branch. Because the rebase process required re-writing some of the
commit history (due to some code being moved around upstream), this
doesn't merge cleanly, and some manual merge resolution was neccesary.

- Fix for bug relating to incorrect encoding of ALU sign and zero extend operations.
- Fix for bug relating to incorrect HWLP branch offset upper boundaries.
- Fix general white space and number formatting inconsistencies.

The variable right_lib_flags is not being set correctly to define RIGHT.
The value RIGHT is needed to force the address of the library functions
lib1_func3 and lib2_func4 to occur at different address in the wrong and
right libraries.

With RIGHT defined correctly, functions lib1_func3 and lib2_func4 occur
at different addresses the test runs correctly on Powerpc.

The test needs the lib2 addresses to be different in the right and
wrong cases.  That is the point of introducing function lib2_spacer
with the ifdef RIGHT compiler directive.

On Intel, the ARRAY_SIZE of 1 versus 8192 is sufficient to get the
dynamic linker to move the addresses of the library.  You can also get
the same effect on PowerPC but you must use a value much larger than
8192.

The key thing is that the test was not properly setting RIGHT to
defined to get the lib2_spacer function on Intel and Powerpc.

Without the patch, we have the Intel backtrace for the bad libraries:

backtrace
#0  break_here () at /home/ ... /gdb/testsuite/gdb.base/solib-search.c:30
#1  0x00007ffff7fae156 in ?? ()

#9  0x0000555555555156 in main () at /home/ ... /binutils-gdb/gdb/testsuite/gdb.base/solib-search.c:23
Backtrace stopped: previous frame inner to this frame (corrupt stack?)
(gdb) PASS: gdb.base/solib-search.exp: backtrace (with wrong libs) (data collection)

The backtrace on Intel with the good libraries is:

backtrace
#0  break_here () at /.../binutils-gdb/gdb/testsuite/gdb.base/solib-search.c:30
#1  0x00007ffff7fae156 in lib2_func4 () at /.../binutils-gdb/gdb/testsuite/gdb.base/solib-search-lib2.c:49

#4  0x00007ffff7fbb146 in lib1_func1 () at /.../gdb.base/solib-search-lib1.c:30
#5  0x0000555555555156 in main () at /...solib-search.c:23
(gdb) PASS: gdb.base/solib-search.exp: backtrace (with right libs) (data collection)
PASS: gdb.base/solib-search.exp: backtrace (with right libs)

In one case the backtrace is correct and the other it
is wrong on Intel.  This is due to the fact that the ARRAY_SIZE caused
the dynamic linker to move the library function addresses around.  I
believe it has to do with the default size of the data and code
sections used by the dynamic linker.

So without the patch the backtrace on PowerPC looks like:

 backtrace
#0  break_here () at /.../solib-search.c:30
#1  0x00007ffff7f007f4 in lib2_func4 () at /.../solib-search-lib2.c:49
#2  0x00007ffff7f307f4 in lib1_func3 () at /.../solib-search-lib1.c:49
#3  0x00007ffff7f007ac in lib2_func2 () at /.../solib-search-lib2.c:30
#4  0x00007ffff7f307ac in lib1_func1 () at /.../solib-search-lib1.c:30
#5  0x000000001000074c in main () at /.../solib-search.c:23

for both the good and bad libraries.

The patch fixes defining RIGHT in solib-search-lib1.c and solib-search-
lib2.c.  Note, without the patch the lib1_spacer and lib2_spacer
functions do not show up in the object dump of the Intel or Powerpc
libraries as it should.  The patch fixes that by making sure RIGHT gets
defined.

