needed. In some situations the new code does not yield identical output to the old code. gdb/ChangeLog 2018-06-01 Tom Tromey <tom@tromey.com> * valops.c (enum_constant_from_type, value_namespace_elt) (value_maybe_namespace_elt): Update. * valarith.c (find_size_for_pointer_math): Update. * target-descriptions.c (make_gdb_type): Update. * symmisc.c (print_symbol): Update. * stabsread.c (define_symbol, read_type) (complain_about_struct_wipeout, add_undefined_type) (cleanup_undefined_types_1): Update. * rust-lang.c (rust_tuple_type_p, rust_slice_type_p) (rust_range_type_p, val_print_struct, rust_print_struct_def) (rust_internal_print_type, rust_composite_type) (rust_evaluate_funcall, rust_evaluate_subexp) (rust_inclusive_range_type_p): Update. * python/py-type.c (typy_get_tag): Update. * p-typeprint.c (pascal_type_print_base): Update. * mdebugread.c (parse_symbol, parse_type): Update. * m2-typeprint.c (m2_long_set, m2_record_fields, m2_enum): Update. * guile/scm-type.c (gdbscm_type_tag): Update. * go-lang.c (sixg_string_p): Update. * gnu-v3-abi.c (build_gdb_vtable_type, build_std_type_info_type): Update. * gdbtypes.h (struct main_type) <tag_name>: Remove.

2018-05-04gdb: Make test names unique in gdb.base/maint.expAndrew Burgess1-16/+9
Add prefixes or suffixes to some test names to make them unique. Replace a send_gdb/gdb_expect with a gdb_test, and make the test name unique. Remove test of 'help maint' as this is already covered by a later call to test_prefix_command_help. Removed test of 'help maint info' and add a new call to test_prefix_command_help instead. gdb/testsuite/ChangeLog: * gdb.base/maint.exp: Make test names unique, use test_prefix_command_help to test 'help maint info', and remove repeated test of 'help maint'.
2018-05-04gdb/testsuite: Handle targets with lots of registersAndrew Burgess1-2/+22
In gdb.base/maint.exp a test calls 'maint print registers'. If the target has lots of registers this may overflow expect's buffers, causing the test to fail. After this commit we process the output line at a time until we get back to the GDB prompt, this should prevent buffer overrun while still testing that the command works as required. gdb/testsuite/ChangeLog: * gdb.base/maint.exp: Process output from 'maint print registers' line at a time.

Some testcases needed to be updated as they were missing .debug_aranges. While that does not matter for no-index (as GDB builds the mapping internally during dwarf2_build_psymtabs_hard) and neither for .gdb_index (as GDB uses that internally built mapping which it stores into .gdb_index) it does matter for .debug_names as that simply assumes existing .debug_aranges from GCC. gdb/ChangeLog: 2017-12-08 Jan Kratochvil <jan.kratochvil@redhat.com> Pedro Alves <palves@redhat.com> * defs.h (elf_sym_fns_debug_names): New declaration. * dwarf2read.c: Include "hash_enum.h".

2016-12-22New syntax for mt print symbols,msymbols,psymbols.Doug Evans1-67/+69
gdb/ChangeLog: * NEWS: Document new syntax for "mt print symbols", "mt print psymbols" and "mt print msymbols" commands. * psymtab.c (DEV_TTY): Delete. (dump_psymtab_addrmap): Don't dump if psymtabs_addrmap is NULL. (maintenance_print_psymbols): Rewrite for new syntax: mt print psymbols [-objfile objfile] [-pc address] [outfile] mt print psymbols [-objfile objfile] [-source source] [outfile] (_initialize_psymtab): Update help text. * symmisc.c (maintenance_print_symbols): Rewrite for new syntax: mt print symbols [-pc address] [outfile] mt print symbols [-objfile objfile] [-source source] [outfile] (maintenance_print_msymbols): Rewrite for new syntax: mt print msymbols [-objfile objfile] [outfile] Only print symbols for the current progspace. (_initialize_symmisc): Update help text. gdb/doc/ChangeLog: * gdb.texinfo (Symbols): Update docs for symbol printing maintenance commands. gdb/testsuite/ChangeLog: * gdb.base/maint.exp: Update tests for maint print symbols, psymbols and msymbols.
2016-12-02Remove unneeded pattern matching in gdb.base/maint.expLuis Machado1-16/+4
This gets rid of more useless pattern matching cases in gdb.base/maint.exp. gdb/testsuite/ChangeLog: 2016-12-02 Luis Machado <lgustavo@codesourcery.com> * gdb.base/maint.exp: Use gdb_test instead of gdb_test_multiple when possible. Remove useless pattern-matching code.
2016-12-01Don't handle timeout inside gdb_test_multipleLuis Machado1-9/+0
This fixes a few cases where the testcase is explicitly handling timeouts inside gdb_test_multiple when it is not necessary. It also converts two gdb_test_multiple calls to gdb_test_no_output calls (also removing the timeout handling). gdb/testsuite/ChangeLog: 2016-12-01 Luis Machado <lgustavo@codesourcery.com> * gdb.base/maint.exp: Remove timeout handling for gdb_test_multiple. * gdb.cp/gdb2495.exp: Likewise and convert gdb_test_multiple into gdb_test_no_output for a couple of cases. * gdb.cp/ovldbreak.exp: Remove timeout handling for gdb_test_multiple.
2016-10-28gdb/testsuite: Avoid a buffer overrun in `gdb.base/maint.exp'Pedro Alves1-3/+35
Fixes: PASS: gdb.base/maint.exp: maint w/o args ERROR: internal buffer is full. UNRESOLVED: gdb.base/maint.exp: maint info line-table w/o a file name The problem is just many symtabs and long line tables, enough to overflow the expect buffer. Fix this by matching input incrementally. gdb/testsuite/ChangeLog: 2016-10-28 Pedro Alves <palves@redhat.com> * gdb.base/maint.exp <maint info line-table w/o a file name>: Use gdb_test_multiple, tighten regexps and match symtabs and line tables incrementally.
2016-07-15GDB testsuite: Escape paths used in regular expressionsDon Breazeal1-6/+9
This patch fixes problems with a few GDB testsuites when executing in a path that contains special characters (e.g. "++"). When such paths are used as a regular expression, the regular expression parser will choke and cause the tests to fail. This patch uses string_to_regexp to escape strings that will be used as regular expressions, in order to sanitize path names used in expect scripts. 2016-07-15 Zachary Welch <zwelch@codesourcery.com> Don Breazeal <donb@codesourcery.com> gdb/testsuite/ChangeLog: * gdb.base/maint.exp: Escape paths used in regular expressions. * gdb.stabs/weird.exp: Likewise.
2016-03-11gdb: New maint info line-table command.Andrew Burgess1-0/+20
Add a new command 'maint info line-table' to display the contents of GDB's internal line table structure. Useful when trying to understand problems (within gdb) relating to line tables. gdb/ChangeLog: * symmisc.c (maintenance_info_line_tables): New function. (maintenance_print_one_line_table): New function. (_initialize_symmisc): Register 'maint info line-table' command. * NEWS: Mention new command. gdb/doc/ChangeLog: * gdb.texinfo (Symbols): Document new 'maint info line-table' command. gdb/testsuite/ChangeLog: * gdb.base/maint.exp: New tests for 'maint info line-table'.
