Use libxxhash for hashing, if present
XXHash is faster than htab_hash_string: ------------------------------------------------------------ Benchmark Time CPU Iterations ------------------------------------------------------------ BM_xxh3 11 ns 11 ns 65887249 BM_xxh32 19 ns 19 ns 36511877 BM_xxh64 16 ns 16 ns 42964585 BM_hash_string 182 ns 182 ns 3853125 BM_iterative_hash 77 ns 77 ns 9087638 Unfortunately, XXH3 is still experimental (see https://github.com/Cyan4973/xxHash#user-content-new-experimental-hash-algorithm) However, regular XXH64 is still a lot faster than htab_hash_string per my benchmark above. I used the following string for the benchmark: static constexpr char str[] = "_ZZZL13make_gdb_typeP7gdbarchP10tdesc_typeEN16gdb_type_creator19make_gdb_type_flagsEPK22tdesc_type_with_fieldsE19__PRETTY_FUNCTION__"; htab_hash_string is currently 4.35% + 7.98% (rehashing) of gdb startup when attaching to Chrome's content_shell. An additional 5.21% is spent in msymbol_hash, which does not use this hash function. Unfortunately, since it has to lowercase the string, it can't use this hash function. BM_msymbol_hash 52 ns 52 ns 13281495 It may be worth investigating if strlen+XXHash is still faster than htab_hash_string, which would make it easier to use in more places. Debian ships xxhash as libxxhash{0,-dev}. Fedora ships it as xxhash-devel. gdb/ChangeLog: 2019-10-22 Christian Biesinger <cbiesinger@google.com> * Makefile.in: Link with libxxhash. * config.in: Regenerate. * configure: Regenerate. * configure.ac: Search for libxxhash. * utils.c (fast_hash): Use xxhash if present.

Add a fast_hash function in common-utils
Also updates a caller in symtab.c.

Introduce gdb-specific %p format suffixes
This introduces a few gdb-specific %p format suffixes. This is useful for emitting gdb-specific output in an ergonomic way. It also yields code that is more i18n-friendly. The comment before ui_out::message explains the details. Note that the tests had to change a little. When using one of the gdb printf functions with styling, there can be spurious style changes emitted to the output. This did not seem worthwhile to fix, as the low-level output functions are rather spaghetti-ish already, and I didn't want to make them even worse. This change also necessitated adding support for "*" as precision and width in format_pieces. These are used in various spots in gdb, and it seemed better to me to implement them than to remove the uses. gdb/ChangeLog 2019-10-01 Pedro Alves <palves@redhat.com> Tom Tromey <tom@tromey.com> * unittests/format_pieces-selftests.c: Add gdb_format parameter.

Don't include gdbarch.h from defs.h
I touched symtab.h and was surprised to see how many files were rebuilt. I looked into it a bit, and found that defs.h includes gdbarch.h, which in turn includes many things. gdbarch.h is only needed by a minority ofthe files in gdb, so this patch removes the include from defs.h and updates the fallout. I did "wc -l" on the files in build/gdb/.deps; this patch reduces the line count from 139935 to 137030; so there are definitely future build-time savings here. Note that while I configured with --enable-targets=all, it's possible that some *-nat.c file needs an update. I could not test all of these. The buildbot caught a few problems along these lines. gdb/ChangeLog 2019-07-10 Tom Tromey <tom@tromey.com> * defs.h: Don't include gdbarch.h. * aarch64-ravenscar-thread.c, aarch64-tdep.c, alpha-bsd-tdep.h, alpha-linux-tdep.c, alpha-mdebug-tdep.c, arch-utils.h, arm-tdep.h, ax-general.c, btrace.c, buildsym-legacy.c, buildsym.h, c-lang.c, cli/cli-decode.h, cli/cli-dump.c, cli/cli-script.h, cli/cli-style.h, coff-pe-read.h, compile/compile-c-support.c, compile/compile-cplus.h, compile/compile-loc2c.c, corefile.c, cp-valprint.c, cris-linux-tdep.c, ctf.c, d-lang.c, d-namespace.c, dcache.c, dicos-tdep.c, dictionary.c, disasm-selftests.c, dummy-frame.c, dummy-frame.h, dwarf2-frame-tailcall.c, dwarf2expr.c, expression.h, f-lang.c, frame-base.c, frame-unwind.c, frv-linux-tdep.c, gdbarch-selftests.c, gdbtypes.h, go-lang.c, hppa-nbsd-tdep.c, hppa-obsd-tdep.c, i386-dicos-tdep.c, i386-tdep.h, ia64-vms-tdep.c, interps.h, language.c, linux-record.c, location.h, m2-lang.c, m32r-linux-tdep.c, mem-break.c, memattr.c, mn10300-linux-tdep.c, nios2-linux-tdep.c, objfiles.h, opencl-lang.c, or1k-linux-tdep.c, p-lang.c, parser-defs.h, ppc-tdep.h, probe.h, python/py-record-btrace.c, record-btrace.c, record.h, regcache-dump.c, regcache.h, riscv-fbsd-tdep.c, riscv-linux-tdep.c, rust-exp.y, sh-linux-tdep.c, sh-nbsd-tdep.c, source-cache.c, sparc-nbsd-tdep.c, sparc-obsd-tdep.c, sparc-ravenscar-thread.c, sparc64-fbsd-tdep.c, std-regs.c, target-descriptions.h, target-float.c, tic6x-linux-tdep.c, tilegx-linux-tdep.c, top.c, tracefile.c, trad-frame.c, type-stack.h, ui-style.c, utils.c, utils.h, valarith.c, valprint.c, varobj.c, x86-tdep.c, xml-support.h, xtensa-linux-tdep.c, cli/cli-cmds.h: Update. * s390-linux-nat.c, procfs.c, inf-ptrace.c: Likewise. |

