Takashi Yano 32401ad98e Cygwin: console: Fix issues of apps which open pty.
- After some recent changes for special keys handling break the
  apps which open pty (such as script command). If the app which
  opens pty is executed in console, the following issues occur.
    1) If the script command was started from non-cygwin shell
       (such as cmd.exe), another cygwin app started in pty slave
       cannot receive Ctrl-C.
    2) If non-cygwin app is executed in pty slave, the app which
       opened the pty (e.g. script command) crashes by Ctrl-C.
  This patch fixes these issues.

Mike Frysinger 7f674bb4da libgloss: switch to AM_PROG_AR
Now that we require Automake 1.15, we can use this macro rather than
set the tool up ourselves.  The current code doesn't properly search
for a prefixed ar tool as-is.

Mike Frysinger 8343db918f newlib: libc: move configure into top-level
This kills off the last configure script under libc/ and folds it
into the top newlib configure script.  The a lot of the logic was
already in the top configure script, so move what's left into a
libc/acinclude.m4 file.

Takashi Yano 3a6b11c697 Cygwin: pinfo: Fix exit code when non-cygwin app exits by Ctrl-C.
- Previously, if non-cygwin app exits by Ctrl-C, exit code was
  0x00007f00. With this patch, the exit code will be 0x00000002,
  which means process exited by SIGINT.

Mike Frysinger e56bdf902b libgloss: document & localize custom multi-do rule
The multi-build.in file in libgloss duplicates common multilib logic
in the root source tree.  Document it a bit, and rename the rule so
it doesn't clash with the common multi-do rule.  This will let us use
them in the same makefile so we can merge aarch64/ & arm/ up (as the
only targets that use this local multi-build.in atm).

Mike Frysinger 15d7e0d417 libgloss: finish migration to AM_PROG_AS
When merging iq2000 up a level, it included a partial conversion to

to kill off the custom LIB_AM_PROG_AS which we no longer need since
we require Automake 1.15 now.

Mike Frysinger acf642177b newlib: fix multilib libg.a parallel builds
I split libg.a out into a sep target from libc.a for the main dir in
commit f2b053f49e ("newlib: separate out
libg from libc"), but missed the multilib dirs.  That leads to an
uncommon parallel build failure:
- libc.a rule runs & finishes
- $(BUILD_MULTISUBDIR)/libc.a rule runs
  -> failure due to libg.a not yet existing
- libg.a rule runs & finishes

Split the multilib libg rule out from libc too so it can depend on the
main libg directly and avoid this race.

Takashi Yano 2f2b915505 Cygwin: pty, console: Add a workaround for GDB SIGINT handling.
- The inferior of the GDB cannot be continued after SIGINT even
  though nopass option is set. This seems because cygwin GDB does
  not support hooking cygwin signal. Therefore, a workaround for
  GDB is added. With this patch, only CTRL_C_EVENT is sent to the
  GDB inferior by Ctrl-C and sending SIGINT is omitted. Note that
  "handle SIGINT (no)pass" command does not take effect even with
  or without this patch.

Takashi Yano d2b14c303c Cygwin: console: Redesign handling of special keys.
- This patch rearranges the cooperation between cons_master_thread,
  line_edit, and ctrl_c_handler so that only one of them operates
  at the same time. Since these handle Ctrl-C individually, so the
  signal may be sent multiple times to the process. This patch fixes
  the issue.

Johannes Schindelin 4ec08891a0 Cygwin: Implicitly support the /dev/fd symlink and friends
Bash has a very convenient feature that is called process substitution
(e.g. `diff -u <(seq 0 10) <(seq 1 11)`). To make this work, Bash
requires the `/dev/fd` symlink to exist, and Cygwin therefore creates
this symlink (together with the `stdin`, `stdout` and `stderr` ones)
upon start-up.

This strategy is incompatible with the idea of providing a subset of
Cygwin in a `.zip` file (because there is no standard way to represent
symlinks in `.zip` files, and besides, older Windows versions would
potentially lack support for them anyway).

That type of `.zip` file is what Git for Windows wants to use, though,
bundling a minimal subset for third-party applications in MinGit (see
https://github.com/git-for-windows/git/wiki/MinGit for details).

Let's side-step this problem completely by creating those symlinks
implicitly, similar to the way `/dev/` is populated with special
devices.

Remove dependency on __sdidinit member of struct _reent to check
object initialization. Like __sdidinit, the __cleanup member of
struct _reent is initialized in the __sinit() function. Checking
initialization against __cleanup serves the same purpose and will
reduce overhead in the __sfp() function in a follow up patch.

- This patch fixes the handle leak which occurs when exec() fails
  with an error. The duplicated handles will be closed when the
  exec'ed process is terminated. However, if exec() fails, the code
  path does not reach to the code closing the duplicated handles.
  To implement this fix more appropriately, the setup, cleanup and
  closing pty codes which was previously located in spawn.cc are
  encapsulated into the fhandler_pty_slave class functions.

