2019-09-19[gdb] Catch exception when constructing the highlighterTom de Vries2-6/+12
Currently in source_cache::ensure we catch the exception that triggers when highlighter->highlight is called: ... try { std::istringstream input (contents); std::ostringstream output; highlighter->highlight (input, output, lang_name, fullname); ... and the file used earlier in the construction of the highlighter: ... highlighter = new srchilite::SourceHighlight ("esc.outlang"); ... is missing. The fact that this exception triggers when highlighter->highlight is called is an implementation artefact of libsource-highlight.so though, and this could be different for older or newer versions. Make things more robust by also catching exceptions thrown during construction of the highlighter. This makes the handling on master equivalent with what has been committed for 8.3.1. Tested on x86_64-linux. gdb/ChangeLog: 2019-09-19 Tom de Vries <tdevries@suse.de> PR gdb/25009 * source-cache.c (source_cache::ensure): Catch exception thrown during construction of the highlighter.

2019-09-19AArch64: Fix objdump testsTamar Christina2-2/+6
The newly added objdump -S tests check for source line mapping of a static variable. But the test doesn't dump any data sections so this should never pass. This changes the test to dump all sections so the source mapping can be found. binutils/ChangeLog: * testsuite/binutils-all/objdump.exp (objdump -S): Update testcases.
2019-09-19bfd_section_* macrosAlan Modra305-1996/+1917
This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete.

2019-09-18Give a name to the TUI SingleKey keymapTom Tromey5-3/+30
Readline 8.0 has a feature that lets an application name a keymap. This in turn makes it simpler for users to bind keys in keymaps in their .inputrc. This patch gives a name to the TUI SingleKey keymap, so that additional bindings can be made there. For example: $if gdb set keymap SingleKey "X": "echo hello\\n\n" $endif The call to rl_initialize, in tui_initialize_readline, had to be removed so that .inputrc was not read too early. Note that Readline explicitly documents that this call is not needed. gdb/ChangeLog 2019-09-18 Tom Tromey <tom@tromey.com> * NEWS: Add entry. * tui/tui.c (tui_initialize_readline): Set name of keymap.

2019-09-18binutils: doc: make `make clean` clean more thingsSimon Marchi3-6/+9
There is a bunch of things left over after a `make clean` in the doc directory. This patch changes the Makefile so that everything built by make is cleaned: - man pages (the man_MANS variable) - cxxfilt.man - binutils.info I am not sure why the last one was in MAINTAINERCLEANFILES. It's generated from binutils.texi using makeinfo, and it's not particularly long to build, so I don't see why it shouldn't be cleaned like the other files. Note: with my automake 1,15.1 (built from source), I get a spurious diff in Makefile.in, where the runstatedir = @runstatedir@ line gets removed. I am not sure why, but I haven't included it. binutils/ChangeLog: * doc/Makefile.am (MOSTLYCLEANFILES): Clean all man pages, cxxfilt.man and binutils.info.