Rename common to gdbsupport
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty.

Add highlight style, title style, fputs_highlighted. Improve 'show style'
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. |

Have 'thread|frame apply' style their output.
'thread|frame apply CMD' launches CMD so that CMD output goes to a string_file. This patch ensures that string_file for such CMD output contains style escape sequences that 'thread|frame apply' will later on output on the real terminal, so as to have CMD output properly styled. The idea is to have the class ui_file having overridable methods to indicate that the output to this ui_file should be done using 'terminal' behaviour such as styling. Then these methods are overriden in string_file so that a specially constructed string_file will get output with style escape sequences. After this patch, the output of CMD by thread|frame apply CMD is styled similarly as when CMD is launched directly. Note that string_file (term_out true) could also support wrapping, but this is not done (yet?).

Add output styles to gdb
This adds some output styling to the CLI. A style is currently a foreground color, a background color, and an intensity (dim or bold). (This list could be expanded depending on terminal capabilities.) A style can be applied while printing. For ui-out, this is done by passing the style constant as an argument. For low-level cases, fprintf_styled and fputs_styled are provided. Users can control the style via a number of new set/show commands. In the interest of not typing many nearly-identical documentation strings, I automated this. On the down side, this is not very i18n-friendly. I've chose some default colors to use. I think it would be good to enable this by default, so that when users start the new gdb, they will see the new feature. Stylizing is done if TERM is set and is not "dumb". This could be improved when the TUI is available by using the curses has_colors call. That is, the lowest layer could call this without committing to using curses everywhere; see my other patch for TUI colorizing. I considered adding a new "set_style" method to ui_file. However, because the implementation had to interact with the pager code, I didn't take this approach. But, one idea might be to put the isatty check there and then have it defer to the lower layers. gdb/ChangeLog 2018-12-28 Tom Tromey <tom@tromey.com> * utils.h (set_output_style, fprintf_styled) (fputs_styled): Declare. * utils.c (applied_style, desired_style): New globals.

aarch64: PR 19806: watchpoints: false negatives + PR 20207 contiguous ones
Some unaligned watchpoints were currently missed. On old kernels as specified in kernel RFE: aarch64: ptrace: BAS: Support any contiguous range (edit) https://sourceware.org/bugzilla/show_bug.cgi?id=20207 after this patch some other unaligned watchpoints will get reported as false positives. With new kernels all the watchpoints should work exactly. There may be a regresion that it now less merges watchpoints so that with multiple overlapping watchpoints it may run out of the 4 hardware watchpoint registers. But as discussed in the original thread GDB needs some generic watchpoints merging framework to be used by all the target specific code. Even current FSF GDB code does not merge it perfectly. Also with the more precise watchpoints one can technically merge them less. And I do not think it matters too much to improve mergeability only for old kernels. Still even on new kernels some better merging logic would make sense. There remains one issue: kernel-4.15.14-300.fc27.armv7hl FAIL: gdb.base/watchpoint-unaligned.exp: continue FAIL: gdb.base/watchpoint-unaligned.exp: continue (gdb) continue Continuing. Unexpected error setting watchpoint: Invalid argument. (gdb) FAIL: gdb.base/watchpoint-unaligned.exp: continue But that looks as a kernel bug to me. (1) It is not a regression by this patch.

