Improve gdb_tilde_expand logic.
Before this patch, gdb_tilde_expand would use glob(3) in order to expand tilde at the begining of a path. This implementation has limitation when expanding a tilde leading path to a non existing file since glob fails to expand. This patch proposes to use glob only to expand the tilde component of the path and leaves the rest of the path unchanged. This patch is a followup to the following discution: https://sourceware.org/pipermail/gdb-patches/2021-January/174776.html Before the patch: gdb_tilde_expand("~") -> "/home/lsix" gdb_tilde_expand("~/a/c/b") -> error() is called After the patch: gdb_tilde_expand("~") -> "/home/lsix" gdb_tilde_expand("~/a/c/b") -> "/home/lsix/a/c/b" Tested on x84_64 linux. gdb/ChangeLog: * Makefile.in (SELFTESTS_SRCS): Add unittests/gdb_tilde_expand-selftests.c. * unittests/gdb_tilde_expand-selftests.c: New file. gdbsupport/ChangeLog: * gdb_tilde_expand.cc (gdb_tilde_expand): Improve implementation. (gdb_tilde_expand_up): Delegate logic to gdb_tilde_expand. * gdb_tilde_expand.h (gdb_tilde_expand): Update description. |

gmp-utils: protect gdb_mpz exports against out-of-range values
The gdb_mpz class currently provides a couple of methods which
essentially export an mpz_t value into either a buffer, or an integral
type. The export is based on using the mpz_export function which
we discovered can be a bit treacherous if used without caution.
In particular, the initial motivation for this patch was to catch
situations where the mpz_t value was so large that it would not fit
in the destination area. mpz_export does not know the size of
the buffer, and therefore can happily write past the end of our buffer.
While designing a solution to the above problem, I also discovered
that we also needed to be careful when exporting signed numbers.
In particular, numbers which are larger than the maximum value
for a given signed type size, but no so large as to fit in the
*unsigned* version with the same size, would end up being exported
incorrectly. This is related to the fact that mpz_export ignores
the sign of the value being exportd, and assumes an unsigned export.
Thus, for such large values, the appears as if mpz_export is able
to fit our value into our buffer, but in fact, it does not.
Also, I noticed that gdb_mpz::write wasn't taking its unsigned_p
parameter, which was a hole.
For all these reasons, a new low-level private method called
"safe_export" has been added to class gdb_mpz, whose goal is
to perform all necessary checks and manipulations for a safe
and correct export. As a bonus, this method allows us to factorize
the handling of negative value exports.
The gdb_mpz::as_integer and gdb_mpz::write methods are then simplified
to take advantage of this new safe_export method.
gdb/ChangeLog:
* gmp-utils.h (gdb_mpz::safe_export): New private method.
(gdb_mpz::as_integer): Reimplement using gdb_mpz::safe_export.
* gmp-utils.c (gdb_mpz::write): Rewrite using gdb_mpz::safe_export.
(gdb_mpz::safe_export): New method.
* unittests/gmp-utils-selftests .c (gdb_mpz_as_integer):
Update function description.
(check_as_integer_raises_out_of_range_error): New function.
(gdb_mpz_as_integer_out_of_range): New function.

gdb_mpz_as_integer_out_of_range as a selftest.

gmp-utils: Convert the read/write methods to using gdb::array_view
This commit changes the interfaces of some of the methods declared
in gmp-utils to take a gdb::array_view of gdb_byte instead of a
(gdb_byte *, size) couple.
This makes these methods' API probably more C++-idiomatic.
* gmp-utils.h (gdb_mpz::read): Change buf and len parameters
into one single gdb::array_view parameter.
(gdb_mpz::write): Likewise.
(gdb_mpq::read_fixed_point, gdb_mpq::write_fixed_point): Likewise.
* gmp-utils.c (gdb_mpz::read): Change buf and len parameters
into one single gdb::array_view parameter.
Adjust implementation accordingly.
(gdb_mpz::write): Likewise.
(gdb_mpq::read_fixed_point, gdb_mpq::write_fixed_point): Likewise.
* unittests/gmp-utils-selftests.c: Adapt following changes above.
* valarith.c, valops.c, valprint.c, value.c: Likewise.

