These dirs don't use automake, so use AC_CONFIG_MACRO_DIRS to specify
../config as a search dir for m4 macros. This allows removal of a lot
of hand-written m4_include's from acinclude.m4 files, and simplifies
use of `aclocal` or `autoreconf` as manual -I is not needed.

offset_N uses INLINE_SIM_ENDIAN, which uses UNUSED to put the "unused"
attribute. However, it appears after the function's return type, which
seems to make it not apply to the function. Moving it to before the
return type fixes the error.

Only one arch uses this currently, but others could too. By moving
it up to the common checks, it'll also let us simplify the moxie code
significantly.
|
|
Use the same basic names as the common sim inline logic so we can
merge the two. We don't do that here, just prepare for it.
The common code seems to be based on the ppc version but with slightly
different names as it was cleaned up & generalized. I *think* these
concepts are the same, so binding them together is OK, but maybe I'm
misreading them. If so, can always tweak them later.
REVEAL_MODULE -> H_REVEALS_MODULE
INLINE_MODULE -> C_REVEALS_MODULE

The code that set & used this variable was deleted long ago,

For the ports that still don't build with -Werror, rather than disable
the flag at configure time, do it at make time. This will allow us to
unify these tests in the common sim configure script.
|
|
As we merge settings from subdirs into the common configure, we
sometimes need to keep the settings working in both dirs. Create
a makefile fragment to pass them down so we don't have to run the
checks twice. For now, the file is empty, but we'll start moving
logic in shortly.
|
|
When the same such construct is used multiple times in a source file,
there's still no need to emit a separate symbol each time. Under the
assumption that there won't be many of these, use a simple array
lookup method to record previously used symbols.
|
|
The sim-basics.h is too big and includes too many things. This leads
to some arch's sim-main.h having circular loop issues with defs, and
makes it hard to separate out common objects from arch-specific defs.
By splitting up sim-basics.h and killing off sim-main.h, it'll make
it easier to separate out the two.
|
|
This doesn't need to be included for every sim file, so drop it.
Every C file that needs it seems to already include it.
|
|
The m4 macro has 2 args: the "wire" settings (which represents the
hardwired port behavior), and the default settings (which are used
if nothing else is specified). If none are specified, the arch is
expected to support both, and the value will be probed based on the
user runtime options or the input program.
Only two arches today set the default value (bpf & mips). We can
probably let this go as it only shows up in one scenario: the sim
is invoked, but with no inputs, and no user endian selection. This
means bpf will not behave like the other arches: an error is shown
and forces the user to make a choice. If an input program is used
though, we'll still switch the default to that. This allows us to
remove the WITH_DEFAULT_TARGET_BYTE_ORDER setting.
For the ports that set a "wire" endian, move it to the runtime init
of the respective sim_open calls. This allows us to change the
WITH_TARGET_BYTE_ORDER to purely a user-selected configure setting
if they want to force a specific endianness.
With all the endian logic moved to runtime selection, we can move
the configure call up to the common dir so we only process it once
across all ports.
The ppc arch was picking the wire endian based on the target used,
but since we weren't doing that for other biendian arches, we can
let this go too. We'll rely on the input selecting the endian, or
make the user decide.

|
This define is used for a particular target and depends on the
simulated CPU hardware. It has no relation to the host CPU that
the sim is running on. So rename the common "PAGE_SIZE" here to
better reflect its usage and avoid conflicts with system headers.

Because SIGTTOU is sent to the whole process instead of to a specific
thread, consuming a pending SIGTTOU in the destructor of
scoped_ignore_sigttou could consume a SIGTTOU signal raised due to
actions done by some other thread. Simply avoid sigtimedwait in
scoped_ignore_sigttou, thus plugging the race. This works because we
know that when the thread writes to the terminal and the signal is
blocked, the kernel does not raise the signal at all.
Tested on GNU/Linux, Solaris 11 and FreeBSD.