2019-09-18binutils: doc: remove stale things from MakefileSimon Marchi3-28/+13
The `install-data-local: install-info` part: the comment refers to when the Makefile had the cygnus option. It no longer uses that, so the info file should get installed without that rule. I verified that `make install` still installed $(prefix)/share/info/binutils.info. The `DISTCLEANFILES` part: the comment talks about Automake 1.9, we are using 1.15.1, which doesn't appear to have this problem. binutils.info is built fine without this snippet. Note: with my automake 1,15.1 (built from source), I get a spurious diff in Makefile.in, where the runstatedir = @runstatedir@ line gets removed. I am not sure why, but I haven't included it. binutils/ChangeLog: * doc/Makefile.am (install-data-loca): Remove target. (DISTCLEANFILES): Remove variable. * doc/Makefile.in: Re-generate.
2019-09-18Re-generate many configure and Makefile.in filesSimon Marchi23-131/+80
I get some spurious changes when running autoconf/automake for various projects in the tree. This is likely because they were generated using distro-patched tools last time. I ran `autoreconf -f` in the various automake projects of the binutils-gdb tree, and this is the result. The tools I am using have been compiled from source, from the upstream release. bfd/ChangeLog: * Makefile.in: Re-generate. * configure: Re-generate. * doc/Makefile.in: Re-generate. binutils/ChangeLog: * Makefile.in: Re-generate. * configure: Re-generate. * doc/Makefile.in: Re-generate. gas/ChangeLog: * Makefile.in: Re-generate. * configure: Re-generate. * doc/Makefile.in: Re-generate. gold/ChangeLog: * testsuite/Makefile.in: Re-generate. gprof/ChangeLog: * Makefile.in: Re-generate. * configure: Re-generate. ld/ChangeLog: * Makefile.in: Re-generate. * configure: Re-generate. opcodes/ChangeLog: * Makefile.in: Re-generate. * configure: Re-generate.

Some versions of clang apparently generate non-PIC on powerpc64le to access common symbols. Since a common symbol and a strong definition with the same name should resolve to the strong definition we have the possibility of non-PIC attempting to access shared library variables.

2019-09-17gdb: Look for compilation directory relative to directory search pathMike Gulick7-42/+343
The 'directory' command allows the user to provide a list of filesystem directories in which to search for source code. The directories in this search path are used as the base directory for the source filename from the debug information (DW_AT_name). Thus the directory search path provides alternatives to the existing compilation directory from the debug information (DW_AT_comp_dir). Generally speaking, DW_AT_name stores the filename argument passed to the compiler (including any directory components), and DW_AT_comp_dir stores the current working directory from which the compiler was executed. For example: $ cd /path/to/project/subdir1 $ gcc -c a/test.c -g The corresponding debug information will look like this: DW_AT_name : a/test.c DW_AT_comp_dir : /path/to/project/subdir1 When compiling with the -fdebug-prefix-map GCC option, the compilation directory can be arbitrarily rewritten. In the above example, we may rewrite the compilation directory as follows: $ gcc -c a/test.c -g -fdebug-prefix-map=/path/to/project= In this case, the corresponding debug information will look like: DW_AT_name : a/test.c DW_AT_comp_dir : /subdir1 This prevents GDB from finding the corresponding source code based on the debug information alone. In some cases, a substitute-path command can be used to re-map a consistent prefix in the rewritten compilation directory to the real filesystem path. However, there may not be a consistent prefix remaining in the debug symbols (for example in a project that has source code in many subdirectories under the project's root), thereby requiring multiple substitute-path rules. In this case, it is easier to add the missing prefix to the directory search path via the 'directory' command. The function find_and_open_source currently searches in: SEARCH_PATH/FILENAME where SEARCH_PATH corresponds to each individual entry in the directory search path (which is guaranteed to contain the compilation directory from the debug information, as well as the current working directory). FILENAME corresponds to the source filename (DW_AT_name), which may have directory components in it. In addition, GDB searches in: SEARCH_PATH/FILE_BASENAME where FILE_BASENAME is the basename of the DW_AT_name entry. This change modifies find_and_open_source to additionally search in: SEARCH_PATH/COMP_DIR/FILENAME where COMP_DIR is the compilation directory from the debug symbols. In the example given earlier, running: (gdb) directory /path/to/project will now allow GDB to correctly locate the source code from the debug information. gdb/ChangeLog: * source.c (prepare_path_for_appending): New function. (openp): Make use of new function. (find_and_open_source): Search for the compilation directory and source file as a relative path beneath the directory search path. gdb/doc/ChangeLog: * gdb.texinfo (Source Path): Additional text to better describe how the source path directory list is used when searching for source files. gdb/testsuite/ChangeLog: * gdb.base/source-dir.exp: Add extra test for mapped compilation directory.
2019-09-17gdb: Catch exceptions when accessing source cacheAndrew Burgess4-10/+90
The source_cache::get_line_charpos function can currently throw an exception if the source file is missing, which doesn't match the expected behaviour documented in the functions header file. The documented behaviour is to return false on failure, and this is how the function appears to be used throughout GDB. I spotted this in the 'info source' command, currently for a missing source file you'll see something like this: (gdb) info source Current source file is /path/to/src/file.c Compilation directory is /path/to/build/ /path/to/src/file.c: No such file or directory. (gdb) After this patch we see this: (gdb) info source Current source file is /path/to/src/file.c Compilation directory is /path/to/build/ Source language is c. Producer is COMPILER VERSION AND FLAGS. Compiled with DWARF 2 debugging format. Does not include preprocessor macro info. We don't currently indicate that the source file can't be found, and maybe that would be something worth adding in the future. gdb/ChangeLog: * source-cache.c (source_cache::get_line_charpos): Catch exceptions and return false, this matches the behaviour documented in the header file. gdb/testsuite/ChangeLog: * gdb.base/list-missing-source.exp: New file.
2019-09-17(Ada) do not print Ada task names in quotes in "info tasks" outputJoel Brobecker2-3/+7
A recent change enhanced a couple of notifications about Ada tasks to include the task's name in addition to the task's number. That change also modified the output of the "info tasks" when printing the detailed information of one given task. I believe this change was unintentionally left over from the initial version after it was decided that quoting the task's name should not be done. This patch therefore undoes this part of the patch. gdb/ChangeLog: * ada-tasks.c (info_task): Remove quoting of the task's name. Tested on x86_64-linux, with both the official testsuite as well as AdaCore's testsuite.