Fix stack smashing error during gdb_mpq_write_fixed_point selftest
When building GDB using Ubuntu 20.04's system libgmp and compiler,
running the "maintenance selftest" command triggers the following error:
| Running selftest gdb_mpq_write_fixed_point.
| *** stack smashing detected ***: terminated
| [1] 1092790 abort (core dumped) ./gdb gdb
This happens while trying to construct an mpq_t object (a rational)
from two integers representing the numerator and denominator.
In our test, the numerator is -8, and the denominator is 1.
The problem was that the rational was constructed using the wrong
function. This is what we were doing prior to this patch:
mpq_set_ui (v.val, numerator, denominator);
The 'u' in "ui" stands for *unsigned*, which is wrong because
numerator and denominator's type is "int".
As a result of the above, instead of getting a rational value of -8,
we get a rational with a very large positive value (gmp_printf
says "18446744073709551608").
From there, the test performs an operation which is expected to
write this value into a buffer which was not dimensioned to fit
such a number, thus leading GMP into a buffer overflow.
This was verified by applying the formula that GMP's documentation
gives for the required memory buffer size needed during export:
| When an application is allocating space itself the required size can
| be determined with a calculation like the following. Since
| mpz_sizeinbase always returns at least 1, count here will be at
| least one, which avoids any portability problems with malloc(0),
| though if z is zero no space at all is actually needed (or written).
|
| numb = 8*size - nail;
| count = (mpz_sizeinbase (z, 2) + numb-1) / numb;
| p = malloc (count * size);
With the very large number, mpz_sizeinbase returns 66 and thus
the malloc size becomes 16 bytes instead of the 8 we allocated.
This patch fixes the issue by using the correct "set" function.
gdb/ChangeLog:
* unittests/gmp-utils-selftests.c (write_fp_test): Use mpq_set_si
instead of mpq_set_ui to initialize our GMP rational.

gdb: fix unittests/gmp-utils-selftests.c build on solaris
When building on solaris (gcc farm machine gcc211), I get:

The "pow" function overloads only exist for float-like types, and the
compiler doesn't know which one we want. Change "2" for "2.0", which
makes the compiler choose one alternative (the double one, I believe).

gmp-utils: New API to simply use of GMP's integer/rational/float objects
This API was motivated by a number of reasons:
- GMP's API does not handle "long long" and "unsigned long long",
so using LONGEST and ULONGEST is not straightforward;
- Automate the need to initialize GMP objects before use, and
clear them when no longer used.
However, this API grew also to help with similar matter such
as formatting to a string, and also reading/writing fixed-point
values from byte buffers.
Dedicated unit testing is also added.
gdb/ChangeLog:
* gmp-utils.h, gmp-utils.h: New file.
* unittests/gmp-utils-selftests.c: New file.
* Makefile.in (SUBDIR_UNITTESTS_SRCS): Add
unittests/gmp-utils-selftests.c.
(COMMON_SFILES) Add gmp-utils.c.
(HFILES_NO_SRCDIR): Add gmp-utils.h.