Takashi Yano fc26624377 Cygwin: console: Call fix_tab_position() only if having broken tabs.
- Calling fix_tab_position() is necessary in Windows 10 with xterm
  compatible mode enabled, because it has a problem that the tab
  positions will be broken when the window size is changed. Fortunately,
  this problem has been fixed in Windows 11. Therefore, with this patch,
  necessity of fix_tab_position() call is determined by referring to
  wincap.has_con_broken_tabs(), which is recently introduced.

Takashi Yano 29d8a83008 Cygwin: console: Rearrange set_(in|out)put_mode() calls.
- With this patch, all set_(in|out)put_mode() calls are rearranged
  as follows.

  1) Setup for cygwin apps, started from non-cygwin app, is done
     in fhandler_console::post_open_setup(), which overrides
     fhandler_base::post_open_setup() called from dtable.cc.
  2) Cleanup for cygwin app is done in fhandler_console::close().
  3) Setup for cygwin apps is also in fhandler_console::bg_check(),
     which overrides fhandler_termios::bg_check(). This is called
     on read(), write() and select() for console. It is necessary
     if cygwin and non-cygwin apps are started simultaneously in
     the same process group.
  4) Setup for non-cygwin apps is done in spawn.cc via
     fhandler_console::setup_console_for_non_cygwin_app().
  5) Cleanup for non-cygwin app is done in spawn.cc vid
     fhandler_console::cleanup_console_for_non_cygwin_app().
  6) Setup for non-cygwin app started by GDB is done in
     fhandler_console::set_console_mode_to_native().
  7) No explicit cleanup for non-cygwin app started by GDB, because
     console mode is automatically reset to tty::cygwin on read()/
     write() in GDB thanks to 3).

Mike Frysinger 416792d59a newlib: libc: delete crt0.o duplication
The crt0.o was handled in a subdir-by-subdir basis: it would be compiled
in one (e.g. libc/sys/$arch/), then copied up one level (libc/sys/), then
copied up another (libc/) before finally being copied & installed in the
top newlib dir.  The libc/sys/ copy was cleaned up, and then the top dir
was changed to copy it directly out of the libc/sys/$arch/ dir.  But the
libc/sys/ copy to libc/ was left behind.  Clean that up now too.

Mike Frysinger 56c65fb8d9 newlib: posix: use local includes for local headers
These headers aren't installed, so use "" includes instead of <> so
we don't search system header paths.  This matches the style used
elsewhere in the tree for these local headers, and makes it work
w/out explicit -I flags (as needed with non-recursive make).

Mike Frysinger ac9f8c46b1 newlib: libm: merge build up a directory
Convert all the libm/ subdir makes into the top-level Makefile.  This
allows us to build all of libm from the top Makefile without using any
recursive make calls.  This is faster and avoids the funky lib.a logic
where we unpack subdir archives to repack into a single libm.a.  The
machine override logic is maintained though by way of Makefile include
ordering, and source file accumulation in libm_a_SOURCES.

One thing to note is that this will require GNU Make because of:
	libm_a_CFLAGS = ... $(libm_a_CFLAGS_$(subst /,_,$(@D)))
This was the only way I could find to supporting per-dir compiler
settings, and I couldn't find a POSIX compatible way of transforming
the variable content.  I don't think this is a big deal as other
Makefiles in the tree are using GNU Make-specific syntax, but I call
this out as it's the only one so far in the new automake code that
I've been writing.

Automake doesn't provide precise control over the output object names
(by design).  This is fine by default as we get consistent names in all
the subdirs: libm_a-<source>.o.  But this relies on using the same set
of compiler flags for all objects.  We currently compile libm/common/
with different optimizations than the rest.

If we want to compile objects differently, we can create an intermediate
archive with the subset of objects with unique flags, and then add those
objects to the main archive.  But Automake will use a different prefix
for the objects, and thus we can't rely on ordering to override.

But if we leverage $@, we can turn Automake's CFLAGS into a multiplex
on a per-dir (and even per-file if we wanted) basis.  Unfortunately,
since $@ contains /, Automake complains it's an invalid name.  While
GNU Make supports this, it's a POSIX extension, so Automake flags it.
Using $(subst) avoids the Automake warning to get a POSIX compliant
name, albeit with a GNU Make extension.

Mike Frysinger 48942fe31a newlib: powerpc: switch to Automake conditionals
Using xxx_LIBADD, xxx_DEPENDENCIES, and EXTRA_xxx_SOURCES is one way of
conditionally including files into a target.  But it's meant more for the
cases where the variables added to LIBADD & DEPENDENCIES are constructed
via substitution (e.g. AC_SUBST) or other dynamic methods.  With Automake
conditionals, then the much simpler form is to conditionally append to
the xxx_SOURCES variable and let Automake sort everything out.

Mike Frysinger e0c0ad8268 libgloss: build with -nostdinc
We don't want libgloss building against C library headers that happened

still need access to the compiler internal headers, so probe those and
include them via -isystem.  This uses a similar probing style as glibc,
which has used it for over a decade, so it should be safe & stable.

This should prevent any latent bugs due to testing with a toolchain that
is fully configured & installed already.
