2019-08-09Add support for a MIPS specific .MIPS.xhash section.Mihailo Stojanovic24-48/+314
This patch is a reimplementation of [1] which was submitted in 2015 by Neil Schellenberger. Copyright issue was sorted out [2] last year. It proposed a new section (.gnu.xhash) and related dynamic tag (DT_GNU_XHASH). The new section would be virtually identical to the existing .gnu.hash except for the translation table (xlat) which would contain correct MIPS .dynsym indexes corresponding to the hashvals in chains. This is because MIPS ABI imposes a different ordering on the dynsyms than the one expected by the .gnu.hash section. Another addition would be a leading word (ngnusyms) which would contain the number of entries in the translation table. In this patch, the new section name and dynamic tag are changed to reflect the fact that the section should be treated as MIPS-specific (.MIPS.xhash and DT_MIPS_XHASH). This patch addresses the alignment issue as reported in [3], which is caused by the leading word added to the .MIPS.xhash section. Leading word is removed in this patch, and the number of entries in the translation table is now calculated using DT_MIPS_SYMTABNO dynamic tag (this is addressed by the corresponding glibc patch). Suggestions on coding style in [4] were taken into account. Existing GNU hash testcase was covered, and another one was added in the MIPS part of the testsuite. The other major change is reserving MIPS ABI version 5 for .MIPS.xhash, marking the need of support for .MIPS.xhash in the dynamic linker (again, addressed in the corresponding glibc patch). This is something which I am not sure of, especially after reading [5]. I am confused on whether this ABI version is reserved for IFUNC, or it can be used for this purpose.

With target board unix/-fPIE/-pie, we get: ... FAIL: gdb.dwarf2/varval.exp: print varval2 ... This is due comparing a get_frame_pc result (which includes the for PIE non-zero relocation offset) with pc_high and pc_low obtained using get_scope_pc_bounds (which do not include the relocation offset). Fix this by adjusting pc_high and pc_low with the relocation offset.

2019-08-07AArch64 pauth: Indicate unmasked addresses in backtraceAlan Hayward9-11/+82
Armv8.3-a Pointer Authentication causes the function return address to be obfuscated on entry to some functions. GDB must unmask the link register in order to produce a backtrace. The following patch adds markers of [PAC] to the bracktrace, to indicate which addresses needed unmasking. This includes the backtrace when using MI. For example, consider the following backtrace: (gdb) bt 0 0x0000000000400490 in puts@plt () 1 0x00000000004005dc in foo ("hello") at cbreak-lib.c:6 2 0x0000000000400604 [PAC] in bar () at cbreak-lib.c:12 3 0x0000000000400620 [PAC] in main2 () at cbreak.c:17 4 0x00000000004005b4 in main () at cbreak-3.c:10 The functions in cbreak-lib use pointer auth, which masks the return address to the previous function, causing the addresses of bar (in the library) and main2 (in the main binary) to require unmasking in order to unwind the backtrace. An extra bool is added alongside the prev_pc in the frame structure. At the point at which the link register is unmasked, the AArch64 port calls into frame to sets the bool. This is the most efficient way of doing it. The marker is also added to the python frame printer, which is always printed if set. The marker is not explicitly exposed to the python code. I expect this will potentially cause issues with some tests in the testsuite when Armv8.3 pointer authentication is used. This should be fixed up in the the future once real hardware is available for full testsuite testing. gdb/ChangeLog: * NEWS: Expand the Pointer Authentication entry. * aarch64-tdep.c (aarch64_frame_unmask_address): Rename from this.

2019-08-07ld: use a specific linker script in BPF targetsJose E. Marchesi7-6/+732
This patch makes the elf64bpf emulation to use it's own linker script, based on elf.sc. At the moment, the only change is that the BPF executable doesn't define an entry symbol (BPF programs feature several entry points scattered in several sections.) This is a step towards the goal of generating proper ELF executables that would be loaded by the kernel's libbpf. We are not there yet: BPF "programs" should still be linked with -r. This change removes a warning while linking executables, decreases the number of unsupported tests in the target from 47 to 29, and increases the number of expected passes from 104 to 145.

Several approaches were discussed (mail or irc) to verify the invariants of the GDB help documentation : checking with apropos ., modifying add_cmd to do the check and output a warning, implement maintenance check-doc. A selftest was finally chosen as: * this can be run on demand, including by users if they want to check user defined commands. * it does not interact with the normal behaviour of apropos, define, python, ... (such as output warnings when a user defines a command help that does not respect the doc). * when the selftest runs, it checks the user defined and python defined commands currently defined. gdb/ChangeLog * unittests/help-doc-selftests.c: New file. * Makefile.in: Add the new file.
2019-08-07Make first and last lines of 'command help documentation' consistent.Philippe Waroquiers53-265/+400
With this patch, the help docs now respect 2 invariants: * The first line of a command help is terminated by a '.' character. * The last character of a command help is not a newline character. Note that the changes for the last invariant were done by Tom, as part of : [PATCH] Remove trailing newlines from help text https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html but some occurrences have been re-introduced since then. Some help docs had to be rephrased/restructured to respect the above invariants. Before this patch, print_doc_line was printing the first line of a command help documentation, but stopping at the first '.' or ',' character. This was giving inconsistent results : * The first line of command helps was sometimes '.' terminated, sometimes not. * The first line of command helps was not always designed to be readable/understandable/unambiguous when stopping at the first '.' or ',' character. This e.g. created the following inconsistencies/problems: < catch exception -- Catch Ada exceptions < catch handlers -- Catch Ada exceptions < catch syscall -- Catch system calls by their names < down-silently -- Same as the `down' command while the new help is: > catch exception -- Catch Ada exceptions, when raised. > catch handlers -- Catch Ada exceptions, when handled. > catch syscall -- Catch system calls by their names, groups and/or numbers. > down-silently -- Same as the `down' command, but does not print anything. Also, the command help doc should not be terminated by a newline character, but this was not respected by all commands. The cli-option -OPT framework re-introduced some occurences. So, the -OPT build help framework was changed to not output newlines at the end of %OPTIONS% replacement. This patch changes the help documentations to ensure the 2 invariants given above. It implied to slightly rephrase or restructure some help docs. Based on the above invariants, print_doc_line (called by 'apropos' and 'help' commands to print the first line of a command help) now outputs the full first line of a command help. This all results in a lot of small changes in the produced help docs. There are less code changes than changes in the help docs, as a lot of docs are produced by some code (e.g. the remote packet usage settings). gdb/ChangeLog 2019-08-07 Philippe Waroquiers <philippe.waroquiers@skynet.be> * cli/cli-decode.h (print_doc_line): Add for_value_prefix argument. * cli/cli-decode.c (print_doc_line): Likewise.