Unfortunately this was causing a compilation error on Solaris, see: https://sourceware.org/ml/gdb-patches/2019-09/msg00230.html https://sourceware.org/ml/gdb-patches/2019-09/msg00231.html because there was only a float, double, or long double version of log10, and the compiler doesn't know which to choose. This commit should resolve this issue by casting the argument to float. gdb/ChangeLog: * maint.c (maint_print_section_data::maint_print_section_data): Force use of 'float log10 (float)' by casting the argument to float.
2019-09-12gdb/testsuite: Make use of exec_has_index_section functionAndrew Burgess2-12/+5
Make use of exec_has_index_section library function rather than manually checking in the 'maintenance info sections' output. Should make no difference to the test results, just makes the code easier to read. gdb/testsuite/ChangeLog: * gdb.base/maint.exp: Use exec_has_index_section.

This commit restores the old behaviour while keeping the important change that the above commit introduced, the addresses printed for sections are the relocated addresses where appropriate. 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.

2019-09-12gdb: Don't fault for 'maint print psymbols' when using an indexAndrew Burgess3-8/+29
I found that these tests: make check-gdb RUNTESTFLAGS="--target_board=cc-with-gdb-index gdb.base/maint.exp" make check-gdb RUNTESTFLAGS="--target_board=cc-with-debug-names gdb.base/maint.exp" were causing GDB to segfault. It turns out that this test runs this command: maint print psymbols -pc main /path/to/some/file which tries to lookup the partial_symtab for 'main'. The problem is that there is no partial_symtab for 'main' as we are using the .gdb_index or .debug_names instead of partial_symtabs. What happens is that maintenance_print_symbols calls find_pc_sect_psymtab, which looks for the partial_symtab in the objfile's objfile->partial_symtabs->psymtabs_addrmap. This is a problem because when we are using the indexes psymtabs_addrmap is reused to hold things other than partial_symtabs, this can be seen in dwarf2read.c in create_addrmap_from_index and create_addrmap_from_aranges. If we then lookup in psymtabs_addrmap we end up returning a pointer to something that isn't really a partial_symtab, after which everything goes wrong. Initially I simply added a check at the start of find_pc_sect_psymtab that the objfile had some partial_symtabs, like: if (objfile->partial_symtabs->psymtabs == NULL) return NULL; Figuring that if there were no partial_symtabs at all then this function should always return NULL, however, this caused a failure in the test gdb.python/py-event.exp which I didn't dig into too deeply, but seems to be that in this tests there are initially no psymtabs, but the second part of find_pc_sect_psymtab does manage to read some in from somewhere, with the check I added the test fails as we returned NULL here and this caused GDB to load in the full symtabs earlier than was expected. Instead I chose to guard only the access to psymtabs_addrmap with a check that the function has some psymtabs. This allows my original tests to pass, and the py-event.exp test to pass too. Now, a good argument can be made that we simply should never call find_pc_sect_psymtab on an objfile that is using indexes instead of partial_symtabs. I did consider this approach, we could easily add an assert into find_pc_sect_psymtab that if we find a partial_symtab in psymtabs_addrmap then the psymtabs pointer must be non-null. The responsibility would then be on the user of find_pc_sect_psymtab to ensure that the objfile being checked is suitable. In the end I didn't take this approach as the check in find_pc_sect_psymtab is cheap and this ensures that any future miss-uses of the function will not cause problems. I also extended the comment on psymtabs_addrmap to indicate that it holds more than just partial_symtabs as this was not at all clear from the original comment, and caused me some confusion when I was initially debugging this problem. gdb/ChangeLog: * psymtab.c (find_pc_sect_psymtab): Move baseaddr local into more inner scope, add check that the objfile has psymtabs before checking psymtabs_addrmap. * psymtab.h (psymtab_storage) <psymtabs_addrmap>: Extend comment.

