When making inferior function calls GDB sets up a dummy code region on
the stack, and places a breakpoint within that region. If the random
stack contents appear to be a compressed instruction then GDB will
place a compressed breakpoint, which can cause problems if the target
doesn't support compressed instructions.
This commit prevents this issue by writing a 4-byte nop instruction to
the dummy region at the time the region is allocated. With this nop
instruction in place, when we come to insert the breakpoint then an
uncompressed breakpoint will be used.
This is similar to other targets, for example mips.

instruction to the dummy code region.

I noticed that ARI mentions "ISO C 90", but now gdb uses C++11. This
patch updates some text to reflect this change.
I also noticed that a few rules can be removed now. ARGSUSED doesn't
seem to be an issue any more (there's no code mentioning this and I
doubt most of us even remember this convention); PARAMS was specific
to K&R C; and __func__ is available in C++11.

This patch changes the eBPF CPU description to prefer the register

This patch supports using pcrel instructions in TLS code sequences. A
number of new relocations are needed, gas operand modifiers to
generate those relocations, and new TLS optimisation. For
optimisation it turns out that the new pcrel GD and LD sequences can
be distinguished from the non-pcrel GD and LD sequences by there being
different relocations on the new sequence. The final "add ra,rb,13"
on IE sequences similarly needs a new relocation, or as I chose, a
modification of R_PPC64_TLS. On pcrel IE code, the R_PPC64_TLS points
one byte into the "add" instruction rather than being on the
instruction boundary.

The first two of these allow you to get function type info and args out
of the types section give a type ID: astonishingly, this was missing
from libctf before now: so even though types of kind CTF_K_FUNCTION were
supported, you couldn't find out anything about them. (The existing
ctf_func_info and ctf_func_args only allow you to get info about
functions in the function section, i.e. given symbol table indexes, not
type IDs.)
The second of these allows you to get the raw undecorated name out of
the CTF section (strdupped for safety) without traversing subtypes to
build a full C identifier out of it. It's useful for things that are
already tracking the type kind etc and just need an unadorned name.

On Windows, passing a named pipe as terminal argument to the new-ui
command does not work.
The problem is that the new_ui_command function in top.c opens the
same tty three times, for stdin, stdout and stderr. With Windows
named pipes, the second and third calls to open fail.
Opening the file only once and passing the same stream for stdin,
stdout and stderr makes it work.
Pedro says:
I tried it on GNU/Linux and things still work.
I ran all the MI tests with forced new-ui, with:
$ make check TESTS="gdb.mi/*.exp" RUNTESTFLAGS="FORCE_MI_SEPARATE_UI=1"
and saw no regressions.

An earlier patch caused tui-windata.h to be essentially empty. And,
other earlier patches implemented TUI data window methods in any spot
that happened to be convenient at the time.
This patch rearranges all the data window code to be somewhat more
organized. It moves tui_data_window to tui-regs.h, and moves the
implementation of all methods to tui-regs.c. It then removes
tui-windata.h and tui-windata.c.
It also removes the "structuring" comments from tui-regs.c; these are
not the usual gdb style, and were out of date anyhow. Finally, it
moves _initialize_tui_regs to the end of the file, per the usual gdb
convention.

A while back I changed gdb not to flush in some places. It turned out
that this broke the TUI a little. An easy way to see it is to run
"gdb -tui -nx", then "file gdb" at the gdb prompt. gdb will print the
usual "Reading symbols..." message -- but it won't appear on-screen
until the reading is complete.
This patch changes the TUI to do the equivalent of line buffering in
tui_puts_internal.

2019-07-17 Tom Tromey <tom@tromey.com>
* tui/tui-io.c (tui_puts_internal): Call wrefresh if newline is
seen.
Earlier changes made it obvious that the has_locator method can only
be called for source/disassembly windows. Because the only reference
to this now occurs in methods on this object, we can remove the
has_locator method entirely, in favor of using the member directly.
gdb/ChangeLog
2019-07-17 Tom Tromey <tom@tromey.com>
* tui/tui-win.c (tui_source_window_base::set_new_height)
(tui_source_window_base::do_make_visible_with_new_height): Use
m_has_locator field directly.
* tui/tui-data.h (struct tui_win_info) <has_locator>: Remove
method.
(struct tui_source_window_base) <has_locator>: Likewise.
tui_make_visible and tui_make_invisible are just wrappers for a method
call, so remove them and have the callers simply make the method call
themselves.