2019-08-06[PR build/24886] disable glibc mcheck supportFrank Ch. Eigler13-290/+63
This patch drops gdb's configury support for glibc's mcheck function. It has been observed to cause false abort()s, because it is thread-unsafe yet interposes every malloc/free operation. So if any library transitively used by gdb also uses threads, then these functions can easily corrupt their own checking data. These days, gcc ASAN and valgrind provide high quality checking, and mcheck is apparently itself being slowly deprecated. So, let's stop linking to it. Attached patch drops the autoconf/Makefile machinery for both gdb and gdbserver. No testsuite-visible impact. IMHO not worth mentioning in NEWS.

2019-08-06Clean up source file error reportingTom Tromey2-14/+18
print_source_lines_base reopens the source file every time that a source line is to be printed. However, there's no need to do this so frequently -- it's enough to do it when switching source files, and otherwise rely on the cache. The code seems to try to avoid these multiple opens; at a guess I'd say something just got confused along the way. This patch fixes the problem by reorganizing the code both to make it more clear, and to ensure that reopens only occur when the "last source visited" changes. gdb/ChangeLog 2019-08-06 Tom Tromey <tromey@adacore.com> * source.c (last_source_error): Now bool.

2019-08-06Add file offsets to the source cacheTom Tromey8-192/+228
Currently, gdb stores the number of lines and an array of file offsets for the start of each line in struct symtab. This patch moves this information to the source cache. This has two benefits. First, it allows gdb to read a source file less frequently. Currently, a source file may be read multiple times: once when computing the file offsets, once when highlighting, and then pieces may be read again while printing source lines. With this change, the file is read once for its source text and file offsets; and then perhaps read again if it is evicted from the cache. Second, if multiple symtabs cover the same source file, then this will share the file offsets between them. I'm not sure whether this happens in practice. gdb/ChangeLog 2019-08-06 Tom Tromey <tromey@adacore.com> * annotate.c (annotate_source_line): Use g_source_cache. * source-cache.c (source_cache::get_plain_source_lines): Change parameters.

2019-08-05Increase timeout in gdb.mi/list-thread-groups-available.expSimon Marchi2-4/+16
Running make check-read1 TESTS="gdb.mi/list-thread-groups-available.exp" on my machine results in timeout failures. Running it while having `tail -F testsuite/gdb.log` on the side shows that the test is never really blocked, it is just slow at consuming the large output generated by `-list-thread-groups --available` (which lists all the processes on the system). If I increase the timeout to a large value, the test passes in ~30 seconds (compared to under 1 second normally). Increase the timeout for the particular mi_gdb_test that is long to execute under read1. The new timeout value is a bit arbitrary. The default timeout is 10 seconds, so I set the new timeout to be "old-timeout * 10", so 100 seconds in the typical case. gdb/testsuite/ChangeLog: PR gdb/24863 * gdb.mi/list-thread-groups-available.exp: Increase timeout for -list-thread-groups --available test when running under check-read1.
2019-08-05[gdb/testsuite] Run read1 timeout tests with with_read1_timeout_factorTom de Vries5-33/+73
When running tests with check-read1, we run into some timeouts where the tests are not easy to rewrite using gdb_test_sequence: ...

Fix these by increasing the timeout by a factor 10.

2019-08-05Use _() in calls to build_helpTom Tromey5-10/+17
Currently some code in gdb uses build_help with N_(), like: static const std::string compile_print_help = gdb::option::build_help (N_("\ I believe this is incorrect. The N_ macro is used to mark text that should end up in the message catalog, but which will be translated by a later call to gettext. However, in this case, there is no later call to gettext, so (if gdb had translations), this text would remain untranslated. Instead, I think using the ordinary _() macro is correct here. Translators will have to know to preserve "%OPTIONS%" in the text -- but that seems both unavoidable and fine. Tested by rebuilding as there's not much else to do. gdb/ChangeLog 2019-08-05 Tom Tromey <tromey@adacore.com> * compile/compile.c (_initialize_compile): Use _(), not N_(). * thread.c (_initialize_thread): Use _(), not N_(). * stack.c (_initialize_stack): Use _(), not N_(). * printcmd.c (_initialize_printcmd): Use _(), not N_().

VQ(R)DMLAH and VQ(R)DMLASH MVE instructions. Previously GAS would accept .u32, .u16 and .u8 suffixes to the VQ(R)DMLAH and VQ(R)DMLASH instructions, however the Armv8.1-M Mainline specification states that these functions only have signed variations (.s32, .s16 and .s8 suffixes).