The problem with using signal(...) to temporarily ignore a signal, is
that that changes the the signal disposition for the whole process.
If multiple threads do it at the same time, you have a race.
Fix this by using sigprocmask + sigtimedwait to implement the ignoring
instead, if available, which I think probably means everywhere except
Windows nowadays. This way, we only change the signal mask for the
current thread, so there's no race.

We currently have scoped_restore_sigttou and scoped_restore_sigpipe
doing basically the same thing -- temporarily ignoring a specific
signal.
This patch introduce a scoped_restore_signal type that can be used for
both. This will become more important for the next patch which
changes how the signal-ignoring is implemented.
scoped_restore_sigpipe is a straight alias to
scoped_restore_signal<SIGPIPE> on systems that define SIGPIPE, and an
alias to scoped_restore_signal_nop (a no-op version of
scoped_restore_signal) otherwise.
scoped_restore_sigttou is not a straight alias because it wants to

All tests in this file append to GDBFLAGS instead of overwriting it,
except the last two. I noticed because when testing with the
native-extended-remote board, it removes the "set sysroot" argument, and
it causes the test to be very long to run, due to big glibc debug info
being read through the remote target.
I think this oddity is due to a race condition between these two
commits:
[1] https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=c22261528c50f7760dd6a2e29314662b377eebb4

The first one added the two tests. The second one changes the test to
append to GDBFLAGS instead of overwriting it. But the second one was
probably written before the first one was it, so missed the new tests.
Change those two tests to be like the others.

Currently, when the focus is on the command window, we disable the
keypad. This means that when the command window has the focus, keys
such as up/down/home/end etc. are not processed by curses, and their
escape sequences go straight to readline.
A side effect of disabling keypad mode is that wgetch no longer
processes mouse escape sequences, with the end result being the mouse
doesn't work, and worse, the raw mouse escape sequences are printed on
the terminal.
This commit makes the TUI command window support the mouse as well, by
always enabling the keypad, and then to avoid losing support for
up/down browsing the command history, home/end/left/right moving the
cursor position, etc., we forward those keys as raw escape sequences
to readline. Note we don't make an effort to pass down to readline
all keys returned by curses, only the common ones that readline
understands by default. Given users can specify their own readline
bindings (inputrc file, bind utility), this approach is good in
practice, though not 100% transparent or perfect.
Note that the patch makes it so that CTLC-L is always passed to
readline even if the command window does not have the focus. It was
simpler to implement that way, and it just seems correct to me. I
don't know of a reason we shouldn't do that.
The patch improves the TUI behavior in a related way. Now we can pass
special keys to readline irrespective of which window has the focus.
First, we try to dispatch the key to a window, via
tui_displatch_ctrl_char. If the key is dispatched, then we don't pass
it to readline. E.g., pressing "up" when you have the source window
in focus results in scrolling the source window, and nothing else. If
however, you press ctrl-del instead, that results in killing the next
word in the command window, no matter which window has has focus.
Before, it would only work if you had the command window in focus.
Similarly, ctrl-left/ctrl-right to move between words, etc.
Similarly, the previous spot where we handled mouse events was
incorrect. It was never reached if the window with focus can't
scroll, which is the case for the command window. Mouse scrolling
affects the window under the mouse cursor, not the window in focus.
We now always try to dispatch mouse events.
One last bit in the patch -- now if we don't recognize the non-8-bit
curses key, then we don't pass it down to readline at all. Before
that would result in bogus characters in the input line.

AIX ld expects the section contents for relocations BFD_RELOC_PPC_TLSM
or BFD_RELOC_PPC64_TLSM to be zero.
Actually, it seems to be the case for all the TLS relocations
generated by AIX assembly but only these two are mandatory.
* config/tc-ppc.c (md_apply_fix): Adjust addend to nullify
section contents for BFD_RELOC_PPC_TLSM or
BFD_RELOC_PPC64_TLSM.
* testsuite/gas/ppc/xcoff-tlsm-32.d: New test.
* testsuite/gas/ppc/xcoff-tlsm-64.d: New test.
* testsuite/gas/ppc/xcoff-tlsm.s: New test.
* testsuite/gas/ppc/aix.exp: Run new tests.
