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.

2019-09-12gdb: Force use of float version of log10Andrew Burgess2-1/+7
This commit: commit aa17805fb9a3a1983a510ba425b682fba03410c2 Date: Sat Aug 31 23:44:40 2019 +0100 gdb: Have 'maint info sections' print all sections again introduced a use of log10 that took an int as a parameter. 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: 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.

2019-09-10Fix latent bug in .debug_names file-name handlingTom Tromey5-3/+72
An internal Ada test case showed that the .debug_names code does not compute the same list of file names as the partial symbol reader. In particular, the partial symbol reader uses the DW_AT_name of the CU: /* Allocate a new partial symbol table structure. */ filename = dwarf2_string_attr (comp_unit_die, DW_AT_name, cu); if (filename == NULL) filename = ""; pst = create_partial_symtab (per_cu, filename); This patch changes the .debug_names reader to follow. gdb/ChangeLog 2019-09-10 Tom Tromey <tromey@adacore.com> * dwarf2read.c (dw2_get_file_names_reader): Add the CU's file name to the results. gdb/testsuite/ChangeLog 2019-09-10 Tom Tromey <tromey@adacore.com> * gdb.ada/dgopt.exp: New file. * gdb.ada/dgopt/x.adb: New file.