gdb, gdbserver, gdbsupport: fix leading space vs tabs issues
Many spots incorrectly use only spaces for indentation (for example, there are a lot of spots in ada-lang.c). I've always found it awkward when I needed to edit one of these spots: do I keep the original wrong indentation, or do I fix it? What if the lines around it are also wrong, do I fix them too? I probably don't want to fix them in the same patch, to avoid adding noise to my patch. So I propose to fix as much as possible once and for all (hopefully). One typical counter argument for this is that it makes code archeology more difficult, because git-blame will show this commit as the last change for these lines. My counter counter argument is: when git-blaming, you often need to do "blame the file at the parent commit" anyway, to go past some other refactor that touched the line you are interested in, but is not the change you are looking for. So you already need a somewhat efficient way to do this. Using some interactive tool, rather than plain git-blame, makes this trivial. For example, I use "tig blame <file>", where going back past the commit that changed the currently selected line is one keystroke. It looks like Magit in Emacs does it too (though I've never used it). Web viewers of Github and Gitlab do it too. My point is that it won't really make archeology more difficult. The other typical counter argument is that it will cause conflicts with existing patches. That's true... but it's a one time cost, and those are not conflicts that are difficult to resolve. I have also tried "git rebase --ignore-whitespace", it seems to work well. Although that will re-introduce the faulty indentation, so one needs to take care of fixing the indentation in the patch after that (which is easy). gdb/ChangeLog: * aarch64-linux-tdep.c: Fix

Tweak gdbsupport/valid-expr.h for GCC 6, fix build
With GCC 6.4 and 6.5 (at least), unit tests that use
gdbsupport/valid-expr.h's CHECK_VALID fail to compile, with:
In file included from src/gdb/unittests/offset-type-selftests.c:24:0:
src/gdb/unittests/offset-type-selftests.c: In substitution of 'template<class Expected, template<class ...> class Op, class ...

src/gdb/unittests/offset-type-selftests.c:75:1: required from here
src/gdb/../gdbsupport/valid-expr.h:65:20: error: type/value mismatch at argument 2 in template parameter list for 'template<class Expected, template<class ...> class Op, class ... Args> using is_detected_exact = std::is_same<Expected, typename gdb::detection_detail::detector<gdb::nonesuch, void, Op, Args ...>::type>'
archetype, TYPES>::value == VALID, \
^
The important part is the "error: type/value mismatch" error. Seems
like that GCC doesn't understand that archetype is an alias template,
and is being strict in requiring a template class.
The fix here is then to make archetype a template class, to pacify
GCC. The resulting code looks like this:
template <TYPENAMES, typename = decltype (EXPR)>
struct archetype
{
};
static_assert (gdb::is_detected_exact<archetype<TYPES, EXPR_TYPE>,
archetype, TYPES>::value == VALID, "");
is_detected_exact<Expected, Op, Args> checks whether Op<Args> is type
Expected:
- For Expected, we pass the explicit EXPR_TYPE, overriding the
default parameter type of archetype.
- For Args we don't pass the last template parameter, so archtype
defaults to the EXPR's decltype.
So in essence, we're really checking whether EXPR_TYPE is the same as
decltype(EXPR).
We need to do the decltype in a template context in order to trigger
SFINAE instead of failing to compile.
The hunk in unittests/enum-flags-selftests.c becomes necessary,
because unlike with the current alias template version, this new
version makes GCC trigger -Wenum-compare warnings as well:
src/gdb/unittests/enum-flags-selftests.c:328:33: error: comparison between 'enum selftests::enum_flags_tests::RE' and 'enum selftests::enum_flags_tests::RE2' [-Werror=enum-compare]

^
src/gdb/../gdbsupport/valid-expr.h:61:45: note: in definition of macro 'CHECK_VALID_EXPR_INT'

^
Build-tested with:
- GCC {4.8.5, 6.4, 6.5, 7.3.1, 9.3.0, 11.0.0-20200910}
- Clang 10.0.0

* valid-expr.h (CHECK_VALID_EXPR_INT): Make archetype a template
class instead of an alias template and adjust static_assert.
gdb/ChangeLog:

Use a curses pad for source and disassembly windows
This changes the TUI source and disassembly windows to use a curses pad for their text. This is an important step toward properly handling non-ASCII characters, because it makes it easy to scroll horizontally without needing gdb to also understand multi-byte character boundaries -- this can be wholly delegated to curses.

