Christian Biesinger f945dedfd3 Make ada_decode not use a static buffer
This makes it safer to use in general, and also allows using it on a
background thread in the future.

Inspired by tromey's patch at:
1226cbdfa4
(however, implemented in a different way)

Christian Biesinger 626ca2c06f Replace solib_global_lookup with gdbarch_iterate_over_objfiles_in_search_order
All implementations of either function use it for the same purpose (except
Darwin, which is a no-op): to prefer a symbol in the current objfile over
symbols with the same name in other objfiles. There does not seem to be a
reason to have both mechanisms for that purpose.

gdb/ChangeLog:

2019-09-20  Christian Biesinger  <cbiesinger@google.com>

Ulrich Weigand abf516c693 Remove Cell Broadband Engine debugging support
This patch implements removal of Cell/B.E. support, including
- Support for the spu-*-* target
- Support for native stand-alone SPU debugging
- Support for integrated debugging of combined PPU/SPU applications
- Remote debugging (gdbserver) support for all the above.

The patch also removes the TARGET_OBJECT_SPU target object type,
as this is available only on Cell/B.E. targets, including
- Native Linux support
- Core file support (including core file generation)
- Remote target support, including removal of the qXfer:spu:read
  and qXfer:spu:write remote protocal packets and associated
  support in gdbserver.

Tom Tromey 78e8cb91cd Change TUI window commands to be case-sensitive
The TUI window-related commands like "focus" are case insensitive.

here.  This patch changes the TUI to be case sensitive, like the rest
of gdb.

There's no reason to call refresh in tui_resize_all.  This call

Tom Tromey 1b935acf7e Set TUI locator height to 1
The TUI has long had code to resize the locator, using 2 as the
height.  However the code has "1" in a comment, like:

    locator->resize (2 /* 1 */ ,

This patch fixes the resizing code to set the height to 1.  Doing this
revealed what was probably the reason for setting the height to 2 in
the first place: this caused the locator window to scroll.  However,
this is easily handled by calling scrollok on the locator window.

Tom Tromey 71a25ed2e7 Change tui_make_status_line to be a method
This changes tui_make_status_line to be a method on
tui_locator_window.  This is a minor cleanup.

This also changes the new method to use the locator's width, rather
than the terminal width.  This is important if we ever want to allow
windows to be made more narrow.

Tom Tromey d420769627 Fix crash in Ada "catch exception"
PR ada/24919 concerns a crash that Tom de Vries noticed when running
the "catch_ex" Ada test case.  He sent a test executable and tracked
this down to commit f21c2bd7b7 ("Fix Fortran regression with variables
in nested functions").

Looking at that patch, you can see the obvious error:

Oops!  This patch fixes the bug.

Tom de Vries f64e2f4045 [gdb] Catch exception when constructing the highlighter
Currently in source_cache::ensure we catch the exception that triggers when
highlighter->highlight is called:
...
         try
           {
             std::istringstream input (contents);
             std::ostringstream output;
             highlighter->highlight (input, output, lang_name, fullname);
...
and the file used earlier in the construction of the highlighter:
...
             highlighter = new srchilite::SourceHighlight ("esc.outlang");
...
is missing.

The fact that this exception triggers when highlighter->highlight is called is
an implementation artefact of libsource-highlight.so though, and this could be
different for older or newer versions.

Make things more robust by also catching exceptions thrown during construction
of the highlighter.  This makes the handling on master equivalent with what
has been committed for 8.3.1.

Tested on x86_64-linux.

Alan Modra fd3619828e bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions.  The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections.  Those sections shouldn't be modified
anyway.

The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma.  I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section.  This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

Tom Tromey 11061048d1 Give a name to the TUI SingleKey keymap
Readline 8.0 has a feature that lets an application name a keymap.
This in turn makes it simpler for users to bind keys in keymaps in
their .inputrc.

This patch gives a name to the TUI SingleKey keymap, so that
additional bindings can be made there.  For example:

    $if gdb
    set keymap SingleKey
    "X": "echo hello\\n\n"
    $endif

The call to rl_initialize, in tui_initialize_readline, had to be
removed so that .inputrc was not read too early.  Note that Readline

Simon Marchi f64eea3a59 gdb: remove local extern declaration of cli_styling
Following the int -> bool conversion of boolean options (commit
491144b5e2 ("Change boolean options to bool instead of int")), I see
this ASAN error:

The reason of this is that we have this declaration of cli_styling in cli/cli-style.h:

  extern bool cli_styling;

but ui-file.c uses its  own local declaration:

  extern int cli_styling;

Because of that, the code in ui-file.c thinks the variable is 4 bytes
long, when it is actually 1 byte long, so the generated code reads past
the variable.

Fix it by removing the declaration and making ui-file.c include
cli/cli-style.h.

gdb/ChangeLog:

	* ui-file.c: Include cli/cli-style.h.
	(term_cli_styling): Remove cli_styling declaration.

Mike Gulick f1b620e9b4 gdb: Look for compilation directory relative to directory search path
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.

Andrew Burgess 67f3ed6afe gdb: Catch exceptions when accessing source cache
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.

Joel Brobecker 7433218996 (Ada) do not print Ada task names in quotes in "info tasks" output
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.

Andrew Burgess ec6c8338a8 gdb: Force use of float version of log10
This commit:

  commit aa17805fb9
  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.
