Explicitly call rl_resize_terminal() in TUI's SIGWINCH handler
In readline 6.3, the semantics of SIGWINCH handling has changed.
When a SIGWINCH signal is raised, readline's rl_sigwinch_handler() now
does not immediately call rl_resize_terminal(). Instead it sets a flag
that is checked by RL_CHECK_SIGNALS() at a point where readline has
control, and calls rl_resize_terminal() if said flag is set.
This change is item (c) in https://cnswww.cns.cwru.edu/php/chet/readline/CHANGES
c. Fixed a bug that caused readline to try and run code to modify its idea
of the screen size in a signal handler context upon receiving a SIGWINCH.
This change in behavior is important to us because TUI's
tui_sigwinch_handler() relies on the assumption that by the time it's
called, readline will have updated its knowledge of the terminal
dimensions via rl_resize_terminal(). Since this assumption no longer
holds true, TUI's SIGWINCH handling does not work correctly with
readline 6.3.
To fix this issue this patch makes TUI explicitly call
rl_resize_terminal() in tui_async_resize_screen() at the point where
current terminal dimensions are needed. (We could call it in
tui_sigwinch_handler too, but since readline avoids doing it, we are
probably safer off avoiding to call it in signal handler context as
well.) After this change, SIGWINCH handling continues to work properly
with both readline 6.2 and 6.3.
Since we no longer need it, we could now explicitly disable readline's
SIGWINCH handler by setting rl_catch_sigwinch to zero early on in the
program startup but I can't seem to find a good spot to place this
assignment (the first call to rl_initialize() occurs in
tui_initialize_readline() so the assignment should occur before then),
and the handler is harmless anyway.

* tui/tui-win.c (tui_async_resize_screen): Call
rl_resize_terminal().

Subsequently, the call to ContinueDebugEvent will fail, because we're trying to

that will never come.
This patch doesn't fix the problem, it just adds appropriate error handling.
Using error() seems appropriate here, if ContinueDebugEvent() fails, the

Rewrite relro adjusting code
The linker tries to put the end of the last section in the relro
segment exactly on a page boundary, because the relro segment itself
must end on a page boundary. If for any reason this can't be done,
padding is inserted. Since the end of the relro segment is typically
between .got and .got.plt, padding effectively increases the size of
the GOT. This isn't nice for targets and code models with limited GOT
addressing.
The problem with the current code is that it doesn't cope very well
with aligned sections in the relro segment. When making .got aligned
to a 256 byte boundary for PowerPC64, I found that often the initial
alignment attempt failed and the fallback attempt to be less than
adequate. This is a particular problem for PowerPC64 since the
distance between .got and .plt affects the size of plt call stubs,
leading to "stubs don't match calculated size" errors.
So this rewrite takes a direct approach to calculating a new relro
base. Starting from the last section in the segment, we calculate
where it must start to position its end on the boundary, or as near as
possible considering alignment requirements. The new start then
becomes the goal for the previous section to end, and so on for all
sections. This of course ignores the possibility that user scripts
will place . = ALIGN(xxx); in the relro segment, or provide section
address expressions. In those cases we might fail, but the old code
probably did too, and a fallback is provided.

sim: mcore: drop watchpoint/dumpmem/clearstats support
In preparation for converting to the common memory framework, the custom
commands get in our way. But when we realize that gdb support has been
dropped for mcore, it makes things a bit easier: the main runner does not
let you run arbitrary commands once simulation starts.
So lets disable watchpoint support until it can be converted to the common
watchpoint logic. There's already an ifdef to let us do that.
We straight up drop support for the dumpmem command (no other sim supports
this, and if it's a feature people want, we can add a common func) and the
clearstats command (not a big deal -- just restart your simulation).
We leave in place the verbose check points as a follow up commit will cut
that over to common logic.