2019-07-17 Tom Tromey <tom@tromey.com>
* tui/tui-wingeneral.h (tui_make_visible, tui_make_invisible):
Don't declare.
* tui/tui-wingeneral.c (tui_make_visible, tui_make_invisible):
Remove.
* tui/tui-win.c (tui_source_window_base::set_new_height)
(tui_source_window_base::set_new_height)
(make_invisible_and_set_new_height)
(tui_source_window_base::do_make_visible_with_new_height)
(tui_source_window_base::do_make_visible_with_new_height):
Update.
* tui/tui-layout.c (show_source_disasm_command, show_data)
(show_source_or_disasm_and_command): Update.
* tui/tui-layout.c (show_layout): Update.
As with the previous patches, unifying the creation and
re-initialization cases for the data window lets us remove
make_data_window in favor of simply using "new".
gdb/ChangeLog
2019-07-17 Tom Tromey <tom@tromey.com>
* tui/tui-layout.c (make_data_window): Remove.
(show_data): Unify creation and re-initialization cases.
This unifies the remaining creation and re-initialization cases for
the source and disassembly windows. Once this is done, it's clear
that make_source_window and make_disasm_window aren't needed any more,
so remove them.

2019-07-17 Tom Tromey <tom@tromey.com>
* tui/tui-layout.c (make_source_window, make_disasm_window):
Remove.
(show_data): Unify creation and re-initialization cases.
This unifies the creation and re-initialization cases for the command
window. When this is done, it becomes clear that make_command_window
isn't needed -- it can be replaced with a simple "new", so this is
removed as well.
gdb/ChangeLog
2019-07-17 Tom Tromey <tom@tromey.com>
* tui/tui-layout.c (make_command_window): Remove.
(show_source_disasm_command, show_source_or_disasm_and_command):
Unify creation and re-initialization cases.
This changes show_source_or_disasm_and_command to unify the creation
and re-initialization cases.
gdb/ChangeLog
2019-07-17 Tom Tromey <tom@tromey.com>
* tui/tui-layout.c (show_source_or_disasm_and_command): Unify
creation and re-initialization cases.
tui_get_register returns a tui_status, but nothing checks this, so it
can return void instead.
gdb/ChangeLog
2019-07-17 Tom Tromey <tom@tromey.com>
* tui/tui-regs.c (tui_get_register): Return void.
I noticed that tui_gen_win_info::make_visible was much wordier than it
needed to be. This simplifies it.
gdb/ChangeLog
2019-07-17 Tom Tromey <tom@tromey.com>
* tui/tui-wingeneral.c (tui_gen_win_info::make_visible):
Simplify.
This is the first of a few patches to further simplify window
(re-)initialization in tui-layout.c. When changing the layout, a
window may be created or, if it already exists, simply resized. These
two cases normally are identical, but this was obscured by the way the
code was written. This patch changes show_source_disasm_command to
unify the creation and re-initialization cases.
gdb/ChangeLog
2019-07-17 Tom Tromey <tom@tromey.com>
* tui/tui-layout.c (show_source_disasm_command): Simplify window
resetting.
tui_layout_command is a simple wrapper for tui_set_layout_by_name.
This removes the extra layer and cleans up the resulting function a
bit -- changing it to call error rather than return a result. This
necessitated a small change to tui-regs.c, to avoid calling the
function that is being removed.
gdb/ChangeLog
2019-07-17 Tom Tromey <tom@tromey.com>
* tui/tui.h (tui_set_layout_by_name): Don't declare.
* tui/tui-regs.c (tui_reg_layout): New function.
(tui_show_registers, tui_reg_command): Use it.
* tui/tui-layout.c (LAYOUT_USAGE): Remove.
(tui_layout_command): Rename from tui_set_layout_by_name. Change
parameters.
(tui_layout_command): Remove.
tui_set_layout can't meaningfully be called with UNDEFINED_LAYOUT; and
instead of trying to handle this case, simply assert and have the
function return void. No caller was checking the return value anyway.
gdb/ChangeLog
2019-07-17 Tom Tromey <tom@tromey.com>
* tui/tui-layout.h (tui/tui-layout): Return void.
* tui/tui-layout.c (tui_set_layout): Return void. Add assert.
