- Basically maintain a hidden DIR* inside fhandlers.
- lseek has to be tweaked to allow basic seeking on the directory
descriptor.
- the current implementation does not keep the dir positions
between duplicated descriptor in sync. In fact, every descriptor
keeps its own copy of the DIR* and after dup/fork/exec, the
directory position is reset to 0, i. e., to the start of the
directory, as if rewinddir() has been called on the new descriptors.
While this behaviour isn't yet covered by the Issue 8 draft,
a bug report along these lines exists and will probably be
picked up for TC1.

The content of DIR should never have been exposed into userspace.
Move struct __DIR to local dirent.h and only keep forward declaration
in exported dirent.h.
This allows to tweak the structure in future, for instance, to
add thread-safety.

This change is in preparation of adding posix_getdents() from
the upcoming POSIX Base Specification Issue 8.
- Add d_reclen
- Add GLibC compatible test macros for dirent members
- Bump dirent version
- Set d_reclen to the fixed size of the dirent struct
We can do that because the size is a multiple of 8, so it fits
snugly in the buffer filled by posix_getdents and keep the
alignement.

const char *getlocalename_l(int category, locale_t locobj);
Most notably, we need a per-thread space to store the string
returned if locobj is LC_GLOBAL_LOCALE. No errors are defined
for getlocalename_l. So we can't use buffer allocation which
might lead to an ENOMEM error. We have to use a "static" buffer
in the per-thread state.
Note that the feature test macro in locale.h is not quite correct.

If specified, use __builtin_dynamic_object_size() instead of
__builtin_object_size() if supported (GCC 12.0 or later).
This enables buffer overflow checks if the buffer size is non-const
but known during runtime.
Use new macro __ssp_bos_known() instead of the (bos(p) != (size_t)-1)
checks. The latter is no longer a compile time constant in all cases.
This avoids the generation of unused code.

So far the global variable in_forkee only indicated if the
process is the child process during fork(2) itself.
However, we need an indicator accessible from plain C code
in newlib, allowing to check for a process being a forked
process all the time, after fork(2) succeeded.
Redefine bool in_forkee to int __in_forkee to allow exposing
it to newlib. Redefine how it indicates fork state (not
forked, forking, forked).

A process which is exiting due to a core dumping signal doesn't
propagate the correct exist status after dumping core, because 'dumper'
itself forcibly terminates the process.
Use 'dumper -n' to avoid killing the dumped process, so we continue to
the end of signal_exit(), to exit with the 128+signal exit status.
Busy-wait in exec_prepared_command() in an attempt to reliably notice
the dumper attaching, so we don't get stuck there.

This patch is required to fix how the newlib headers are installed
when using a sysroot install directory.
The cross compiler expects headers to be in
.../host/usr/arm-none-eabi/sysroot/usr/include/newlib.h
by default newlib installed the headers into
.../host/usr/arm-none-eabi/sysroot/usr/arm-none-eabi/include/newlib.h
${exec_prefix} provides the .../host/usr/arm-none-eabi/sysroot path
${target_noncanonical} provides an extra arm-none-eabi/ that must be removed.
With this patch, users can specify the tooldir path that is needed.

Strip a few more instructions from crt0-minrt.S:
- Remove "halt" and rely on the infinite loop after main()'s return.
- Remove main()'s argc and argv argument initialization. Host loader
does not set them, and typical firmware does not use them, either.
- Remove the __dso_handle symbol.
This should be safe because the default crt0.S is fully standards
compliant. Whereas crt0-minrt.S has been documented from the beginning
to intentionally miss features in order to reduce firmware size, while
still enabling typical PRU firmware to operate.

Avoid a recursive make to speed things up a bit. This change was
inspired by the recent similar patch for c6x:
https://sourceware.org/pipermail/newlib/2023/020869.html
While at it, fork crt0-minrt.S into a separate source file instead of
relying on a predefined macro to generate two different object files.
This improves clarity, simplifies the build rules, and would allow
further optimization in crt0-minrt.S to be implemented more cleanly.

Commit 3f3bd10104 ("* Throughout, use __try/__except/__endtry blocks [...]")
introduced setting EINVAL, marked as "Diagnosis". The reason
for this is lost in time and space, but looks very much like
a debug helper which was supposed to be removed before release.
It's rather pointless, so remove it.

When creating a split manual with one-node-per-page, the main index.html
ends up getting clobbered by the page for the index() function because
it uses "@node index" which, for html, also creates an index.html page.
To remedy this, add "Function " to every function node so now we output
"Function-index.html" and avoid clobbering. It also namespaces every
other function and helps make sure we don't clobber anything else.
Otherwise, there isn't really much rendering difference as @node text
is mostly internal. Node title text comes from @section instead.
The generated function documentation makes sure to include entries for
every function in the function index via @findex, but then the manuals
forget to actually print the index.
Wrapping the dir info with @ifnottex means it's included in all other
outputs like html which makes no sense. Switch to @direntry which is
specific for this content and is automatically written to the output
that makes sense, and omitted from the rest.
First off, afaict, xc16x support has never been merged into gcc.
Upstream merge isn't strictly required for new ports, but it seems
like people should merge eventually in some shape, and considering
the libgloss port was merged in 2009, ~14 years seems like plenty
of leeway. Which is to say, no one else can seem to build this
which makes updating & testing things very difficult.
Ignoring that, from what I can tell, this port has only ever built
and installed a crt0.o file. It defines libeval.a & libcygmon.a
targets, but nothing depends on them. The SCRIPTS & BSP variables
are always empty. The original port merge define these in the
configure script as substitutes, but never set the vars, so they
were always replaced with nothing.
I actually broke this build 2 years ago when merging the configure
up a level in commit 30f244155b
("libgloss: merge subdirs that have unique makefile_frags up a
level"). I saw that it was exporting a bunch of vars in the
configure script, but never set them, so I incorrectly assumed
they weren't used. Which means the Makefile has been setting them
to invalid values like literal @bsp_list@ and @script_list@.
Considering no one has complained, I have to assume no one cares
about this port, and we can all stop wasting time on it.

A fr30-elf build shows installed objects & libs produce same code.
A lot of code seems like it hasn't been migrated, but that's because
it's all disabled/unused (i.e. all the test & mon code). It looks
like a lot of copy & paste holdovers from the original port.
No sub-Makefile.inc file should ever set CPPFLAGS directly. That is
a global/common variable. Instead, ports should set the per-target
CPPFLAGS to include what they need.
Further, per-target CPPFLAGS should respect $(AM_CPPFLAGS).
The code was loading the common ../sbrk.c file rather than the visium
specific sbrk.c due to VPATH setup. Add an explicit rule for this one
file so we make sure the correct one is used.