Now with the patch the backtrace for the bad library on PowerPC looks
like:

backtrace
#0  break_here () at /.../solib-search.c:30
#1  0x00007ffff7f0083c in __glink_PLTresolve () from /.../solib-search-lib2.so
Backtrace stopped: frame did not save the PC

And the backtrace for the good libraries on PowerPC looks like:

backtrace
#0  break_here () at /.../solib-search.c:30
#1  0x00007ffff7f0083c in lib2_func4 () at /.../solib-search-lib2.c:49
#2  0x00007ffff7f3083c in lib1_func3 () at /.../solib-search-lib1.c:49
#3  0x00007ffff7f007cc in lib2_func2 () at /.../solib-search-lib2.c:30
#4  0x00007ffff7f307cc in lib1_func1 () at /.../solib-search-lib1.c:30
#5  0x000000001000074c in main () at /.../solib-search.c:23
(gdb) PASS: gdb.base/solib-search.exp: backtrace (with right libs) (data collection)
PASS: gdb.base/solib-search.exp: backtrace (with right libs)

The issue then is on Power where the ARRAY_SIZE of 1 versus 8192 is not
sufficient to cause the dymanic linker to allocate the libraries at
different addresses.  I don't claim to understand the specifics of how
the dynamic linker works and what the default size is for the data and
code sections are.  My guess is by default PowerPC allocates a larger
data size by default, which is large enough to hold array[8192].  The
default size of the data section allocated by the dynamic linker on
Intel is not large enough to hold array[8192] thus causing the code
section on Intel to have to move when the large array is defined.

Note on PowerPC, if you make ARRAY_SIZE big enough, then you will cause
the library addresses to occur at different addresses as the larger
data section forces the code section to a different address.  That was
actually my original fix for the program until I spoke with Doug Evans
who originally wrote the test.  Doug noticed that RIGHT was not getting
defined as he originally intended in the test.

With the patch to fix the definition of RIGHT, PowerPC has a bad and a
good backtrace because the address of lib1_func3 and lib2_func4 both
move because lib1_spacer and lib2_spacer are now defined
before lib1_func3 and lib2_func4.

Without the patch, the lib1_spacer and lib2_spacer function doesn't show
up in the binary for the correct or incorrect library on Intel or PowerPC.
With the patch, RIGHT gets defined as originally intended for the test on
both architectures and lib1_spacer and lib2_spacer function show up in the
binaries on both architectures changing the other function addresses as
intended thus causing the test work as intended on PowerPC.

This can be a local in dwarf_decode_line_header.

This doesn' have to be a field, it can simply be a local variable in
dwarf_decode_line_header.  Name the local variable "unit_length", since
that's what the field in called in DWARF 4 and 5.  It's always easier to
follow the code with the standard on the side when we use the same
terminology.

Commit c67f4e53 ("gdb/testsuite: make gdb.ada/mi_prot.exp stop at
expected location") introduced some DUPLICATEs in MI tests using
mi_continue_to_line, for example:

    DUPLICATE: gdb.ada/mi_ref_changeable.exp: mi_continue_to_line: set temporary breakpoint

These test names were previously differentiated by the location passed
to mi_continue_to_line.  Since the location can contain a path, that
commit removed the location from the test name, in favor of a hardcoded
string "set temporary breakpoint", hence removing the differentiator.

mi_continue_to_line receives a "test" parameter, containing a test
name.  Add a "with_test_prefix" with that name, so that all tests
recorded during mi_continue_to_line have this in their name.

mi_continue_to_line passes that "test" string to mi_get_stop_line, that
is a bit superfluous.  mi_get_stop_line only uses that string in case of
failures (it doesn't record a pass if everything goes fine).  Since it's
not crucial, just remove it, and adjust all callers.

Adjust three gdb.mi/mi-var-*.exp tests to use prefixes to differentiate
the multiple calls to mi_run_inline_test (which calls
mi_continue_to_line).

Internally we noticed that some tests would fail like so on Windows:

warning: Section .debug_aranges in [...] has duplicate debug_info_offset 0x0, ignoring .debug_aranges.

Debugging showed that, in fact, a second CU was being created at this
offset.  We tracked this down to the fact that, while the ELF reader
is careful to re-use the per-BFD data, other readers are not, and
could re-read the DWARF data multiple times.