Implement write_async_safe for mi_console_file (PR 22299)
Enabling "set debug lin-lwp 1" with the MI interpreter doesn't work. When the sigchld_handler function wants to print a debug output ("sigchld\n"), it uses ui_file_write_async_safe. This ends up in the default implementation of ui_file::write_async_safe, which aborts GDB. This patch implements the write_async_safe method for mi_console_file. The "normal" MI output is line buffered, which means the output accumulates in m_buffer until a \n is written, at which point it's flushed in m_raw. The implementation of write_async_safe provided by this patch bypasses this buffer and writes directly to m_raw. There are two reasons for this: (1) Appending to m_buffer (therefore to an std::string) is probably not async-safe, as it may allocate memory. (2) We may have a partial output already in m_buffer, so that would lead to some nested MI output, not so great. There is probably still a chance to have bad MI output, if sigchld_handler is invoked in the middle of mi_console_file's flush, and the line being flushed is only partially sent to m_raw. The solution would probably be to block signals during flushing. Since this is only used for debug output, I don't know if it's worth the effort to do that. To implement write_async_safe, I needed to use the fputstrn_unfiltered, which does the necessary escaping (e.g. replace \n with \\n). I started by adding printchar's callback parameters to fputstrn_unfiltered, to be able to pass async-safe versions of them. It's not easy to provide an async-safe version of do_fprintf, but it turns out that we can easily replace printchar's callbacks with a single do_fputc quite easily. The async-safe version of do_fputc simply calls the underlying ui_file's write_async_safe method. gdb/ChangeLog: PR mi/22299 * mi/mi-console.c (do_fputc_async_safe): New.

Change streq to return bool
I wanted to use streq with std::unique in another (upcoming) patch in this seres, so I changed it to return bool. To my surprise, this lead to regressions. The cause turned out to be that streq was used as an htab callback -- by casting it to the correct function type. This sort of cast is invalid, so this patch adds a variant which is directly suitable for use by htab. (Note that I did not add an overload, as I could not get that to work with template deduction in the other patch.)

Create new common/pathstuff.[ch]
This commit moves the path manipulation routines found on utils.c to a new common/pathstuff.c, and updates the Makefile.in's accordingly. The routines moved are "gdb_realpath", "gdb_realpath_keepfile" and "gdb_abspath". This will be needed because gdbserver will have to call "gdb_abspath" on my next patch, which implements a way to expand the path of the inferior provided by the user in order to allow specifying just the binary name when starting gdbserver, like: $ gdbserver :1234 a.out With the recent addition of the startup-with-shell feature on gdbserver, this scenario doesn't work anymore if the user doesn't have the current directory listed in the PATH variable. I had to do a minor adjustment on "gdb_abspath" because we don't have access to "tilde_expand" on gdbserver, so now the function is using "gdb_tilde_expand" instead. Otherwise, the code is the same. Regression tested on the BuildBot, without regressions. gdb/ChangeLog: 2018-02-28 Sergio Durigan Junior <sergiodj@redhat.com> * Makefile.in (COMMON_SFILES): Add "common/pathstuff.c". (HFILES_NO_SRCDIR): Add "common/pathstuff.h". * auto-load.c: Include "common/pathstuff.h". * common/common-def.h (current_directory): Move here. * common/gdb_tilde_expand.c (gdb_tilde_expand_up): New function. * common/gdb_tilde_expand.h (gdb_tilde_expand_up): New prototype. * common/pathstuff.c: New file. * common/pathstuff.h: New file. * compile/compile.c: Include "common/pathstuff.h". * defs.h (current_directory): Move to "common/common-defs.h". * dwarf2read.c: Include "common/pathstuff.h". * exec.c: Likewise. * guile/scm-safe-call.c: Likewise. * linux-thread-db.c: Likewise. * main.c: Likewise. * nto-tdep.c: Likewise. * objfiles.c: Likewise. * source.c: Likewise. * symtab.c: Likewise. * utils.c: Include "common/pathstuff.h".