2019-09-12[gdb/testsuite] Allow some tests in gdb.base/store.exp to be unsupportedTom de Vries2-20/+50
The test-case gdb.base/store.exp fails with gcc 7.4.0: ... nr of unexpected failures 27 ... The first FAIL: ... 110 l = add_float (l, r); (gdb) PASS: gdb.base/store.exp: continue to wack_float print l $21 = <optimized out> FAIL: gdb.base/store.exp: var float l; print old l, expecting -1 ... relates to this bit in the test-case (compiled at -O0): ... 106 float 107 wack_float (register float u, register float v) 108 { 109 register float l = u, r = v; 110 l = add_float (l, r); 111 return l + r; 112 } ... and it expects to be able to read and modify variable l before executing line 110, but it already fails to read the value, because l has no DW_AT_location attribute in the debug info. Variable l is declared with the register keyword, and GCC implements the register keyword at -O0 like so: ... the compiler allocates distinct stack memory for all variables that do not have the register storage-class specifier; if register is specified, the variable may have a shorter lifespan than the code would indicate and may never be placed in memory. ... The fact that l has no DW_AT_location attribute, matches with the documented "variable may have a shorter lifespan that code would indicate", (though it is the most extreme case of it) so the gcc behaviour is valid. We can of course improve gcc to generate better debuginfo (filed gcc PR91611), but this not a wrong-debug problem. [ The test-case passes with gcc 4.2.1, but for the failing test discussed above, it passes simply because it doesn't store l in a register. ] With the debug info missing for l, reading and setting l is unsupported, so fix the FAIL by marking the test UNSUPPORTED instead. Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2019-09-12 Tom de Vries <tdevries@suse.de> * gdb.base/store.exp: Allow register variables to be optimized out at -O0.
2019-09-12Output the Ada task name in more messages.Philippe Waroquiers8-21/+87
With this patch, we e.g. get: [Switching to task 2 "task_list(1)"] [Current task is 2 "task_list(1)"] instead of [Switching to task 2] [Current task is 2] The logic to produce the taskno optionally followed by the task name has been factorized in the task_to_str function. Task names are output between double quotes in the new messages, similarly to what GDB does for thread names. However, no quotes are put around task names in 'info tasks' Name column. This was discussed with Tom, that preferred no quotes there, while I was more in favour of visual consistency. I discussed with a few more users, which led to (exactly) 50% preferring quotes and 50% preferring no quotes :). To arrive to the decision to remove the quotes, the following "killing args" were used: * To have quotes or to not have quotes, that is the question; yes but not *THE* question :). * If there is not a clear majority that prefers quotes, better to not disturb the existing user basis for a (somewhat) irrelevant aspect. * The opinion of the reviewer has more weight. So, compared to the previous version, this version remotes the quotes in 'info tasks'. It improves the alignement of 'info tasks' output. With this patch, we get: (gdb) info task ID TID P-ID Pri State Name * 1 555555759030 48 Runnable main_task 2 555555759e30 1 48 Selective Wait mit (gdb) instead of (gdb) info task ID TID P-ID Pri State Name * 1 555555759030 48 Runnable main_task 2 555555759e30 1 48 Selective Wait mit (gdb) (e.g. the first one properly shows parent and priority under the correct header). This is version 4 of the 'task name' patch. Compared to version 3, the changes are: output task names between quotes but not in 'info tasks' gdb/ChangeLog 2019-09-12 Philippe Waroquiers <philippe.waroquiers@skynet.be> * NEWS: Announce that Ada task names are now shown at more places, and between quotes (except in info task output). * gdb/ada-tasks.c (task_to_str): New function.