However, since the change to allow an objfile to have multiple "quick
symbol" implementations, there's no reason for this approach -- it's
safe and easy for all symbol readers to reuse the per-BFD data when
reading DWARF.

This patch implements this idea, simplifying dwarf2_build_psymtabs and
making it private, and then switching to dwarf2_initialize_objfile as
the sole way to start the DWARF reader.

Note that, while I think the call to dwarf2_build_frame_info in
machoread.c is also obsolete, I haven't attempted to remove it here.

The following behaviour was observed in GDB:

  (gdb) show remote X-packet
  Support for the `p' packet is auto-detected, currently unknown.

Note the message mentions the 'p' packet.  This is a regression since
this commit:

  commit 8579fd13
  Date:   Mon Nov 8 14:58:46 2021 +0000

      gdb/gdbsupport: make xstrprintf and xstrvprintf return a unique_ptr

Before this commit the behaviour was:

  (gdb) show remote X-packet
  Support for the `X' packet is auto-detected, currently unknown.

The problem was caused by a failed attempt to ensure that some
allocated strings were deleted when GDB exits.  The code in the above
commit attempted to make use of 'static' to solve this problem,
however, the solution was just wrong.

In this new commit I instead allocate a static vector into which all
the allocated strings are stored, this ensures the strings are
released when GDB exits (which makes output from tools like valgrind
cleaner), but each string within the vector can be unique, which fixes
the regression.

In this review [1], Eli pointed out that we should be careful when
concatenating file names to avoid duplicated slashes.  On Windows, a
double slash at the beginning of a file path has a special meaning.  So
naively concatenating "/"  and "foo/bar" would give "//foo/bar", which
would not give the desired results.  We already have a few spots doing:

  if (first_path ends with a slash)
    path = first_path + second_path
  else
    path = first_path + slash + second_path

In general, I think it's nice to avoid superfluous slashes in file
paths, since they might end up visible to the user and look a bit
unprofessional.

Introduce the path_join function that can be used to join multiple path
components together (along with unit tests).

I initially wanted to make it possible to join two absolute paths, to
support the use case of prepending a sysroot path to a target file path,
or the prepending the debug-file-directory to a target file path.  But
the code in solib_find_1 shows that it is more complex than this anyway
(for example, when the right hand side is a Windows path with a drive
letter).  So I don't think we need to support that case in path_join.
That also keeps the implementation simpler.

Change a few spots to use path_join to show how it can be used.  I
believe that all the spots I changed are guarded by some checks that
ensure the right hand side operand is not an absolute path.

Regression-tested on Ubuntu 18.04.  Built-tested on Windows, and I also
ran the new unit-test there.

The gdb_test_multiple pattern for the "notice empty URL" test in
gdb.debuginfod/fetch_src_and_symbols.exp misses expecting the prompt.
Fix it by using -re -wrap.

Also, by using "confirm off", the message GDB prints if Debuginfod
downloading is available doesn't contain "Enable debuginfod" any
longer.  E.g.:

Following a7e6a19e "gdb: testsuite: add
new gdb_attach to check "attach" command", this commit proposes to
introduce the gdb_spawn_attach_cmdline helper and use it in
gdb.base/attach.exp.

This helper starts GDB and adds the "--pid=$PID" argument.

Also note that both the original and new implementation use
gdb_spawn_with_cmdline_opts, which in the end uses default_gdb_spawn.
This makes sure that we use $INTERNAL_GDBFLAGS, which by default already
contain "-iex \"set height 0\" -iex \"set width 0\"".  To avoid
repetition of those arguments, gdb_spawn_attach_cmdline does not repeat
those arguments.

To maintain a behavior similat to what gdb.base/attach.exp used to do,
gdb_spawn_attach_cmdline keeps the -quiet flag.

This turns symbol_symtab into a method on symbol.  It also replaces

This turns symbol_arch into a method on symbol.

This turns symbol_objfile into a method on symbol.

Symbols have an aclass_index method, but this isn't needed, because
the aclass index isn't useful outside of the symbol implementation.