Use arrays rather than pointers for global string constants
My understanding is that it's mildly better to use a static const array, as opposed to a "const char *", for a global string constant, when possible. This makes sense to me because the pointer requires a load from an address, whereas the array is just the address. So, I searched for these in gdb and gdbserver. This patch fixes the ones I found. gdb/ChangeLog 2020-09-15 Tom Tromey <tromey@adacore.com> * unittests/memory-map-selftests.c (valid_mem_map): Now array. * ui-style.c (ansi_regex_text): Now array. * rust-exp.y (number_regex_text): Now array. * linespec.c (linespec_quote_characters): Now array. * jit.c (jit_break_name, jit_descriptor_name, reader_init_fn_sym): Now arrays. gdbserver/ChangeLog 2020-09-15 Tom Tromey <tromey@adacore.com> * linux-x86-low.cc (xmltarget_i386_linux_no_xml) (xmltarget_amd64_linux_no_xml): Now arrays. |

Rewrite enum_flags, add unit tests, fix problems
This patch started by adding comprehensive unit tests for enum_flags.
For the testing part, it adds:
- tests of normal expected uses of the API.
- checks that _invalid_ uses of the API would fail to compile. I.e.,
it validates that enum_flags really is a strong type, and that
incorrect mixing of enum types would be caught at compile time. It
pulls that off making use of SFINEA and C++11's decltype/constexpr.
This revealed many holes in the enum_flags API. For example, the f1
assignment below currently incorrectly fails to compile:
enum_flags<flags> f1 = FLAG1;
enum_flags<flags> f2 = FLAG2 | f1;
The unit tests also revealed that this useful use case doesn't work:
enum flag { FLAG1 = 1, FLAG2 = 2 };
enum_flags<flag> src = FLAG1;
enum_flags<flag> f1 = condition ? src : FLAG2;
It fails to compile because enum_flags<flag> and flag are convertible
to each other.
Turns out that making enum_flags be implicitly convertible to the
backing raw enum type was not a good idea.
If we make it convertible to the underlying type instead, we fix that
ternary operator use case, and, we find cases throughout the codebase
that should be using the enum_flags but were using the raw backing
enum instead. So it's a good change overall.
Also, several operators were missing.
These holes and more are plugged by this patch, by reworking how the
enum_flags operators are implemented, and making use of C++11's
feature of being able to delete methods/functions.
There are cases in gdb/compile/ where we need to call a function in a
C plugin API that expects the raw enum. To address cases like that,
this adds a "raw()" method to enum_flags. This way we can keep using
the safer enum_flags to construct the value, and then be explicit when
we need to get at the raw enum.
This makes most of the enum_flags operators constexpr. Beyond
enabling more compiler optimizations and enabling the new unit tests,
this has other advantages, like making it possible to use operator|
with enum_flags values in switch cases, where only compile-time
constants are allowed:
enum_flags<flags> f = FLAG1 | FLAG2;
switch (f)
{
case FLAG1 | FLAG2:
break;
}
Currently that fails to compile.
It also switches to a different mechanism of enabling the global
operators. The current mechanism isn't namespace friendly, the new
one is.
It also switches to C++11-style SFINAE -- instead of wrapping the
return type in a SFINAE-friently structure, we use an unnamed template
parameter. I.e., this:
template <typename enum_type,
typename = is_enum_flags_enum_type_t<enum_type>>
enum_type
operator& (enum_type e1, enum_type e2)
instead of:
template <typename enum_type>
typename enum_flags_type<enum_type>::type
operator& (enum_type e1, enum_type e2)
Note that the static_assert inside operator~() was converted to a
couple overloads (signed vs unsigned), because static_assert is too
late for SFINAE-based tests, which is important for the CHECK_VALID
unit tests.
Tested with gcc {4.8, 7.1, 9.3} and clang {5.0.2, 10.0.0}.