2019-09-12PR24981, Hit assertion failure in ld/ldlang.c:7504Alan Modra2-2/+8
This fixes a problem with commit 128bf1fe608, a patch I made 2019-08-06. Apparently it is possible to trigger the assertion I added during an LTO bootstrap, something I haven't reproduced. However, I did find a case triggered by an odd linker script feature that allows a file to be loaded from the script without specifying that file on the command line. Regarding input sections: "When you use a file name which is not an archive:file specifier and does not contain any wild card characters, the linker will first see if you also specified the file name on the linker command line or in an INPUT command. If you did not, the linker will attempt to open the file as an input file, as though it appeared on the command line." So putting .foo : { foo.a(*) } into a script supposedly extracts foo.a into .foo. Except it doesn't, since this feature is meant for object files only. Well anyway, assuming --whole-archive was given on the command line, foo.a contains a -flto object and no other objects involved were -flto then we'll hit the assert due to files added like foo.a here *not* having their input statement put on the general statement list. Why these are not put on the statement list isn't obvious but it has been that way since commit 193c5f93a17 in 1994. PR 24981 * ldlang.c (lang_process): Remove assertion. Comment.
2019-09-12Fix signals reported for faults on SolarisRainer Orth2-33/+10
It's been a long-standing nuisance that gdb reported unaligned accesses on Solaris/SPARC as SIGSEGV, contrary to the shells and truss which correctly report SIGBUS instead. I could trace this down to the fault handling code in procfs.c (procfs_target::wait): when pr_why is set to PR_FAULTED, the current code sets the signal based on the fault number. For one, the code gets this wrong for FLTACCESS (the unaligned access case) where it uses SIGSEGV. What's worse, it's completely unnecessary to make up the signal number inside gdb. Instead, it should just take what procfs reports to avoid mismatches, which is what this patch does. I've completely removed the explicit handling of the various fault codes: for one, the list has already been incomplete, lacking FLTCPCOVF which existed since at least Solaris 8. Besides, there's no reason to error out on unknown fault codes: either the fault causes a signal which can then be reported from procfs, or it doesn't (as for FLTPAGE) and no reporting is necessary. Tested on sparcv9-sun-solaris2.11 and x86_64-pc-solaris2.11. Also spot-checked manually for a couple of cases (unaligned access, division by 0, NULL pointer dereference). * procfs.c (procfs_target::wait) <PR_FAULTED>: Get signal from prstatus.pr_lwp.pr_info instead of making it up.
