Pointer comparisons after adding an offset just don't work to catch
overflow when the offset is a larger type than the pointer.
PR 25018
* dwarf.c (get_type_signedness): Delete ineffective pointer
comparison check. Properly range check uvalue offset on
recursive call.
(read_and_display_attr_value): Range check uvalue offset before
calling get_type_signedness.

gcc10 on x86_64 and powerpc64le recognises that the loop in
Foo::operator= can be turned into a call to memmove, which then
results in an undefined symbol when linking. Avoid that by making the
loop smaller.
* testsuite/ld-srec/sr3.cc (FOO_MSG_LEN): Set to 4.

We currently run into:
...
248 n = callee1 (n + l5);
(gdb) PASS: gdb.base/restore.exp: caller5 calls callee1; return callee now
print l1
$51 = <optimized out>
(gdb) FAIL: gdb.base/restore.exp: caller5 calls callee1; return restored l1 \
to 32492
...
The problem is that we try to access the value of l1 in function caller5, but
variable l1 has no DW_AT_location attribute. Since l1 is declared using the
register keyword, it's valid for gcc to emit no DW_AT_location at -O0.
Change the FAIL into an UNSUPPORTED.
Tested on x86_64-linux.
gdb/testsuite/ChangeLog:
2019-09-22 Tom de Vries <tdevries@suse.de>
* gdb.base/restore.exp: Allow register variables to be optimized out at
-O0.

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.

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.

The TUI window-related commands like "focus" are case insensitive.
This is not the norm in gdb, and I don't see a good reason to have it
here. This patch changes the TUI to be case sensitive, like the rest
of gdb.

Commit e594a5d1 ("Turn two locator functions into methods") turned
set_locator_fullname into a method on tui_locator_window. I missed it

There's no reason to call refresh in tui_resize_all. This call
flushes the curses window contents to the terminal -- but, because
we're about the resize all the windows, we're going to be sending more

* tui/tui-win.c (tui_resize_all): Don't call refresh.

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.
gdb/ChangeLog
2019-09-20 Tom Tromey <tom@tromey.com>
* tui/tui-win.c (tui_resize_all, tui_adjust_win_heights): Use 1 as

This simplifies TUI disassembly somewhat, by removing manual memory

tui_source_window_base::show_source_content is not used outside the
class any more, so this makes it private. Examining the callers shows
that it can't be called without source contents, so it can be
simplified as well.

A couple of spots in tui-layout.c still call the show_source_content
method. However, now that re-rendering is done by the resize method,
these calls are no longer needed.

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.

This changes tui_make_status_line to return std::string. This cleans
it up a bit, and removes some explicit memory management.

The "fullname" field in tui_source_window_base is only used by one
subclass. This patch moves the field to that subclass, and changes it
to be a unique_xmalloc_ptr.

The calls to tui_clear_source_windows_detail in tui_add_win_to_layout
aren't needed, because (after the resize unification) resizing will
update the window contents. Removing these calls lets us remove
several other things as well.

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:
- return 0;
+ return true;
Oops! This patch fixes the bug.
Tested on x86-64 Fedora 29.

This one exposed a bug in tic6x gas, found with inline function
parameter type checking. struct bfd_section and struct bfd_symbol

symbols.