Clear non-significant bits of address on memory access
ARMv8 supports tagged address, that is, the top one byte in address is ignored. It is always enabled on aarch64-linux. See https://www.kernel.org/doc/Documentation/arm64/tagged-pointers.txt The tag in the tagged address is modeled as non-significant bits in address, so this patch adds a new gdbarch method significant_addr_bit and clear the non-significant bits (the top byte in ARMv8) of the virtual address at the point before passing address to target cache layer. IOW, the address used in the target cache layer is already cleared. Before this patch, (gdb) x/x 0x0000000000411030 0x411030 <global>: 0x00000000 (gdb) x/x 0xf000000000411030 0xf000000000411030: Cannot access memory at address 0xf000000000411030 After this patch, (gdb) x/x 0x0000000000411030 0x411030 <global>: 0x00000000 (gdb) x/x 0xf000000000411030 0xf000000000411030: 0x00000000 Note that I used address_significant in paddress, but it causes a regression gdb.base/long_long.exp, because gdb clears the non-significant bits in address, but test still expects them. p/a val.oct^M $24 = 0x2ee53977053977^M (gdb) FAIL: gdb.base/long_long.exp: p/a val.oct so I defer the change there. gdb: 2017-12-08 Yao Qi <yao.qi@linaro.org> * aarch64-tdep.c (aarch64_gdbarch_init): Install gdbarch significant_addr_bit. * gdbarch.sh (significant_addr_bit): New. * gdbarch.c, gdbarch.h: Re-generated. * target.c (memory_xfer_partial): Call address_significant. * utils.c (address_significant): New function. * utils.h (address_significant): Declare. 2017-12-08 Yao Qi <yao.qi@linaro.org> gdb/testsuite: * gdb.arch/aarch64-tagged-pointer.c: New file. * gdb.arch/aarch64-tagged-pointer.exp: New file. |

Breakpoints in symbols with ABI tags (PR c++/19436)
Trying to set a breakpoint in a function with an ABI tag does not work currently. E.g., debugging gdb itself, we see this with the "string_printf" function: (top-gdb) b string_print [TAB] (top-gdb) b string_printf[abi:cxx11](char const*, ...) [RET] No source file named string_printf[abi. Make breakpoint pending on future shared library load? (y or [n]) Quoting doesn't help: (top-gdb) b 'string_printf[abi:cxx11]'(char const*, ...) malformed linespec error: unexpected string, "(char const*, ...)" (top-gdb) b 'string_printf[abi:cxx11](char const*, ...)' No source file named string_printf[abi. Make breakpoint pending on future shared library load? (y or [n]) n This patch fixes this, and takes it a bit further. The actual symbol name as demangled by libiberty's demangler is really string_printf[abi:cxx11](char const*, ...) however, this patch makes it possible to set the breakpoint with string_printf(char const*, ...) too. I.e., ignoring the ABI tag. And to match, it teaches the completer to complete the symbol name without the ABI tag, i.e., "string_pri<TAB>" -> "string_printf(char const*, ...)" If however, you really want to break on a symbol with the tag, then you simply start writing the tag, and GDB will preserve it, like: "string_printf[a<TAB>" -> "string_printf[abi:cxx11](char const*, ...)"

Make strcmp_iw NOT ignore whitespace in the middle of tokens
currently "b func tion" manages to set a breakpoint at "function" ! All these years I had never noticed this, but now that the linespec completer actually works, this easily happens by accident, with: "b func t<tab>" expecting to get "thread", but getting instead: "b func tion" ... Also, this: "b rettypefunc<int>" manages to set a breakpoint on "rettype func<int>()". These things happen due to strcmp_iw "magic". Fix it by teaching strcmp_iw about when can it skip whitespace. This required handling user-defined operators, and scope operators, complicating the code a bit, unfortunately. I added unit tests for all the corner cases I stumbled on, as I was developing this, and then in the end wrote a testsuite testcase covering many of the same things and more (to be added later). gdb/ChangeLog: 2017-11-24 Pedro Alves <palves@redhat.com> * cp-support.c (cp_symbol_name_matches_1): New, factored out from cp_fq_symbol_name_matches.

