I noticed that elfread.c always allocates a dbx_symfile_info, even
though this is only ever needed in the unusual case of reading stabs
in ELF.
This patch moves the allocation into dbxread.c, and applies the same
treatment to similar code in coffread.c.
Regression tested on x86-64 Fedora 29.

DW_AT_main_subprogram is supported in normal mode in read_partial_die, but not
in -readnow mode.
Fix this by adding support for DW_AT_main_subprogram in read_func_scope.
Tested on x86_64-linux with native and RFC target board readnow (
https://sourceware.org/ml/gdb-patches/2019-05/msg00073.html ).

Mention in the description of the `-rpath' LD option the restrictions
the option has with respect to searching link-time dependencies of
shared objects referred in the link. Previously these restrictions were
only documented along with the `-rpath-link' option, which may not be
the place one would consider when looking for the semantics of `-rpath'.
Copy the relevant part of the `-rpath-link' option description then,
splitting the now overlong paragraph into three, for legibility.
ld/
* ld.texi (Options): Also document `-rpath' option restrictions
in the description of the option itself.

Not all platforms have it. Use libiberty xstrndup() instead.
(The include of libiberty.h happens in an unusual place due to the
requirements of synchronization of most source files between this
project and another that does not use libiberty. It serves to pull
libiberty.h in for all source files in libctf/, which does the trick.)
Tested on x86_64-pc-linux-gnu, x86_64-unknown-freebsd12.0,

When source file path is relative to the build directory (which
is considered a good practice and is enforced in certain buildsystems,
such as meson), gdb only applies substitute-path to the build directory
path. Then gdb appends the source file path to the rewritten build
directory path, and tries to access that.
This fails if either two of the following conditions are true:
a) The user didn't specify substitute-path for the build directory.
This is highly likely, since path substitution for build directories
is not documented anywhere, and since gdb does not tell[0] the user
the path to the build directory, just the source file path.
b) The source file path changed.
This can also easily happen, since a source path that is relative
to the build directory can include any number of directory names
that are not part of the program source tree (starting with the
name of the root directory of the source tree). Gdb will not apply
substitute-path to that relative path, thus there is no way for
the user to tell gdb about these changes.
This commit changes the code to apply substitute-path to all filenames,
both relative and absolute. This way it is possible to do things like:
set substitute-path ../foobar-1.0 /src/my/foobar-1.0
which is completely in line with the user expectations.
This might break unusual cases where build directory path is also
relative (is that even possible?) and happens to match the path
to the source directory (i.e. happens to match a substitution rule).
[0]: There's a "maintenance info symtabs" command that does show the names
of the build directories, but normal users are not required to
know or use that.

Currently "maint time" will print the amount of time a command took.
Sometimes, though, it's useful to have a timestamp as well -- for
example if one is correlating a gdb log with some other log.
This patch adds a timestamp to the start and end of each command when
this setting is in effect.
This also removes a "//" comment and changes scoped_command_stats to
use DISABLE_COPY_AND_ASSIGN; two minor things I noticed while working
on the patch.

If the new GNU property section was being created by the linker
(this will happen only if none of the inputs have any GNU property
section but the command line to the linker forces a bti with
--force-bti), the alignment of the section and hence the program
header of PT_GNU_PROPERTY type was not being set correctly. This
patch fixes this issue.

If the RISC-V prologue scanner finds a 6 or 8 byte instruction we
currently throw an internal error, which is not great for the user.
A mechanism already exists in the prologue scanner to leave
instructions marked as unknown so that we can stop the prologue scan
without raising an error, this is used for all 2 and 4 byte
instructions that are not part of the small set the prologue scanner
actually understands.
This commit changes GDB so that all 6 and 8 byte instructions are
marked as unknown, rather than causing an error.

Adds an utility function to make it shorter to write the common case
of wrapping an xstrdup with a unique_xmalloc_ptr, and uses it
throughout.
Note: I tried to put this in common/common-utils.h near skip_spaces,
etc. but that is included in common/common-defs.h before
common/gdb_unique_ptr.h is included, so it would fail to compile
because gdb::unique_xmalloc_ptr isn't defined at that point yet. I
tried moving the gdb_unique_ptr.h inclusion before common-utils.h, but
that doesn't work because gdb_unique_ptr.h depends on common-utils.h
for xfree.

Factorizes the testing of the help output, by having a single place
that defines the common help trailer and/or prefix messages.
|
|
The "help" command can output long list of command names or classes.
Use the title style to style the command names or classes to make
the output more readable.
Similarly, change "apropos" command to also style the command names.
It is sometimes unclear why "apropos REGEXP" lists some commands,
and then the user has to manually do 'help command' for all commands
listed by "apropos" to see more details about the matching commands.
=> Add an optional flag -v so that "apropos -v REGEXP":
* outputs the full documentation of matching commands.
* highlights the documentation parts matching REGEXP.
|

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.