Add a selftest that detects a 'corrupted' command tree structure in GDB.
The GDB data structure that records the GDB commands is made of 'struct cmd_list_element' defined in cli-decode.h. A cmd_list_element has various pointers to other cmd_list_element structures, All these pointers are together building a graph of commands. However, when following the 'next' and '*prefixlist' pointers of cmd_list_element, the structure must better be a tree. If such pointers do not form a tree, then some other elements of cmd_list_element cannot get a correct semantic. In particular, the prefixname has no correct meaning if the same prefix command can be reached via 2 different paths. This commit introduces a selftest that detects (at least some cases of) errors leading to 'next' and '*prefixlist' not giving a tree structure. The new 'command_structure_invariants' selftest detects one single case where the command structure is not a tree: (gdb) maintenance selftest command_structure_invariants Running selftest command_structure_invariants. list 0x56362e204b98 duplicated, reachable via prefix 'show ' and 'info set '. Duplicated list first command is 'ada' Self test failed: self-test failed at ../../classfix/gdb/unittests/command-def-selftests.c:160 Ran 1 unit tests, 1 failed (gdb) This was fixed by the previous commit. 2020-05-15 Philippe Waroquiers <philippe.waroquiers@skynet.be> * unittests/help-doc-selftests.c: Rename to unittests/command-def-selftests.c * unittests/command-def-selftests.c (help_doc_tests): Update some comments.

Compare iterators, not values, in filtered_iterator::operator{==,!=}
The == and != operators on filtered_iterator are not doing the right thing, they compare values pointed by the wrapped iterators instead of comparing the iterators themselves. As a result, operator== will return true if the two iterators point to two equal values at different positions. operator!= will fail similarly. Also, this causes it to deference past-the-end iterators when doing. For example, in for (iter = ...; iter != end_iter; ++iter) the != comparison dereferences end_iter. I don't think this should happen. I don't think it's a problem today, given that we only use filtered_iterator to wrap linked lists of threads and inferiors. Dereferencing past-the-end iterators of these types is not fatal, it just returns NULL, which is not a value we otherwise find in the lists. But in other contexts, it could become problematic. I have added a simple self test that fails without the fix applied. gdb/ChangeLog: * filtered-iterator.h (filtered_iterator) <operator==, operator!=>: Compare wrapped iterators, not wrapped pointers. * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/filtered_iterator-selftests.c. * unittests/filtered_iterator-selftests.c: New file. |

Fix another build failure in tui-selftests.c
Christian had emailed me to say that the TUI unit test broke the mingw build, but I erroneously thought this was fixed by the earlier patch that made the test body conditional on the TUI being built. However, I was wrong about this -- tui-selftests.c unconditionally includes tui-winsource.h, which fails if curses is not available.

Handle %I64d in format_pieces
We found a bug internally where gdb would crash while disassembling a certain instruction. This was tracked down to the handling of %I64d in format_pieces. format_pieces will convert %ll to %I64d on mingw -- so format_pieces should also handle parsing this format. In this patch, I've made the parsing unconditional, since I think it is harmless to accept extra formats. I've also taken the opportunity to convert the length modifier test to a "switch". Tested internally using our failing test case. gdb/ChangeLog 2019-11-21 Tom Tromey <tromey@adacore.com> * gdbsupport/format.c (format_pieces): Parse %I64d. * unittests/format_pieces-selftests.c (test_windows_formats): New function. (run_tests): Call it. Change-Id: If335c7c2fc8d01e629cd55182394a483334d79c7 |

I think gcc is just trying to be nice and recommends the good practice
of providing a copy constructor if an assignment operator is provided.
Silence the warning by providing that copy constructor.
gdb/ChangeLog:
* unittests/vec-utils-selftests.c (unordered_remove_tests::obj):
Provide explicit default and copy constructor.