Introduce lookup_name_info and generalize Ada's FULL/WILD name matching
Summary: - This is preparation for supporting wild name matching on C++ too. - This is also preparation for TAB-completion fixes. - Makes symbol name matching (think strcmp_iw) be based on a per-language method. - Merges completion and non-completion name comparison (think language_ops::la_get_symbol_name_cmp generalized). - Avoid re-hashing lookup name multiple times - Centralizes preparing a name for lookup (Ada name encoding / C++ Demangling), both completion and non-completion. - Fixes Ada latent bug with verbatim name matches in expressions - Makes ada-lang.c use common|symtab.c completion code a bit more. Ada's wild matching basically means that "(gdb) break foo" will find all methods named "foo" in all packages. Translating to C++, it's roughly the same as saying that "break klass::method" sets breakpoints on all "klass::method" methods of all classes, no matter the namespace. A following patch will teach GDB about fullname vs wild matching for C++ too. This patch is preparatory work to get there. Another idea here is to do symbol name matching based on the symbol language's algorithm. I.e., avoid dependency on current language set. This allows for example doing (gdb) b foo::bar< int > (<tab> and having gdb name match the C++ symbols correctly even if the current language is C or Assembly (or Rust, or Ada, or ...), which can easily happen if you step into an Assembly/C runtime library frame. By encapsulating all the information related to a lookup name in a class, we can also cache hash computation for a given language in the lookup name object, to avoid recomputing it over and over. Similarly, because we don't really know upfront which languages the lookup name will be matched against, for each language we store the lookup name transformed into a search name. E.g., for C++, that means demangling the name. But for Ada, it means encoding the name. This actually forces us to centralize all the different lookup name encoding in a central place, resulting in clearer code, IMO. See e.g., the new ada_lookup_name_info class. The lookup name -> symbol search name computation is also done only once per language. The old language->la_get_symbol_name_cmp / symbol_name_cmp_ftype are generalized to work with both completion, and normal symbol look up. At some point early on, I had separate completion vs non-completion language vector entry points, but a single method ends up being better IMO for simplifying things -- the more we merge the completion / non-completion name lookup code paths, the less changes for bugs causing completion vs normal lookup finding different symbols. The ada-lex.l change is necessary because when doing (gdb) p <UpperCase> then the name that is passed to write_ write_var_or_type -> ada_lookup_symbol_list misses the "<>", i.e., it's just "UpperCase", and we end up doing a wild match against "UpperCase" lowercased by ada_lookup_name_info's constructor. I.e., "uppercase" wouldn't ever match "UpperCase", and the symbol lookup fails. This wouldn't cause any regression in the testsuite, but I added a new test that would pass before the patch and fail after, if it weren't for that fix. This is latent bug that happens to go unnoticed because that particular path was inconsistent with the rest of Ada symbol lookup by not lowercasing the lookup name. Ada's symbol_completion_add is deleted, replaced by using common code's completion_list_add_name. To make the latter work for Ada, we needed to add a new output parameter, because Ada wants to return back a custom completion candidates that are not the symbol name. With this patch, minimal symbol demangled name hashing is made consistent with regular symbol hashing. I.e., it now goes via the language vector's search_name_hash method too, as I had suggested in a previous patch. dw2_expand_symtabs_matching / .gdb_index symbol names were a challenge. The problem is that we have no way to telling what is the language of each symbol name found in the index, until we expand the corresponding full symbol, which is off course what we're trying to avoid. Language information is simply not considered in the index format... Since the symbol name hashing and comparison routines are per-language, we now have a problem. The patch sorts this out by matching each name against all languages. This is inneficient, and indeed slows down completion several times. E.g., with: $ cat script.cmd set pagination off set $count = 0 while $count < 400 complete b string_prin printf "count = %d\n", $count set $count = $count + 1 end $ time gdb --batch -q ./gdb-with-index -ex "source script-string_printf.cmd" I get, before patch (-O2, x86-64): real 0m1.773s user 0m1.737s sys 0m0.040s While after patch (-O2, x86-64): real 0m9.843s user 0m9.482s sys 0m0.034s However, the following patch will optimize this, and will actually make this use case faster compared to the "before patch" above: real 0m1.321s user 0m1.285s sys 0m0.039s gdb/ChangeLog: 2017-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_encode): Rename to ..

Make language_def O(1)
Profiling GDB with the rest of series applied, I saw calls to language_def showing up high in some runs. The problem is that language_def is O(N) currently, since walk the languages vector each time to find the matching language_defn. IMO, the add_language mechanism is pointless, because "enum language" implies the core of GDB needs to know about all languages anyway. So simply make the languages vector array be an array where each element's index is the corresponding enum language enumerator. Note that "local_language_defn" is gone along the way. It's just a copy of "auto", so the new code simply maps one to the other. One fewer place to update when we need to change the language vector... Also, a while ago the output of "set language" was made out of order as side effect of some other change. While I was at it, I made them sorted again. gdb/ChangeLog: 2017-07-20 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_language_defn): Make extern.
