So the problem here is EXPAND_INTER_MACRO_16 expands to nothing if 16 byte FP does not
exist but we still add a comma after it and that causes a build failure.
The same is true for EXPAND_INTER_MACRO_10 too.

Committed as obvious after a bootstrap and test on x86_64-linux-gnu and aarch64-linux-gnu.

libgfortran/ChangeLog:

	PR libfortran/110759
	* ieee/ieee_arithmetic.F90
	(COMP_INTERFACE): Remove the comma after EXPAND_INTER_MACRO_16
	and EXPAND_INTER_MACRO_10.
	(EXPAND_INTER_MACRO_16): Add comma here if 16 byte fp exist.
	(EXPAND_INTER_MACRO_10): Likewise.

Those operations were added to Fortran 2018, and correspond to
well-defined IEEE comparison operations, with defined signaling
semantics for NaNs. All are implemented in terms of GCC expressions and
built-ins, with no library support needed.

On Windows, 'system' is called - that fails with -1 if the command
interpreter could not be started; on POSIX systems, if the child
process could not be started by the shell, exit(127)/_exit(127) is
called/returned. On Windows, cmd.exe (and also the PowerShell) return
errorlevel 9009.

libgfortran/ChangeLog:

	Windows, regard system()'s return value of 9009 as EXEC_INVALIDCOMMAND.

Recently, mingw-w64 has got updated <msxml.h> from Wine which is included
indirectly by <windows.h> if `WIN32_LEAN_AND_MEAN` is not defined. The
`IXMLDOMDocument` class has a member function named `abort()`, which gets
affected by our `abort()` macro in "system.h".

`WIN32_LEAN_AND_MEAN` should, nevertheless, always be defined. This
can exclude 'APIs such as Cryptography, DDE, RPC, Shell, and Windows
Sockets' [1], and speed up compilation of these files a bit.

Rotate ChangeLog files for ChangeLogs with yearly cadence.

Since GCC 12, the conversion between the array descriptors formats - the
internal (GFC) and the C binding one (CFI) - moved to the compiler itself
such that the cfi_desc_to_gfc_desc/gfc_desc_to_cfi_desc functions are only
used with older code (GCC 9 to 11).  The newly added checks caused asserts
as older code did not pass the proper values (e.g. real(4) as effective
argument arrived as BT_ASSUME type as the effective type got lost inbetween).

As proposed in the PR, revert to the GCC 11 version - known bugs is better
than some fixes and new issues. Still, GCC 12 is much better in terms of
TS29113 support and should really be used.

This patch uses the current libgomp version of the GCC 11 branch, except
it fixes the GFC version number (which is 0), uses calloc instead of malloc,
and sets the lower bound to 1 instead of keeping it as is for
CFI_attribute_other.

libgfortran/ChangeLog:

	PR libfortran/108056
	* runtime/ISO_Fortran_binding.c (cfi_desc_to_gfc_desc,
	gfc_desc_to_cfi_desc): Mostly revert to GCC 11 version for
	those backward-compatiblity-only functions.

This change adds the configury bits to activate the build of
shared libs on VxWorks ports configured with --enable-shared,
for libraries variants where this is generally supported (rtp,
code model !large - currently not compatible with -fPIC).

Set lt_cv_deplibs_check_method in libtool.m4, so the build of
libraries know how to establish dependencies.  This is useful in
configurations such as aarch64 where proper support of LSE relies
on accurate dependency information between libstdc++ and libgcc_s
to begin with.

Regenerate configure scripts to reflect libtool.m4 change.

2022-10-09  Olivier Hainque  <hainque@adacore.com>

	* libtool.m4 (*vxworks*): When enable_shared, set dynamic_linker
	and friends for rtp !large. Assume the linker has the required
	abilities and set lt_cv_deplibs_check_method.

	* config.gcc (*vxworks*): Add t-slibgcc fragment

Make sure that calling IEEE_SET_ROUNDING_MODE with RADIX=10 does not
affect the binary rounding mode.

and IEEE_SET_MODES.

libgfortran/

	* gfortran.map: Add symbols for IEEE_GET_MODES
	and IEEE_SET_MODES.

The IEEE_MODES_TYPE type and the two functions that get and set it
were added in Fortran 2018.  They can be implemented using the already
existing target-specific functions.  A future optimization could, on
some targets, set/get all modes through one or two instructions only,
but that would need a new set of functions in all config/fpu-* files.

2022-09-04  Francois-Xavier Coudert  <fxcoudert@gcc.gnu.org>

libgfortran/

	* ieee/ieee_exceptions.F90: Add IEEE_MODES_TYPE, IEEE_GET_MODES
	and IEEE_SET_MODES.
	* ieee/ieee_arithmetic.F90: Make them public in IEEE_ARITHMETIC
	as well.

Add the new IEEE_AWAY rounding mode. It is unsupported on all known
targets, but could be supported by glibc and AIX as part of the C2x
proposal. Testing for now is minimal.

Add the optional RADIX argument to IEEE_SET_ROUNDING_MODE and
IEEE_GET_ROUNDING_MODE. It is unused for now, because we do not
support radices other than 2.