gdb: Support printf 'z' size modifier
The gdb format mechanism doesn't currently support the 'z' size modifier, there are a few places in GDB where this is used. Instead of removing these uses lets just add support to GDB for using 'z'. I found this issue when trying to use some of the debug output. Before this commit: (gdb) set debug dwarf-line 9 (gdb) file test Reading symbols from test... Unrecognized format specifier 'z' in printf (No debugging symbols found in test) (gdb) After this commit: (gdb) set debug dwarf-line 9 (gdb) file test Reading symbols from test... Adding dir 1: /usr/include Adding file 1: test.c Adding file 2: stdc-predef.h Processing actual line 3: file 1, address 0x4004a0, is_stmt 1, discrim 0 Processing actual line 4: file 1, address 0x4004a0, is_stmt 1, discrim 0 .... lots of debug output ... Processing actual line 10: file 1, address 0x4003b7, is_stmt 0, discrim 0 (gdb) I've added a self test to cover the integer format size modifiers, including the 'z' modifier. gdb/ChangeLog: * gdbsupport/format.c (format_pieces::format_pieces): Support printf 'z' size modifier. * gdbsupport/format.h (enum argclass): Add size_t_arg. * printcmd.c (ui_printf): Handle size_t_arg. * ui-out.c (ui_out::vmessage): Likewise. * unittests/format_pieces-selftests.c (test_format_int_sizes): New function.

gdb_vecs.h: Avoid self move assign
While working on another patch I ran into an issue with unordered_remove (in gdb_vecs.h), where removing the last item of the vector can cause a self move assign. When compiling the C++ standard library in debug mode (with -D_GLIBCXX_DEBUG=1) this causes an error to trigger. I've fixed the issue in this patch and provided a unit test. The provided unit test includes an assignment operator which checks for self move assign, this removes the need to compile with -D_GLIBCXX_DEBUG=1 in order to spot the bug. If you're keen to see the error reported from the C++ standard library then remove operator= from the unit test and recompile GDB with -D_GLIBCXX_DEBUG=1. gdb/ChangeLog: * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add new file to the list. * unittests/vec-utils-selftests.c: New file. * gdbsupport/gdb_vecs.h (unordered_remove): Avoid self move assign.

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.

Add a selftest that checks documentation invariants.
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.

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.

Delete parse_flags/parse_flags_qcs
Now that "thread/frame apply" have been converted to the gdb::option framework, these functions are no longer used. For a while, I thought about keeping the unit tests, by making a local version of parse_flags_qcs in the unit tests file. But all that would really test that is used by GDB itself, is the validate_flags_qcs function. So in the end, I went through all the unit tests, and converted any that wasn't already covered to gdb.base/options.exp tests. And those have all already been added in previous patches. gdb/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * cli/cli-utils.c (parse_flags, parse_flags_qcs): Delete. * cli/cli-utils.h (parse_flags, parse_flags_qcs): Delete. * unittests/cli-utils-selftests.c (test_parse_flags) (test_parse_flags_qcs): Delete. (test_cli_utils): Don't call deleted functions. |

On MS-Windows, define _WIN32_WINNT in a single common place.
This changeset defines _WIN32_WINNT to at least 0x0501, the level of Windows XP, unless defined to a higher level, in a single place. It then removes all the overrides of _WIN32_WINNT in individual files as no longer needed. Doing this also solves compilation of windows-nat.c with mingw.org's MinGW, as that file uses CONSOLE_FONT_INFO which needs the XP level to become exposed in the Windows headers, while mingw.org defaults to Windows 9X. gdb/ChangeLog: 2019-05-03 Eli Zaretskii <eliz@gnu.org> * common/common-defs.h [__MINGW32__ || __CYGWIN__]: Define _WIN32_WINNT to the XP level, unless already defined to a higher level. * unittests/parse-connection-spec-selftests.c: * ser-tcp.c: * common/netstuff.c [USE_WIN32API]: Remove the _WIN32_WINNT override. gdb/gdbserver/ChangeLog: 2019-05-03 Eli Zaretskii <eliz@gnu.org> * remote-utils.c: * gdbreplay.c [USE_WIN32API]: Remove the _WIN32_WINNT override. |

Rename gdb exception types

Make exceptions use std::string and be self-managing

Add a new function child_path.
child_path returns a pointer to the first component in a child path that comes after a parent path. This does not depend on trying to stat() the paths since they may describe remote paths but instead relies on filename parsing. The function requires that the child path describe a filename that contains at least one component below the parent path and returns a pointer to the first component. gdb/ChangeLog: * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/child-path-selftests.c. * common/pathstuff.c (child_path): New function. * common/pathstuff.h (child_path): New prototype. * unittests/child-path-selftests.c: New file. |

Fix year range in unittests/.../char/empty.cc copyright header
The year range in the copyright header of that file was incorrect:
// Copyright (C) 3 Free Software Foundation, Inc.
Tracing the origin of this file down, I found that it was copied
from GCC's libstdc++-v3 testsuite:
Adapt and integrate string_view tests
https://www.sourceware.org/ml/gdb-patches/2018-04/msg00113.html
Looking at the version in GCC, I found the same issue, so sent
a fix there:
https://gcc.gnu.org/ml/gcc-patches/2019-01/msg00000.html
Now that the fix is in GCC, this commit applies the same fix
to our copy.
gdb/ChangeLog:
* unittests/basic_string_view/element_access/char/empty.cc:
Fix year range in copyright header.

Update copyright year range in all GDB files.
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. |

Introduce ui_file_style
This introduces the new ui_file_style class and various helpers. This class represents a terminal style and provides methods for parsing and emitting the corresponding ANSI terminal escape sequences. gdb/ChangeLog 2018-12-28 Tom Tromey <tom@tromey.com> * unittests/style-selftests.c: New file. * ui-style.c: New file. * ui-style.h: New file. * ui-file.h: Include ui-style.h. * Makefile.in (COMMON_SFILES): Add ui-style.c. (HFILES_NO_SRCDIR): Add ui-style.h. (SUBDIR_UNITTESTS_SRCS): Add style-selftests.c. |

Fix compile error with clang 3.8
When compiling with clang 3.8 (default clang version on Debian
Stretch, the current stable), we get errors like this:
CXX dtrace-probe.o
../../binutils-gdb/gdb/dtrace-probe.c:103:31: error: default initialization of an object of const type 'const dtrace_static_probe_ops' without a user-provided default constructor
const dtrace_static_probe_ops dtrace_static_probe_ops;
^
Silence them by value-initializing those objects. It's not necessary
with other compilers (later clang versions, gcc), but it shouldn't
hurt either.

invoke_xmethod & array_view
This replaces more pointer+length with gdb::array_view. This time, around invoke_xmethod, and then propagating the fallout around, which inevitably leaks to the overload resolution code. There are several places in the code that want to grab a slice of an array, by advancing the array pointer, and decreasing the length pointer. This patch introduces a pair of new gdb::array_view::slice(...) methods to make that convenient and clear. Unit test included. gdb/ChangeLog: 2018-11-21 Pedro Alves <palves@redhat.com> * common/array-view.h (array_view::splice(size_type, size_t)): New. (array_view::splice(size_type)): New. * eval.c (eval_call, evaluate_funcall): Adjust to use array_view. * extension.c (xmethod_worker::get_arg_types): Adjust to return an std::vector.

Use gdb:array_view in call_function_by_hand & friends
This replaces a few uses of pointer+length with gdb::array_view, in call_function_by_hand and related code. Unfortunately, due to -Wnarrowing, there are places where we can't brace-initialize an gdb::array_view without an ugly-ish cast. To avoid the cast, this patch introduces a gdb::make_array_view function. Unit tests included. This patch in isolation may not look so interesting, due to gdb::make_array_view uses, but I think it's still worth it. Some of the gdb::make_array_view calls disappear down the series, and others could be eliminated with more (non-trivial) gdb::array_view detangling/conversion (e.g. code around eval_call). See this as a "we have to start somewhere" patch. gdb/ChangeLog: 2018-11-21 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_evaluate_subexp): Adjust to pass an array_view. * common/array-view.h (make_array_view): New. * compile/compile-object-run.c (compile_object_run): Adjust to pass an array_view. * elfread.c (elf_gnu_ifunc_resolve_addr): Adjust. * eval.c (eval_call): Adjust to pass an array_view.
